Description

Technical Field

[0001] This utility model belongs to the technical field of medical pulse irrigators, and in particular, it is a leak detection device for the nozzle of a medical pulse irrigator. Background Technology

[0002] A medical pulse irrigator is an irrigator that simultaneously provides pulse irrigation and negative pressure suction. The nozzle is an essential component of the medical pulse irrigator. The nozzle is not only connected to the irrigating fluid but also to the negative pressure source. Therefore, the sealing performance of the nozzle directly affects the irrigating and negative pressure suction effects of the pulse irrigator. Chinese Patent No. CN206930414U discloses "a leakage detection device for a medical pulse irrigator nozzle, including a gas source for introducing gas into the waste liquid port of each pulse irrigator nozzle, a pressure gauge and control switch on the gas supply pipe for detecting the gas pressure in the gas supply pipe, a support bracket on the worktable for radially clamping each pulse irrigator nozzle, and movable sealing components and fixed components located on opposite sides of the support bracket for sealing the spray suction port and drug liquid port of each pulse irrigator nozzle respectively." The patent describes a system where a fixed sealing assembly is used. A support bracket clamps and positions the pulse jet nozzle radially, while a movable sealing assembly, controlled by a telescopic cylinder, clamps and seals the nozzle axially with the fixed sealing assembly, preventing nozzle twisting. The air inlet plug improves air intake sealing and enhances leak detection accuracy. Furthermore, the support bracket's clamping of the nozzle increases the stress on the nozzle's center. While this patent can clamp pulse jets used for sealing tests, the support bracket is not ideally suited to the shape of the pulse jet, hindering its ability to effectively limit the movement of pulse jets of varying lengths and shapes. This affects the pulse jet's stability, and the port positions of pulse jets of different sizes also vary, impacting the sealing effect. Utility Model Content

[0003] Purpose of the utility model: To provide a leakage detection device for the nozzle of a medical pulse irrigator, in order to solve the problem that the existing support brackets used for clamping are not well matched with the shape of the pulse irrigator, thus failing to provide good limiting operation for pulse irrigators of different lengths and shapes, which affects the stability of the pulse irrigator.

Detailed Implementation

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1-4 This utility model discloses a leakage detection device for a medical pulse irrigator nozzle, comprising a workbench 1, on which a support assembly 2, a fixed sealing assembly 4, and a movable sealing assembly 3 are arranged. The fixed sealing assembly 4 and the movable sealing assembly 3 are respectively located on both sides of the support assembly 2, and are used to perform sealing detection operations on the ports at both ends of the pulse irrigator nozzle 13 placed on the support assembly 2. The pulse irrigator nozzle 13 has a total of three ports, one of which is located at one end as the suction port 13-1, and the other two ports are located at the other end and are respectively the liquid medicine port 13-2 and the waste liquid port 13-3, which are distributed vertically. Figure 4 The positions of the various ports are shown. The fixed sealing assembly 4 seals the liquid medicine port 13-2 and the waste liquid port 13-3. The movable sealing assembly 3 seals the spray / suction port 13-1. The support assembly 2 includes a fixed base 6 and a movable base 7. The movable base 7 is located on one side of the fixed base 6 and close to the fixed sealing assembly 4. The movable base 7 is mounted on a horizontal moving member 10 via a height adjusting member 9. The horizontal moving member 10 is mounted on the worktable 1. The horizontal moving member 10 drives the movable base 7 to move horizontally along the worktable 1, changing the horizontal distance between the movable base 7 and the fixed base 6. The height adjusting member 9 adjusts the vertical distance between the movable base 7 and the worktable 1. The movable sealing assembly 3 includes a driving member and a component connected to the driving member. The moving rod 31 and the first sealing block 32 disposed on the moving rod 31 are provided. The driving member is disposed on the worktable 1 to drive the moving rod 31 to move horizontally along the worktable 1. The fixed sealing assembly 4 includes a fixed rod 41, an air inlet plug 42 disposed on the fixed rod 41 and a second sealing block 43. The bottom end of the fixed rod 41 is fixed on the worktable 1. The air inlet plug 42 is connected to an air source through an air pipe 421. The first sealing block 32, the air inlet plug 42 and the second sealing block 43 are each connected to an elastic displacement assembly 5. The first sealing block 32 is slidably disposed on the moving rod 31 through the elastic displacement assembly 5. The air inlet plug 42 and the second sealing block 43 are each slidably disposed on the fixed rod 41 through an elastic displacement assembly 5.

