Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-3The first embodiment provides a dialysis hollow fiber filter exhaust device, comprising: a vibration assembly 1, the vibration assembly 1 comprises a vibration motor 11, and the vibration motor 11 is electrically connected to a power switch; a clamping assembly 2, the clamping assembly 2 comprises a first clamping arm 21 and a second clamping arm 22, the tail end of the first clamping arm 21 is connected to a first sleeve ring 23, the first sleeve ring 23 is sleeved on the vibration motor 11, the tail end of the second clamping arm 22 is connected to a second sleeve ring 24, the second sleeve ring 24 is sleeved on the vibration motor 11, the first clamping arm 21 and the second clamping arm 22 are located on the same horizontal plane, and a control handle 25 is installed on the side of the first sleeve ring 23 opposite to the first clamping arm 21; a handle 3, the handle 3 is installed on the side of the second sleeve ring 24 opposite to the second clamping arm 22.
[0029] Specifically, the vibration motor 11 in the vibration assembly 1 is used to vibrate the clamping assembly 2, so as to vibrate the filter column clamped by the clamping assembly 2 to complete the removal of gas in the filter column. The power switch completes the control of the vibration motor 11. The first clamp arm 21 and the second clamp arm 22 form a clamping arm. The second ring 24 connected to the tail end of the second clamp arm 22 and the second ring 24 connected to the tail end of the second clamp arm 22 are sleeved on the vibration motor 11. The two rings rotate with the vibration motor 11 as the center, driving the first clamp arm 21 and the second clamp arm 22 to open and close, completing the clamping of the filter column. The first ring 23 is The control handle 25 installed on the side opposite to the first clamping arm 21 controls the rotation of the second ring 24, and the handle 3 acts on the medical staff to hold the device during use; when in use, the medical staff holds the handle 3, places the filter column between the two clamping arms, rotates the control handle 25 to complete the clamping of the filter column, and then turns on the power switch, the vibration motor 11 works, and vibrates the filter column clamped by the clamping assembly 2 to complete the removal of gas in the filter column. The device is easy to operate and reduces the workload of medical staff. At the same time, the gas in the filter column is removed more thoroughly, reducing the risk of air embolism.
[0030] In some possible embodiments, a spring groove 26 is provided on the contact surfaces of the first ring 23 and the second ring 24; a clamping force rebound assembly 27 is installed on the clamping assembly 2, and the clamping force rebound assembly 27 includes a telescopic spring 271 arranged in the spring groove 26, one end of the telescopic spring 271 is installed on the first ring 23, and the other end of the telescopic spring 271 is installed on the second ring 24.
[0031] Specifically, the clamping force rebound assembly 27 simplifies the operation of the device. A spring groove 26 is provided on the contact surface of the first ring 23 and the second ring 24. A telescopic spring 271 connected to the first ring 23 and the second ring 24 at both ends of the spring groove 26 provides torque between the first ring 23 and the second ring 24. When the second ring 24 or the first ring 23 rotates, the tension provided by the telescopic spring 271 can return the position between the first ring 23 and the second ring 24 to the correct position, thereby providing continuous clamping force between the first clamp arm 21 and the second clamp arm 22.
[0032] In some possible implementations, two spring slots 26 are provided on the contact surfaces of the first ring 23 and the second ring 24 . The two spring slots 26 are located on both sides of the vibration motor 11 , respectively. A telescopic spring 271 is correspondingly disposed in each spring slot 26 .
[0033] Specifically, if Figure 3 As shown, the two sets of clamping force rebound components 27, i.e., two telescopic springs 271, further increase the torque between the first ring 23 and the second ring 24, and further increase the clamping force between the first clamping arm 21 and the second clamping arm 22. The two sets of clamping force rebound components 27 are located on both sides of the vibration motor 11 so that the force generated is more balanced.
[0034] In some possible implementations, the power switch is mounted on the control handle 25 .
[0035] Specifically, the power switch is mounted on the control handle 25 to facilitate the operation of the device.
[0036] In some possible implementations, the cross-sections of the first clamping arm 21 and the second clamping arm 22 are both arc-shaped, and the first clamping arm 21 and the second clamping arm 22 are combined to form a semi-enclosed structure to form a clamping area.
[0037] Specifically, the filter column is cylindrical, and the cross-sections of the first clamping arm 21 and the second clamping arm 22 are both arc-shaped. The semi-enclosed structure is more suitable for clamping the filter column. When the first clamping arm 21 and the second clamping arm 22 clamp the filter column, the matching shape can improve the clamping stability and avoid deformation of the filter column caused by clamping.
[0038] In some possible implementations, a latex layer 28 is respectively installed on the clamping surfaces of the first clamping arm 21 and the second clamping arm 22 .
[0039] Specifically, the latex layer 28 is made of a relatively soft material and has a certain degree of resilience. Arranging the latex layer 28 on the clamping surface of the first clamping arm 21 and the second clamping arm 22 can better protect the filter column and further avoid deformation of the filter column caused by clamping. At the same time, the friction of the latex layer 28 is greater. When the first clamping arm 21 and the second clamping arm 22 clamp the filter column and the vibration motor 11 is working, the filter column will not fall off due to the friction of the latex layer 28.
[0040] In some possible implementations, the handle 3 is mounted on a side of the second ring 24 opposite to the second clamp arm 22 via a shock absorbing assembly 4 .
[0041] Specifically, when the vibration motor 11 is working and the clamping assembly 2 is vibrated, the handle 3 connected to the second ring 24 will also be affected. The medical staff's hand holding the handle 3 will be vibrated, which will cause arm numbness over time. The shock absorbing assembly 4 between the second ring 24 and the second handle 3 reduces the influence of the vibration motor 11 on the handle 3, and provides a certain protection for the medical staff's hand. The handle 3 is installed on the second ring 24 on the side opposite to the second clamp arm 22 through the shock absorbing assembly 4, so that the handle 3, the second clamp arm 22 and the second ring 24 are in a straight line, which is convenient for users to use.
[0042] In some possible implementations, the shock absorbing assembly 4 includes a shock absorbing spring 41 and a shock absorbing telescopic rod 42, the shock absorbing spring 41 is sleeved on the shock absorbing telescopic rod 42, one end of the shock absorbing spring 41 is mounted on the second ring 24 on the side opposite to the second clamp arm 22, and the other end of the shock absorbing spring 41 is mounted on the handle 3.
[0043] Specifically, the shock-absorbing spring 41 is sleeved on the shock-absorbing telescopic rod 42, and the two shock-absorbing devices work together to increase the shock-absorbing efficiency of the shock-absorbing assembly 4. The shock-absorbing telescopic rod 42 has a certain hardness to prevent the handle 3 from bending due to vibration when in use. The shock-absorbing spring 41 has a better shock-absorbing effect. The combination of the two takes into account both shock-absorbing and anti-deformation effects.
[0044] In some possible implementations, the cross section of the handle 3 is circular.
[0045] Specifically, the circular handle 3 has more gripping positions, which is convenient for users to hold at different angles. Medical staff can use it at an angle that is comfortable for them, further reducing the intensity of use by medical staff. Finally, it should be noted that the above embodiments are only specific implementation methods of the utility model, which are used to illustrate the technical solution of the utility model, rather than to limit it. The protection scope of the utility model is not limited to this. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the above embodiments within the technical scope disclosed by the utility model, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiment of the utility model. They should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
[0046] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
