[0069] In addition, in the above description, since the spray head 4 is connected to the flow guide pipe 501, the rotation of the ball seat 3 driven by the motor 703 is forward and reverse rotation, that is, the ball seat 3 rotates forward for one circle and then reversely for one circle, and the process is repeated in sequence to ensure the stability of the flow guide pipe 501 in guiding the drug liquid, and the flow guide pipe 501 adopts a spiral shape and can be elongated to a certain extent.

[0070] Embodiment three

[0071] As shown in the above description, the spray head 4 is connected to the flow guide pipe 501, so that the rotation of the ball seat 3 driven by the motor 703 is forward and reverse rotation, that is, the ball seat 3 rotates forward for one circle and then reversely for one circle, and the process is repeated in sequence to ensure the stability of the flow guide pipe 501 in guiding the drug liquid, and the flow guide pipe 501 adopts a spiral shape and can be elongated to a certain extent. Figure 5 And Figure 9 As shown, on the basis of embodiment one, in order to enable the liquid suction port of the drug delivery module 5 to communicate with the inner cavity of the medicine bottle 2 installed in the bottle groove 101, the liquid suction port of the drug delivery module 5 is provided with a connecting cover 10, and the middle part of the connecting cover 10 is provided with a plug 1001 for inserting into the medicine bottle 2.

[0072] The mouth part of the medicine bottle 2 is provided with a bottle cap 201, the middle part of the bottle cap 201 is provided with a plug hole 202 for inserting the plug 1001, and the bottle cap 201 is provided with a suction pipe 203, and the lower end of the suction pipe 203 extends to the bottom of the medicine bottle 2.

[0073] When the plug 1001 is inserted into the inside of the socket 202, the plug 1001 communicates with the upper end of the suction tube 203.

[0074] When the medicine injection operation is completed, if there is still medicine left in the medicine bottle 2, the medicine bottle 2 can be removed from the inside of the bottle groove 101, a cover for sealing the socket 202 is covered on the bottle cap 201 of the medicine bottle 2, and then the medicine bottle 2 is placed in the inside of the refrigerator for low-temperature preservation, thereby facilitating the preservation of the remaining medicine in the medicine bottle 2.

[0075] The inside of the connecting cover 10 is provided with two annular frames 11, and a filter membrane 12 is clamped between the two annular frames 11;

[0076] When the connecting cover 10 is fixed to the liquid suction port of the medicine injection module 5, the filter membrane 12 is fixed between the liquid suction port of the medicine injection module 5 and the connecting cover 10 through the two annular frames 11;

[0077] The cell medicine has the risk of depositing at the bottom of the medicine bottle 2 due to gravity, and manual mixing of the cells in the medicine bottle 2 is required before use, but the phenomenon of cell agglomeration cannot be eliminated, so the filter membrane is designed between the liquid suction port of the medicine injection module 5 and the connecting cover 10, which can reduce cell agglomeration and make cells evenly cover the wound.

[0078] As shown in Figure 9 The connecting cover 10 is provided with an internal thread, and the liquid suction port of the medicine injection module 5 is provided with an external thread.

[0082] Preparation stage:

[0083] Install the medicine bottle 2 containing medicine into the bottle groove 101 of the gun body 1, and ensure that the liquid suction port of the medicine injection module 5 communicates with the medicine bottle 2.

[0084] Wound recognition and positioning:

[0085] The operator holds the gun body hand holding part 103, and aims the infrared scanning head 6 at the wound area of the patient.

[0086] The infrared scanning head 6 scans the wound and forms an image, which is fed back to the image analysis unit of the control panel 9, which automatically calculates the area and shape of the wound.

[0087] If necessary, the identified area is manually revised through the display screen of the control panel 9 to ensure accurate positioning.

[0088] Dynamic adjustment of the spray head:

[0089] Direction adjustment (drive member one 7): the motor 703 drives the rotating ring 701 to rotate forward or backward, which, through the cooperation of the slider 702 and the arc groove 301 of the ball seat 3, drives the spray head 4 to rotate around the axis of the rotating ring 701, covering the wound in the horizontal direction.

[0090] Angle adjustment (drive member two 8): the electric push rod 805 pushes the push-pull block 801, which, through the connecting rod 804, presses the bent rod 803, changes the inclination angle of the ball seat 3, and adjusts the coverage range of the spray head 4 in the vertical direction.

[0091] Intelligent local drug delivery:

[0092] Press the button 18, and the drug delivery module 5 starts to extract the drug solution and deliver it to the spray head 4 through the flow guide pipe 501.

[0093] Under the cooperative control of the motor 703 and the electric push rod 805, the spray head 4 dynamically rotates and tilts according to the preset path, ensuring that the drug solution uniformly covers the entire area of the wound.

[0094] The control panel 9 monitors the status of local drug delivery in real time and adjusts the rate and range of local drug delivery according to the wound area.

[0095] Completion and maintenance:

[0096] After the treatment is completed, loosen the button 18, and the drug delivery module 5 automatically stops working. Turn off the power, reset the control panel 9 to the side wall of the gun body 1, and close the dust cover 17 to keep the equipment clean. Charge the battery 16 through the charging port 1601 to ensure that the equipment is always in standby state. This device is not only easy to operate, but also easy to carry, and can immediately and efficiently treat sudden wounds without relying on medical institutions, providing great convenience for users.
