Abstract
The utility model discloses a thoracic puncture needle. The tail end of a needle head is connected with a soft rubber pipe which is connected with a water pumping branch pipe and a drug injection branch pipe; the needle head is provided with a needle base which is provided with two sucking discs; the needle base is tightly sheathed on the needle head and can move back and forth; the outer wall of the needle head is provided with scales; and the needle head is provided with a positioning sleeve which is tightly sheathed on the outer wall of the needle head. The thoracic puncture needle can set the needle-inserting depth when in puncture, thus avoiding the error caused by the original visual observation; and the needle head is fixed on the body of the patient by the needle base, the sucking disc and the like, thus avoiding the occurrence of needle dropping condition.
Description
Technical field
This utility model relates to technical field of medical instruments, is specially a kind of thoracentesis needle.
Background technology
The way treatment of intrathoracic hydrops, pneumatosis generally being adopted thoracentesis is gone up in medical treatment at present.Generally estimate definite depth of needle by the medical worker when present thoracentesis needle uses, inserting needle is crossed and can be punctured alveolar deeply and cause pneumothorax, and the shallow difficult extraction hydrops of inserting needle is difficult to grasp the degree of depth that syringe needle enters torso model.In addition, after syringe needle thrusts human body, do not have the device of fixed needle, make syringe needle break away from patient body easily, to making puncture failure.
The utility model content
For overcoming above-mentioned technical problem, this utility model provides a kind of easy control depth of needle, and the syringe needle place is provided with the thoracentesis needle of fixture.
For realizing above-mentioned technical purpose, this utility model is achieved through the following technical solutions: a kind of thoracentesis needle, the syringe needle tail end connects flexible rubber hose, the flexible rubber hose other end connects threeway, threeway connects draw water arm and injection arm respectively, draw water arm and injection arm top is equipped with plug, it is characterized in that syringe needle is provided with a needle stand, needle stand is provided with two suckers, needle stand tightly is enclosed within on the syringe needle and can moves around, the syringe needle outer wall is provided with scale, is provided with a positioning sleeve in the scale range on syringe needle, and the location is locked and is enclosed within on the outer wall of syringe needle.Scale on the syringe needle shows depth of needle, during use needle stand is fixed on human body puncture place by sucker, regulates positioning sleeve behind the position on the syringe needle, syringe needle punctures in patient's body, when positioning sleeve props up needle stand, reach the purpose degree of depth of puncture, and then can carry out operations such as discharge opeing, injection.
Depth of needle when this utility model can be set puncture, the error of having avoided range estimation in the past to bring, syringe needle is fixed on by needle stand, sucker etc. on one's body the patient, has avoided the generation of run-bake-needle fault situation.