[0030] Both the fixed base 6 and the movable base 7 are provided with receiving grooves. The longitudinal section of the receiving groove is U-shaped, so that the pulse irrigator nozzle 13 can be placed in the receiving groove along the length of the workbench 1. The area of ​​the receiving groove in the movable base 7 is larger than the area of ​​the receiving groove in the fixed base 6. A clamping member 8 is provided in the receiving groove. The clamping member 8 is used to limit the pulse irrigator nozzle 13. The larger receiving groove in the movable base 7 makes it easier to place one end of the nozzle at both ends of the pulse irrigator nozzle 13 in it, which can better achieve the purpose of stable support.

[0031] The clamping member 8 includes at least two arc-shaped clamping plates 81 symmetrically arranged about the transverse centerline of the receiving groove. At least two support rods 82 are provided between the clamping plates 81 and the groove wall of the receiving groove. One end of each support rod 82 is hinged to the clamping plate 81, and the other end is hinged to a movable block 821. The movable block 821 is slidably connected to the groove wall of the receiving groove via a sliding member 822. The sliding member 822 includes a sliding slider mounted on the sliding block 821, which slides in a sliding groove formed in the groove wall. A clamping spring 83 is also connected between the groove wall of the receiving groove and the clamping plate 81. The clamping spring 83 is preferably located between the two support rods 82. The center position is connected to the tank wall, while the support rod 82 is symmetrically located on both sides of the clamping spring 83, which makes the balance of the clamping plate 81 better. When the pulse flush nozzle 13 is placed between the two clamping plates 81, the two clamping plates 81 move away in opposite directions. At this time, the support rod 82 is rotated by force, and the clamping spring 83 is also compressed. The moving block 821 is also pushed by the rotation of the support rod 82 and its position is adjusted by sliding the sliding member 822. While cooperating with the rotation of the support rod 82 to support it, it will not affect the stability of the support rod 82. The two clamping plates 81 can clamp and limit the pulse flush nozzle 13 on both sides under the action of the support rod 82 and the clamping spring 83, so that the pulse flush nozzle 13 is limited on the support assembly 2.

[0032] The height adjustment component 9 includes a height screw 91 and a height nut 92 that cooperates with the height screw 91. The height screw 91 is located parallel to one side of the fixed base 6 and is rotatably connected to the horizontal moving component 10. The height nut 92 is fixed to one side of the moving base 7, and a guide sleeve 94 is fixed to the other side of the moving base 7. The guide sleeve 94 is slidably sleeved on the guide rod 93, and the guide rod 93 is fixed on the horizontal moving component 10. When adjusting the height of the moving base 7 according to the actual height position of one end of the pulse flush nozzle 13, the height screw 91 is rotated first, so that the height nut 92 drives the moving base 7 to move along the height direction of the height screw 91. At this time, the guide sleeve 94 also slides up and down on the guide rod 93, which improves the moving stability of the moving base 7 and also enhances the support stability of the moving base 7.

[0033] The horizontal moving component 10 includes a horizontal screw 101 and a horizontal nut 102 that cooperates with the horizontal screw 101. The horizontal screw 101 is parallel to the worktable 1, and its two ends are rotatably connected to the fixed base 6 and the connecting platform 104, respectively. The connecting platform 104 is fixed to the worktable 1. The horizontal nut 102 is slidably connected to the worktable 1 via a horizontal sliding component 103. The horizontal nut 102 is rotatably connected to the bottom end of the height screw 91. The bottom end of the guide rod 93 is fixed to the horizontal nut 102. The horizontal sliding component 103 includes a horizontal slider mounted on the horizontal nut 102. The horizontal slider is formed in the... The horizontal slide is made in the horizontal groove on the workbench 1. When it is necessary to adjust the horizontal position of the moving seat 7, rotating the horizontal screw 101 can drive the horizontal nut 102 to move closer to or away from the fixed seat 6, so as to adapt to different sizes of pulse flush nozzles 13, so that the two ends of the pulse flush nozzles 13 can be supported more stably. Preferably, a power rod 105 is also rotatably provided on the connecting table 104. The power rod 105 drives the horizontal screw 101 to rotate through the transmission component. The power rod 105 is set perpendicular to the horizontal screw 101 for easy operation. The transmission component can be two meshing bevel gears, which are respectively set on the power rod 105 and the horizontal screw 101.

