Embodiment Construction

[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0016] Such as figure 1 and figure 2 As shown, the present invention provides a rat femoral artery blood collection device, comprising a first fixture 100 and a second fixture 200, one end of the first fixture 100 and the second fixture 200 are hinged, and the other end is detachably connected by a locking member 700 . The first fastener 100 includes an elastic transparent airbag section 120, a locking plate 110, and a hinged section 130. The elastic transparent airbag section 120 has an arc-shaped structure and is made of a mixture of silica gel and polypropylene, so that the material is elastic and transparent After the air bag segment 120 is punctured, no liquid or gas will leak out. One end of the elastic transparent airbag section 120 i...

Abstract

The invention discloses a rat femoral artery blood sampling device which comprises a first fixing piece and a second fixing piece, one ends of the first fixing piece and the second fixing piece are hinged, the other ends of the first fixing piece and the second fixing piece are detachably connected through a locking piece, the first fixing piece comprises an elastic transparent air bag section, a locking plate and a hinge section, one end of the elastic transparent air bag section is fixedly connected with the locking plate, the other end of the elastic transparent air bag section is fixed to the arc-shaped hinge section, the elastic transparent air bag section is filled with normal saline, a switch plug is arranged on the elastic transparent air bag section, the structure of the second fixing piece is consistent with that of the first fixing piece, the elastic transparent air bag section on the second fixing piece is filled with gas, a telescopic supporting frame is arranged on the second fixing piece, the top of the telescopic supporting frame is connected with a connecting plate, the connecting plate is connected with a hemostix through an inclined groove, a needle body on the hemostix faces the elastic transparent air bag section in the first fixing piece, a coating section is arranged at the tip end of the needle body of the hemostix, the surface of the coating section is coated with an expansion sponge film, blood sampling can be completed, the blood sampling site can be compressed to stop bleeding without ligating the blood vessel.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a rat femoral artery blood collection device. Background technique [0002] Rodent rats are often used as animals for laboratory pharmacokinetic research. During the experiment, blood from various parts of the rat is usually collected for research, and femoral artery blood collection is one of the common blood collection methods. In the existing femoral artery blood collection, due to the destruction of the blood vessel wall structure during blood collection, good hemostasis measures are lacking. In order to avoid continuous bleeding from the wound caused by the blood collection needle, it is necessary to permanently ligate the blood vessel. However, the femoral artery is the main blood vessel nourishing the distal extremities. After ligation, the blood supply of the distal extremities will be seriously affected, which will further affect its motor sensory function. There...
