Abstract
The utility model relates to a disposable needleless Heparin cap which comprises a 6% Ruhr locking type external taper joint, and a filler opening for axially penetrating the entire 6% Ruhr locking type external taper joint is arranged in the 6% Ruhr locking type external taper joint; a drug-adding connector, a sealing rubber plug and a spring are also included, wherein a hollow ladder-shaped hole is arranged in the drug-adding connector, and the drug-adding connector is in threaded connection with the 6% Ruhr locking type external taper joint; the sealing rubber plug and the spring are installed in the ladder-shaped hole of the drug-adding connector, one end of the spring is propped against the main body of the 6% Ruhr locking type external taper joint, and the other end of the spring is propped against the sealing rubber plug so as to cause one end of the ladder-shaped hole to be sealed. The Heparin cap is changed into the needleless Heparin cap, and the structure is improved, so that the risk of puncture wound from the needle is avoided, and the pollution of the needle tube to the liquid medicine is reduced.
Description
Technical field
This utility model relates to medical treatment and goes up the calparine cap that uses, particularly disposable use needleless calparine cap.
Background technology
Continuous development along with science and technology, people's living standard is also improving, and medical level is also constantly improving and progress, and various high-tech electronic equipment also are full of in people's life, yet some armarium apparatus of hospital is still waiting to improve, and it is concerning that people's is healthy.The safety of medical apparatus and instruments and reliability are that people relatively pay close attention to always, the unfortunate forfeiture because hospital does not have corresponding advanced armarium sometimes of patient's life.The research and development department that hospital is relevant is being devoted to the research of technique and the performance improvement of some armarium always in fact.For example the usual unfractionated heparin medicated cap that uses of hospital is owing to there is hidden danger in unreasonable structure, the unfractionated heparin medicated cap generally all has needle tubing, in use, medical personnel need use the infusion apparatus puncture plug of band pin, may cause pricking wound, and the risk of needle tubing to liquid medicine contamination introduced in the use of needle tubing again.
The utility model content
Technical problem to be solved in the utility model is, a kind of disposable use needleless calparine cap is provided, and avoids the pricking wound risk and reduces the pollution of needle tubing to medicinal liquid.
In order to address the above problem the technical solution of the utility model is such:
Disposable use needleless calparine cap, it comprises:
6% Luer lock fixed pattern external taper joint has a filler port that axially runs through whole 6% Luer lock fixed pattern external taper joint in this 6% Luer lock fixed pattern external taper joint;
Dosing connector has the stepped hole of a hollow in the described dosing connector, described dosing connector is connected with described 6% Luer lock fixed pattern external taper joint screw thread;
An one sealing plug and a spring, sealing plug and spring are installed in the stepped hole of described dosing connector, one end of described spring props up described 6% Luer lock fixed pattern external taper joint body, and the other end withstands the sealing plug, to seal up an end of described stepped hole.
Spring of the present utility model adopts taper spring, and a wherein large diameter end props up described bottle stopper puncture needle body, and an end of minor diameter withstands described sealing plug.Adopt taper spring, can apply a higher power, thereby guarantee that the sealing plug can seal up dosing connector well to the sealing plug.
This utility model dosing connector is provided with the locked groove that is connected with the infusion apparatus that has the external taper joint, and infusion apparatus can be connected with dosing connector stabilized seal ground.
The infusion apparatus that this utility model and syringe or other have the external taper joint use that matches so that the medicine in the infusion apparatus is introduced calparine cap, makes things convenient for dosing; Concrete grammar is: described needleless calparine cap allows directly to adopt syringe or other to have the infusion apparatus of external taper joint, inserts or screw-in locking-type nipple, and spring is pushed away downwards, and the cork position descends, and heparin or other liquid can normally be imported; After liquid was totally lost, after pulling out infusion apparatus and leaving the locking-type nipple, spring was upspring automatically, rise on the cork position and restore, and with the sealing of needleless calparine cap, no liquid is leaked.
The beneficial effects of the utility model are, calparine cap becomes the needleless calparine cap, and structure improves, and have so just avoided the pricking wound risk and have reduced the pollution of needle tubing to medicinal liquid.
Description of drawings
Describe this utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of the disposable use needleless of this utility model calparine cap;
Fig. 2 is the cutaway view of the disposable use needleless of this utility model calparine cap.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth this utility model.
Referring to Fig. 1, Fig. 2, disposable use needleless calparine cap, it comprises 6% Luer lock fixed pattern external taper joint 1, dosing connector 2, sealing plug 3, spring 4.Has a filler port 11 that axially runs through whole 6% Luer lock fixed pattern external taper joint 1 in the 6% Luer lock fixed pattern external taper joint 1.Dosing connector 2 is threaded with 6% Luer lock fixed pattern external taper joint 1.
The stepped hole that has a hollow in the dosing connector 2, this stepped hole comprises first hole 21 and second a slightly little hole 22 of diameter that diameter is big slightly, free end in first hole 21 is provided with female thread, so that be threaded with 6% Luer lock fixed pattern external taper joint 1.Dosing connector 2 is provided with the locked groove 23 that is connected with the infusion apparatus that has the external taper joint, and infusion apparatus can be connected with dosing connector 2 stabilized seal ground.This locked groove 23 can be slot or spin slot.Sealing plug 3 is inserted into second hole 22 from first hole, 21 sides, forms the sealing to dosing connector 2; Spring 4 is installed in first hole 21, and an end of spring 4 props up 6% Luer lock fixed pattern external taper joint 1, and the other end withstands sealing plug 3, to seal up dosing connector 2.
Spring 4 adopts taper spring, and a wherein large diameter end props up bottle stopper puncture needle 1 body, and an end of minor diameter withstands sealing plug 3.Adopt taper spring, can apply a higher power, thereby guarantee that the sealing plug can seal dosing connector 2 well to the sealing plug.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in the foregoing description and the description just illustrates principle of the present utility model; this utility model also has various changes and modifications under the prerequisite that does not break away from this utility model spirit and scope, and these changes and improvements all fall in claimed this utility model scope.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
