Abstract
The utility model discloses a multifunction disposable infusion device, relating to a medical appliance inputting mediums into a human body, and mainly composed of a liquid bottle, a Murphy's dropper, an infusion rubber pipe, a regulator, and a scalp needle. The utility model is characterized in that a floating ball which can rise and fall with the inner liquid level of the Murphy's dropper is arranged in the Murphy's dropper; when the floating ball falls to the inner bottom (opening) of the Murphy's dropper, infusion is automatically stopped; a special negative pressure cylinder assembly is arranged at the upper part of the scalp needle of the infusion device, negative pressure can be formed, and the goal of seeing blood with once insertion of the needle can be rapidly realized; an injector matched with the negative pressure cylinder assembly can realize vein medicine pushing.
Description
This utility model relates to medium is input to the intravital apparatus of people, is disposable transfusion device for a kind ofly improving the rate of hitting the nail on the head, being convenient to that vein pushes away medicine, can stop transfusion automatically when looking the dosage transfusion especially.
Venous transfusion and be clinical treatment and rob a kind of important channel and the method for asking the urgent patient by the liquid administration is given severely sick person's liquid make-up, is used medicine, supporting treatment mostly to finish by transfusion.
At present, disposable transfusion device commonly used exposes many defectives in clinical use for many years, as function singleness, poor practicability, manipulate inconvenience.Also there is the people that a transfusion device has been done some improvement, as solve disposable aerofluxus, but up to the present, some vital problems of transfusion device as: form negative pressure, improve the rate of hitting the nail on the head, to be convenient to can stop automatically when vein pushes away medicine and looks the dosage transfusion problem such as transfusion still unresolved.
Transfusion is significant in clinical, has a lot of urgent patients' treatment and rescue to finish by transfusion.The height of the rate of hitting the nail on the head during transfusion is influence and decision therapeutic effect directly, is related to the success or failure of rescue.Can rescue urgent patient's critical moment, time is life, should seize every minute and second, go up liquid and use medicine to patient is defeated, has very important effect.Usually, how the height of the rate of hitting the nail on the head is mainly decided by the height and the clinical performance of nurse's self-technique level, but there is several factors can restrict, limit the utilization and the performance of nurse's technical merit, as influence of patient's severe loss of blood, circulatory failure, Chronic consumptions, infant, adiposis patient individual variation and climate change etc., can cause all that the angioplerosis degree is little, blood pressure is lower than the normal person, influence blood back behind the inserting needle.
Forming negative pressure is the key that improves the rate of hitting the nail on the head.In principle, when the pressure in the transfusion device during greater than the blood in human body in pipe pressure, liquid can flow into blood vessel during transfusion, otherwise then blood flows backwards to the syringe needle of transfusion device, if the two pressure equates then not flow mutually.During with traditional disposable transfusion device puncture vessel, often with operator's experience with feel to carry out, in clinical practice, run into the patient of the difficult puncture of blood vessel, the normal way that adopts of nurse is to connect a syringe at scalp acupuncture sebific duct rear portion, is cooperated by two people and finishes vascular puncture, that is: the first people is thrust syringe needle subcutaneous, second people takes out syringe " plug " backward, makes and forms negative pressure in the scalp acupuncture.The slow inserting needle of first people is sought blood vessel, in case when syringe needle thrust blood vessel, blood was inhaled into scalp acupuncture immediately, flows into (blood back), stop inserting needle immediately in the sebific duct.This method is very effective, but shortcoming is inconvenient, must two people cooperate.Heavy or nurse during on night duty giving emergency treatment to a patient, is difficult to utilization separately when the treatment task.
Vein pushes away medicine: the patient who has clinically is the quiet again medicine that pushes away in transfusion.Traditional transfusion device is that the transfusion device front end separates with the scalp acupuncture rear end, syringe and scalp acupuncture are joined and changes one bottle of liquid, and syringe needle just can blood back, and blood is very fast to be solidified in scalp acupuncture, stops up syringe needle.After changing liquid, have to puncture again, increase patient's misery, and patient is nervous in the transfusion, is difficult to wholwe-hearted rest, has increased the amount of accompanying and attending to.
The purpose of this utility model is to overcome the weak point in the above-mentioned prior art, and a kind of negative pressure that can form is provided, and the rate of improve hitting the nail on the head, is convenient to vein and pushes away medicine, can stop the disposable transfusion device of infusing when looking the dosage transfusion automatically.
Task of the present utility model is finished like this:
This transfusion device is a kind of improvement deisgn product, and it is to have set up negative pressure cylinder (vacuum cylinder) and increased a ball float on existing transfusion device basis in Murphy's burette.
This transfusion device is to make according to forming principle of negative pressure, at piston cylinder of the anterior installation of transfusion device, when scalp acupuncture thrust subcutaneous after, with actuator that piston cylinder near-end sebific duct is stuck, and " plug (piston) " in the piston cylinder one pulled out backward, liquid enters piston cylinder, forms negative pressure (vacuum) in the scalp acupuncture.
This transfusion device is provided with a ball float in Murphy's burette, after liquid entered Murphy's burette, under buoyancy, ball float levitating and Murphy's burette lower end disengaged, liquid enters scalp acupuncture from the Murphy's burette lower end via sebific duct, and whole transfusion work can be carried out.In the infusion process, ball float falls with the intraluminal fluid face, the lower end that ball float drops to pipe just can close the following outlet of pipe, so just, stop in the bottom sebific duct of air admission pipe, this moment, Murphy's burette will rest in the sebific duct with the liquid of lower part, and can not continue to splash into blood vessel, thereby realize stopping the purpose of transfusion.
This utility model further specifies middle in conjunction with the accompanying drawings embodiment:
Fig. 1 is the general layout structure diagram of multifunctional disposable transfusion device,
Fig. 2 is a Murphy's burette assembly structure sketch in this transfusion device,
Fig. 3 is a negative pressure cylinder assembly structure sketch in this transfusion device,
The structure diagram that Fig. 4 is used for negative pressure cylinder assembly in this transfusion device and syringe.
The sequence number at parts and position thereof explanation in the diagram:
1, be provided with the scalp acupuncture of needle handle, 2, the scalp acupuncture latex tubing, 3, the scalp needle stand, 4, the negative pressure cylinder assembly, 5, the transfusion device sebific duct, 6, actuator, 7, the transfusion device sebific duct, 8, the Murphy's burette assembly, 9, the transfusion device sebific duct, 10, gas inlet rubber tube, 11, infusion bottle, 12, liquid, 8-1, ball float groove (position) in the Murphy's burette, 8-2, liquid, 8-3, ball float, 8-4, the Murphy's burette shell, 4-1, piston cap, 4-2, the negative pressure cylinder shell, 4-3, piston (plug), 4-4, syringe piston, 4-5, injector syringe, 4-6, syringe (syringe) nipple.
