Abstract

The utility model relates to a disposable infusion device used for treating patients, composed of an air inlet pipe, a three-way pipe, a filter, a dripping pipe, a liquid regulating valve, a vein needle head, and a liquid inlet needle head. The utility model is characterized in that the filter is arranged on a hose which is positioned at the middle of the three-way pipe and the dripping pipe. The utility model has the advantages of reasonable structure, convenient operation, safety, favorable effect, no fearing psychology caused by the air in a blood vessel for a patient, and non partial skin pain, gets rid of the stale and brings forth the fresh, and can bring benefits for people.

Description

Disposable infusion device

This utility model relates to the invalid disposable transfusion device of a kind of treatment.

When the treatment various diseases, usually need to carry out venous transfusion to patient, improvement along with the hygiene medical treatment condition, prevent the infection of pathogenic bacteria, extensively adopt disposable transfusion device in transfusion, its advantage is easy to use, has prevented temperature reaction and cross infection that the transfusion of sebific duct type brings, sanitation and hygiene are subjected to patient and medical worker's welcome deeply.But, the present disposable transfusion device that uses, its structure is to thrust the venous joint at transfusion device filter is housed, though can play filtration to liquid, dangerous sometimes, because retain gas in the filter easily, be difficult for discharging, the gas that remains in the filter can have minute bubbles to enter blood flow with liquid with patient body position's conversion (filter is also along with activity) sometimes, brings unfavorable factor to patient treatment; Particularly, easily produce the feared state of mind, directly can influence therapeutic effect, but also can cause the patient to think medical personnel's irresponsibility by mistake understanding that the air admission blood flow has the patient of hazardness, thus influence relation to each other; Moreover, filter is contained in this version in joint, when critical patient's rescue need be changed big syringe needle (directly syringe needle), filter plays leverage, form about 15 ° angle with patient skin, cause patient's local skin to support pain, and be difficult for fixing, and the operation before the transfusion is also cumbersome time-consuming, is unfavorable for the treatment to the patient.

The purpose of this utility model is exactly at the above-mentioned disposable transfusion device unreasonable unfavorable factor of easily bringing in the use structurally, and a kind of improved new disposable transfusion system is provided.

The utility model is achieved like this, utilize present disposable transfusion device, structurally transform, the filter that is about to former disposable transfusion device is positioned on the syringe needle place, change into and be positioned on the Murphy type burette top, the bottom of tee T, the termination that the syringe needle that thrusts vein blood vessel directly assigns into tube for transfusion gets final product, and all the other structures are with existing disposable transfusion device.

This utility model is rational in infrastructure, practical and convenient safety, and favourable patient's treatment also for medical personnel's operation brings convenience, reduces opportunities for contamination.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 inserts the interior state diagram of infusion bottle for this utility model.

By shown in Figure 1; this utility model is by air inlet pipe 1; tee T 2; filter 3; dropper 4; liquid adjusting valve 5; venous needle 6; feed liquor syringe needle 7 constitutes; feed liquor syringe needle 7 is in the termination of infusion tube; be used for when transfusion, inserting infusion bottle 8 (seeing shown in Figure 2); next side at feed liquor syringe needle 7 is equipped with air inlet pipe 1; be used for air inlet in infusion bottle; in bottle, import the human vein smoothly to guarantee liquid through tube for transfusion; tee T 2 is housed on the lower hose of feed liquor syringe needle 7; be used to regulate liquid level and dosing midway; on tee T 2 and the dropper 4 intermediary flexible pipes filter 3 is housed; be used for liquid is carried out filtration, purification; in case little medicine grain or impurity enter in the human vein; produce the reaction of malpractice or medicinal liquid; dropper 4 is to expand body; be used for storaging liquid and observe dripping speed; for the ease of regulating and the control medicinal liquid splashes into speed in the human vein; on the infusion tube of the top of venous needle 6, be set with liquid adjusting valve 5; the infusion tube termination is equipped with venous needle 6; during use, venous needle 6 thrusts in the human vein blood vessel.This utility model material therefor, production technology and using method do not have any specific (special) requirements all with original disposable transfusion device.The change of its structure, for disposable transfusion device has brought new remarkable result:

1. because of filter is positioned on the dropper top, though there is gas to retain, bubble can not enter in the vein blood vessel with liquid, and it is safer to infuse;

2. because of the complete emptying of gas in the infusion tube between dropper and venous needle, can not have in the gas intravasation, thereby eliminate patient's the feared state of mind, can help treatment greatly patient;

3. the transfusion device front end does not have filter, and when changing direct syringe needle, joint and skin almost are planes, and having avoided the local skin of patient that the people is arranged is the pain that causes.

4. because easy to operate, the time is short, has reduced opportunities for contamination, helps patient's rehabilitation.

In a word, this utility model is an innovation to original disposable transfusion device, makes it structure and more becomes rationally, and result of use is better, and it is weeded out the old and bring forth the new, and must be welcome by patient and medical personnel, brings benefit to the mankind.

Claims

A kind of disposable transfusion device is to be made of air inlet pipe, tee T, filter, dropper, liquid adjusting valve, venous needle, feed liquor syringe needle, it is characterized in that it being on tee T (2) and the intermediary flexible pipe of dropper (4) filter (3) to be housed.
