Description

A thoracentesis and drainage device capable of automatic positioning

technical field

The invention belongs to the technical field of medical devices, in particular to a thoracocentesis and drainage device capable of automatic positioning.

Background technique

When it comes to thoracentesis, many patients always feel scared. It’s not as easy to accept the needle on the buttocks, but piercing the chest cavity. There are heart and lungs in the chest cavity, so I can’t help but feel a little scared. What should I do if I puncture it? Will it be dangerous? What should the doctor pay attention to? What patients should pay attention to and how to cooperate well, this is what we should know. According to the operating procedures, the risk can be said to be almost non-existent.

First of all, we should know the role of thoracentesis in the diagnosis and treatment of thoracic diseases. In the clinical work of the pulmonary department, thoracentesis is a relatively common, convenient and simple method of diagnosis and treatment. For example: Through inspection, we found that there is effusion in the patient's pleural cavity, and the fluid can be extracted through thoracentesis, and various examinations can be performed to find the cause of the disease. If there is a lot of effusion in the cavity, oppressing the lungs or the effusion lasts too long, the fibrin in it is easy to organize and two layers of pleural adhesion will occur, which will affect the respiratory function of the lungs. At this time, we also need to puncture to remove the effusion. Drugs can also be injected to achieve therapeutic purposes if necessary. Such as pleural effusion caused by cancer, we inject anticancer drugs to play an anticancer effect. If there is too much gas in the pleural cavity and the pleural cavity has changed from negative pressure to positive pressure, then this operation can also be used to decompress and pump out the gas. If the patient has a bronchi that communicates with the pleural cavity, then we inject a blue drug (called methylene blue, which is harmless to the human body) into the chest cavity through a puncture needle, then the patient can cough up the blue color when coughing. If there is any fluid (including sputum), we can confirm that the patient has a bronchopleural fistula. Bronchopleural fistula is a pathological channel established due to pulmonary lesions involving the bronchi, alveoli, and pulmonary pleura. To clarify the nature of the pleural effusion, a thoracentesis is required to aid in the diagnosis; for patients with a large amount of effusion or pneumatosis that causes pulmonary compression symptoms, and for patients with empyema, fluid extraction is required for treatment; drugs must be injected into the pleural cavity Wait.

At present, thoracentesis and drainage are performed by doctors using medical equipment, the accuracy is not high, and the hands will shake slightly during the operation, which is prone to danger for patients. Therefore, an automatic thoracentesis and drainage device is designed. It is very necessary.

Contents of the invention

Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a thoracentesis and drainage device that can be positioned automatically.

The technical solution of the present invention is: a thoracentesis and drainage device that can be positioned automatically, mainly including a fixed chair, an ultrasonic positioning device, a puncture device, a control device and a computer.

Further, the locator includes a puncture point positioning function and a puncture depth positioning function. The puncture short positioning function allows the puncture needle to penetrate into the correct position, and the puncture depth positioning can prevent the puncture needle from being too shallow and cause the effusion to be unable to be drawn out or punctured. Penetrating too deeply can cause injury to the patient.

Further, pedals are provided between the legs of the chair, and fixing belts are provided on the pedals to fix the patient's lower limbs during the puncture and drainage process, so as to prevent lower limb activities from affecting the puncture and drainage process.

Further, the back of the chair is connected with the seat by a sleeve rod, the height of the back of the chair can be adjusted up and down through the sleeve and the positioning knob, and the height of the back of the chair can be adjusted, thereby adjusting the height of the ultrasonic positioning device to adapt to patients of various sizes use.

Further, the liquid suction tube and the medicine feeding tube are in a separate state inside the puncture needle, and when the puncture needle enters the patient's body, the liquid suction tube and the medicine feeding tube can work independently, avoiding repeated puncturing of the liquid suction and medicine feeding and draw out.

Further, the range of movement of the needle handle is the same as the area of the ultrasonic positioning device, and within the range of ultrasonic positioning, the needle handle can ensure accurate puncture and drainage and avoid surgical errors.

Further, the flow valve 1 and the flow valve 2 have an excessive automatic closing function, and each time the pleural effusion is drawn must not exceed 600ml, and the flow valve 1 is automatically closed when the volume of the extracted effusion exceeds 600ml, and the flow valve 2 can monitor Injection dose, to avoid injecting drug overdose.

The working method of the present invention is: a kind of thoracentesis and drainage device that can be positioned automatically provided by the present invention, before starting to perform thoracentesis and drainage, guide the patient to sit on the fixed chair facing the back of the chair, step on the pedals, Use the fixing belt to fix the patient's feet, then put the chest against the back of the chair, adjust the height of the ultrasonic positioning device to be parallel to the patient's chest through the positioning knob, put the patient's arm flat on the body board, and keep the forehead close to the arm, keeping a fixed posture. The ultrasonic positioning device performs ultrasonic positioning on the patient's pleural effusion according to the ultrasonic wave, and forms a holographic image and sends it to the computer for analysis and processing, and then transmits the data to the control device, and the puncture needle is inserted into the designated position in the patient's body through the needle handle controller , and then according to the patient's condition, the effusion in the patient's body is drawn out through the liquid pumping controller or the patient is injected with medicine through the medicine feeding controller, and the extracted effusion is stored in the collection tank.

The beneficial effects of the present invention are: a thoracentesis and drainage device that can be positioned automatically provided by the present invention is suitable for operation on patients with pleural effusion or pneumatosis. Compared with the prior art, the present invention uses ultrasonic positioning The device scans the position of the affected part of the patient's body, and forms a holographic image and sends it to the computer. The control device controls the needle handle to pierce the puncture needle into the designated position in the patient's body for fluid extraction. When a certain amount is extracted, the flow valve is automatically closed to avoid Too much suction at one time causes discomfort to the patient, and the drug inlet tube and the liquid suction tube are integrated in the puncture needle at the same time, avoiding the need for repeated puncture for drug injection and liquid suction. In a word, the present invention has the advantages of novel structure, comprehensive functions, safety and high efficiency.
