Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for mixing platelet-rich plasma and thrombin solution. Background Art

[0002] In the medical field, it is often necessary to prepare platelet-rich plasma gel. Currently, in the process of preparing platelet-rich plasma gel, platelet-rich plasma and thrombin solution are usually added into a syringe in sequence, and then the piston of the syringe is used to pressurize the liquid in the syringe to mix them and then output them from the front end of the syringe. The operation is cumbersome and the mixing efficiency is low.

[0003] In the Chinese patent application with publication number CN214486683U, a bone powder, platelet-rich plasma, and thrombin solution mixing device is described, which can mix bone powder with platelet-rich plasma and thrombin solution. However, the mixing device is not suitable for mixing platelet-rich plasma and thrombin solution alone to prepare platelet-rich plasma gel, and in order to reduce the loss of platelet-rich plasma and thrombin solution, the diameter of the tube for transporting platelet-rich plasma and thrombin solution needs to be smaller, such as Figure 1 As shown, if a one-piece three-way joint is directly made by using a mold, two crossed slender core rods 10 need to be placed in the mold. Such a mold is difficult to make, has high cost and short life. Utility Model Content

[0004] The utility model aims to provide a device for mixing platelet-rich plasma and thrombin solution, which is easy to manufacture, has greatly reduced costs, has a long mold life, and is easy to mass produce.

The three-way joint is in the shape of a hollow shell. Its function is that through the arrangement of the mounting seats and the mounting holes on the three-way joint, when the three-way joint is made by a mold, only a core block with two outer contours of the injection needle seats and two straight tubes for forming the mounting holes needs to be placed in the mold, and there is no need to cross-arrange slender core rods in the mold, which is easy to make, greatly reduces the cost, has a long service life of the mold, and is easy to mass produce.

[0007] Furthermore, the mounting seat is provided with an injection needle seat, and the mounting hole is provided with a needle tube, which is in a Z shape and connected to the injection needle seat. The injection needle seat adopts the existing technology, and the Z-shaped needle tube can be formed by bending the linear needle tube in the existing technology.

[0011] Furthermore, the handle includes a gripping position, a slot is provided above the gripping position, and a concave surface is provided between the slot and the gripping position and at one end thereof facing the three-way joint. The function of the concave surface is to facilitate pressing the first knuckle of the index finger on the concave surface when the gripping position is held by the hand.

[0012] Furthermore, the distance between the gripping position and the three-way joint is greater than the distance between the concave surface and the three-way joint. Its function is that the distance between the push plate and the gripping position can be shortened through the positional relationship between the concave surface and the gripping position, so that the thumb can press the push plate more easily.

[0013] Furthermore, the syringe includes a first syringe for infusing platelet-rich plasma and a second syringe for infusing thrombin solution, and the inner diameter of the first syringe is larger than the inner diameter of the second syringe.

[0014] Furthermore, a non-slip strip is provided on the side of the push plate facing away from the three-way joint. The function of the non-slip strip is to prevent the thumb from slipping when pressing the push plate.
