Abstract

The utility model discloses a thoracentesis needle fixator, which belongs to the technical field of medical auxiliary instruments. The thoracentesis needle fixator is composed of a fixed plate (1), sucking discs (2), elastic clamp arms (3) and clamp plates (4); and the thoracentesis needle fixator is characterized in that the bottom surfaces of the two ends of the rectangular fixed plate (1) are respectively provided with a sucking disc (2), the upper surfaces of the two ends of the rectangular fixed plate (1) are respectively connected and fastened with an elastic clamp arm (3), the two elastic clamp arms (3) are mutually symmetrical, and the outer sides of the two elastic clamp arms (3) are respectively provided with a ring (5), the upper ends of the elastic clamp arms (3) are respectively connected and fastened with a clamp plate (4), and the two clamp plates (4) are mutually symmetrical, the opposite surfaces of the clamp plates (4) are respectively provided with a longitudinal clamp slot, the two longitudinal clamp slots correspond to each other, and the middle part of the front end face of the fixed plate (1) is provided with a U-shaped gap opposite to the longitudinal clamp slots. The thoracentesis needle fixator disclosed by the utility model is simple in structure and convenient to operate, fixes a thoracentesis needle firmly, and can effectively prevent the thoracentesis needle from swinging or being pulled by a catheter, thereby guaranteeing that pleural effusions are aspirated smoothly.

Description

The thoracentesis needle lock

Technical field: this utility model belongs to the medical auxiliary apparatus technical field, specifically a kind of thoracentesis needle lock.

Background technology: at present, the device that extracts hydrothorax mainly contains puncture needle, conduit, syringe formation, when from the thoracic cavity, extracting hydrops, puncture needle is inserted into intrathoracic hydrops position reuse syringe and extracts.But after puncture needle was inserted into the thoracic cavity, the upper end of puncture needle is easy to produce swing or by the conduit pulling, 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.

The order of this utility model is achieved in that this thoracentesis needle lock is made up of fixing head, sucker, elasticity jig arm, clamping plate; Bottom surface, rectangle fixing head two ends is respectively equipped with sucker; Connect respectively above the two ends and fixing the elasticity jig arm that the symmetrical outside is provided with finger ring; Elasticity jig arm upper end connects is respectively fixing symmetrical clamping plate, is respectively equipped with vertical clip slot of mutual correspondence on the clamping plate opposite face, and fixing head front end face middle part has and vertical relative " U " v notch v of clip slot.

After puncturing successfully, again fixing head is absorbed and fixed at patient's thoracic wall after puncture needle snapped in " U " v notch v above the fixing head, finger inserts finger ring and the elasticity jig arm is opened with clamping plate puncture needle to be gripped gets final product then.

The advantage of this utility model: simple in structure, easy and simple to handle, to the puncture needle fixation, can effectively prevent the puncture needle swing or, guarantee the smooth extraction of hydrothorax by the conduit pulling.

Description of drawings: accompanying drawing 1 is the structure chart of this utility model.

The specific embodiment: describe in further detail below in conjunction with 1 pair of this utility model of accompanying drawing: this thoracentesis needle lock is made up of fixing head 1, sucker 2, elasticity jig arm 3, clamping plate 4; Bottom surface, rectangle fixing head 1 two ends is respectively equipped with sucker 2; Connect respectively above the two ends and fixing the elasticity jig arm 3 that the symmetrical outside is provided with finger ring 5; Elasticity jig arm 3 upper ends connect fixing symmetrical clamping plate 4 respectively; Be respectively equipped with vertical clip slot of mutual correspondence on clamping plate 4 opposite faces, fixing head 1 front end face middle part has and vertical relative " U " v notch v of clip slot.
