Abstract
The utility model discloses a disposable amniotic cavity puncture needle. According to the disposable amniotic cavity puncture needle, a puncture needle head (1) is directly connected with one port of a Y-type splitter (2) through a hose, the other two ports of the Y-type splitter (2) are connected with a sucking hose (3) and an injecting hose (4) respectively; the other end of the sucking hose (3) and the other end of the injecting hose (4) are provided with a sucking port (5) and an injecting port (6) respectively and correspondingly; the sucking hose (3) and the injecting hose (4) are provided with a clamping valve (7) and a clamping valve (8) respectively. The disposable amniotic cavity puncture needle is simple in structure, easy to operate and capable of being used in a disposable mode, reducing the infection rate of patients and enabling abortion through injection of rivanol to be safer.
Description
Technical field
This utility model relates to a kind of medical apparatus, particularly a kind of utensil for amniocentesis.
Background technology
The miscarriage of amniocentesis injection ethacridine is a kind of Clinics operation of commonly using clinically.This technology has indication more extensive, technology is more ripe, equipment requirements is not high, the advantages such as operational risk is little, be beneficial to the corresponding section office of situation of all-level hospitals and carry out, but due to a variety of causes, lumbar anaesthesia puncture needle is adopted in present operation more, but this kind complicated operation, increase the patient suffering, is unfavorable for the conventional use of medical treatment.
Summary of the invention
The purpose of this utility model is that a kind of disposable amniotic cavity puncture needle will be provided, and it is simple in structure, processing ease, and the patient suffering is little, and disposable use reduces the infected probability of patient, can make the miscarriage of amniocentesis injection ethacridine safer.
The solution of this utility model technology is such: this disposable amniotic cavity puncture needle is comprised of piercing needle, " Y " type splitter, suction hose, injection hose, piercing needle directly joins with an interface of " Y " type splitter by flexible pipe, two other interface of " Y " type splitter is connected with suction hose, injection hose respectively, corresponding suction ports and the injection port of being respectively equipped with of the other end of suction hose, injection hose, be respectively equipped with the card valve on suction hose and injection hose.
The utility model has the advantages that: this disposable amniotic cavity puncture needle is due to the structure that has adopted " Y " type splitter, making drawing liquid observe with injectable drug carries out simultaneously, alleviated the patient suffering, have simultaneously simple in structure, processing ease, disposable use, reduce patient infection's probability, makes to inject ethacridine and miscarry safer.
The accompanying drawing explanation
Fig. 1 is disposable amniotic cavity puncture needle perspective view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
This disposable amniotic cavity puncture needle is comprised of piercing needle 1, " Y " type splitter 2, suction hose 3, injection hose 4, puncture needle 1 directly joins with an interface of " Y " type splitter 2 by flexible pipe, two other interface of " Y " type splitter 2 is connected with suction hose 3, injection hose 4 respectively, corresponding suction ports 5 and the injection port 6 of being respectively equipped with of the other end of suction hose 3, injection hose 4, be respectively equipped with card valve 7,8 on suction hose 3 and injection hose 4.
during use, first the card valve 8 on injection hose 4 cuts out, make it to be in the state of blocking, again by piercing needle 1 inserting needle approximately after 2 centimetres, in suction ports 5, connect 20 milliliters of syringes, after suction, suction hose 3 can be the vacuum shape, continuing inserting needle treats that suction hose 3 is interior and sees that liquid represents that piercing needle 1 enters amniotic cavity, card valve 7 on suction hose 3 cuts out, card valve 8 on injection hose 4 is opened, get in addition 20 milliliters of syringe and extract the ethacridine medicine, by injection port 6, medicine is slowly injected by injection hose 4, after complete, will block valve 8 closes, extract piercing needle 1, complete operation.
