Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a platelet-rich plasma spray gun. Background Technology

[0002] Platelet-rich plasma (PRP) is a type of plasma containing a high concentration of platelets. It promotes tissue repair and regeneration and has wide applications in fields such as medical aesthetics, orthopedics, and dentistry. In clinical applications, PRP is usually mixed with coagulation drugs to form a platelet-rich gel, thereby exerting its therapeutic effects.

[0003] Currently, platelet-rich plasma (PRP) is mainly applied through two methods: injection and spraying. Spraying, in particular, is widely used clinically because it can evenly cover a large area of ​​wound or treatment zone. To facilitate the spraying application of PRP, various PRP spray gun devices have emerged on the market.

[0004] Existing platelet-rich plasma (PRP) spray guns typically include components such as syringes, mixing devices, and nozzles. For example, Chinese patent CN219071799U discloses a PRP therapeutic spray gun, comprising a power module, two drive devices, a U-shaped conduit, an upper support plate, a lower support plate, and a vertical plate connecting the upper and lower support plates. The upper support plate houses a PRP syringe, and the lower support plate houses an activator syringe. The two drive devices respectively drive the plungers of the two syringes. The U-shaped conduit connects the discharge ports of the two syringes and is equipped with a nozzle. While this device can accurately control the mixing ratio of PRP and activator, its complex structure, high cost, and requirement for power make it inconvenient for portable use.

[0005] In addition, existing platelet-rich plasma (PRP) spray gun devices still have the following problems: First, secondary contamination is prone to occur during the mixing of PRP and coagulation drugs, affecting the treatment effect; second, insufficient mixing can easily lead to drug flocculation, affecting platelet activity; third, uneven mixing can lead to unstable treatment effects; fourth, the current spraying method is difficult to control precisely, making it difficult to achieve uniform application; fifth, the operation may require a large pushing force, causing severe pulling sensation in the operator's palm and forefinger, affecting the user experience. These problems seriously restrict the clinical application of PRP.

[0006] Therefore, there is an urgent need for a platelet-rich plasma spray gun that is simple in structure, mixes evenly, is easy to operate, and is comfortable to use, in order to improve the clinical application effect of platelet-rich plasma. Utility Model Content

[0007] The purpose of this invention is to provide a platelet-rich plasma spray gun to solve the problems of secondary pollution, easy flocculation, uneven mixing, and severe pulling sensation in the palm and forefinger of the operator caused by the existing methods of mixing platelet-rich plasma and coagulation drugs.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0009] A platelet-rich plasma spray gun includes: a handle, a main syringe, an auxiliary syringe, a push plate, a three-way connector, a nozzle, and an atomizing plug. The main syringe is detachably mounted on the handle. The auxiliary syringe is arranged parallel to the main syringe. The push ends of both the main syringe and the auxiliary syringe are detachably fixed to the push plate. The injection ends of both syringes are connected to two ports of the three-way connector. The other end of the three-way connector is connected to the nozzle. An atomizing plug is provided at the spray outlet of the nozzle.

[0010] Furthermore, it also includes a mixing column and a liquid passing column. The nozzle has a hollow cylindrical structure, with a mixing column fixedly installed in the middle section of its inner cavity. The liquid passing column is located at the spray end and is connected to the mixing column at one end.

[0011] Furthermore, it also includes a threaded groove, a drain outlet, and a diversion groove. The threaded groove is located on the outside of the mixing column and its external dimensions are adapted to the inner diameter of the nozzle. A drain outlet is located at the end of the threaded groove and is connected to the diversion groove, which is a V-shaped groove located on the surface of the liquid column.

[0012] Furthermore, it also includes Luer connectors, connecting plates, and liquid outlet holes. The tee connector has two Luer connectors at the connection end, and the two Luer connectors are connected to the liquid outlet holes using two independent flow channels. A connecting plate is provided between the flow channels.

[0013] Furthermore, the push plate also includes an auxiliary slot, a main slot, a main push part, and an auxiliary push part. The main slot and the auxiliary slot are disposed on the surface of the main push part. The main slot and the auxiliary slot are offset and their installation positions correspond to the tails of the main syringe and the auxiliary syringe. The auxiliary push part is located below the main push part.

[0014] Furthermore, both the main pusher and the auxiliary pusher are adapted to bendable flat plate structures, with the auxiliary pusher being further bent towards the auxiliary slot end relative to the main pusher.