[0034] The elastic displacement assembly 5 includes an adjusting seat 51, a support spring 52, and a sliding frame 53. The sliding frame 53 is slidably connected to the adjusting seat 51. The support spring 52 connects the adjusting seat 51 and the sliding frame 53. The three sliding frames 53 are respectively fixedly connected to the first sealing block 32, the air inlet plug 42, and the second sealing block 43. When the sealing block and the air inlet plug 42 are connected to the corresponding port, the force they receive causes the support spring 52 to compress. At this time, the sliding frame 53 also slides in cooperation with the adjusting seat 51.

[0035] The adjusting seat 51 includes a sleeve 511 and a fixed frame 512 fixedly connected to the sleeve 511. The fixed frame 512 is slidably connected to the sliding frame 53. The supporting spring 52 connects the sliding frame 53 and the fixed frame 512. One sleeve 511 is sleeved on the moving rod 31, and the other two sleeves 511 are sleeved on the fixed rod 41. An adjusting block 551 is fixed inside the sleeve 511. The adjusting block 551 is slidably engaged with the adjusting groove 55. The adjusting groove 55 is located on the moving rod 31. Both the fixed rod 41 and the sleeve 511 are provided with locking screws 54 along the height direction of the rod body; the sleeve 511 is threaded with locking screws 54, and the position of locking screws 54 is staggered with the position of adjusting grooves 55. When the sleeve 511 slides up and down along the rod body, the adjusting block 551 also slides in the adjusting groove 55, so that the sealing block and the air inlet plug 42 will not deflect during the sliding height adjustment process. When the sealing block and the air inlet plug 42 are adjusted to the appropriate height position, tighten the locking screws 54 to limit the sleeve 511 to the appropriate position on the rod body.

[0036] The driving component includes a telescopic cylinder 11, the telescopic end of which is connected to the moving rod 31. The moving rod 31 is slidably connected to the worktable 1 via a telescopic sliding member 12. The telescopic sliding member 12 includes a telescopic slider installed at the bottom of the moving rod 31. The telescopic slider slides horizontally in a telescopic groove opened on the worktable 1.

[0037] The implementation principle of this utility model is as follows: For example... Figure 4The pulse flushing nozzle 13 shown is tested for leaks. The suction port 13-1 is aligned with the first sealing block 32, the liquid port 13-2 with the second sealing block 43, and the waste liquid port 13-3 with the air inlet plug 42. The pulse flushing nozzle 13 is first placed in the receiving groove of the fixed base 6. The position of the movable base 7 is adjusted according to the length of the pulse flushing nozzle 13, so that the movable base 7 and the fixed base 6 are positioned close to both ends of the pulse flushing nozzle 13, providing balanced support. The clamping parts 8 in the movable base 7 and the fixed base 6 also clamp and limit the pulse flushing nozzle 13. Then, the height of the elastic displacement components 5 is adjusted according to the positions of the three ports, so that the sealing blocks and air inlet plugs 42 correspond to the three ports. The telescopic cylinder 11 is opened, causing the moving rod 31 to approach the fixed base 6, and the first sealing block 32 seals and presses the suction port 13-1. 1. Push the pulse flush nozzle 13 to move until all three ports are closed and sealed by the first sealing block 32, the second sealing block 43, and the air inlet plug 42 respectively. The air inlet plug 42 can be inserted into the waste liquid port 13-3. Turn on the control switch to allow the air source to enter (not shown in the figure). The gas is then introduced into the waste liquid port 13-3 of the pulse flush nozzle 13 through the air pipe 421 and the air inlet plug 42. After a certain period of time, turn off the control switch and observe the pressure gauge (not shown in the figure). If the pointer of the pressure gauge always points to a fixed pressure value and remains unchanged, it indicates that there is no gas leakage in the pulse flush nozzle 13, and the sealing performance of the pulse flush nozzle 13 is good and the quality inspection is qualified. If the pointer of the pressure gauge initially points to a fixed pressure value, but the pressure value gradually decreases over time, it indicates that there is air leakage in the pulse flush nozzle 13, and the sealing performance of the pulse flush nozzle 13 is poor and the quality inspection is unqualified.
