Technical Field
[0001] The utility model relates to the field of medical equipment, in particular to a balloon expansion pressure pump sleeve oil spraying device. Background Art
[0002] Balloon inflation pumps are critical instruments in interventional medical procedures, used to precisely control the inflation and deflation of balloon catheters. They are widely used in cardiovascular intervention, neurointervention, urology, and other fields. Their core component, the sleeve, requires silicone oil lubrication to reduce friction, ensure stable pressure transmission, and extend the life of the device. In the manufacturing process of balloon inflation pumps, spray-on silicone oil plays a vital role as a lubricant and sealant, helping to reduce mechanical friction, improve device sealing, and extend the life of the device.
[0003] Currently, in the process of manufacturing balloon pressure pumps, a slidable piston (or push rod) is usually inserted into a sleeve (a tubular cavity with a smooth inner wall). By pushing / pulling the piston to compress or release the liquid in the cavity, mechanical force is converted into liquid pressure. Silicone oil then needs to be manually applied to the sleeve as a lubricant and sealant.
[0004] However, the manual silicone oil application process has problems such as uneven application, difficult to control the amount of silicone oil used, and low application efficiency, which makes it impossible to guarantee product quality and affects the reliability and safety of the balloon expansion pressure pump. At the same time, excessive spraying of silicone oil may also cause contamination of the balloon expansion pressure pump and even affect its clinical safety. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a balloon expansion pressure pump sleeve oil spraying device, which aims to solve the problems of uneven application, difficult control of silicone oil dosage, low application efficiency, etc. in the current manual silicone oil application process, which leads to the inability to guarantee product quality and affects the reliability and safety of the balloon expansion pressure pump.

[0009] The control mechanism adjusts the rate at which compressed air enters the silicone oil barrel according to the pressure display, and drives the oil spraying member to align with the sleeve through the adjustment mechanism, so as to accurately spray the atomized silicone oil into the sleeve.
[0010] According to one aspect of the above technical solution, the support mechanism includes a support shell, a partition plate arranged in the support shell, and a horizontal plate arranged perpendicular to the partition plate, and the sleeve is arranged on the horizontal plate.
[0011] According to one aspect of the above technical solution, a slot is provided on the transverse plate, and the slot faces the oil spraying component.
[0012] According to one aspect of the above technical solution, the control mechanism includes a first regulating valve, a second regulating valve, and a filter pressure regulating valve arranged on the supporting shell, the first regulating valve is respectively connected to the filter pressure regulating valve and the silicone oil barrel, and the second regulating valve is respectively connected to the filter pressure regulating valve and the oil injection component.

[0027] See also Figures 1-4 , shown is a schematic structural diagram of a balloon expansion pressure pump sleeve 500 oil spraying device provided in one embodiment of the present invention, the balloon expansion pressure pump sleeve 500 oil spraying device includes a support mechanism 100, a control mechanism 200 provided on the support mechanism 100, a spraying mechanism 300, and an adjustment mechanism 400, wherein:
[0028] To replace manual application of silicone oil, the spray mechanism 300 includes a silicone oil barrel 320 mounted on the support mechanism 100, and an oil sprayer 310 in communication with the silicone oil barrel 320. The oil sprayer 310 is movably connected to the adjustment mechanism 400. The control mechanism 200 adjusts the rate at which compressed air enters the silicone oil barrel 320 based on the pressure display. The oil sprayer 310 adjusts the angle and height of its connection with the adjustment mechanism 400 so that the oil sprayer 310 faces the sleeve 500, accurately spraying the atomized silicone oil into the sleeve 500.
[0029] Furthermore, the support mechanism 100 includes a support housing 110, a partition 120 disposed within the support housing 110, and a horizontal plate 130 disposed perpendicular to the partition 120. The sleeve 500 is mounted on the horizontal plate 130. The partition 120 divides the support housing 110 into an oil spraying area and an internal area. The silicone oil tank 320 and the transmission pipeline are located in the internal area. The control mechanism 200, the spraying mechanism 300, and the adjustment mechanism 400 are located in the oil spraying area. Furthermore, a transparent baffle is provided on the support housing 110 for observing the oil spraying process of the internal oil spraying element 310.
[0030] In addition, the transverse plate 130 is vertically arranged on the partition plate 120 , and a slot 131 is provided on the transverse plate 130 . The sleeve 500 moves along the slot 131 until it is located directly below the oil spraying member 310 . It is worth noting that a compression mechanism 600 is also provided below the horizontal plate 130. The compression mechanism 600 includes a fixed seat 610 provided on the partition 120, a push rod 620 passed through the fixed seat 610, and an elastic member 630 sleeved on the push rod 620. The two ends of the elastic member 630 are respectively abutted between the fixed seat 610 and the end of the push rod 620. When the control sleeve 500 moves along the slot 131, the push rod 620 and the elastic member 630 are compressed to move the sleeve 500 to the bottom of the injection part 310, press the sleeve 500 to maintain the current posture, and make the opening of the sleeve 500 face the injection port of the injection part 310 until the injection process is completed and the sleeve 500 is taken out along the slot 131.
