Abstract
The utility model relates to a single needle double path transfusion device, and the outside of the hollow needle head is tightly sleeved with a needle head sleeve, and the front end of the needle head is in cone shape, and the cone-shaped part is provided with small holes. The back end of the needle head is in Y shape respectively connected with a path and b path. The a path is connected with the needle head and communicated with needle head inner hole, and the b path is communicated with the needle head sleeve. The utility model solves the disadvantage that: when one patient needs to be transfused synchronously or use multi medicine in the clinical work, the transfusion path is needed to be rebuilt. The utility model has the advantages that: one needle head can built two different transfusion path, and the two transfusion paths can respectively and synchronously transfuses different liquid to the body to meet requirements of different speed and using multi drugs, which can avoid the interaction of the drugs and can greatly develop the treatment effect of the drugs, thereby reducing the damaging to the patient blood vessel and the pain of the patient.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments.
Background technology
At present, the transfusion device of hospital and hygiene department use is disposable single channel transfusion device.In clinical use, have many deficiencies and limitation: tend to run into patient's needs while infusion or use multiple medicine in clinical position, the medicine that has can add infusion together, and the medicine that has can not be placed on instillation in one bottle of liquid; Or the medicine that has instillation fast, the medicine that has then needs to instil very lentamente, therefore, existing single channel transfusion device often can't be finished, traditional method is to rebulid infusion channel in clinical, and this method is too much to angiolysis, has increased patient's misery.
Summary of the invention
Goal of the invention of the present utility model is to provide syringe needle of a kind of need can set up two passage infusion different liquids simultaneously to reduce the destructive single needle head dual pathways transfusion device to patient's blood vessel.
The technical solution of the utility model is: tightly be with needle sleeve outside hollow needle, the needle sleeve front end is tapered, the needle sleeve front end has aperture, the needle sleeve rear end is the Y type, connect a passage and b passage respectively, the a passage is connected with hollow needle and is connected with the syringe needle endoporus, and the b passage is connected with needle sleeve.
A, b passage join with the filter, speed regulator, the Mo Feishi pipe that are equipped with separately.
The aperture of said needle sleeve front end is around n uniform aperture of circumferencial direction, wherein n 〉=2 near taper position or taper position.
Said needle sleeve is that resilient material is made.
Feature of the present utility model also is Y type fork mouth place, needle sleeve rear end, has one can make prong airtight returning ending valve after syringe needle is transferred in the needle sleeve.
This utility model can be made into disposable single needle head dual pathways transfusion device.
Compared with prior art, the utlity model has following advantage: only need a syringe needle can set up two different infusion channel, two passages can be distinguished the different liquid of infusion in body simultaneously, satisfy the needs of the different speed of speed.In the critical patients' of section office such as first aid ward, Icu, Ccu rescue, drug application is various, and use this utility model can be avoided the interaction between the medicine, influences each other, and can bring into play the curative effect of medicine to greatest extent; Minimizing reduces patient's misery to the destruction of patient's blood vessel; When improving work quality, saved the time, improved efficient, convenient and swift.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
Among the figure, hollow needle 1 outer tight cover is needle sleeve 2; Needle sleeve 2 front ends are tapered, to make things convenient for needle sleeve 2 and 1 while of hollow needle inserting needle in body; The taper position of needle sleeve 2 is evenly equipped with 3～4 apertures 3 around circumferencial direction; Needle sleeve 2 rear ends are the Y type, connect a path 10 and b passage 11 respectively.The a path 10 is connected with syringe needle 1 and is connected with syringe needle 1 endoporus, is the medicinal liquid infusion channel from a passage, and b passage 11 is connected with needle sleeve 2, is the medicinal liquid infusion channel from the b passage.Needle sleeve 2 is made for elastomeric material.End valve 4 once at the prong place of needle sleeve rear end (with a passage junction), in order to after syringe needle is extracted in the syringe needle pipe box, can make the needle sleeve prong airtight.All be connected with the parts such as filter 5, speed regulator 6, Mo Feishi pipe 7 of each self-configuring on a, the b passage.Near the Mo Feishi pipe, be respectively equipped with red green label 8, play watchful effect.9 is needle handle.
During use, connect medicinal liquid on a passage of transfusion device, the b passage after, respectively to a, the aerofluxus of b passage, select patient's one blood vessel, the right hand is held needle handle, becomes 15～30 ° of inserting needles with horizontal line, see that a passage has blood back after, force down the about 0.3cm of inserting needle, see that the b passage crossed blood back, be and puncture successfully.As required, regulate a, b passage speed regulator separately respectively, regulating flow rate of liquid gets final product, the medicinal liquid that can comparatively fast be totally lost is walked a passage generally speaking, after a passage medicinal liquid was totally lost, the syringe needle 1 that will link to each other with a passage was extracted, and only returning, valve 4 makes the prong place of needle sleeve 2 airtight, needle sleeve 2 is put and is stayed in blood vessel, and the transfusion of this moment then is similar to traditional transfusion.
