Abstract

An anti-skid transfusion system comprises a hose, and a bottle closure puncture device, a dropping funnel, a flow regulator and a male Luer joint connected through the hose, wherein, the male Luer joint is inserted into and connected with a vein transfusion needle, or an intravenous catheter needle or the female Luer joint of a three-way pipe and is nested with a turnbuckle with internal screw-thread; the back end bore diameter of the turnbuckle is less than the outer diameter of the chimb at the middle part of the male Luer joint; the front end of the female Luer joint is provided with external screw-thread matching with the internal screw-thread of the turnbuckle. Due to the screw-thread fastening structure provided on the male and female Luer joints of the transfusion system, when in use, user can push forward the turnbuckle to the external screw-thread at the front end of the female Luer joint and turn the turnbuckle to make the front end of the female Luer joint enter into the turnbuckle and connect with it through spiral connection till the turnbuckle is limited by the chimb at the middle part of the male Luer joint, thereby, the male Luer joint and the female Luer joint are fastened together by the turnbuckle so as to ensure the safety of the transfusion system in various medical transfusion environments and avoid malpractice caused by transfusion system slipping.

Description

Anti-slip transfusion device

Technical field

This utility model relates to a kind of medical Transfusion device, belongs to technical field of medical instruments.

Background technology

At present, the composition of medical Transfusion device generally comprises flexible pipe, by hose connection bottle plug puncture unit, dropping funnel, flow regulator, male female Luer, male female Luer and venoclysis needle or venous detaining needle or tee T with female female Luer be connected.Male female Luer and female female Luer has certain tapering and socket connection is an one.In the common transfusion process, the basic practical requirement of firm degree that male female Luer and female female Luer are pegged graft.But indoor in Intensive Care Therapy, patient continues transfusion for a long time, transfusion device and on hero, female female Luer may in concrete medical care precess process, be subjected to touching, pullling; Medical personnel are in busy operative process in the operating room, also may touch, pull transfusion device and on hero, female female Luer; The child in infusion process, also may touch, pull transfusion device and on hero, female female Luer.More than several situations all easily cause the loosening slippage of connecting portion of female Luer on the transfusion device, increase medical-risk, even cause malpractice.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of safe and reliable anti-slip transfusion device is provided.

The technical scheme that its technical problem that solves this utility model adopts is as follows: a kind of anti-slip transfusion device, form and comprise flexible pipe, by hose connection bottle plug puncture unit, dropping funnel, flow regulator, male female Luer, male female Luer and venoclysis needle or venous detaining needle or tee T with female female Luer insertion be connected, it is characterized in that being with tapped swivel nut on the described male female Luer, aperture, swivel nut rear end is less than the external diameter of male female Luer middle part chimb, and female female Luer front end has and the corresponding external screw thread of swivel nut female thread.

The beneficial effects of the utility model are as follows: at the hero of transfusion device, be provided with screw threads for fastening mechanism on the female female Luer, during use, earlier male female Luer front end is inserted female female Luer, the two is connected as one, to be pushed into before the swivel nut on the male female Luer on the external screw thread of female female Luer front end again, the turn swivel nut makes female female Luer front end enter swivel nut and is connected with the swivel nut spiral, spacing until swivel nut by the chimb at male female Luer middle part, so male female Luer and female female Luer are just tightened together by swivel nut, so long as not reverse rotation swivel nut consciously, just can not become flexible slippage, guarantee the security reliability of transfusion device in the use of various medical transfusion environment, stop the malpractice that causes because of the transfusion device slippage.

Description of drawings

Fig. 1 is the anti-slip transfusion device structural representation of this utility model.

Number in the figure is illustrated as: 1-bottle plug puncture unit, 2-dropping funnel, 3-flow regulator, 4-flexible pipe, the male female Luer of 5-, the male female Luer chimb of 51-, the male female Luer boss of 52-, 6-swivel nut, the female female Luer of 7-, the female female Luer front end of 71-external screw thread, 8-venoclysis needle.

The specific embodiment

With reference to the accompanying drawings and in conjunction with the embodiments this utility model is described in further detail.But this utility model is not limited to given example.

As shown in Figure 1, the composition of the anti-slip transfusion device of this utility model comprises flexible pipe 4, bottle plug puncture unit 1, dropping funnel 2, flow regulator 3, male female Luer 5 by flexible pipe 4 connections, male female Luer 5 and venoclysis needle 8 or venous detaining needle (not drawing among the figure) or tee T (not drawing among the figure) with 7 insertions of female female Luer be connected, be with tapped swivel nut 6 on the male female Luer 5, the aperture, rear end of swivel nut 6 is less than the external diameter of male female Luer 5 middle part chimbs 51, and the front end of female female Luer 7 has and the corresponding external screw thread 71 of the female thread of swivel nut 6.

In order to make swivel nut 6 relative localization on male female Luer, be unlikely to slip away on the flexible pipe at a distance, among the embodiment as shown in Figure 1, further feature is: the rear end of male female Luer 5 has a boss 52, the external diameter of boss 52 is greater than the aperture, rear end of swivel nut 6, to 6 position-limiting actions of swivel nut, thereby bring convenience for the use of transfusion device.

Claims

1, anti-slip transfusion device, form and comprise flexible pipe, by hose connection bottle plug puncture unit, dropping funnel, flow regulator, male female Luer, male female Luer and venoclysis needle or venous detaining needle or tee T with female female Luer insertion be connected, it is characterized in that being with tapped swivel nut on the described male female Luer, aperture, swivel nut rear end is less than the external diameter of male female Luer middle part chimb, and female female Luer front end has and the corresponding external screw thread of swivel nut female thread.

2, anti-slip transfusion device according to claim 1 is characterized in that described male female Luer rear end has a boss, and the boss external diameter is greater than aperture, swivel nut rear end.
