Abstract

The utility model belongs to the technical field of an infusion apparatus, and particularly relates to a heparin cap. The heparin cap comprises a front end part (1) and a rear end part (2), wherein a rubber plug (3) is formed at the rear end part (2); the front end part (1) is connected with an end cover (4) through a thread; the rear end part (2) is connected with an extension sleeve (5) through the thread; the thread on the front end part (1) is an inner thread; the thread on the rear end part (2) is an outer thread; the extension sleeve (5) is composed of an inner tube and an outer tube sleeved together. By adopting the heparin cap, not only can the probability that the heparin cap slips from fingers of medical personnel be greatly reduced, but also the front end part and the rear end part of the heparin cap can be effectively prevented from being polluted, and the overall volume is increased a little.

Description

A kind of calparine cap

Technical field

This utility model belongs to infusion apparatus technical field, particularly a kind of calparine cap.

Background technology

As shown in Figure 1, totally in a tubular form, total length is 2～3 centimetres to calparine cap structure of the prior art, and there is screw thread the inner side of leading section for being connected with human injection's pin, and rearward end has rubber stopper to insert for the syringe needle of transfusion needle.Fig. 2 shows the sectional structure of calparine cap.Because calparine cap length is shorter, during use, often can, from landing between medical personnel's finger, pollute.The innovation and creation that December in 2012 application number on the 5th is 201220109325.X disclose a kind of disposable use calparine cap, the outside of its shell is provided with anti-skidding lines, inner surface of outer cover is provided with female thread, the outer surface of helmet is provided with the external screw thread that can coordinate with outer casing screw, and one end of plug extends to outside shell.The weak point of this scheme has: (1) helmet is positioned at the leading section of calparine cap, during use, need first the leading section of calparine cap to be connected with human injection's syringe needle, now must first remove helmet, remove after helmet, calparine cap becomes again original short and small apperance again, inconvenient hand-held, be still easy to landing; And for increasing the length of calparine cap, helmet need be processed longlyer, the one end that makes its overall volume increase more (2) plug extends to shell has increased the probability polluting outward on the contrary.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of calparine cap is provided, and it is difficult for from landing between medical personnel's finger.

To achieve these goals, the technical solution of the utility model is as follows: a kind of calparine cap, there is leading section and rearward end, and rearward end has rubber stopper, and described leading section has been threaded connection an end cap, and rearward end has been threaded connection a telescopic.

This utility model is all provided with protective measure at leading section and rearward end, and the end cap of leading section is shorter, can cover leading section.The telescopic of rearward end can extend, and when the outer package of calparine cap is opened, telescopic is not condensed state, and overall volume and calparine cap of the prior art are more or less the same.After calparine cap is split out from outer package, it is hand-held that stretching telescopic facilitates its elongation.Rotating end cap is taken off, then the leading section of calparine cap is connected on human injection's pin, then rotary extension cover taken off, and the syringe needle of transfusion needle is inserted to rubber stopper, completes whole connection procedure.

As improvement, the screw thread on described leading section is female thread, and the screw thread in described rearward end is external screw thread.

In prior art, itself is just provided with female thread the leading section of calparine cap, and this utility model does not separately add screw thread; The screw thread of this utility model rearward end is external screw thread, and convenient processing, does not affect again the position of rubber stopper.

As improvement, described telescopic is nested and is formed by inner and outer tubes.

Telescopic, with reference to the structure of boxed milk suction pipe, is nested and is formed by inner and outer tubes, extending once drawing.

In sum, the utlity model has and process advantage convenient, easy to use, successful, can not only greatly reduce calparine cap from the probability of landing between medical personnel's finger, can also effectively prevent that the leading section of calparine cap and rearward end are contaminated, and overall volume increases little.

The specific embodiment

Embodiment 1

As shown in Fig. 3～5, a kind of calparine cap, has leading section 1 and rearward end 2, and rearward end 2 has rubber stopper 3, and leading section 1 has been threaded connection an end cap 4, and rearward end 2 has been threaded connection a telescopic 5.Screw thread on leading section 1 is female thread, and the screw thread in rearward end 2 is external screw thread.Telescopic 5 is nested and is formed by inner and outer tubes.Fig. 6 shows the state after calparine cap has just been connected with human injection's pin 6.

Claims
