Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a pressure bag. Background Art

[0002] During the cystoscopy procedure for patients, doctors often encounter problems such as bladder bleeding or cloudy urine in the bladder, which affect the inspection field of view. To ensure a clear view of the bladder cavity, a large amount of normal saline is required for flushing. Therefore, a pressure bag is needed to pressurize the infusion bag to increase its injection speed.

[0003] Currently, the pressure bags on the market are designed such that the infusion bag is placed in the sandwich layer of the infusion pressure bag, and then the infusion pressure bag is hung on the infusion fixing rack for pressurized infusion. However, it is inconvenient to replace the infusion bag. Moreover, the existing pressure bags require manual pressing of the balloon for pressurization. In the case of using several bags of normal saline during cystoscopy for patients, the hand will feel extremely fatigued due to continuous pressing, increasing the burden on medical staff. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pressure bag that is convenient for replacing the infusion bag and reduces the burden on medical staff.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A pressure bag includes a cuff. The outer surface of one side of the cuff is provided with a hook surface of Velcro, and the outer surface of the other side of the cuff is provided with a loop surface of Velcro. An airbag is arranged inside the cuff. The outer surface of the cuff is connected with an inflation tube, and the inflation tube is connected with the airbag. The end of the inflation tube is provided with a compression type inflation cylinder. The first side plate and the second side plate are respectively installed on the two side surfaces of the compression type inflation cylinder. An air outlet pipe and an air inlet pipe are respectively installed on the two side surfaces of the compression type inflation cylinder, and the air outlet pipe is connected with the inflation tube. One-way valves are arranged inside the air outlet pipe and the air inlet pipe. An installation plate is arranged on the lower side of the compression type inflation cylinder, and a reciprocating mechanism capable of making the compression type inflation cylinder reciprocate and stretch is arranged inside the installation plate.

[0007] Thus, after hanging the infusion bag on the infusion rack, it only needs to tie the cuff on the infusion bag to complete the installation. Subsequently, the reciprocating mechanism drives the compression type inflation cylinder to reciprocate and stretch, thereby achieving the purpose of automatically inflating the airbag inside the cuff. There is no need for manual extrusion, reducing the burden on medical staff and avoiding hand fatigue. Moreover, the extrusion effect on the infusion bag is stable, ensuring the continuous and stable delivery of normal saline, with better use effect. And when replacing the infusion bag, as long as the infusion bag is hung on the infusion rack in advance, and then the cuff is torn off and tied on the replaced infusion bag, pressurized liquid supply can be carried out, which is convenient for replacement.

[0008] Further, the reciprocating mechanism includes an installation groove formed on the upper surface of the mounting plate. A reciprocating lead screw is rotatably installed inside the installation groove. A slider is installed on the outer surface of the reciprocating lead screw, and the end of the slider is connected to the second side plate. A fixed block is installed on the upper surface of the mounting plate, and the end of the fixed block is connected to the first side plate. A motor is installed on the side surface of the mounting plate, and the output shaft of the motor is connected to the reciprocating lead screw.

[0009] When the motor is started, its output shaft drives the reciprocating lead screw to rotate, thereby driving the slider to reciprocate along the length direction of the reciprocating lead screw and driving the second side plate to reciprocate. Since the first side plate is fixedly installed on the upper surface of the mounting plate, the reciprocating telescopic movement of the compression type air pump can be realized to inflate the airbag inside the cuff.

[0010] Further, an outer cover is installed on the side surface of the mounting plate, and the outer cover is arranged outside the motor. A button is arranged on the outer surface of the outer cover, and the button is electrically connected to the motor.

[0011] Through the arrangement of the outer cover, the motor can be protected, and through the arrangement of the button, it is convenient to control the motor.

[0012] Further, a lithium battery is arranged inside the outer cover, and a charging hole is arranged on the outer surface of the outer cover.

[0013] Through the arrangement of the lithium battery, power support can be provided for the motor, so that there is no need to connect a power cord during use, improving the portability of use.

[0014] Further, two parallel slide bars are installed inside the installation groove, and the slider is slidably installed on the outer surfaces of the two slide bars.

[0015] Through the arrangement of the slide bars, a limiting effect can be achieved on the slider, making the slider move more smoothly during the movement process.

[0016] Further, a handle is installed on the lower surface of the mounting plate, and a rubber pad is arranged on the outer surface of the handle.

[0017] Through the arrangement of the handle, it is convenient to take the mounting plate during use. And through the arrangement of the rubber pad, the hand pressure can be relieved, the comfort level can be improved, and the friction with the hand can be enhanced to avoid the situation of hand slipping.

