Description

A kind of medical acari taking device

Technical field

The utility model is related to clinic skin section Human Follicle Mite Infection and checks field, is specifically that one kind is directly scraped from human body skin Sebum is taken to carry out the acari taking device tool of vermiform mite inspection.

Background technology

Human Demodex is divided into two kinds of demodex folliculorum and demodex brevis, and China's infection rate is from 7.46%~91.39% , main parasitic easily causes skin in human body skin hair follicle and sebaceous glands when severe infection or concurrent bacterial infect Infringement, causes the human body demodicidosis such as brandy nose, blepharitis, dermatitis, particularly facial infection easily causes acne, to the infected Face appearance and physical and mental health cause to have a strong impact on.As the improvement of people's living standards, people increasingly focus on face The beauty health-care problem in portion, therefore, the problem of preventing and treating of human Demodex disease has become in the urgent need to address.In face inspection Human Demodex not only will be seen that the Mortality rate of vermiform mite, provide foundation for the preventing and treating of demodicidosis, and be also face One of important evidence that demodicidosis is made a definite diagnosis.Conventional inspection vermiform mite method, which is divided into, at present scrapes fat method and tape paste method.According to The instrument that can be applied to scrape in fat method of document report mainly has knife blade, tweezer formula and Wiper blade type medical area quantitative mite extracting apparatus Deng, these instruments directly from skin scraping sebum so as to quickly obtain inspection vermiform mite, but find in use, these take mite work All there is certain drawback in tool, such as check that its recall rate is low as taking mite instrument to carry out vermiform mite with knife blade, to skin generation Stimulation it is big, and further infringement may be caused to skin；Carried out with tweezer formula and Wiper blade type medical area quantitative mite extracting apparatus compacted Shape mite checks there is that recall rate is high, can calculate infectiosity, yet with general chemosterilant in a short time very It is difficult to kill acarid and bacterium, and Wiper blade type medical area quantitative mite extracting apparatus system lucite makes, it is thermo-labile, therefore can not take Quickly and thoroughly inustion sterilizes, and sterile working during Reusability continuous to this kind of acari taking device brings difficulty, and different Position also needs to use different patterns and the medical area quantitative mite extracting apparatus of size instead, so cumbersome.Tape paste method is to utilize The characteristics of vermiform mite photophobism, evening sleeps the preceding adhesive tape that quantitative area is pasted in facial different parts (volume, nose, cheek etc.), the Two day early morning removed tape-stripping microscopy on slide.This method wastes time and energy and complex operation, therefore is not suitable for clinical examination. Therefore at present be badly in need of one kind can realize simultaneously high, light to skin irritatin easy to operate, recall rate, easy quick sterilization, can be in face Any position take mite, can arbitrary area quantitative check acari taking device tool.

Utility model content

In order to overcome the design of existing product not enough, the utility model provides a kind of medical acari taking device, and the acari taking device is not only General, easy-to-use inustion quick sterilization when recall rate is high, light to skin irritatin, easy to operate and facial each position takes mite, Can arbitrary area quantitative check acari taking device tool.

The utility model solves technical problem and uses following scheme：

The utility model is a kind of medical acari taking device, mainly includes metal hand shank, is distinguished at the two ends of metal hand shank It is fixed with a roundlet steel ring and a curved metal spatula.

When scraping sebum using roundlet steel ring, cause to reduce because the pressure that steel ring is produced to human body skin is excessive to skin What skin was produced, which leads to scrape, stimulates excessive situation, reaches and allows person under inspection's pain is small, is easy to the purpose that receives, design roundlet steel ring is by table Face is smooth and hard steel wire of a diameter of 1mm is made.To make the suitable nasolabial groove of size and shape of steel ring and the physiologic curve of nasal fossa Degree, so as to reach that the acari taking device both can take the purpose of mite in forehead, cheek, lower jaw at any position of nose again, designs roundlet The internal diameter of steel ring is 6.0mm.

When scraping sebum using curved metal spatula, to reduce the pressure that is produced to human body skin by spatula scraping edge excessive Cause leading to scrape and stimulate excessive situation to skin, reach and allow person under inspection's pain is small, be easy to the purpose that receives, design spatula and skin The contact surface of skin is the smooth spill edge of shovel of thickness 1mm.To enable arc spatula in facial larger area quantitative mite, and it is small The skilful a length of 1cm, a width of 2cm for flexibly designing arc spatula.

Led in skin surface in order to measure roundlet steel ring and arc spatula and scrape mobile distance, close to arc spatula Metal handle body of rod side be labeled with 5cm graduated scales；To prevent acari taking device from being slid from hand, at the middle part of metal hand shank and Body of rod surface between rear portion is provided with anti-skidding spiral lamina.To make, the utility model is compact and flexible, it is hand-held to be easy to and carries, design The shank diameter of metal hand shank is 3mm, and body of rod length is 12cm.

The utility model tool has the advantage that：1. recall rate is high, and this teaching and research room is respectively adopted the utility model and scrapes fat method, hand Art blade scrapes fat method and tape paste method while having the disease of skin such as brandy nose, skin acne, seborrhea to 330 faces Student enrollment carries out facial vermiform mite and checks (every kind of method checks nose, volume, cheek, 4 positions of lower jaw), recall rate difference For 65.3%, 39.1% and 80.6%, the utility model scrape fat method scrape fat method with knife blade compared with difference have statistics meaning Justice (P<0.001)；2. inustion quick sterilization is easily used.Because the utility model system stainless steel makes, therefore can be using easy Quick inustion sterilizing, thus ensuring that the acari taking device continuously repeats sterile working when using, prevents cross-infection；3. take Material is in extensive range, can be in multiple position materials such as nose, cheek, lower jaw, forehead；When 4. scraping sebum, skin generation is led Scraping stimulates smaller, and person under inspection's pain is small, it is easy to receive；5. can be with quantitative check；6. the utility model is simple in construction, small volume Ingeniously, making is simple, be easy to assembly and disassembly；7. check that speed is fast, as a result can obtain immediately.The utility model can meet behaviour simultaneously Make high easy, recall rate light to skin irritatin, energy quick sterilization, can be required in any body surface quantitative mite etc..So It can apply to dept. of dermatology's Human Follicle Mite Infection patient examination.
