Abstract

The utility model relates to a disposable automatic liquid shut-off infusion set. The disposable automatic liquid shut-off infusion set comprises a puncture device, a dripping hopper, a floating valve, an inner sheath, a liquid shut-off piece, a lower end of the dripping hopper and a base, and is characterized in that a group of automatic liquid shut-off mechanism which can effectively prevent blood of a clinical patient from flowing back into an infusion guide tube when an infusion bottle is changed or/and infusion is almost completed, and the automatic liquid shut-off mechanism comprises the floating valve, the inner sheath, the liquid shut-off piece, the lower end of the dripping hopper, which is used as a liquid medicine inlet channel and the base. When the infusion bottle is changed or/and the infusion is completed, the floating valve can descend to a boss of the base along with the liquid level of liquid medicine, and an inner hole of the boss of the base can be blocked through the liquid shut-off piece mounted at the bottom of the floating valve for preventing air from entering into the disposable automatic liquid shut-off infusion set, so that automatic liquid shut-off and prevention of blood return can be further realized.

Description

The automatic solution stopping transfusion device of disposable use

One, technical field

This utility model belongs in a kind of medicine and hygiene fields the infusion set of using when carrying out venous transfusion to clinical patients; Specifically relate to a kind ofly when venous transfusion, can seal liquid-transport pipe-line automatically; The finish backflow of blood of clinical patients of preventing to infuse feeds back fluid catheter and causes patient panic, avoids the automatic solution stopping transfusion device of disposable use of thrombosed danger simultaneously.

Two, background technology

At present, when hospital carries out venous transfusion to clinical patients, generally use disposable transfusion device, like this, played useful effect preventing the cross infection between the patient.Yet; Use this disposable transfusion device also to exist weak point; Be that current disposable transfusion device does not have automatic sealing process when the transposing infusion bottle finishes with transfusion; In case the nursing staff does not notice a little at this moment or inadvertent that the backflow of blood of clinical patients feeds back fluid catheter and causes patient panic, simultaneously thrombosed dangerous meeting brings the factor that is absolutely unsafe to clinical patients and causes malpractice easily and be unfavorable for the treatment to clinical patients; Also gave originally and brought more nervous work, be unfavorable for the nursing of nursing staff conversely again clinical patients with regard to nursing staff with big workload.

Three, utility model content

The purpose of this utility model be to provide a kind of transposing during infusion bottle or/and transfusion can self-enclosed liquid-transport pipe-line when nearly finishing; Feeding back fluid catheter with the backflow of blood that prevents clinical patients causes patient panic; Avoid the automatic solution stopping transfusion device of disposable use of thrombosed danger simultaneously, to reach the usefulness of vein safe infusion.

The purpose of this utility model is achieved in that this utility model includes perforator, dropping funnel, float valve, inner sheath, solution stopping sheet, dropping funnel lower end and the base that connects in regular turn; It is characterized in that: in said dropping funnel, be provided with one group can prevent effectively transposing during infusion bottle or/and transfusion when nearly finishing the backflow of blood of clinical patients feed back the automatic solution stopping mechanism of fluid catheter, said automatic solution stopping mechanism is by float valve, inner sheath, solution stopping sheet, constitute as the dropping funnel lower end and the base of medicinal liquid access road.

This utility model need not clinical patients and the nursing staff be careful venous transfusion often closely and whether finish; When venous transfusion finishes; The automatic solution stopping transfusion device of disposable use can seal liquid-transport pipe-line automatically by means of the float valve in the automatic solution stopping mechanism; Thereby the backflow of blood that prevents clinical patients effectively feeds back fluid catheter, helps the treatment to clinical patients, and this is for the very positive meaning that has of further minimizing malpractice.

Four, description of drawings

Fig. 1, be the structural representation that proposes according to this utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing and embodiment the structure of this utility model is further described:

Labelling among the figure: 1, perforator; 2, dropping funnel; 3, float valve; 4, inner sheath; 5, solution stopping sheet; 6, base.

In the drawings; This utility model includes perforator 1, dropping funnel 2, float valve 3, inner sheath 4, solution stopping sheet 5, dropping funnel 2 lower ends and the base 6 that connects in regular turn; It is characterized in that: in said dropping funnel 2, be provided with one group can prevent effectively transposing during infusion bottle or/and transfusion when nearly finishing the backflow of blood of clinical patients feed back the automatic solution stopping mechanism of fluid catheter, said automatic solution stopping mechanism is by float valve 3, inner sheath 4, solution stopping sheet 5, constitute as dropping funnel 2 lower ends and the base 6 of medicinal liquid access road.

The operation principle of this utility model is: the automatic solution stopping transfusion device of disposable use is in the process of venous transfusion; Automatically the float valve 3 in the solution stopping mechanism can not stop up dropping funnel 2 by means of medicinal liquid buoyancy come-up; Change bottle or/and transfusion when finishing in transfusion, float valve 3 utilizes the solution stopping sheet 5 that is installed in float valve 3 bottoms the interior hole plug of base 6 boss along with the medicinal liquid liquid level drops to dropping funnel 2 lower ends; Stop air admission, thereby realized automatic solution stopping blood return prevention.

Above mentioned float valve 3 process by plastics flexible glue or silica gel or latex material.

Above-described only is the preferential embodiment of this utility model.Should be pointed out that to those skilled in the art under the prerequisite that does not break away from this utility model principle, can also make some modification and improvement, this also is regarded as belonging to the protection domain of this utility model.

Claims

1. automatic solution stopping transfusion device of disposable use; Include the perforator (1), dropping funnel (2), float valve (3), inner sheath (4), solution stopping sheet (5), dropping funnel (2) lower end and the base (6) that connect in regular turn; It is characterized in that: in said dropping funnel (2), be provided with one group of automatic solution stopping mechanism, said automatic solution stopping mechanism is made up of float valve (3), inner sheath (4), solution stopping sheet (5), dropping funnel (2) lower end and base (6).

2. the automatic solution stopping transfusion device of disposable use according to claim 1 is characterized in that: said float valve (3) is processed by plastics flexible glue or silica gel or latex material.
