Detailed Description
Referring to fig. 1, the hemostatic powder delivery tube comprises a gas generator 1, a front-end inflatable hemostatic ring 2, a rear-end inflatable hemostatic ring 3, an inflatable catheter 4 and a hemostatic powder delivery tube 5, wherein the gas generator 1 is respectively connected with the front-end inflatable hemostatic ring 2 and the rear-end inflatable hemostatic ring 3 through the inflatable catheter 4, and one end of the hemostatic powder delivery tube 5 is connected with a hemostatic package 104 in the gas generator 1.
Referring to fig. 2, the gas generator 1 comprises a shell 101, a compressed gas cylinder 102, a control valve body 103, a hemostatic bag 104, a control valve core 105, a spring 106, an inflation port 107, a hemostatic powder conveying port 108 and a pressure adjusting nut 109, wherein the exhaust hole of the compressed gas cylinder 102 is in threaded connection with the air inlet hole of the control valve body 103, the control valve core 105 is inserted into the control valve body 103 through the spring 106 and the pressure adjusting nut 109, the spring 106 is sleeved outside the control valve core 105 to prevent the control valve core from sliding randomly, the pressure adjusting nut 19 is connected with the shell 101 through threads and controls the valve body 103 and compresses the spring 106, one end of the inflation port 107 is in threaded connection with the exhaust hole at the lower part of the control valve body 103, the other end is used for connecting with the inflation channel 4, the hemostatic bag 104 is fixedly installed on the shell 101 and is communicated with the exhaust hole at the upper part of the control valve body 103, and the hemostatic powder conveying port 108 is connected with the hemostatic powder conveying pipe 5;
the bottom of the control valve core 105 is provided with an air inlet and an air outlet, and a through hole at the bottom of the control valve core 105 is communicated with an air passage in the middle of the air inlet and the air outlet.
Principle of operation
When the limb needs to be quickly and emergently stopped, referring to fig. 5, if the forearm portion needs to be stopped, the front end inflatable hemostatic ring 2 and the rear end inflatable hemostatic ring 3 are sleeved on the wrist joint and the elbow joint respectively; if the upper arm part needs to stop bleeding, the front end inflatable hemostatic ring 2 and the rear end inflatable hemostatic ring 3 are respectively sleeved on the elbow joint and the shoulder joint; if the lower leg part needs to stop bleeding, the front end inflatable hemostatic ring 2 and the rear end inflatable hemostatic ring 3 are respectively sleeved on the ankle joint and the knee joint; if the thigh part needs to stop bleeding, the front end inflatable hemostatic ring 2 and the rear end inflatable hemostatic ring 3 are respectively sleeved on the knee joint and the hip joint.
Referring to fig. 3, after the control valve core 105 is pulled upwards, the control valve core 105 slides upwards, the spring 106 is compressed, and the air inlet and the air outlet at the bottom of the control valve core 105 are communicated, so that compressed air in the compressed air bottle 102 is allowed to flow through the air inlet and the air outlet at the bottom of the control valve core 105, and enters the air charging port 107, and finally the front-end inflatable hemostatic ring 2 and the rear-end inflatable hemostatic ring 3 are rapidly inflated, so that the front-end inflatable hemostatic ring and the rear-end inflatable hemostatic ring are inflated to generate compression force to compress arterial blood vessels at joints, a hemostatic effect is achieved, and a rapid compression hemostatic function of limbs is achieved.
Referring to fig. 4, the small hole at the bottom of the control valve core 105 drains the inflation pressure to the bottom of the control valve core 105, so as to generate upward thrust, the magnitude of the thrust is in a proportional relation with the inflation pressure, when the thrust exceeds the pressure of the spring 106, the control valve core 105 continues to slide upwards, the air inlet hole and the air outlet hole at the upper part of the control valve body 103 are communicated through the control valve core 105, compressed gas in the compressed gas cylinder 102 enters the hemostatic package 104, and hemostatic powder in the compressed gas cylinder is sprayed to a wound through the hemostatic powder conveying port 108 and the hemostatic powder conveying pipe 5, so that the hemostatic effect is enhanced.
Further, the pressure adjusting nut 109 in the gas generator 1 may be used to adjust the inflation pressure, and when the inflation pressure is insufficient, rotating the pressure adjusting nut 109 clockwise may increase the pressure of the spring 106, so that the balance force of the control valve element 105 is increased, thereby increasing the force of compression hemostasis by the inflation pressure; conversely, rotating the pressure adjustment nut 109 counterclockwise may reduce the inflation pressure and reduce the force of hemostasis by compression.
Furthermore, grooves are formed in the positions of the air inlet and the air outlet of the hemostatic package 104, so that sealing of hemostatic powder is kept during normal storage, and when the air pressure reaches a certain value, the grooves are broken by air, and the hemostatic powder in the grooves can be sprayed out.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the invention in any way, but any simple modification, equivalent variation and modification of the above embodiments according to the technical principles of the present invention are within the scope of the technical solutions of the present invention.