[0015] This utility model has the following beneficial effects:

[0016] The main and auxiliary syringes and the nozzle are connected by a three-way connector with a Luer connector, enabling the separation and storage of platelet plasma and thrombin. The spiral mixing column inside the nozzle ensures that the platelet plasma and thrombin are fully mixed before being sprayed onto the wound, preventing secondary contamination and maintaining the therapeutic effect of platelets. The atomizing plug design allows the mixture to be sprayed evenly in a mist form, solving the problems of inconvenient control and uneven application in traditional application methods. The handle and push plate at the rear of the spray gun are ergonomically designed, and the curved flat structure of the main and auxiliary push parts, as well as the staggered main and auxiliary locking slots, effectively reduce the pulling sensation of the operator's palm and thumb, improving the user experience.

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 , 2 As shown, the specific implementation of the platelet-rich plasma spray gun of this utility model is as follows: The spray gun mainly consists of a handle 1, a main injector 2, an auxiliary injector 3, a push plate 4, a three-way connector 5, a nozzle 6, and an atomizing plug 7. The main injector 2 is detachably mounted on the main support of the handle 1, and the auxiliary injector 3 is arranged parallel to the main injector 2. The pushing ends (i.e., the tails) of the main injector 2 and the auxiliary injector 3 are respectively snapped into the main slot 42 and the auxiliary slot 41 of the push plate 4, realizing the synchronous advancement of the two injectors. The injection ends of the two injectors are sealed and screwed together through two Luer connectors 51 at the rear end of the three-way connector 5, and the front end of the three-way connector 5 is threadedly connected to the nozzle 6.

[0028] As attached Figure 3 , 4 As shown in Figure 5, the nozzle 6 adopts a hollow cylindrical structure, with a mixing column 61 fixedly installed in the middle section of its inner cavity. The outer surface of the mixing column 61 is provided with a spiral threaded groove 62, and the contour dimensions of the threaded groove 62 are precisely matched with the inner wall of the nozzle 6 to form a spiral mixing channel. A liquid outlet 63 is axially opened at the front end of the mixing column 61, and the liquid outlet 63 is connected to the liquid-passing column 64 at the front section of the nozzle 6. The surface of the liquid-passing column 64 is machined with a V-shaped cross-section guiding groove 65, and the end of the guiding groove 65 abuts against the atomizing plug 7. The atomizing plug 7 is pressed into the spray port of the nozzle 6, and its center is provided with a micron-level spray hole. The inner wall is provided with a limiting protrusion to achieve a tight fixation.

[0029] As attached Figure 7 As shown, the three-way connector 5 is divided into two independent flow channels by a connecting plate 52, which are respectively connected to the two Luer connectors 51 and the outlet port 53. This design ensures that the platelet-rich plasma in the main injector 2 and the thrombin in the auxiliary injector 3 are completely isolated before reaching the outlet port 53.

[0030] As attached Figure 6 As shown, the push plate 4 adopts an ergonomic design. Its main push part 43 is a slightly curved flat plate structure with a main slot 42 and an auxiliary slot 41 offset on its surface to accommodate syringes of different sizes. An auxiliary push part 44 extends from below the main push part 43. This auxiliary push part 44 is further bent towards the auxiliary slot 41 to form a larger arc, making it easier for operators with smaller hands to apply force with the base of their thumbs. The handle 1 adopts a backward tilting design, which works in conjunction with the curved structure of the push plate 4 to reduce the pulling sensation in the web of the hand.

[0031] The specific usage of this utility model is as follows:

[0032] During operation, the thumb pushes the push plate 4, causing the dual syringe plungers to move forward synchronously. Platelet-rich plasma and thrombin are injected into the threaded groove 62 through the outlet hole 53 via independent channels of the three-way connector 5. The two liquid flows generate swirling flow within the spiral mixing channel, achieving thorough mixing. The mixture then enters the drainage groove 65 through the drain hole 63, guiding it to the atomizing plug 7, and finally atomizes into a uniform spray under pressure. The sealing connection and closed flow channel design of the Luer connector 51 effectively prevent leakage and secondary contamination of biological agents, while the swirling mixing mechanism of the threaded groove 62 solves the problems of uneven mixing and flocculation in traditional methods. The double-arc structure of the push plate 4 and the tilt design of the handle 1 significantly improve operating comfort, especially reducing muscle fatigue during prolonged use.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
