DETAILED DESCRIPTION
[0018] The spray type bladder instillation device of the present invention will be described below with reference to the accompanying drawings.
[0019] In the embodiments of the present application, Figures 1 to 3 As shown, the spraying type bladder instillation device (hereinafter referred to as "the present invention") comprises a solid latex head 1, an instillation tube body 2, a medicine liquid spraying bag 3, a medicine liquid latex membrane 3-1, a flap-type distribution hole 3-2, an air bag 4, an air guide tube 5, an air guide tube pagoda joint 6, a medicine liquid catheter 7, a medicine liquid catheter pagoda joint 8, and a medicine liquid catheter passage 9. The air bag 4 is provided near the end of the inner side of the instillation tube body 2, and the medicine liquid spraying bag 3 is sleeved on the outer side of the instillation tube body 2, and the medicine liquid spraying bag 3 has the medicine liquid built in it. cavity, a solid latex head 1 is fixedly installed at the end of the perfusion tube body 2, the airway tube pagoda joint 6 at the rear end of the perfusion tube body 2 is connected to the air bag 4 through the preset airway tube 5 inside the perfusion tube body 2, the medicine liquid catheter pagoda joint 8 is connected to the side of the perfusion tube body 2 through the medicine liquid catheter 7, the medicine liquid catheter 7 is connected to one end of the medicine liquid catheter passage 9, and the other end of the medicine liquid catheter passage 9 is connected to the medicine liquid cavity of the medicine liquid spraying bag 3, and the outer surface of the medicine liquid latex membrane 3-1 of the medicine liquid spraying bag 3 is evenly distributed with valve-type distribution holes 3-2.
[0020] In order to further optimize the working efficiency of the present application and enable the medicine spray capsule 3 to enter the urethra more smoothly, the solid latex head 1 is connected to the medicine spray capsule 3, and the outer surface has a smooth transition. If the solid latex head 1 and the medicine spray capsule 3 are not smoothly connected, the patient will feel a foreign body or pain. In order to prevent the medicine from flowing back and increase the pressure during drug spraying, so that the liquid and gas merge and the contact surface with the bladder mucosa is increased, the valve-type distribution hole 3-2 is conical, with the wider end facing the inner side of the medicine latex membrane 3-1 and the narrower end facing the outer side of the medicine latex membrane 3-1. The length of the solid latex head 1 is not less than two centimeters. In order to achieve the clinical dosage, the medicine cavity capacity of the medicine spray capsule 3 is 50 to 80 milliliters. In order to prevent the medicine from leaking back, such as Figure 5 As shown, the airway tube pagoda connector 6 and the drug solution catheter pagoda connector 8 have the same structure.
[0021] When in use, install the spray-type bladder instillation device and connect the corresponding pipeline equipment and it can be put into use.
[0022] When the present invention is used, the specific operation is as follows:
[0023] When in use, connect the airway tube pagoda connector 6 through a syringe, and let the medicine liquid enter the medicine liquid cavity of the medicine liquid spray bag 3 through the medicine liquid catheter pagoda connector 8 along the medicine liquid catheter 7 and the medicine liquid catheter passage 9, then apply lubricating liquid on the solid latex head 1, the perfusion tube body 2 and the medicine liquid spray bag 3, and send the solid latex head 1 and the medicine liquid spray bag 3 from the urethra through the perfusion tube body 2, and then push the syringe filled with air inside to send air into the air bag 4 through the airway tube 5. The air bag 4 expands and props up the medicine liquid spray bag 3. As the medicine liquid spray bag 3 is opened, the valve-type distribution hole 3-2 pushes the medicine liquid in the medicine liquid cavity of the medicine liquid spray bag 3 under the pressure of the air bag 4, and the narrower port of the valve-type distribution hole 3-2 is opened. Figure 4 As shown, the medicine in the medicine cavity is sprayed from the valve-type distribution hole 3-2 to the inner wall of the bladder under the pressure of the air bag 4, thereby completing the infusion. After the infusion is completed, the syringe injects 10 ml of gas to prompt all the medicine in the infusion device to enter the bladder. Finally, the air in the air bag 4 is exhausted, and the medicine spray bag 3 will return to its original state under the action of its own elastic force. At this time, the medicine spray bag 3 can be removed from the patient's urethra through the infusion tube body 2.
[0024] In summary, the spray-type bladder instillation device of the embodiment of the present invention, by adding an inflatable air bag 4 to expand the external sleeve of the instillation tube body 2 to connect the liquid medicine spray bag 3, enables the liquid medicine spray bag 3 to spray the liquid medicine into the bladder, and in addition, with the help of the pagoda joint, the chemotherapy drugs are prevented from spilling, thereby avoiding drug waste and also avoiding chemotherapy drug pollution. By injecting air to increase pressure, the drug can be formed into a spray through the conical flap-type distribution hole 3-2, and the gas-liquid blending increases the contact surface with the bladder mucosa, effectively achieving the purpose of treatment. And after the drug injection is completed, a certain amount of gas is injected again, so that all the drugs in the instillation device can reach the bladder, so as to maximize the drug treatment effect.
