Description

A pleural effusion draw-out device for breathing and endocrinology branch of academic or vocational study

Technical Field

The utility model relates to the field of medical equipment, concretely relates to pleural effusion draw-out device for respiration and endocrinology department.

Background

In respiratory and endocrinological diseases, pleural effusions, such as bacterial infections complicated by respiratory infections or endocrinological diseases, are commonly encountered, leading to the development of pleural effusions, a common clinical sign of pathological fluid accumulation in the pleural cavity.

Pleural effusion can be caused by a variety of diseases, for example, respiratory diseases and endocrine disorders can cause pleural effusion, and clinical manifestations of pleural effusion include a variety of respiratory symptoms, such as chest tightness, chest pain, shortness of breath, palpitation, dyspnea, even sitting up and breathing with cyanosis, which causes pain to the patient.

To the pleural effusion, it often adopts ordinary syringe puncture thorax to extract the pleural effusion clinically, however, adopt current syringe thorax puncture in-process, the syringe needle can't carry out effectual fixed, because the puncture degree of difficulty is big, puncture in-process patient leads to reasons such as the health removes or the muscle shake because of the pain, the puncture direction that leads to puncture in-process syringe needle easily changes, not only increase the puncture and give the misery that patient brought, the puncture direction change of syringe needle causes the puncture risk of syringe needle to organs such as lung and heart easily moreover. In addition, in the puncture process of the existing syringe, the puncture speed is usually determined by the puncture experience of doctors, and for doctors with insufficient experience, the puncture speed is difficult to control, so that the puncture speed is easy to be too high, the puncture depth is usually too large due to the too high puncture speed, and the risk of puncturing organs such as lungs and hearts around pleural effusion by a needle head is further caused. In addition, after the needle head of the puncture needle reaches the pleural effusion, the puncture needle needs to be manually held in the process of sucking the effusion, however, the effusion needs to be sucked for a certain time, and due to the reasons that a patient may cause body movement or muscle shake due to pain, hands shake when the puncture needle is manually held and the like, the puncture needle is easy to move back and forth or the puncture direction is changed in the effusion sucking process, so that the pain of the patient is caused, and the risk of puncturing organs such as lungs, hearts and the like by the needle head is caused. Therefore, the existing puncture method has high operation requirements on medical care operators, is complex in operation, wastes time and labor, increases working difficulty for medical staff, and causes that the medical staff has to puncture again due to the change of the direction of a needle head or the over-high puncture speed, thereby increasing the pain of patients.

(1) communicating an injector nozzle of an extraction injector cylinder with a concave hole on a needle handle of the injection needle, contacting an opening (a pot opening) of a pot body with skin of a puncture part, extracting air from a pot cavity of the pot body through an extraction valve, and changing air pressure in the pot cavity into negative pressure to enable the pot body to be adsorbed on the skin, wherein at the moment, the pot body is adsorbed on the skin, and the puncture direction of a needle head of the injection needle is fixed by a second limiting plate and a first perforation arranged on a sealing plug on the pot body, so that the needle head of the injection needle is kept unchanged in the puncture process, and the risk of puncture of organs such as lung effusion, heart and the like caused by the change of the needle head of the injection needle in the puncture process due to body movement or muscle shake and the like caused by pain of a patient is avoided;

(3) through the push rod with the outside pull of piston, can take out a syringe section of thick bamboo with the pleural effusion, after syringe needle extraction pleural effusion was ended, make the dead lever pass through the screw thread at the downthehole rotation of helicoidal circle once more for "V" type puncture on the dead lever corresponds with "V" type perforation on the first limiting plate, reset spring passes through the reset action, with the syringe needle extraction, then take off the chock plug on the jar body from the pressure release hole, the jar chamber communicates with each other with the atmosphere, take off on one's body from the user with the jar body, accomplish the drawing of liquid process.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