[0031] To adjust the position of the fuel injection element 310, the adjustment mechanism 400 includes an adjustment bracket 410 mounted on the partition 120 and an adjustment roller 420 mounted on the adjustment bracket 410. The fuel injection element 310 is mounted on the adjustment roller 420. The adjustment bracket 410 is an L-shaped bracket, one end of which is connected to the partition 120 and the other end is used to pass through the adjustment roller 420. One end of the adjustment roller 420 is inserted into the adjustment bracket 410 and the other end is inserted into the fuel injection element 310, allowing the fuel injection element 310 to rotate freely, thereby adjusting the angle of the fuel injection element 310. It is worth noting that in this embodiment, the connection between the adjustment roller 420, the adjustment bracket 410, and the fuel injection element 310 can be an interference fit, so that the fuel injection element 310 can be directly rotated to a preset angle. Alternatively, a locking member can be installed on the oil sprayer 310, perpendicular to the adjustment roller 420. After the angle of the oil sprayer 310 is adjusted, the adjustment roller 420 and the oil sprayer 310 are locked to fix the current angle of the oil sprayer 310. Several mounting holes are provided on the partition 120, and the height of the oil sprayer 310 can be adjusted by adjusting the height of the adjustment bracket 410. Furthermore, the oil sprayer 310 and the silicone oil tank 320 are connected by several transmission pipes, through which the silicone oil tank 320 transfers silicone oil to the oil sprayer 310.
[0032] In this application, a control mechanism 200 controls the delivery speed of silicone oil and the rate at which compressed air enters the oil spray element 310, so that the silicone oil combines with the compressed air within the oil spray element 310 to form atomized silicone oil, which is then sprayed into the sleeve 500. The control mechanism 200 includes a first regulating valve 210, a second regulating valve 220, and a filter pressure regulating valve 230, which are disposed on the support housing 110. The first regulating valve 210 connects the filter pressure regulating valve 230 to the silicone oil tank 320, and the second regulating valve 220 connects the filter pressure regulating valve 230 to the oil spray element 310. The oil spray element 310 is provided with a first connection port 311 and a second connection port 312. The first connection port 311 is connected to the silicone oil tank 320 via a delivery pipe, and the second connection port 312 is connected to the second regulating valve 220 via a delivery pipe. A first pressure gauge 240 and a second pressure gauge 250 are provided on the partition 120 to display the pressure within the silicone oil tank 320 and the pressure within the oil spray element 310, respectively.
[0033] The filter pressure regulating valve 230 can simultaneously filter impurities in the external gas while regulating the pressure of the external gas entering the oil spraying device of the present application, and the filtered compressed gas is regulated by the second regulating valve 220 so that the pressure of the compressed gas entering the oil spraying part 310 reaches a preset value. Similarly, the first regulating valve 210 also controls the pressure of the compressed gas entering the silicone oil passage, so that the rate of silicone oil flowing into the oil spraying part 310 through the transmission pipeline is coordinated with the compressed gas entering the silicone oil passage to achieve the desired spraying effect and avoid the phenomenon of silicone oil clumping. In addition, the pressure of the compressed gas in the silicone oil barrel 320 and the pressure of the compressed gas entering the oil spraying part 310 can be displayed by the first pressure gauge 240 and the second pressure gauge 250.
[0034] Furthermore, a time relay 111 is provided on the support housing 110, and a position sensor 510 is provided on the sleeve 500. The time relay 111 controls the opening and closing of the filter-pressure regulating valve 230, thereby controlling the spraying time of the atomized silicone oil. Simultaneously, the position sensor 510 on the sleeve 500 detects when the sleeve 500 is in place and generates a position signal. This position signal then controls the opening of the filter-pressure regulating valve 230 to spray the atomized silicone oil.
[0035] In summary, the balloon expansion pressure pump sleeve oil spray device proposed by the present invention uses a filter pressure regulating valve to filter external air, and displays the pressure inside the silicone oil barrel and the oil spray element via a first pressure gauge and a second pressure gauge. This allows silicone oil and compressed gas to enter the oil spray element simultaneously, thereby atomizing the silicone oil. The atomized silicone oil is then sprayed into the sleeve, reducing friction within the moving parts of the balloon expansion pressure pump and extending the service life of the balloon expansion pressure pump. By using the oil spray element to spray instead of manually applying silicone oil, the present invention ensures the amount of silicone oil used in the sleeve, and the coating is uniform, preventing the silicone oil from clumping, and ensuring that the amount of silicone oil inside the balloon expansion pressure pump is appropriate and of qualified quality.
