Abstract
The utility model discloses an intravenous infusion apparatus with an automatic three-way valve, which comprises an infusion tube (1), a pricking needle (2), an air filter (3), a drip regulation switch (4), a Murphy's dropper (5) and a scalp needle (6). The intravenous infusion apparatus has the following characteristics: the upper end of a liquid medicine filter (7) is connected with the automatic three-way valve (8), an upper port (9) of the automatic three-way valve (8) is connected with the lower end of the infusion tube (1), which is inserted in the upper port (9) of the automatic three-way valve (8), one side of the automatic three-way valve (8) is provided with a side port (10), and automatic opening and closing units (11) are respectively arranged in the upper port (9) and the side port (10) of the automatic three-way valve (8). The infusion apparatus can prevent the air and particulate impurities from entering the body of a patient, intravenous push can be carried out without unplugging the plug connector of the scalp needle, and moreover, the infusion apparatus has the advantages of simple operation, hygiene, convenience and safe use.
Description
Technical field
This utility model relates to a kind of improvement of transfusion device, specifically a kind of intravenous transfusion device that has the automatic shutter three-way valve.
Technical background
At present, when hospital carries out infusion treatment to the patient, all be that medicinal liquid in the liquid bottles that hangs on the drip stand is by the tube for transfusion liquid medicine filter of flowing through, by scalp acupuncture input patient vessel.In infusion process if will carry out intravenous injection to the patient time, need pull up the scalp acupuncture that the liquid medicine filter below connects, with the syringe of injection liquid with inject after the scalp acupuncture needle stand is connected, inject and finish, needle stand joint with scalp acupuncture is connected with the joint of liquid medicine filter below again, recovers transfusion state.The existing deficiency of this transfusion device is: because liquid medicine filter is the lower end that is fixed on tube for transfusion, the medicinal liquid of injecting is without liquid medicine filter, can cause the microgranule in the injection liquid to be pushed in the blood vessel, cause transfusion dangerous, the end interface of liquid medicine filter is exposed in the air in pulling out termination process repeatedly simultaneously, cause the end opening of tube for transfusion also to be directly exposed in the air, pollute easily or infect; In addition, this method of injecting, operation is also inconvenient.At present, housing one side at liquid medicine filter that also has has been set up injection and has been injected mouth, and this mouth of injecting must add pipe close or mouthpiece cover, uses not only and takes a lot of trouble, and also forgets easily sometimes and seals, and causes accident.In addition, because when injecting, tube chamber is communicated with auxilliary liquid pipe, and when injecting pressure when excessive, injection liquid can enter in the tube for transfusion, mixes with medicinal liquid in the tube for transfusion, influences and injects quality.
Summary of the invention
The purpose of this utility model is to provide a kind of and need not to pull up the scalp acupuncture connection-peg and can finish intravenous injection, and can avoid in air and the granulometric impurity input patient body, also avoid injection liquid to enter in the tube for transfusion, and a kind of intravenous transfusion device that has the automatic shutter three-way valve of simple to operate, hygienic and convenient, injection safety.
For reaching above purpose, the technical scheme that this utility model adopted is: this a kind of intravenous transfusion device that has the automatic shutter three-way valve, by tube for transfusion, needle for inserting bottle, air filter, drip velocity modulation joint switch, Mo Feishi dropper and scalp acupuncture constitute, connecting needle for inserting bottle on the upper end of tube for transfusion, be provided with the Mo Feishi dropper at the middle part of tube for transfusion and drip velocity modulation joint switch, connect scalp acupuncture in the lower end of tube for transfusion, seat end at scalp acupuncture connects liquid medicine filter, it is characterized in that connecting the automatic shutter three-way valve in the upper end of liquid medicine filter, insert in the last end interface of automatic shutter three-way valve the lower end of tube for transfusion, one side of automatic shutter three-way valve is established side interface, when injection liquid, side interface with inject needle stand and be connected, be respectively equipped with automatic switch device in the last end interface of automatic shutter three-way valve and in the side interface of a side.
This utility model is also implemented by following measure: described automatic switch device, constitute by promoting ring, spring, connecting rod, stator and moving sheet, connecting rod passes the slide opening on the stator, the upper end is fixed on and promotes on the ring, the lower end is fixed on the moving sheet, through hole and the through hole on the stator on the moving sheet are staggered, and spring is wrapped on the connecting rod.
When using this utility model, in end interface on the bottom insertion automatic shutter three-way valve of tube for transfusion, under the promotion of tube for transfusion bottom, moving sheet moves down, medicinal liquid can be infused by through hole on the stator on the automatic switch device and the through hole on the moving sheet, following end interface is connected with liquid medicine filter, when the needs injection liquid, the syringe of injecting medicine is inserted the side interface of automatic shutter three-way valve, promotion ring on the automatic switch device is pressed, the spring compression makes moving sheet separate with stator, can inject then, inject finish after, extract the syringe of injecting medicine, side interface is closed automatically, recovers the normal infusion state.
The beneficial effects of the utility model are: compare with present transfusion device, owing to added the automatic shutter three-way valve in the upper end of liquid medicine filter, have only when tube for transfusion inserts in the last end interface of automatic shutter three-way valve, could infuse, if pull up tube for transfusion, then infusion port is closed automatically; In like manner, when only injecting the syringe inserting side interface of medicine, automatic switch device just is opened, inject, otherwise, then close automatically, simultaneously, if it is excessive to inject pressure, last end interface then is closed, and therefore, not only can avoid in air and the granulometric impurity input patient body, need not to pull up the scalp acupuncture connection-peg and can finish intravenous injection, and simple to operate, hygienic and convenient, safe in utilization.
