The use of a vein finder would help the nurse and phlebotomist to easily locate the vein, preventing venipuncture failure, pre-analytical error in the specimen collection and even more discomfort and pain to the patient.

Locating the vein is not easy, there are some factors that affect patients’ veins visibility such as variation on the skin of the young children (especially infants), obesity and dehydrated patients. In this case, we need a tool to help the nurse or doctor to find the vein and complete the treatment without any difficulty. Moreover, failure in venipuncture may cause thrombosis of the vein, hematoma, or even nerve injury involving the lateral antebrachial cutaneous nerve, which can lead to the so-called “causalgia” or complex regional pain syndrome.

Normally, there are two technology applied to machine which used to find the vein. One is laser technology, another is infrared technology. Both of them has pros and cons. The most famous application brand of laser technology is AccuVein, laser can penetrate the surface of the skin and show the dynamics of deep blood vessels, but maybe harm the eyes` of patients or nurses. Most of brands adopt infrared technology because of safe and stable.

Vein finder is a medical device based on the principle of the different light absorption rate between blood and surrounding tissue. In that case, this device can show veins in real time and  the medical staff as nurses and doctors can locate the vein and do all kinds of procedure more efficiently and more easily.

MGD means Meibomian gland dysfunction, is a common eye disease in nowadays` life.

With the development of technology and society, people cannot live without smart phone and computer and expose their eye to the much radiation and bacterial infection. Therefore, even 95% of people has MGD Problems.

Here are the symptom of MGD:

Blink frequently;

Dry eyes and fatigue;

Eye irritation, photophobia, soreness;

Red and swollen eyelids, conjunctival hyperemia;

Difficulty opening eyes, decreased vision;

MGD is a chronic disease caused by multiple factors, it is not easy to be cured totally. ZD Medical has three devices used for treating MGD, DRY EYE ANALYZER is used to analyze the current dry eye situation from different dimensions, such as measuring tear river height, tear film break-up time, lipid layer thickness. This ANALYZER provides a comprehensive and objective non-invasive examination for doctors to guide personalized treatment. Second device IPL is regarded as pretty effective machine to improve dry eye conditions. Normally, IPL is used for skin in most cases, our R&D team discovered and designed its new functions which is to deeply stimulate and dredge the meibomian glands, control inflammation, improve eyelid margin structure. The third device Atomizer is adopted to improve blood circulation\ relieve dry eye and reduce the breeding of bacteria and mites to enhance the stability of the tear film with the principle of vapor atomization, performing atomized ultrasonic treatment.

To some extent, MGD will be relieved with these three devices. More information please contact ZD Medical.

As we all know, training is the cornerstone of progress.

In May 14th, we had a meticulous training about the basic knowledge of OCT, the advantages of ZD OCT(Optical Coherence Tomography Angiography) 2020 among other famous brand like ZEISS PRIMUS 200, MOcean 3000, Heidelberg etc, also illustrated the definition of DRY EYE and some possible causes of DRY EYE.

This training was arranged during our CMEF Exhibition, but we still have all the passion to join this training. Through this training, we learned in what kind of situation OCT is required, we also learnt the basic structure of Retinal, we understood the working principle of OCT. For the DRY EYE devices, we have three devices in total. One is DRY EYE Detector, which is used to measure the basic conditions by several different dimensions, like BUT TIME, Tear River Height Measurement, Meibomian Gland Analysis, Fluorescence Analysis etc. The second is IPL which is used to treat DRY EYE, normally we use this machine can cure most types of DRY EYE effectively. And the last one is Atomizer, which used to relieve DEY EYES in most situations and this device is very small easy to operate which can be used at home.

After this training, we held a test and we have a really meaningful prize for the top 3. In conclusion, all the stuff learned some practical information and have a clear image about the future of our machine even the future market.

Retinal Detachment (RD) refers to the separation of retinal nerve epithelia from pigment epithelia, resulting in the inability of photoreceptor cells to properly receive and conduct light signals, which can lead to irreversible visual impairment or even blindness in severe cases. RD can be divided into three categories: porosity, tractive and exudative. Among them, rheogenic retinal detachment is the most common, accounting for more than 80%, then this article will explore in depth - rheogenic retinal detachment!

Rhegmatogenous Retinal Detachment (RRD) is a common blinding disease in ophthalmology. It is mainly caused by retinal retinal retinal retinal detachment (RRD), which is characterized by vitreous fluid penetration into the subretinal space caused by retinal pores or cracks, resulting in the separation of nerve epithelium and pigment epithelium. If not treated in time, It can lead to irreversible visual impairment and even blindness. Retinal hole formation: Common causes include retinal degeneration (e.g. lattice degeneration, cystic degeneration), high myopia (thinning of the peripheral retina due to axial elongation of the eye), eye trauma, and a history of surgery. Most of the degeneration areas are located in the peripheral retina, and most of them are in the superior temporal quadrant. Vitreous factor: vitreous liquefaction and post-detachment (PVD) is a key factor in the penetration of liquefied vitreous into the retina through the hiatus. The mechanical tug of the vitreous body on the retina can aggravate the enlargement of the hole, resulting in the extension of the detachment range.

