Abstract

The utility model discloses an anti-falling device for an intravenous catheter, and belongs to medical infusion instrument accessories. A first semi-jacket and a second-semi-jacket are respectively formed on the two sides of a central line of the lower part of a folding plate and are buckled with each other to form a hollow cylindrical cavity, the tops of the first semi-jacket and the second-semi-jacket are correspondingly combined with each other to form a circular hole-type top notch, the bottoms of the first semi-jacket and the second-semi-jacket are correspondingly combined with each other to form a circular hole-type bottom notch, and a strip-type insertion hole is formed on the central line of the upper part of the folding plate. The anti-falling device is formed by integral injection molding, so that a single-wing handle and a heparin cap which are integrally formed with a scalp needle are contained and limited in the anti-falling device together, the heparin cap and the scalp needle which is punctured into the heparin cap cannot be separated from each other to fall due to traction, and the infusion process safety is ensured.

Description

The venous detaining needle anti-drop device

Technical field

This utility model relates to the adnexa of medical infusion apparatus, specifically a kind of venous detaining needle anti-drop device.

Background technology

Venous detaining needle is one of main utensil of clinical transfusion treatment.Use venous detaining needle to carry out venipuncture with regard to not needing every day, can alleviate the painful and frightened of patient's repeated localised puncture, also be conducive to protection and the first aid of blood vessel, alleviated simultaneously nursing staff's work load.Threeway pedestal one end of venous detaining needle is flexible indwelling tube, the pedestal other end is provided with silica gel plug, have the flank handle the rigidity puncture needle, thrust silica gel plug in the pedestal, penetrate and outstanding concentric flexible indwelling tube, pedestal one side connects flexible conduit, and the other end of flexible conduit is the interface that is connected with adapter or calparine cap.

Calparine cap is and the matching used parts of venous detaining needle, can be repeatedly, repeated localised puncture is for transfusion, and injectable drug uses.The calparine cap side-looking is the hollow-core construction of truncated cone, and an end forms the standard lock joint, can spin with the interface of venous detaining needle, and it is stifled that silica gel is set in the other end, uses the service life that the calparine cap tube sealing can prolong venous detaining needle, reduces patient's medical expense.

When venous detaining needle used, the flexible indwelling tube that is combined with the rigidity puncture needle thrust vein blood vessel, and pull out the rigidity puncture needle and keep somewhere flexible indwelling tube, visible vein blood back, interface and the calparine cap of the indwelling needle catheter other end spin, and carry out tube sealing; To connect in addition the silica gel that scalp acupuncture in the infusion set thrusts the calparine cap other end and block up, treat that the medicinal liquid of infusion enters vein blood vessel through scalp acupuncture, calparine cap, remaining needle.

But, in the medicinal liquid infusion process, very thin scalp acupuncture thrust the silica gel of the calparine cap other end stifled after, the slightly careless external force tractive that is subjected to, the syringe needle that scalp acupuncture very easily occurs separates situation about coming off with calparine cap, cause transfusion to be interrupted.

The utility model content

This utility model is exactly in order to solve in the prior art, the segregative problem of the syringe needle of scalp acupuncture and calparine cap in the infusion process, and a kind of venous detaining needle anti-drop device is provided.

This utility model is realized by following technical scheme.

A kind of venous detaining needle anti-drop device, it is formed with respectively the first half sheaths and the second half sheaths that clamping is combined into cylinder cavity to flap lower central line both sides, the first half sheaths and the second half sheath tip correspondences are combined into the inverted draw cut mouth of circular hole, the corresponding kerve mouth that is combined into circular hole in bottom is to being formed with the bar shaped jack on the flap central upper portion line.

This utility model that designs like this, because it is integrated injection molding, therefore, scalp acupuncture and single-blade handle thereof and calparine cap are accommodated, are limited in this utility model inside together, calparine cap and the scalp acupuncture that thrusts in the calparine cap can tractive is separated not come off because being subjected to, and guarantee the safety of infusion process.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is described in detail.

A kind of venous detaining needle anti-drop device, it is formed with respectively the first half sheath 2a and the second half sheath 2b that clamping is combined into cylinder cavity to flap 1 lower central line both sides, clamping in conjunction with after cylinder cavity for holding calparine cap (not shown).The first half sheath 2a and the second half sheath 2b top correspondences are combined into the inverted draw cut mouth 3a of circular hole, and the bottom correspondence is combined into the kerve mouth 3b of circular hole.

To being formed with bar shaped jack 4 on the flap 1 central upper portion line, bar shaped jack 4 is for inserting with the conjuncted single-blade handle 9 of scalp acupuncture 8.

Described venous detaining needle anti-drop device, its inverted draw cut mouth 3a radius is greater than kerve mouth 3b radius.The circular hole of the first half sheath 2a and the second half corresponding combinations of sheath 2b top inverted draw cut mouth 3a passes for the interface 11 of indwelling needle catheter 10 other ends, is convenient to lock-on connection (not shown) combination with calparine cap; The circular hole of the corresponding combination of the kerve mouth 3b of bottom passes through for thrusting the stifled scalp acupuncture 8 of calparine cap other end silica gel.

Another side of the first half sheath 2a that described venous detaining needle anti-drop device, its clamping are combined into cylinder cavity forms the first board 6a with combined hole 5, the second half corresponding the second board 6b with card projection 7 that form of another side of sheath 2b.

This utility model total length 40mm, the radius 5mm of the first half sheath 2a and the second half sheath 2b, inverted draw cut mouth 3a radius 3mm, kerve mouth 3b radius 1mm.

Described venous detaining needle anti-drop device, this anti-drop device are to adopt the medical non-toxic plastic injection moulding integrated molding.

This utility model of design in use like this, calparine cap be accommodated in the first half sheath 2a and the second half sheath 2b in conjunction with after cylinder cavity in, and with scalp acupuncture 8 disjunctors single-blade handle 9 insert in the bar shaped jacks 4, card projection 7 clampings of combined hole 5 on the first board 6a on the second board 6b are combined, because this utility model is integrated injection molding, therefore, single-blade handle 9 and calparine cap with scalp acupuncture 8 disjunctors are accommodated, be limited in this utility model inside, calparine cap and the scalp acupuncture 8 that thrusts in the calparine cap can tractive is separated not come off because being subjected to, and guarantee the safety of infusion process.
