Embodiment 1

[0091] Such as Figure 1-3 As shown, the embodiment of the present invention provides a platelet-rich plasma (PRP) spray gun device, including:

[0092] The storage room 1 is equipped with a platelet-rich plasma storage room 2 and a thrombin storage room 3;

[0093] The metering pump group 4 includes a platelet-rich plasma metering pump 41 and a thrombin metering pump 42. The inlet of the platelet-rich plasma metering pump 41 is connected to the platelet-rich plasma storage 2, and the inlet of the thrombin metering pump 42 is connected to the thrombin metering pump. Storage 3 connection;

[0094] The storage agitator 6 includes: a temporary storage 61, which includes two agitator inlets 62, respectively connected to the outlet of the platelet-rich plasma metering pump 41 and the outlet of the thrombin metering pump 42, and a stirring component 64 is arranged inside the temporary storage 61; Self-priming pump 65, the inlet is connected to the temporary storage 61, and the out...

Embodiment 2

[0104] On the basis of embodiment 1

[0105] The storage chamber 1 is provided with a master control switch 7 and a digital display touch screen 8, the master control switch 7 is electrically connected to a power supply, the digital display touch screen 8, platelet-rich plasma metering pump 41, thrombin metering pump 42 And the self-priming pump 65 is electrically connected with the master control switch 7 .

[0106] The digital display touch screen is a current touch display / touch panel (such as a PLC control panel, refer to CN210612471U), and control parameters can be set on the digital display touch screen (such as setting the platelet-rich plasma extracted by the corresponding metering pump) or thrombin volume); preferably, the digital display touch screen can also be provided with different control switches (or control buttons, which can include the current start switch) for controlling corresponding electrical devices (such as self-priming pumps);

[0107] The working p...

Embodiment 3

[0109] On the basis of embodiment 2

[0110] The suction pipe of the metering pump is connected with the thread port of the corresponding storage;

[0111] An opening is set at the lower end of the storage chamber, and an open bottom plate 11 is set inside the opening, and the open bottom plate 11 is used to seal or open the opening.

[0112] The operation principle of above-mentioned technical scheme is: the operation process of the present invention can be as follows:

[0113] Step 1: Put the extracted platelet-rich plasma and thrombin into the platelet-rich plasma storage and the thrombin storage respectively, open the open bottom plate, connect the platelet-rich plasma storage, the thrombin storage and the metering pump suction tube with silk The mouth is tightly connected, and then the open bottom plate is closed;

[0114] Step 2: According to the actual demand for platelet-rich plasma and thrombin, adjust the suction volume of platelet-rich plasma metering pump and thr...

Abstract

The invention provides a platelet-rich plasma (PRP) spray gun device, comprising: a storage accommodating chamber with a platelet-rich plasma storage and a thrombin storage inside; a metering pump group, including a platelet-rich plasma metering pump and a thrombin metering pump , the platelet-rich plasma metering pump inlet is connected to the platelet-rich plasma reservoir, and the thrombin metering pump inlet is connected to the thrombin reservoir; the storage agitator includes: a temporary reservoir, which includes two agitator inlets, respectively The outlet of the platelet-rich plasma metering pump and the outlet of the thrombin metering pump are connected, and a stirring component is arranged inside the temporary storage; the inlet of the self-priming pump is connected with the temporary storage, and the outlet of the self-priming pump is the outlet of the agitator; One end of the pipe is connected to the outlet of the agitator, and the other end is connected to the spray gun. The present invention has the advantage that PRP and thrombin can be uniformly mixed in a specific ratio.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a platelet-rich plasma (PRP) spray gun device. Background technique [0002] Platelet rich plasma (platelet rich plasma, PRP) refers to the platelet concentrate obtained from whole blood by centrifugal technology, containing high concentration of platelets, when mixed with thrombin, the platelets are activated and release a large amount of growth factors, thereby promoting the body to heal . Before using PRP, PRP and thrombin are usually mixed in a specific ratio to activate platelets, thereby stimulating the platelets to release growth factors. Therefore, how to mix the extracted PRP and thrombin in a specific ratio and uniformly is the key to the application of PRP. The PRP spray gun device currently used clinically cannot uniformly mix PRP and thrombin in a specific ratio. Contents of the invention [0003] The present invention provides a platelet-rich plasma (PRP...
