Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically a blood perfusion device fixing device. Background Technology

[0002] Hemoperfusion removes endogenous and exogenous toxic substances from the human body through adsorption, but it cannot remove excess water from the patient's body. For patients who need to remove medium and large molecules and water, hemodialysis and hemoperfusion, two complementary methods, are often combined and performed simultaneously in clinical practice. However, current dialysis equipment cannot be equipped with a fixation device for the perfusion device, and the fixation device provided by the perfusion device manufacturer may not be suitable for the dialysis machine's built-in support.

[0003] According to CN215585004U, a fixing device for a hemoperfusion device is disclosed. This technology discloses "a fixing device for a hemoperfusion device, including a fixing ring, a telescopic connecting tube, a positioning support ring, and an elastic clamping mechanism. The fixing ring is fixedly connected to the positioning support ring through the telescopic connecting tube. The positioning support ring has a through-hole at its bottom and a through-port on its side. Several adsorption trays are fixed at the bottom of the positioning support ring, and an arc-shaped protective plate is fixed on the side of the positioning support ring. The elastic clamping mechanism is fixed on the arc-shaped protective plate." This technology has the technical effects of "reliable fixing, adjustable clamping force on the hemoperfusion device, and avoiding damage to the hemoperfusion device caused by excessive clamping force."

[0004] The above solution uses a positioning ring to fix the hemoperfusion device and adopts a lifting method to greatly reduce the clamping force on the perfusion device. At the same time, an elastic clamping mechanism is used to position the perfusion device. However, if the hemoperfusion device is not in the center position, the elastic clamping mechanism may not be able to distribute the pressure evenly, causing the perfusion device to shake or shift under uneven force. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a blood perfusion device fixing device. By placing the blood perfusion device between two upper and lower positioning shells, and having the tubes at both ends of the blood perfusion device enter the tube hole through the tube opening, the pressure of the spring rebound, combined with the retaining ring, pushes the extension part to cause the positioning shell to squeeze the blood perfusion device, thereby fixing the blood perfusion device between the upper and lower positioning shells. Because the fixing force on the blood perfusion device is even, the problem of shaking or displacement during use is avoided.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hemoperfusion device fixing device, comprising a fixing mechanism for fixing the hemoperfusion device to a dialysis machine, the fixing mechanism comprising:

[0007] The main components include symmetrically mounted positioning shells that are slidably installed on the upper and lower sides of the front end of the frame. Both ends of the positioning shells have extensions fixed to their outer walls. A guide rod is slidably installed between the extensions of the upper and lower positioning shells. Both ends of the guide rod have retaining rings fixed to them. A spring is installed inside the extension and sleeved on the guide rod.

[0008] A timer component, set on the main component and used for timed reminders;

[0009] The mounting components are set on the timing components and used to fix the entire mechanism to the bracket on the side of the dialysis machine.

[0010] Preferably, the timing component includes a housing fixed in the middle of the rear end of the frame, with a mounting slot inside the housing for installing a timer, flashing lights installed on both sides of the upper end of the housing, and a buzzer installed at one end inside the housing.

[0011] Preferably, the timing component further includes a positioning plate installed on the outer end of the housing. The positioning plate has a second mounting hole at each of its four corners, and the positioning plate is fixed to the housing with bolts through the second mounting holes. The positioning plate is made of soft rubber.

[0012] Preferably, the mounting assembly includes a mounting bracket fixed to the rear end of the housing, with a knob screw threaded through the outer end of the mounting bracket.

[0013] Preferably, the main component further includes baffles installed at both ends of the upper end of the frame. The baffles have first mounting holes on both sides inside, and the baffles are fixed to the frame by bolts through the first mounting holes.

[0014] Preferably, the main component further includes a through-hole at the front end of the positioning shell, and a through-hole is formed inside the positioning shell and communicates with the through-hole.

[0015] Beneficial effects

[0016] This invention provides a blood perfusion device fixing device. Compared with the prior art, it has the following advantages:

[0017] Beneficial effects:

[0018] 1. By placing the hemoperfusion device between the upper and lower positioning shells, and having the tubes at both ends of the hemoperfusion device enter the tube hole through the tube opening, the pressure of the spring rebound, combined with the retaining ring, pushes the extension part to drive the positioning shell to squeeze the hemoperfusion device, thereby fixing the hemoperfusion device between the upper and lower positioning shells. Because the fixing force on the hemoperfusion device is even, the problem of shaking or displacement during use is avoided.

[0019] 2. The countdown timer can be set before use, and reminders will be given one minute before the countdown ends and at the end of the countdown. The reminders include a buzzer sound reminder and a flashing light reminder. The positioning plate is made of soft rubber, so after the timer is installed in the mounting slot of the housing, it can be limited by the positioning plate to prevent it from falling out. In addition, the timer can be directly squeezed out or installed by squeezing the positioning plate. Attached Figure Description

Both ends of the positioning shell 112 have extensions 113 fixed to their outer walls. A guide rod 114 is slidably installed between the extensions 113 of the upper and lower positioning shells 112. Both ends of the guide rod 114 have retaining rings 115 fixed to them. A spring 116 is installed inside the extension 113 and sleeved on the guide rod 114.

[0029] The timing component 12 is set on the main component 11 and used for timed reminders;

[0030] The mounting component 13 is mounted on the timing component 12 and is used to fix the entire mechanism 1 to the bracket on the side of the dialysis machine.

[0031] In this embodiment, the blood perfusion device is placed between the upper and lower positioning shells 112, and the tubes at both ends of the blood perfusion device enter the tube hole 1110 through the tube port 119. Then, the pressure of the spring 116 returning, combined with the retaining ring 115, pushes the extension 113 to drive the positioning shell 112 to squeeze the blood perfusion device, thereby fixing the blood perfusion device between the upper and lower positioning shells 112. Because the fixing force on the blood perfusion device is even, the problem of shaking or displacement during use is avoided.

[0032] Specifically, the timing component 12 includes a housing 121 fixed in the middle of the rear end of the frame 111. The housing 121 has an installation slot 122 inside, and a timer 123 is installed inside the installation slot 122.

The positioning plate 126 is made of soft rubber.

[0035] In this embodiment, the positioning plate 126 is made of soft rubber, so that after the timer 123 is installed inside the mounting slot 122 of the housing 121, it can be limited by the positioning plate 126 to prevent it from falling out.

Then, the pressure of the spring 116 returning, combined with the retaining ring 115, pushes the extension 113 to drive the positioning shell 112 to squeeze the hemoperfusion device, thereby fixing the hemoperfusion device between the upper and lower positioning shells 112.

[0042] Then, the fixing mechanism 1 is installed on the bracket on the side of the dialysis machine, and the bracket is located in the mounting bracket 131. The knob screw 132 is then rotated and tightened to fix it. Finally, the countdown timer 123 is set before use, and reminders are given 5 minutes before the countdown ends and at the end.
