When in use, hold the hand-held column 102 tightly, and push the medicine pushing rod 106 and the piston 105 forward through the push plate 108, so that the liquid medicine in the medicine application tube 101 is sprayed onto the patient through the medicine spraying head 103. And when adding medicine midway, medicine can be added through the medicine adding interface 107. The added liquid medicine enters the medicine application tube 101 through the medicine pushing rod 106 and the one-way valve 104 provided in the piston 105. Adding medicine is more convenient, avoiding multiple operations of the speculum 2 for adding medicine, reducing secondary injuries, and making it more convenient and fast for patients to apply medicine.

[0021] Refer to Figure 1 and Figure 3 , the adjusting rod 210 and the second hand-held handle 212 and the first hand-held handle 209 are all connected by socketing. The rotating shaft 205 and the adjusting grooves 204 at the lower parts of the second hand-held handle 212 and the first hand-held handle 209 are connected by socketing and limited by nuts. Before applying medicine, operate through the speculum 2, and then put the medicine application assembly 1 into the patient's body through the speculum 2. And the medicine application assembly 1 and the speculum 2 are limited and supported through the insertion interface 202 and the support frame 208, making the placement of the medicine application assembly 1 more stable and facilitating the medical staff to operate the speculum 2 and the medicine application assembly 1 simultaneously.

[0022] Working principle: The adjusting rod 210 of the jet medicine application device is sleeved and connected with the second handle 212 and the first handle 209. The rotating shaft 205 is sleeved and connected with the adjusting groove 204 at the lower part of the second handle 212 and the first handle 209 and is limited by a nut. Before medicine application, an operation is carried out through the speculum 2, and then the medicine application component 1 is put into the patient's body through the speculum 2. The medicine application component 1 and the speculum 2 are limited and supported by the insertion interface 202 and the support frame 208, making the placement of the medicine application component 1 more stable and facilitating the medical staff to operate the speculum 2 and the medicine application component 1 simultaneously. The one-way valve 104 and the piston 105 are screwed and connected by threads. The piston 105 and the medicine application tube 101 are sleeved and connected. The medicine adding interface 107 and the one-way valve 104 are in a connected structure. The insertion interface 202 on the lower blade 201 and the upper blade 203 and the medicine application tube 101 are sleeved and connected. The locking screw 207 is sleeved and connected with the mounting plate 206 and the support frame 208 and is limited by a nut. The support frame 208 and the medicine application tube 101 are connected by clamping. When in use, hold the holding column 102 tightly, push the medicine pushing rod 106 and the piston 105 forward through the push plate 108, so that the liquid medicine in the medicine application tube 101 is sprayed onto the patient through the medicine spraying head 103. And when adding medicine in the middle, medicine can be added through the medicine adding interface 107. The added liquid medicine enters the medicine application tube 101 through the medicine pushing rod 106 and the one-way valve 104 arranged in the piston 105. Medicine adding is more convenient, avoiding multiple operations of the speculum 2 for medicine adding and reducing secondary injury, making it more convenient and fast for the patient to apply medicine.
