Abstract
The utility model discloses a kind of syringe and three-way valve is connected and fixed device.It comprises L-type body, U-shaped opening and double hook, the angled end portion of L-type body head is provided with U-shaped opening, projection is provided with inside U-shaped open end, L-type body afterbody is provided with double hook, the screw boss of the seam of U-shaped opening and three-way valve fits tightly, the rear part edge phase clasp joint of double hook and syringe piston cylinder.This utility model can overcome when pharmacy, and rocking in syringe when the pressure of liquid medicine and push-and-pull syringe piston, syringe can not get loose with three-way valve, thus well solves prior art Problems existing.
Description
Technical field
This utility model relates to technical field of medical instrument, is specifically related to a kind of syringe and three-way valve is connected and fixed device.
Background technology
Fig. 1 is syringe and three-way valve state when working.Syringe is directly inserted on three-way valve, relies on the male cone (strobilus masculinus) of nipple of syringe and the inner conical surface frictional force of three-way valve to fix.When pharmacy, need reciprocating sliding syringe piston, liquid medicine pressure now in syringe is larger, rock when adding push-and-pull syringe piston, cause syringe to get loose from three-way valve, the liquid medicine ejection in syringe, makes medicine cause significant wastage, also cause environmental pollution to bring danger to clinical manipulation, cause doctor's psychentonia and operation inconvenience.
Summary of the invention
Because the above-mentioned defect of prior art, this utility model provides syringe and three-way valve to be connected and fixed device, can overcome when pharmacy, rocking in syringe when the pressure of liquid medicine and push-and-pull syringe piston, syringe can not get loose with three-way valve, thus well solves prior art Problems existing.
For achieving the above object, this utility model provides syringe and three-way valve is connected and fixed device, comprise L-type body, U-shaped opening and double hook, the angled end portion of L-type body head is provided with U-shaped opening, projection is provided with inside U-shaped open end, L-type body afterbody is provided with double hook, and the screw boss of the seam of U-shaped opening and three-way valve fits tightly, the rear part edge phase clasp joint of double hook and syringe piston cylinder.
As preferably, described L-type body is elastic stainless steel body.
As preferably, the length B of described L-type body is 71-105mm, and thickness is 0.8mm.
The beneficial effects of the utility model: can overcome when pharmacy, rocking in syringe when the pressure of liquid medicine and push-and-pull syringe piston, syringe can not get loose with three-way valve, thus well solves prior art Problems existing.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is the connection diagram of syringe and three-way valve;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the side view of Fig. 2;
Fig. 4 scheme of installation of the present utility model.
Detailed description of the invention
With reference to Fig. 2-4, this detailed description of the invention is by the following technical solutions: syringe and three-way valve are connected and fixed device, comprise L-type body 1, U-shaped opening 2 and double hook 3, the angled end portion of L-type body 1 head is provided with U-shaped opening 2, U-shaped opening 2 tip inside is provided with protruding 4, L-type body 1 afterbody is provided with double hook 3, and U-shaped opening 2 fits tightly with the screw boss of the seam of three-way valve, the rear part edge phase clasp joint of double hook 3 and syringe piston cylinder.
It should be noted that described L-type body 1 is elastic stainless steel body.
In addition, the length B of described L-type body 1 is 71-105mm, and thickness is 0.8mm, wide 12mm.
This detailed description of the invention utilizes the interface exterior threaded bosses of three-way valve as a fixing point, and the edge at recycling syringe piston cylinder rear portion is as another fixing point.Again according to diameter and the length of different capabilities syringe, Design and Machining goes out (three for a set of) holder of different size.
The specification of syringe of this detailed description of the invention is as shown in table 1:
Table 1
| Specification of syringe | A | B | C | D |
| 20ML | 98mm | 105mm | 26mm | 20mm |
| 10ML | 85mm | 92mm | 15mm | 9mm |
| 5ML | 65mm | 71mm | 12mm | 7mm |
This detailed description of the invention holder head is designed to U-shaped opening, is easy for installation and removal, and fits tightly with the screw boss of the seam of three-way valve, and U-shaped opening part is designed with projection, and fixation not easily gets loose.Holder afterbody is designed to double hook shape, can stablize the rear part edge hooking syringe piston cylinder, difficult drop-off.Holder is stainless steel, and design l-shaped, has certain elasticity, can make up the size difference after syringe and three-way valve grafting, and after making grafting, syringe and three-way valve have certain clamping force.Can overcome like this when pharmacy, rocking in syringe when the pressure of liquid medicine and push-and-pull syringe piston, syringe can not get loose with three-way valve, thus well solves this problem.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
