Pleural cavity puncturing device having function of sucking liquid at uniform speed, for department of respiration

Abstract

The invention discloses a pleural cavity puncturing device having a function of sucking liquid at a uniform speed, for department of respiration. The pleural cavity puncturing device having a functionof sucking liquid at a uniform speed, for department of respiration comprises a base, a liquid sucking puncturing unit and a driving unit, wherein a protrusion platform is integrally arranged on oneside of the upper part of the base; the liquid sucking puncturing unit is mounted at the upper part of the protrusion platform; the driving unit is mounted at the upper part of the base; and the driving unit is in transmission connection with the liquid sucking puncturing unit. Through the adoption of the pleural cavity puncturing device having a function of sucking liquid at a uniform speed, fordepartment of respiration disclosed by the invention, hydrops in the pleural cavity of a patient can be sucked at the uniform speed, so that the situation that when some nurses or doctors which are insufficient in experience suck the hydrops, the speed is too high or too low, and the puncturing effect is influenced can be effectively avoided, the situation that the nurses or the doctors can suck the hydrops in the pleural cavity of the patient at a uniform speed can be guaranteed, and the working strength of the nurses or the doctors can also be effectively reduced; and a protection layer is arranged, so that the functions of anticorrosion, antisepsis, skid resistance and aging resistance of the base are effectively improved, more importantly, the situation that a large quantity of bacteria are bred on the surface of the base can be avoided, and the hygienic condition is good.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, to a thoracentesis device with the function of pumping liquid at a uniform speed in the Department of Respiratory Medicine. Background technique [0002] Puncture and aspiration is a commonly used clinical treatment method. Usually, a 50ml syringe is used to connect the puncture needle. After drawing enough liquid, the syringe is pulled out, and then the liquid is injected into the container. It increases the infection probability of the patient, and at the same time, due to the lack of experience of nurses or doctors, it is impossible to achieve uniform pumping during extraction, which greatly affects the effect of thoracentesis. For this reason, the existing application number is CN201720953411.1 The Chinese patent discloses a thoracentesis device with the function of pumping liquid at a uniform speed in the Department of Respiratory Medicine. It is designed to ad...

[0002] Puncture and aspiration is a commonly used clinical treatment method. Usually, a 50ml syringe is used to connect the puncture needle. After drawing enough liquid, the syringe is pulled out, and then the liquid is injected into the container. It increases the infection probability of the patient, and at the same time, due to the lack of experience of nurses or doctors, it is impossible to achieve uniform pumping during extraction, which greatly affects the effect of thoracentesis. For this reason, the existing application number is CN201720953411.1 The Chinese patent discloses a thoracentesis device with the function of pumping liquid at a uniform speed in the Department of Respiratory Medicine. It is designed to address the above problems, but it still has the following problems in actual use:

[0003] 1) It is recorded in the manual that a speed regulator is installed on the syringe. Since there is an air hole on the speed regulator, when the fluid is extracted, the air inside the syringe will be discharged through the air hole. Since the size of the air hole is fixed, it will be discharged through the air hole within the same time period. The amount of gas is fixed, and the speed of gas discharge is constant to achieve uniform pumping, so as to avoid some inexperienced nurses or doctors who are too fast or too slow to affect the puncture effect when pumping effusions. The pore size of the syringe is fixed to ensure that the piston moves at a constant speed inside the syringe. Therefore, it cannot be avoided that some inexperienced nurses or doctors are too fast or too slow to affect the puncture effect when extracting the effusion;

[0004] 2) It uses a nurse or doctor to manually operate the syringe, which not only cannot ensure that the nurse or doctor can extract the effusion at a uniform speed, but also increases the work intensity of the nurse or doctor;

[0005] 3) It lacks protective measures, resulting in poor antibacterial performance, easy to nourish bacteria, and poor sanitation in use
