Abstract
The utility model discloses an aqueous humor is drawn materials and collection device, including former wife who has died puncture aqueous humor draw materials device and vacuum negative pressure collecting pipe, the former wife who has died punctures the aqueous humor and draws materials the device and protect pipe cap, paracentesis needle, handheld handle, aqueous humor diversion channels, aqueous humor collection needle, aqueous humor collection needle gum cover to constitute by paracentesis needle, the vacuum negative pressure collecting pipe is sealed by the rubber buffer. Get into the former wife who has died through the device puncture of drawing materials the aqueous humor, connect that the vacuum negative pressure collecting pipe realizes that the aqueous humor is drawn materials, partial shipment, collection integration, avoid complication such as the too big or uneven former wife who has died who causes of artifical swabbing pressure is sinkd, tissue lesion, effectively improve security and convenience that the aqueous humor tissue was drawn materials and was collected.
Description
Technical field
This utility model is related to technical field of medical instruments and in particular to a kind of aqueous humor is drawn materials and collection device.
Background technology
Aqueous humor is produced by ciliary epithelium, and full of back room and anterior chamber (spaces between cornea and crystalline lenses), it derives from
Blood plasma, but again embody the local tissue characteristics different from blood plasma in chemical composition, has maintenance intraocular pressure, nutrition cornea and crystalline
Body adjacent tissue simultaneously removes the critical function of vitreous body metabolite.Become including cataract, uveitis etc.
The clinical organization material indispensable with basic research field of common oculopathy, is also ocular tissue of each medical institutions biological specimen simultaneously
Most important collection object in the construction of storehouse.
However, drawing materials of aqueous humor faces many predicaments and potential safety hazard with collection.First, existing is artificial by syringe
Paracentesis of anterior chamber is drawn materials mode, even the ophthalmologist of skilled operation still inevitably runs into because swabbing pressure is excessive or not
Anterior chamber is uniformly caused to subside or the complication such as cornea, iris tissue damage.Second, the syringe of straight tube design is operated when puncturing
Space limits, and is difficult smoothly stable being drawn materials.Third, the aqueous humor tissue in inhalation syringe still manually must be carried out via assistant
Transfer and subpackage, bring the risk that portion of tissue wastes and pollutes.It would therefore be desirable to have safely and conveniently aqueous humor is drawn materials and is collected dress
Put.
At present, market does not still have the same instrument be capable of safely, conveniently carrying out the function that aqueous humor is drawn materials and collected.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of aqueous humor to draw materials and collection device, so as to
Realize safely and conveniently aqueous humor to draw materials and collecting function.
To achieve these goals, this utility model adopts the technical scheme that：
A kind of aqueous humor is drawn materials and collection device, including paracentesis of anterior chamber aqueous humor sampling device and negative pressure of vacuum collecting pipe；
Paracentesis needle 2 that described paracentesis of anterior chamber aqueous humor sampling device includes being fixedly connected sequentially, hand holding handle 3, aqueous humor draw
Circulation road 4 and humor collection pin 5, and paracentesis needle protection pipe cap 1 in described paracentesis needle 2 and permissible can be enclosed within
It is enclosed within the humor collection pin gum cover 6 on described humor collection pin 5；
Described negative pressure of vacuum collecting pipe 7 is by rubber stopper seal.
Preferably, described aqueous humor drainage passage (4) has certain radian, relatively described paracentesis needle, described radian
Between 90-150 degree.
During operation, operator holds hand holding handle, parallel for paracentesis needle iris plane is punctured and enters anterior chamber, by having one
The aqueous humor drainage channel connection determining radian carries the humor collection pin of gum cover, then humor collection is needled into negative pressure of vacuum collection
Pipe, completes aqueous humor and draws materials and collect integrated consistent operation.Need not other apparatuses and assistant, rapid and convenient.
Negative pressure of vacuum collecting pipe has standard constant negative pressure and volume, it is to avoid aqueous humor gatherer process is excessive due to swabbing pressure
Uneven cause anterior chamber to subside or cornea, iris tissue damage etc. complication.Ensure that often pipe sucks aqueous humor constant volume simultaneously,
Collection aqueous humor tissue can direct cryopreservation, it is to avoid tissue waste and pollution risk that secondary transferring and subpackage bring.

Specific embodiment
With reference to specific embodiment, this utility model is further described.
As shown in figure 1, specific embodiment of the utility model 1：A kind of aqueous humor is drawn materials and collection device, including paracentesis of anterior chamber
Aqueous humor sampling device and negative pressure of vacuum collecting pipe, paracentesis of anterior chamber aqueous humor sampling device is by paracentesis needle protection pipe cap 1, anterior chamber
Puncture needle 2, hand holding handle 3, aqueous humor drainage passage 4, humor collection pin 5, humor collection pin gum cover 6 are constituted, negative pressure of vacuum collecting pipe 7
By rubber stopper seal.
As shown in figure 1, being fixing company between paracentesis needle 2, hand holding handle 3, aqueous humor drainage passage 4 and humor collection pin 5
Connect, paracentesis needle protection pipe cap 1 can cover from paracentesis needle 2 or pull up, and humor collection pin gum cover 6 can be from aqueous humor
Collect and put on pin 5 or pull up.Drainage channel 4 adopts curved design, assumes certain radian, with paracentesis needle as reference, should
Radian be preferably provided between 90-150 so that the material-taking end of this device and collecting terminal not on one wire, relatively straight line style
Design, more mates eyeball anatomical structure, improves the convenience of operation, reduces the probability accidentally injuring its hetero-organization.
Aqueous humor collection is as follows with the operating process of collection device：
1. pull out paracentesis needle protection pipe cap, expose paracentesis needle；
2. the right hand () holds sampling device hand holding handle taking dextromanuality as a example, and adjustment anterior chamber's sky pricker inclined-plane is upwards；
3. check that humor collection pin gum cover is in place, no abjection, damaged or inclination；
4. parallel for paracentesis needle iris plane is punctured by limbus of corneae and enter anterior chamber；
5. change and hand holding handle is held by left hand, keep paracentesis needle position stable；
6. the right hand picks up negative pressure of vacuum collecting pipe, and the humor collection pin of sampling device is inserted；
7. aqueous humor flows in collecting pipe by anterior chamber via aqueous humor sampling device under the pressure-driven of negative pressure of vacuum collecting pipe,
Negative pressure in collecting pipe is gradually lowered until disappearing, and aqueous humor stops flowing out immediately；
8. aqueous humor sampling device is extracted anterior chamber in the lump together with negative pressure of vacuum collecting pipe；
9. the humor collection pin of aqueous humor sampling device is extracted from negative pressure of vacuum collecting pipe；
10. will be equipped with the negative pressure of vacuum collecting pipe cryopreservation of aqueous humor tissue, aqueous humor sampling device is integrally lost at into sharp instrument box
Reason.
Above-listed detailed description is illustrating for this utility model possible embodiments, and this embodiment simultaneously is not used to limit
