Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hemodialysis, in particular to a device for rotating and knocking perfusion device. BACKGROUND

[0002] Combined hemodialysis and hemoperfusion treatment can increase the clearance of uremic toxins, especially large molecular weight toxins, protein-bound toxins and various inflammatory mediators, significantly improve the quality of life of patients, and is one of the important means to improve the long-term survival rate of uremic patients. Clinically, the patient's condition is regularly treated with hemoperfusion and hemodialysis for 2 hours. Before treatment, the perfusion device needs to be pre-flushed and degassed. The most commonly used degassing method is irregular hammering. The nurse holds the perfusion device with one hand and knocks the perfusion device intermittently with the other hand to speed up the air exhaust of the perfusion device. Clinically, it is found that the nurse cannot leave to do other work, especially when multiple perfusion devices need to be knocked at the same time, which is time-consuming, inefficient, occupies the nurse's time, increases the nurse's labor cost, and reduces the work efficiency. At the same time, due to irregular knocking, the perfusion device is not fully degassed, which increases the risk of blood clotting and reduces the treatment effect.

[0003] Some schemes for knocking the perfusion device to exhaust air are disclosed in the prior art documents, for example, CN220917866U, an automatic perfusion device degassing device, CN220879806U, an automatic blood perfusion device flushing device, CN221579140U, a blood perfusion device, etc., but the knocking efficiency is low.

In the absence of explicit evidence that the above content has been disclosed on the filing date of the present patent application, the above background art should not be used to evaluate the novelty and inventiveness of the present application.

[0023] The utility model will be further explained in detail in combination with specific implementation manners and by referring to the drawings. It should be emphasized that the following explanation is only exemplary and is not intended to limit the scope of the utility model and its applications.

[0024] Non-limiting and non-exclusive embodiments will be described with reference to the following drawings, in which the same reference numerals indicate the same parts unless otherwise specifically indicated.

[0025] As Figures 1-4 shown in a kind of rotating knocking perfusion device, including workbench 2, mounting seat 3, motor 1, disc 6 and knocking mechanism, the motor 1 is fixed on the workbench 2, the disc 6 is installed at the end of the drive shaft 11 of the motor 1, and is linked with the drive shaft 11. At least 1 the mounting seat 3 is fixed on the workbench 2 by bolt 33, and at the side of the disc 6, for fixing perfusion device 4;3-5 the one end of the knocking mechanism is distributed around the disc 6, and the other end extends towards the mounting seat 3, so that when disc 6 rotates, the knocking mechanism can intermittently knock the perfusion device 4 fixed on the mounting seat 3. Preferably, 3-6 mounting seats 3 are circumferentially distributed at the side of the disc 6, to improve the efficiency of knocking perfusion device 4, to meet the demand of concentrated use of perfusion device 4. After the perfusion device 4 is fixed on the mounting seat 3 in the device, the motor 1 is started, i.e. the knocking mechanism can be used to reciprocatingly knock the perfusion device 4, and 3-6 perfusion devices 4 can be knocked at a time, with high working efficiency, reduces the labor intensity of nurses, and nurses do not need to monitor at all times, liberates labor.

[0026] In preferred embodiments, Figure 3 Also include horseback card 5, utilize horseback card 5 to fix the perfusion device 4 on the mounting seat 3, and it is convenient to disassemble and assemble. 2 horseback cards 5 are fixed on the upper portion and the lower portion of the perfusion device 4 respectively, and the middle portion of the knocking mechanism is knocked on the perfusion device 4.

[0027] In some embodiments, the upper part of the mounting seat 3 is a square column, and the lower part is fixed on the workbench 2 by bolts 33. The square column is provided with an arc-shaped groove 35 from top to bottom. Preferably, the radius of the arc-shaped groove 35 is matched with the size of the perfusion device 4, so as to enhance the fixing effect of the horse clamp 5 on the perfusion device 4. The bolt for locking the horse clamp 5 is threaded out from the other side of the mounting seat 3, and then a wing nut 51 is screwed to lock it, so as to prevent the bolt from slipping due to frequent loosening. When the perfusion device 4 is fixed, the lower part of the perfusion device 4 is abutted against the bottom of the arc-shaped groove 35, the horse clamp 5 is pressed against the perfusion device 4, and then the bolt is tightened to press the perfusion device 4 against the inner side of the arc-shaped groove 35. By fixing the perfusion device 4 by the horse clamp 5, the perfusion device 4 is basically not moved during the process of knocking, so as to ensure that the connection between the drip tube 9 and the perfusion device 4 is not loosened. Preferably, the mounting seat 3 is further provided with a baffle 32 on the lower side of the arc-shaped groove 35, which is used to prevent the knocking mechanism from mistakenly hitting the drip tube 9.

[0028] The knocking mechanism has a certain elasticity or stress deformation, so as to change the working radius of the knocking mechanism. For example, one of the embodiments of the knocking mechanism is a rubber rod or a PU rod, etc. The rear end of the rubber rod is fixed on the outer side of the disc 6. When the disc 6 rotates by a certain angle, the front end of the rubber rod hits the middle part of the perfusion device 4. The disc 6 continues to rotate, the rubber rod is elastically deformed under stress, and then passes along the front side of the perfusion device 4. The noise generated by the rubber rod knocking the perfusion device 4 is small.

[0029] In combination Figure 4 , another embodiment of the knocking mechanism includes a positioning seat 8, a knocking rod 7 and a torsional spring 82. The positioning seat 8 is fixed on the outer side of the disc 6. The knocking rod 7 is rotatably connected to the positioning seat 8 through a pin shaft 81. The torsional spring 82 is installed on the pin shaft 81, one end of which is connected to the rear end of the knocking rod 7, and the other end is abutted against the bottom of the positioning seat 8, so that the knocking rod 7 is close to perpendicular to the disc 6 under the action of the torsional spring 82 in the normal state. When the motor 1 rotates by a certain angle, the knocking rod 7 hits the side surface of the perfusion device 4. The motor 1 continues to rotate, and the knocking rod 7 has a reverse rotation tendency. The torsional spring 82 is deformed under stress, so that the working radius of the knocking rod 7 is reduced, and then the knocking rod 7 passes along the front side of the perfusion device 4. Preferably, the knocking rod 7 is a rubber rod or a PU rod, etc.
