[0002] A powder delivery device is a tool used to efficiently and accurately deliver granular or powdered materials or drugs to the desired site. It is commonly used in surgical procedures, wound care, and other similar settings to enable rapid onset of action and reduce the risk of infection. Currently, during use, powder delivery devices are prone to clogging due to the small outlet of the storage bottle. Relying solely on the negative pressure of the airflow from an air pump is insufficient to clear this blockage, thus reducing the drug delivery rate. Utility Model Content

[0003] The purpose of this invention is to provide a powder delivery device with anti-clogging function. It features a detachable gun body, nozzle, and hose, and a detour pipeline connected to a three-way valve at the bottom of the drug storage bottle. The three-way valve has two states: ventilation and drug delivery. In the ventilation state, gas is allowed to enter only into the drug storage bottle, preventing drug powder from clogging the outlet of the drug storage bottle, thus solving the problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A powder delivery device with anti-clogging function includes a gun body, a nozzle, and a hose. A three-way valve and a ball valve core are provided inside the nozzle. The three-way valve is provided with an A connector, a B connector, and a C connector. The A connector is connected to an air tube located inside the gun body, and the B connector is connected to the hose. A medicine storage bottle is vertically installed at the top of the nozzle, and a meandering pipe at the bottom of the medicine storage bottle is connected to the C connector.

[0006] Furthermore, a drug guide tube is provided at the center of the bottom of the medicine storage bottle, which is connected to the side of the B-connector, and the meandering pipeline is adjacent to the inner wall of the medicine storage bottle.

[0007] Furthermore, the ball valve core is provided with a T-shaped passage inside, and the three ports of the T-shaped passage are rotatably connected to the A-connector, B-connector and C-connector respectively.

[0008] Furthermore, a rotating rod penetrating the side of the nozzle is provided at the center of the side of the spherical valve core.

[0009] Furthermore, a sealing ring is provided between the three-way valve and the ball valve core.

[0010] Furthermore, a mounting ring is provided at the end of the nozzle near the gun body, and the mounting ring is threadedly connected to the end of the gun body.

[0011] Furthermore, the gun body contains an air pump connected to an air pipe.

[0012] Furthermore, a fixing rod is provided on the outer periphery of the air pump and connected to the inner wall of the gun body.

[0013] Furthermore, a handle for mounting a battery and a switch is provided at the bottom of the gun body. The battery is electrically connected to the air pump, and the switch is used to drive the air pump to open and close.

[0014] Furthermore, the gun body is made of polytetrafluoroethylene, the nozzle is made of ABS, and the hose is made of silicone.

[0015] The beneficial effects of this utility model are:

[0016] This invention features a detachable gun body, nozzle, and hose. A circuitous pipeline connected to a three-way valve is located at the bottom of the medicine storage bottle. The three-way valve contains a spherical valve core. Rotating the spherical valve core with a lever changes the position of the T-shaped passage, allowing the three-way valve to operate in both ventilation and drug delivery modes. In ventilation mode, gas only enters the outlet of the medicine storage bottle, preventing drug powder from accumulating and clogging the outlet, thus improving drug delivery efficiency. In drug delivery mode, the drug powder in the storage bottle is delivered to the affected area via a drug delivery tube, B-connector, and hose under the action of an air pump, while preventing backflow at the end of the drug delivery tube.

[0024] Example 1

[0025] Embodiment 1 of this utility model is a powder delivery device with anti-clogging function, including a gun body 1, a nozzle 2 and a hose 3. A three-way valve 21 and a ball valve core 22 located inside the three-way valve 21 are provided in the nozzle 2. The three-way valve 21 is provided with an A-connector 210, a B-connector 211 and a C-connector 212 respectively. The A-connector 210 is connected to an air tube 130 located in the gun body 1. The B-connector 211 is connected to the hose 3. A medicine storage bottle 4 is vertically arranged at the top of the nozzle 2. A meandering pipe 41 arranged at the bottom of the medicine storage bottle 4 is connected to the C-connector 212.

[0026] Reference Figures 1 to 3 This utility model mainly involves setting a three-way valve 21 inside the nozzle 2. The A-connector 210, B-connector 211, and C-connector 212 of the three-way valve 21 are connected to the air pipe 130, the hose 3, and the detour pipe 41, respectively. During the rotation of the ball valve core 22, the corresponding A-connector 210, B-connector 211, or C-connector 212 are opened or closed. Here, B-connector 211 and C-connector 212 are mainly opened or closed. A-connector 210 needs to be connected to B-connector 211 or C-connector 212, so as to put the three-way valve 21 into the drug delivery state or the air supply state.

