A kind of perforator that is used for antidrip empty transfusion device
Technical field
This utility model relates to the perforator on a kind of transfusion device, is specifically related to a kind of perforator that is used for antidrip empty transfusion device.
Background technology
Medical and nursing work person often is under the various pressure states, and their work is exactly a large amount of transfusion of preparation, infusion, monitoring and replacing, but their target is exactly these work any mistake of can not trying one's best, and gives the nursing with patient's hommization.
The present perforator that is used for transfusion device scarcely possesses the function of antidrip sky.When medicinal liquid instils when will use up, as guard untimely, just may cause medicinal liquid in the transfusion device to flow to end after, make in the air admission human vein pipe, cause the serious consequence of gas embolism in the human vein pipe, thereby cause malpractice.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of perforator that is used for antidrip empty transfusion device to be provided, and it can effectively stop in air admission tube for transfusion and the patient body, prevents because of the defeated malpractice that causes to the greatest extent of medicinal liquid.
The technical scheme that realizes above-mentioned purpose is: a kind of perforator that is used for antidrip empty transfusion device, comprise puncture needle, blow vent and liquid dripping kettle, and wherein, the inner chamber bottom surface of described liquid dripping kettle is provided with one deck air diaphragms, and the material of this air diaphragms is Φ 15 polysulfone membrane.
The above-mentioned perforator that is used for antidrip empty transfusion device, wherein, described liquid dripping kettle is the two-part structure, be it by the first half, Lower Half and be connected the first half and Lower Half between the center collar and constitute the cavity body of a capsule shape, and its first half and Lower Half adopt rigid transparent material and soft transparent material to make respectively.
The above-mentioned perforator that is used for antidrip empty transfusion device, wherein, the first half of described liquid dripping kettle adopts Merlon to make, and the Lower Half of described liquid dripping kettle adopts soft polypropylene to make.
The technical scheme that is used for the perforator of antidrip empty transfusion device of the present utility model, the intracavity bottom of the liquid dripping kettle of employing in perforator is provided with the air diaphragms of one deck as a barrier, when fluid drips is empty, this air diaphragms can make liquid level stop at the bottom of liquid dripping kettle, it is the upper surface of air diaphragms, effectively stoped in air admission tube for transfusion and the patient body, reached and prevented the purpose that gas in the human vein pipe is fastened plug, thereby guaranteed the safety of patient in infusion process, prevented because of the defeated malpractice that causes to the greatest extent of medicinal liquid.
Description of drawings
Fig. 1 is the structural representation that is used for the perforator of antidrip empty transfusion device of the present utility model;
The specific embodiment
In order to understand the technical solution of the utility model better, also be described in detail in conjunction with the accompanying drawings below by specific embodiment:
See also Fig. 1, the perforator that is used for antidrip empty transfusion device of the present utility model comprises puncture needle 1, blow vent 2 and liquid dripping kettle 3.Wherein:
The air intake of puncture needle 1 is located at different horizontal planes with liquid outlet, can reduce the liquid waste;
Be provided with the air filter that stops antibacterial to pass through in the blow vent 2, when using glass infusion bottle, need open, with the compensation negative pressure;
The inner chamber bottom surface of liquid dripping kettle 3 is provided with one deck air diaphragms 30, and the material of this air diaphragms 30 is Φ 15 polysulfone membrane.When fluid drips is empty, this air diaphragms 30 can make liquid level stop at the bottom of liquid dripping kettle 3, it is the upper surface of air diaphragms 30, thereby effectively stoped in air admission tube for transfusion and the patient body, reached and prevented the purpose that gas in the human vein pipe is fastened plug, thereby guaranteed the safety of patient in infusion process, prevented because of the defeated malpractice that causes to the greatest extent of medicinal liquid.
In an illustrated embodiments, liquid dripping kettle 3 adopts the two-part structures, and promptly it is made of the first half 31, the center collar 32 and Lower Half 33, and the center collar 32 is used for the first half 31 and Lower Half 33 linked together and forms the cavity body of a capsule shape;
The first half 31 of liquid dripping kettle 3 adopts rigid transparent material, and this material preferably adopts Merlon (PC material); The Lower Half 33 of liquid dripping kettle 3 adopts soft transparent material to make, and this material preferably adopts soft polypropylene (PP material).
The liquid dripping kettle that full impregnated is bright can conveniently be observed and drip speed, and the first half adopts hard material conveniently to puncture; Lower Half adopts flexible material conveniently to push so that enter liquid dripping kettle in medicinal liquid arrive required liquid level.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating this utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