Specific embodiments

[0023] The present utility model will be described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a pressurizing bag includes a cuff 100. A rough side of the Velcro 101 is provided on an outer surface of one side of the cuff 100, and a prickly side of the Velcro 102 is provided on an outer surface of the other side of the cuff 100. An airbag is provided inside the cuff 100. An inflatable tube 103 is connected to an outer surface of the cuff 100, and the inflatable tube 103 is connected to the airbag. A compression inflator 104 is provided at an end of the inflatable tube 103. A first side plate 105 and a second side plate 106 are respectively mounted on two side surfaces of the compression inflator 104. An outlet pipe 107 and an inlet pipe 108 are respectively mounted on two side surfaces of the compression inflator 104, and the outlet pipe 107 is connected to the inflatable tube 103. Check valves are provided inside both the outlet pipe 107 and the inlet pipe 108. A mounting plate 109 is provided below the compression inflator 104, and a reciprocating mechanism 200 capable of reciprocatingly telescoping the compression inflator 104 is provided inside the mounting plate 109.

[0025] During use, first hang the normal saline infusion bag on the infusion stand, then tie the cuff 100 on the infusion bag and fix it using the hook-and-loop fastener's fuzzy surface 101 and prickly surface 102. Subsequently, drive the compression air pump 104 to reciprocate and stretch through the reciprocating mechanism 200. Due to the setting of the one-way valves inside the air outlet pipe 107 and the air inlet pipe 108, when the compression air pump 104 compresses, the air inside it can be injected into the airbag inside the cuff 100 through the air filling pipe 103. When the compression air pump 104 stretches, the external air can enter the compression air pump 104 from the air inlet pipe 108. Therefore, during the reciprocating movement of the compression air pump 104, the airbag can be continuously inflated and expanded, causing the cuff 100 to squeeze the infusion bag inside it, thereby accelerating the injection speed of the normal saline. When replacing the infusion bag, as long as the infusion bag is hung on the infusion stand in advance, then tear off the cuff 100 and tie it on the replaced infusion bag to perform pressurized liquid supply, which is convenient for replacement.

[0026] Specifically, the reciprocating mechanism 200 includes an installation groove 201 opened on the upper surface of the mounting plate 109. A reciprocating lead screw 202 is rotatably installed inside the installation groove 201. A slider 203 is installed on the outer surface of the reciprocating lead screw 202, and the end of the slider 203 is connected to the second side plate 106. A fixed block 205 is installed on the upper surface of the mounting plate 109, and the end of the fixed block 205 is connected to the first side plate 105. A motor 204 is installed on the side surface of the mounting plate 109, and the output shaft of the motor 204 is connected to the reciprocating lead screw 202. When the motor 204 is started, its output shaft drives the reciprocating lead screw 202 to rotate, thereby driving the slider 203 to reciprocate along the length direction of the reciprocating lead screw 202 and driving the second side plate 106 to reciprocate. Since the first side plate 105 is fixedly installed on the upper surface of the mounting plate 109, the reciprocating stretching of the compression air pump 104 can be realized to inflate the airbag inside the cuff 100.

[0027] Specifically, an outer cover 300 is installed on the side surface of the mounting plate 109, and the outer cover 300 is arranged outside the motor 204. A button 301 is arranged on the outer surface of the outer cover 300, and the button 301 is electrically connected to the motor 204. Through the setting of the outer cover 300, the motor 204 can be protected, and through the setting of the button 301, it is convenient to control the motor 204.

[0028] Specifically, a lithium battery 400 is arranged inside the outer cover 300, and a charging hole 401 is arranged on the outer surface of the outer cover 300. Through the setting of the lithium battery 400, power support can be provided for the motor 204, and thus there is no need to connect a power cord during use, improving the portability of use.

[0029] Specifically, two mutually parallel sliding rods 500 are installed inside the installation groove 201, and the slider 203 is slidably installed on the outer surfaces of the two sliding rods 500. Through the arrangement of the sliding rods 500, the slider 203 can be limited, making the slider 203 move more smoothly and steadily during the movement process.

[0030] Specifically, a grip 600 is installed on the lower surface of the mounting plate 109, and a rubber pad is arranged on the outer surface of the grip 600. Through the arrangement of the grip 600, it is convenient to take the mounting plate 109 during use. Moreover, the arrangement of the rubber pad can relieve the hand pressure, improve the comfort, and enhance the friction with the hand to avoid the situation of hand slipping.

It cannot be determined that the specific implementation manners of the present utility model are only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present utility model.
