Abstract

The utility model provides a disposable multifunctional injector which can solve conventional technical problems such as single function and lack of continuous negative pressure conduction. The utility model is characterized in that a folding vane is arranged on the tail wing of the syringe, and at least one locating groove is arranged on at least one fin of the pintle. By arranging the folding vane on the tail wing of the syringe and arranging the locating groove on the fin of the pintle, the utility model can be applied in the negative pressure conduction. Two sides of the vane are tear string sand the lower part of the vane is a un-cutting-through notch during conduction, the two sides of the vane can be tore apart and the bottom can be connected. Extracting a fetch of the pintle to form negative pressure and inserting the vane into the locating groove can fix the pintle. The draught tube connected with the front end of the syringe is conducted to the wound of the patients to conduct the conduction, thereby achieving the purpose that injectors can be applicable in continuous negative pressure conduction.

Description

The disposable multifunction syringe

Technical field

This utility model relates to a kind of syringe, specifically to having the improvement of syringe construction now.

Background technology

Some patients need drain after operation, the similar corrugated bag structure of the shape of existing drainage device is provided with spring in the bag.During use, drainage tube inserts in patient's wound, impels a bag volume-variation by spring, makes liquid drains such as interior drain liquid of patient's wound or blood to bag thereby form negative pressure.This pocket type drainage device exists following deficiency: 1. owing to be the bag shape, volume is big, and the patient carries inconvenience.2. owing to be soft body structure, when the patient oppresses bag unintentionally, bag interior negative pressure attenuating or draining fluids are back in the wound, easily cause wound infection, rehabilitation of patients is produced adverse influence.

And existing disposable syringe only has function of injection, does not have other functions and effect, function singleness.

How by existing Register is improved design, making it have the continuous negative pressure drainage function, then is the design problem that this utility model faced.

Summary of the invention

This utility model can solve the function singleness that prior art exists, and does not have problems such as continuous negative pressure drainage function.

In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is, a kind of disposable multifunction syringe, it comprises the fin of pin select and pin select, the empennage of syringe and syringe, it is characterized in that on the empennage of syringe, being provided with collapsible blade, at least one fin of pin select, be provided with at least more than one detent.

In this utility model, also have following technical characterictic: when not using, described collapsible blade both sides are to link to each other by the tear string that is interrupted with empennage, and collapsible blade bottom is to be connected by the cut channel mouth of not cutting with empennage.

In this utility model, also have following technical characterictic: detent is arranged in spacing at fin.

In this utility model, also have following technical characterictic: described detent is square.

In this utility model, also have following technical characterictic: described collapsible blade bottom mid portion is for semicircle, and this semicircle place is the cut channel mouth of cutting, and is provided with projection near the semicircle lamellar body in collapsible blade bottom.

This utility model compared with prior art has the following advantages and good effect: 1. be provided with collapsible blade on the empennage of syringe, be provided with detent on the fin of pin select, thereby can be used for continuous negative pressure drainage.During drain, because the blade both sides are tear string (also claiming geosutures), and the blade bottom is the otch of not cutting, thereby the blade both sides can be torn and the bottom connection, extract one section pin select out and make syringe form negative pressure, blade is inserted in the detent, thereby the pin select is positioned, the wound place that the drainage tube that the syringe front end connects guides to the patient implements drain, thereby has realized that syringe can be used for the purpose of continuous negative pressure drainage.2. the syringe volume is little, and light weight is easy to carry, according to difference operation or drainage flow, can select the syringe of different sizes, and is convenient and practical.3. syringe is not made and can be out of shape for the duroplasts plastics, syringe can not occur and take place because of the phenomenon that pressurized causes drain liquid to reflux.4. high clinic actual value is arranged, be particularly suited for thyroid operation, women's head-ornaments portion anaplasty, the parotid gland and operation on neck etc.5. utilize the original containing mark of syringe, can accurately calculate drainage flow, for rehabilitation provides foundation.6. the position by the pin select makes vacuum magnitude have adjustability, for treatment has brought convenience.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, in order to make syringe 1 have continuous negative pressure drainage function and effect, on the empennage 2-1 of syringe 2, be provided with collapsible blade 2-2, pin select 3 has four fin 3-1, and a fin 3-1 is provided with 5 detent 3-2 that spacing is arranged therein.

When not using, collapsible blade 2-2 both sides are to link to each other by the tear string 2-2-1 that is interrupted with empennage 2-1, and collapsible blade bottom is to be connected by the cut channel mouth 2-2-3 that does not cut with empennage.

Collapsible blade 2-2 bottom mid portion is semicircle, and this semicircle place is the cut channel mouth of cutting, and is provided with protruding 2-2-2 near the semicircle lamellar body in collapsible blade bottom.

When syringe 1 is used for drain, syringe 2 front ends connect drainage tube and insert in the wound, outside drawn needle select 3, make pin select 3 positions reach suitable negative pressure position, push the collapsible blade 2-2 on the empennage 2-1, make the tear string 2-2-1 fracture of its both sides, blade 2-2 turns over backward, insert it in the detent 3-2 of fin 3-1, thereby syringe 1 can use as drain.

In above-mentioned blade 2-2 switching process, because blade 2-2 bottom mid portion is semicircle, this semicircle place is the cut channel mouth of cutting, thereby make the empennage corresponding site form a half round cut, thereby protruding 2-2-2 is turn in this half round cut, and protruding 2-2-2 enters the positioning action that plays in the half round cut between blade and the detent.

When having charged into drain liquid in the syringe 1 when negative pressure is descended, can continue outside drawn needle select 3, locate to next detent 3-2 place, to keep enough negative pressure.

After syringe 1 is full of drain liquid, can extract drainage tube out, drain liquid is discharged, continue drain to form negative pressure.

The above, it only is preferred embodiment of the present utility model, be not to be the restriction of this utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
