Abstract
The utility model discloses a thoracic cavity puncture needle fixing device, and relates to the technical field of medical treatment auxiliary tools. The thoracic cavity puncture needle fixing device comprises a rectangular fixing plate, square sleeves, pulling rods, supporting springs and clamping plates, and is characterized in that a U-shaped notch is formed in the middle of the front end face of the rectangular fixing plate with a bonding layer arranged on the bottom face, the mutually-symmetrical square sleeves are fixed at the left end and the right end of the rectangular fixing plate respectively, the pulling rods which are matched with inner cavities of the square sleeves are sleeved inside the square sleeves respectively in a sliding mode, the outer end of each pulling rod is provided with a ring, the clamping plates which are mutually symmetrical are perpendicularly fixed at two opposite ends of the two pulling rods respectively, and the supporting springs are sleeved at the portions, between the clamping plates and the square sleeves, of the pulling rods. The thoracic cavity puncture needle fixing device is simple in structure, convenient to use, firm in fixation of a puncture needle, capable of effectively preventing the puncture needle from swinging or being pulled by a catheter, capable of ensuring smooth pumping of pleural effusion and capable of relieving pain of a patient and labor intensity of medical care workers.
Description
Technical field: this utility model relates to medical appurtenance technical field, specifically a kind of thoracentesis needle lock.
Background technology: after producing hydrops in the patient thoracic cavity, need as soon as possible hydrops to be extracted from the thoracic cavity.At present, the device that extracts hydrops mainly contains puncture needle, conduit, syringe formation, when extracting hydrops from the thoracic cavity, puncture needle is inserted into intrathoracic hydrops position, and the reuse syringe extracts.But after puncture needle was inserted into the thoracic cavity, the puncture needle upper end was easy to generate swing or is spurred by conduit, and the pin hole that causes syringe needle to produce displacement or syringe needle front end gets clogged because of displacement, influences carrying out smoothly of drawing liquid.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can be with the thoracentesis needle fixation, the thoracentesis needle lock that prevents its swing or be pulled.
Order of the present utility model is achieved in that this thoracentesis needle lock comprises rectangle fixing head, square casing, pumping rod, support spring, clamping plate, the rectangle fixing head front end face middle part that the bottom surface is provided with adhesive linkage is provided with " U " v notch v, fixing symmetrical square casing above the two ends, the left and right sides respectively, the suit that slides respectively in the square casing the pumping rod that the outer end that adapts with its inner chamber is provided with finger ring, the difference vertical fixing symmetrical clamping plate on two pumping rod opposite ends, is with support spring on the pumping rod between clamping plate and the square casing.
After puncturing successfully, forefinger and thumb insert behind two finger rings above the pumping rod outer end respectively and spur pumping rod, then puncture needle is snapped in behind " U " v notch v above the fixing head and with fixing head and be adhesively fixed on patient's chest outer wall, loosening pumping rod at last can grip puncture needle at the effect lower plate of support spring.
Advantage of the present utility model: simple in structure, easy to use, to the puncture needle fixation, can effectively prevent puncture needle swing or spurred by conduit, guarantee the smooth extraction of hydrothorax, can alleviate the painful and medical personnel's labor intensity of patient.
Description of drawings: Fig. 1 is front view of the present utility model; Fig. 2 is vertical view of the present utility model.
The specific embodiment: below in conjunction with Fig. 1, Fig. 2 is, and this utility model describes in further detail: this thoracentesis needle lock comprises rectangle fixing head 1, square casing 2, pumping rod 3, support spring 4, clamping plate 5, the rectangle fixing head 1 front end face middle part that the bottom surface is provided with adhesive linkage 6 is provided with " U " v notch v, fixing symmetrical square casing 2 above the two ends, the left and right sides respectively, the suit that slides respectively in the square casing 2 pumping rod 3 that the outer end that adapts with its inner chamber is provided with finger ring 7, the difference vertical fixing symmetrical clamping plate 5 on two pumping rod 3 opposite ends, is with support spring 4 on the pumping rod 3 between clamping plate 5 and the square casing 2.