---

01 Common causes of high myopia: the eyeball is prolonged and the retina is thinner, which makes the local hole easily formed and becomes the "entrance" of detachment. Eye trauma: Blunt trauma or penetrating injury can directly destroy the integrity of the retina, resulting in hiatus and subsequent detachment. Posterior vitreous detachment: With age or due to genetic factors, vitreous degeneration and traction lead to the appearance of the hole. Abnormal eye development: Some congenital diseases, such as familial exudative vitreoretinopathy, may also increase the risk of RRD.

02 Clinical manifestations Flashing sensation: generally appears at the edge of the visual field. Floaters: The sudden appearance of many fluttering dark shadows in front of the eyes is caused by the detachment of the vitreous body. Visual field occlusion: like a curtain or curtain, it can be stationary, or it can be expanded with the continuous expansion of the RRD range, and the central vision will be seriously decreased when the macular area is involved. Visual deformation, visual loss: some patients with chronic retinal detachment will have visual deformation, slow visual loss, etc., and some may be accompanied by vitreous bleeding.

03 Diagnostic Methods Fundus examination: After mydriasis, the range of retinal detachment and the location of the hole were observed by indirect ophthalmoscope or three mirrors. The typical manifestations were gray eminence. Optical coherence Tomography (OCT) : can visually display the structural changes of each layer of the retina to help assess the extent of detachment and macular involvement. B-ultrasonography: It is suitable for the cases where the fundus cannot be directly observed due to the opacity of the vitreous body, to provide the degree of detachment and the location of the hole. Fluorescein fundus angiography: In difficult cases to assist the identification of hiatus and its surrounding lesions, to facilitate surgical planning. Perimetry: To assist in the assessment of visual field defects, and to confirm the clinical manifestations.

In medical practice, green light (with a wavelength of about 540nm) is generally considered the color of visible light that is most helpful in locating veins. Here’s the explanation:



1. Optical principle:

• Deoxyhemoglobin in Vein Finder has a higher absorption rate of green light, while surrounding tissues (such as skin and fat) reflect more green light. This contrast between absorption and reflection makes the veins appear as dark lines under green light, making them easier to identify.
  
  In the visible spectrum, green light (520-580nm) is close to the absorption peak of deoxygenated hemoglobin, optimizing the contrast between the veins and the surrounding tissue.
  
  
  
  2. Clinical application:
  
• Medical devices (such as venous imaging AIDS) often use green LED light sources or filters, especially for patients with thin veins, darker skin or obesity.
  
• Green background light may also be used in the operating room to enhance vascular visibility and assist medical staff in operation.
  
  3. Limitations of other colors:
  
• Red light has strong penetration but low contrast, because hemoglobin absorbs less red light;
  
• Blue light scatters more, which may reduce clarity;
  
• Near-infrared light is effective, but requires imaging technology to convert to visible light, not directly belonging to the visible spectrum.
  
  

  Green light has become the preferred visible light color for assisting vein localization by enhancing the contrast between hemoglobin absorption and tissue reflection, and is widely used in clinical difficult venipentesis scenes.

According to data released by the Ophthalmology Branch of the Chinese Medical Association, the current incidence of dry eye in the world ranges from 5.5% to 33.7%, while the incidence in my country is as high as 21% to 35%. This trend has become more and more common and is developing at a younger age. The incidence of dry eye is rapidly sweeping, and it has become a phenomenon-level national eye disease with very high attention.

According to statistics from relevant experts, the number of dry eye consultations accounts for 20-30% of the number of outpatients in ophthalmology clinics. According to the actual growth data of dry eye in China from 2008 to 2013, the annual growth rate of dry eye is 114.37% of the previous year. Statistics for 2019 show that there are about 360 million people suffering from dry eye.

If you have dry eyes, congestion, or vision fluctuations; or if you have a strong foreign body sensation in your eyes due to long-term wearing of soft contact lenses; or if you are in a dry environment for a long time (or use a computer or mobile phone for a long time), your eyes will appear sore, dry and itchy, etc. Circumstance, it means you have dry eye problem.

The appearance of dry eye has little effect on patients in the initial stage. In the later stage, the damage of dry eye to the cornea will gradually appear. The common symptoms of dry eye include dry eyes, tearing, foreign body sensation, burning sensation, itching, photophobia, red jelly, blurred vision, fluctuations in vision, and 70 More than% of dry eye patients cannot read for a long time.

This shows that dry eye is a by-product of human civilization and technological progress.
