One side of the compression unit 20 is adjacent to the filtering unit 120 and communicates with the filtering unit 120, and the other side of the compression unit 20 is adjacent to the path switching unit 60 and communicates with the path switching unit 60, The compression unit 20 may be, for example, an air compressor. In the embodiment of the present invention, the overpressure protection unit 30 , the pressure detection unit 40 , the flow detection unit 50 and the third unit are further disposed between the compression unit 20 and the path switching unit 60 in sequence. to valve 90. The overpressure protection unit 30 may be, for example, a pressure reducing valve, and the pressure detection unit 40 and the flow detection unit 50 may be, for example, a pressure gauge and a flowmeter, respectively.

The path switching unit 60 is adjacent to the delivery tube 110 and the medicine tube 100 and communicates with the delivery tube 110 and the medicine tube 100 . The medicine tube 100 is also adjacent to the delivery tube 110 and communicates with the delivery tube 110 . The delivery tube 110 Then the chamber A of the human body is connected, and a medicine with a hemostatic function is stored in the medicine tube 100. For example, the medicine tube 100 is a structure such as a syringe that can push the medicine, and the medicine can be liquid or powder, etc. , the present invention is not limited. More specifically, one end of the delivery tube 110 includes a three-way valve, the path switching unit 60 has a first outlet 601 and a second outlet 602 , and one end of the drug tube 100 is connected to the first outlet of the path switching unit 60 . An outlet 601, the other end of the drug tube 100 is connected to the first end of the three-way valve, the second outlet 602 of the path switching unit 60 is connected to the second end of the three-way valve, and the third end of the three-way valve Then it is connected to the chamber A. In the embodiment of the present invention, between the first outlet 601 of the path switching unit 60 and the drug tube 100, the filter unit 120 and the first one-way valve 70 are further provided; in the path switching unit Between the second outlet 602 of the 60 and the conveying pipe 110, the filter unit 120 and the second one-way valve 80 are also arranged.

Please refer to the first and second figures. Before using the medicine propelling device for treating wounds in the inner chamber, first operate the control unit 10 to open the compression unit 20, so that a gas filtered by the filter unit 120 enters the The compression unit 20 is compressed, and the compressed gas is then continuously output to the path switching through the overpressure protection unit 30 , the pressure detection unit 40 , the flow detection unit 50 and the third one-way valve 90 in sequence unit 60.

Please refer to the second figure and the third figure in conjunction with the first figure. When the compressed gas passes through the overpressure protection unit 30, if the pressure of the gas exceeds an upper limit of the overpressure protection unit 30, for example 14psi, the overpressure protection unit 30 will directly remove the excess gas, so as to ensure the normal operation of the medicine propelling device for treating the wound in the inner chamber. After the pressure of the gas is lower than the upper limit, the gas will enter the pressure detection unit 40 and the flow detection unit 50 in sequence. The pressure detection unit 40 and the flow detection unit 50 respectively detect a detection value of the gas, and send the detection value to the control unit 10 for comparison with a pre-stored threshold value. When the detected value exceeds the threshold, the control unit 10 will control the prompting unit 130 to issue a prompt to remind a medical staff to pay attention. It should be added that the detection value of the pressure detection unit 40 is the pressure of the gas, the detection value of the flow detection unit 50 is the flow rate of the gas, and the threshold value includes the threshold value of the pressure and the flow rate The threshold value of the pressure detection unit 40 is compared with the threshold value of the pressure, and the detection value of the flow detection unit 50 is compared with the threshold value of the flow rate.

After the gas passes through the third one-way valve 90 to the path switching unit 60, the control unit 10 then controls the path switching unit 60 to transfer the compressed gas from the first path switching unit 60 according to the operation of the medical staff or system presets The outlet 601 or the second outlet 602 is sent to the delivery pipe 110 to maintain the positive pressure of the delivery pipe 110 .

Please refer to the first and fourth figures, the control unit 10 has a first mode, so that the control unit 10 controls the path switching unit 60 to select to send the compressed gas to the first outlet 601 .

In the first mode, after the gas leaves the path switching unit 60 from the first outlet 601 , it is filtered again by the filter unit 120 , and then enters the drug tube 100 through the first one-way valve 70 . Since the gas has been compressed in the compression unit 20, the gas can push the drug in the drug tube 100 forward into the delivery tube 110, and the gas continues to enter the drug from the first outlet 601 The tube 100 pushes the medicament so that the medicament will continue to be propelled into the chamber A by the gas, and the delivery tube 110 maintains a positive pressure.

Please refer to Figure 1, Figure 3 and Figure 4. In the first mode, since the gas is to push the drug, the threshold value of the pressure of the gas can be, for example, 10 psi, when the detection value exceeds the threshold value , the control unit 10 will control the prompt unit 130 to issue the prompt.

Referring to the first and fifth figures, the control unit 10 also has a second mode, which enables the control unit 10 to control the path switching unit 60 to select to send the compressed gas to the second outlet 602 .

In the second mode, after the gas leaves the path switching unit 60 from the second outlet 602, it is filtered again through the filter unit 120, and then enters the conveying pipe 110 through the second one-way valve 80. The gas will also enter the chamber A at last, and the delivery pipe 110 still maintains a positive pressure. At this time, if there is the drug remaining in the first mode in the delivery tube 110, the gas will also push the drug to the chamber A together to prevent the drug from staying in the delivery tube 110 and contacting the chamber A Blockage caused by the body fluid in the .

Please refer to the first, third and fifth figures. In the second mode, since the gas mainly maintains the positive pressure of the conveying pipe 110, the threshold value of the pressure of the gas can be higher than that of the first mode. The threshold value of the mode is low, for example, between 1 psi and 2 psi. When the detection value exceeds the threshold value, the control unit 10 will also control the prompting unit 130 to issue the prompting. The prompts of the first mode and the second mode may be different, so that the medical staff can quickly find out the problem.

Referring to the first and sixth figures, the first mode and the second mode may be automatically switched by the control unit 10 by means of pulse width modulation. For example, the control unit 10 may be normally maintained in the first mode. In the second mode, the gas flows through the second outlet 602. When the medical staff determines that it is necessary to push the drug into the chamber A, the medical staff can press the The function activation button 101 enables the control unit 10 to switch between the first mode and the second mode by pulse width modulation several times, for example, three times, and then returns to the second mode. According to the needs of the medical staff, the duty cycle of the first mode and the second mode can be adjusted, that is, the working time of the control unit 10 in the first mode and the second mode can be adjusted, so as to maintain the While the delivery tube 110 is under positive pressure, the dosage of the medicament is controlled to ensure that the dosage of the medicament is sufficient to stop the bleeding of the chamber A, but will not affect the observation of the chamber A by the endoscope.

With the path switching unit 60, no matter whether the medicine is injected or not, the gas will be continuously fed into the delivery tube 110 to maintain the positive pressure of the delivery tube 110 and prevent the body fluid in the chamber A from penetrating into the delivery tube 110. As a result, the delivery tube 110 is blocked. And the first one-way valve 70, the second one-way valve 80 and the third one-way valve 90 can all ensure that the gas flows in one direction from the compression unit 20 to the conveying pipe 110, preventing the gas from flowing backwards. And the body fluid is sucked into the delivery tube 110 .
