Technical field

This utility model is related to a kind of medical apparatus and instruments, more particularly to one kind can repeatable operation tapping device.

Background technology

Tapping is typically with 50ml syringe connecting puncture needle heads as clinically usual therapeutic modality, After extracting enough liquid, syringe is pulled up, then injected liquid in container, this mode of operation is not only bothered, and instead Multiple syringe of choosing also increase the infection probability of patient, particularly internal injury it is heavier have big quantity of fluid in patient body, therefore Needs are a kind of can be with repeatable operation, the tapping device of efficiency high.

The content of the invention

The purpose of this utility model be to provide one kind can repeatable operation tapping device, can be in the feelings for not extracting liquid extracting device Repeatedly drawing liquid, efficiency high, drawing liquid amount are big under condition.

For achieving the above object, the technical solution adopted in the utility model is：

One kind can repeatable operation tapping device, including push-pull bar, cylinder, piston, needle stand, syringe needle, the front end of push-pull bar Connection piston, push-pull bar is sleeved in cylinder with piston, and the front end of cylinder is provided with needle stand, and syringe needle is arranged on needle stand, its feature It is：Turnover panel chamber is provided with the front end of push-pull bar, piston hole is provided with piston, linked hole, turnover panel chamber difference are provided with the middle of push-pull bar Communicate with piston hole and linked hole, turnover panel is located at turnover panel intracavity, one end of turnover panel is fixedly mounted on the lower surface of piston, turnover panel Can freely rotate around one end, turnover panel near the lower surface of piston when can completely block piston hole, needle stand and syringe needle it Between threeway is installed, threeway is connected by connecting tube with joint, Liquid storage bag be arranged on joint on.

According to it is described can repeatable operation tapping device, it is characterised in that：The threeway is by cross over pipe, waterproof and breathable Film, drain pipe composition, drain pipe angle obliquely is arranged on cross over pipe, and waterproof and breathable is installed in the latter half of cross over pipe Film, waterproof ventilated membrane is located at the lower section of UNICOM's mouth between drain pipe and cross over pipe, liquid can from the entrance suitable for reading of cross over pipe, from Drain pipe flows out, and waterproof ventilated membrane enables to air and passes through, but liquid can not pass through.

The utility model has the advantages of being：When insert the needle into carry out drawing liquid in vivo when, when push-pull bar outward During drawing, the air pressure between piston and cylinder can diminish, and now turnover panel can completely block piston hole, make liquid from syringe needle through pin Seat, threeway enter into connecting tube, and in the presence of waterproof ventilated membrane, liquid can be entered in Liquid storage bag by connecting tube；When pushing away Turnover panel can be rotated down during push-pull bar, and the gas between piston and cylinder can be discharged by piston hole and linked hole, so can be with Repeatable operation is carried out, so as to internal liquid is completely discharged in Liquid storage bag, can be anti-in the case where liquid extracting device is not extracted Multiple drawing liquid, efficiency high, drawing liquid amount are big.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment：

This utility model as Figure 1-3, one kind can repeatable operation tapping device, including push-pull bar 1, cylinder 3, piston 7th, needle stand 8, syringe needle 10, the front end connection piston 7 of push-pull bar 1, push-pull bar 1 is sleeved in cylinder 3 with piston 7, the front end of cylinder 3 Needle stand 8 is provided with, syringe needle 10 is arranged on needle stand 8, it is characterized in that：It is provided with the front end of push-pull bar 1 in turnover panel chamber 4, piston 7 and is provided with Piston hole 6, is provided with linked hole 2 in the middle of push-pull bar 1, turnover panel chamber 4 communicates respectively with piston hole 6 and linked hole 2, and turnover panel 5 is located at and turns over In plate chamber 4, one end of turnover panel 5 is fixedly mounted on the lower surface of piston 7, and turnover panel 5 can freely be rotated around one end, turnover panel 5 Piston hole 6 can be completely blocked during the lower surface of close piston 7, threeway 9 is installed between needle stand 8 and syringe needle 10, threeway 9 passes through Connecting tube 11 is connected with joint 12, and Liquid storage bag 13 is arranged on joint 12.According to it is described can repeatable operation tapping device, It is characterized in that：The threeway 9 is made up of cross over pipe 901, waterproof ventilated membrane 902, drain pipe 903, and drain pipe 903 is obliquely Angle is arranged on cross over pipe 901, and waterproof ventilated membrane 902, waterproof ventilated membrane 902 are installed in the latter half of cross over pipe 901 The lower section of UNICOM's mouth between drain pipe 903 and cross over pipe 901, liquid can be from the entrance suitable for reading of cross over pipe 901, from drain pipe 903 flow out, and waterproof ventilated membrane 902 enables to air and passes through, but liquid can not pass through.

Principle of the present utility model and embodiment are as described below：When syringe needle 10 is inserted into carry out drawing liquid in vivo when, work as handle When push-pull bar 1 pulls outward, the air pressure between piston 7 and cylinder 3 can diminish, and now turnover panel 5 can completely block piston hole 6, make Liquid enters into connecting tube 11 from syringe needle 10 through threeway 9, and in the presence of waterproof ventilated membrane 902, liquid can pass through connecting tube 11 enter in Liquid storage bag 13；When push-pull bar 1 is pushed away, turnover panel 5 can be rotated down, and the gas between piston 7 and cylinder 3 can pass through Piston hole 6 and linked hole 2 are discharged, and can so carry out repeatable operation, so as to internal liquid is completely discharged to Liquid storage bag 13 It is interior, can repeatedly drawing liquid, efficiency high, drawing liquid amount be big in the case where liquid extracting device is not extracted.