[0027] In the drug administration state, a drug delivery tube 40 is provided at the center of the bottom of the drug storage bottle 4, which communicates with the side of the B-connector 211. The meandering pipe 41 is adjacent to the inner wall of the drug storage bottle 4, as shown in the figure. Figure 1As shown, with C connector 212 closed, the air pump 13 passes through air tube 130, A connector 210, ball valve core 22, and B connector 211. At the same time, the medicine powder in the medicine storage bottle 4 is introduced into the affected area through the medicine delivery tube 40, B connector 211, and hose 3 under the action of the air pump 13, while preventing backflow at the end of the medicine delivery tube 40.

[0028] During ventilation, refer to Figure 2 As shown, with B connector 211 closed, the air pump 13 is directly connected to C connector 212 and the bypass pipeline 41 via air pipe 130 and A connector 210, allowing gas to circulate at the outlet at the bottom of the medicine storage bottle 4, thereby preventing the accumulation and blockage of drug powder at the outlet and reducing the drug administration effect and rate during drug administration.

[0029] In some preferred embodiments, the spherical valve core 22 has a T-shaped passage 220 inside, and the three ports of the T-shaped passage 220 are rotatably connected to the A-connector 210, B-connector 211, and C-connector 212, respectively. The T-shaped passage 220 facilitates communication between the spherical valve core 22 and the A-connector 210, B-connector 211, and C-connector 212 in the three-way valve 21. The position of the spherical valve core 22 can be adjusted by rotation according to the desired state to meet the requirements of drug delivery and ventilation.

[0030] The rotation of the spherical valve core 22 is mainly achieved through the rotation of the rotating rod 23. The rotating rod 23 is located at the center of the side of the spherical valve core 22, penetrating the side of the nozzle 2. The rotating rod 23 penetrates the side of the nozzle 2, and a sealing structure is provided between the two, which is existing technology and will not be described in detail here. This ensures that the rotation does not affect the gas transmission of the air pump 13. At the same time, a T-mark corresponding to the T-shaped passage 220 is provided on the outer end of the rotating rod 23, which is used to rotate the spherical valve core 22, adjust the position of the T-shaped passage 220, and open or close the A-connector 210, B-connector 211, and C-connector 212.

[0031] In some preferred embodiments, a sealing ring 24 is provided between the three-way valve 21 and the ball valve core 22. The sealing ring 24 facilitates the closure of the remaining pipe when any two pipes are opened, ensuring a seal. The sealing ring 24 can be made of rubber, and its thickness can be set according to actual conditions to meet the sealing performance requirements of the ball valve core 22 and the three-way valve 21. This will not be elaborated further here.

[0032] Example 2

[0033] This embodiment 2 is implemented based on embodiment 1. A mounting ring 20 is provided at the end of the nozzle 2 near the end of the gun body 1, and the mounting ring 20 is threadedly connected to the end of the gun body 1. The air pump 13 is connected to the air pipe 130 inside the gun body 1. The outer diameter of the mounting ring 20 is adapted to the inner diameter of the gun body 1, and a threaded connection is used for detachable connection, allowing the gun body 1 to be reused. Meanwhile, the A-connector 210, B-connector 211, and C-connector 212 of the three-way valve 21 are respectively embedded in the air pipe 130, the hose 3, and the detour pipe 41, and can be removed sequentially.

[0034] In some preferred embodiments, a fixing rod 131 is provided on the outer periphery of the air pump 13 and connected to the inner wall of the gun body 1. The fixing rod 131 ensures the stable installation of the air pump 13 and extends the service life of the air pump 13 within the gun body 1. The number and specifications of the fixing rods 131 can be set according to specific circumstances.

[0035] In some preferred embodiments, the bottom of the gun body 1 is provided with a handle 10 for mounting a battery 11 and a switch 12. The battery 11 is electrically connected to the air pump 13, and the switch 12 is used to drive the air pump 13 to open and close. The switch 12 may be boat-shaped, and the switch 12 may be positioned at the index or middle finger position to trigger the air pump 13 to open or close.

[0036] In some preferred embodiments, the gun body 1 is made of polytetrafluoroethylene, the nozzle 2 is made of ABS, and the hose 3 is made of silicone.

[0037] The working principle of this utility model is as follows: In use, by rotating the lever 23, the position of the T-shaped passage 220 inside the ball valve core 22 is adjusted, so that the three-way valve 21 is in either the ventilation state or the drug delivery state. In the ventilation state, the B connector 211 is closed, allowing the air pump 13 to connect directly to the C connector 212 and the bypass pipeline 41 via the air pipe 130, the A connector 210, and the air pipe 41. This allows gas to circulate at the outlet at the bottom of the medicine storage bottle 4, thereby preventing the accumulation and blockage of drug powder at the outlet, which would reduce the drug delivery effect and rate during the drug delivery state. In the drug delivery state, the C connector 212 is closed, and the air pump 13, through the air pipe 130, the A connector 210, the ball valve core 22, and the B connector 211, allows the drug powder in the medicine storage bottle 4 to be delivered to the affected area under the action of the air pump 13 via the drug delivery tube 40, the B connector 211, and the flexible tube 3, while preventing backflow at the end of the drug delivery tube 40.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
