Problems solved by technology
This thoracentesis device inevitably has the following disadvantages: (1) the puncture depth is difficult to control, especially in patients who are critically ill or have abnormally developed pectoral muscles, and the puncture is laborious or even medical accidents occur due to loss of control; (2) the drainage tube is easily blocked by pus Re-intubation and suturing are required for foreign body blockage; (3) The positioning of the drainage tube is cumbersome, etc.
This thoracentesis still inevitably has the following deficiencies: (1) with the drainage tube of the same diameter, the circumference of the patient’s chest incision is increased by 1 / 3 because the gap between the drainage tube and the puncture and drainage bifurcated sleeve is at least 1 mm (2) After the puncture is completed and the puncture and drainage bifurcated sleeve is pulled out, there is a certain gap between the drainage tube and the chest wall, and subcutaneous emphysema and mediastinal emphysema are very likely to occur, and severe cases may also be life-threatening; (3) The inserted drainage The thickness, hardness, and depth of the tube are difficult to grasp. If the drainage tube is too thin or soft, it will be blocked or bent, and the drainage effect will not be good. If the drainage tube is too hard or thick, it will cause severe pleural pain and affect sleep. And life, the drainage tube is easy to fall off if it is inserted shallowly
Another example is Chinese Patent No. 201120516080.8, which discloses "A Flushable One-way Exhaust Thoracentesis Needle", which consists of a double-sided tube wing-type puncture drainage sleeve, a drainage tube, and an integral type with a one-way valve and a flow rate regulator. The puncture needle is composed of a bilateral puncture and drainage sleeve as a drainage tube, which also has the following disadvantages in use: (1) It needs to be inserted deep, and it is easy to bend and fold when the lung recruits, or the inner opening is blocked, and the drainage effect is lost; (2) Adhesive tape is required to paste the puncture and drainage bifurcated sleeve on the surface of the patient's chest wall, which is not easy to stick firmly; (3) After the puncture needle is withdrawn, the puncture and drainage bifurcated sleeve left on the chest surface is connected to the drainage The space of the bag needs to be large, and the patient’s clothes at the puncture site cannot be close to his body, which may easily cause colds and upper respiratory tract infections; (4) can only be used for patients with pneumothorax: (5) the structure is too complicated

Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] refer to figure 1 , the prior art thoracentesis consists of a puncture and drainage bifurcated sleeve A with an abutment plate B, an integral puncture needle D, and a drainage tube C, which can puncture at the patient's chest incision and reach the patient's chest through the abutment plate After that, withdraw the integral puncture needle from the straight tube of the puncture and drainage bifurcated cannula, insert one end of the drainage tube from the fork cannula of the puncture and drainage bifurcated cannula into the chest cavity of the patient, then withdraw the puncture and drainage bifurcated cannula, and then The drainage tube is sutured and fixed on the skin and flesh around the patient's chest incision with sutures to start drainage.
[0028] Such as Figure 2 to Figure 10 Shown, a kind of thoracentesis irrigator,...

Abstract
The invention discloses a pleural cavity puncture flusher, which comprises a wide adhesive tape, a dirt can, a lotion bottle and a drainage bag, and further comprises a puncture drainage device, wherein the puncture drainage device comprises a middle segment outer thread puncture sleeve, an adjusting rotating support plate, a puncture needle head rod and a puncture needle tail rod, a T-type piston Y pipe is respectively connected with a suction washing device, an accessory inner thread drainage soft pipe, a hook needle and a cutting knife, the suction washing device comprises a suction washing ball, a suction pipe and a washing pipe, a round hole is arranged on a screw end of the puncture needle head rod, the screw end of the puncture needle head rod is connected with the puncture needle tail rod in a thread mode to be sleeved into the middle segment outer thread puncture sleeve, and the tail end of an inner thread drainage soft pipe after the puncture needle head rod and the puncture needle tail rod are taken out is connected with the drainage bag or the suction washing device. The pleural cavity puncture flusher has the advantages that the pleural cavity puncture flusher is smell in operative incisions, effectively prevents stimulation and damage to pleura and lungs of patients, reduces course of treatment, promotes cure, reduces cold of the patients, is convenient for life and normal activities of the patients, is simple in structure, low in cost and easy to select and operate and the like, and is suitable for pleural cavity puncture drainage washing of the patients.
Description
technical field [0001] The invention relates to a medical device, in particular to a thoracentesis flushing device, which is suitable for thoracentesis drainage and flushing of patients. Background technique [0002] For patients with empyema, pneumothorax and hydrothorax treated in hospitals today, the commonly used "thoracentesis drainage device" is composed of a puncture and drainage bifurcated sleeve, a drainage tube and an integral puncture needle. Perform puncture, penetrate the abutment plate and reach the patient's chest, while withdrawing the integral puncture needle from the straight tube of the puncture and drainage bifurcated sleeve, insert one end of the drainage tube from the fork sleeve of the puncture and drainage bifurcated sleeve into the patient's chest cavity, and then Withdraw the puncture and drainage bifurcated sleeve, and then use sutures to suture and fix the drainage tube on the skin and flesh around the patient's chest incision to start drainage. ...
