Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a sterile blister suction device for treating fracture blisters. Background Art

[0002] After a fracture, the permeability of local soft tissue is severely damaged, the vascular endothelium is damaged, followed by embolism, lymphatic reflux obstruction, increased permeability of tissue capillaries, increased fluid exudation, and endogenous water produced by liquefaction necrosis accumulates in the weak points between the epidermis and dermis to form tension blisters. The tension blisters that occur in the acute phase of fracture not only increase the chance of infection and bring pain to patients, but also cause serious complications, complicating the treatment of the disease. After the blisters are formed, they contain a large amount of tissue fluid, which needs to be sucked out in time, otherwise it is easy to cause infection.

[0003] However, the existing method of sucking out blisters is that medical staff hold a syringe, insert the needle on the syringe into the patient's blister, and then operate the piston rod to move inside the syringe to suck the blister from the needle into the syringe. This syringe blister suction method requires the staff to control the insertion position of the needle in the blister. When the needle penetrates the surface layer of the blister and is inserted too deep, it is very easy to cause the needle to pierce the patient's skin in the inner layer of the blister, causing bleeding in the patient, which not only interferes with the blister suction work, but also increases the patient's pain. In addition, the bleeding of the patient's skin mixes with the tissue fluid in the blister, which will also affect the patient's recovery after blister suction. Summary of the invention

The installation of the bracket 28 serves to connect the transverse threaded rod 5 and the connecting rod 29, and the outer wall of the middle part of the bracket 28 is movably connected to the inner wall of the outer end of the transverse threaded rod 5.

[0032] See also Figure 4 and Figure 5 The lifting assembly 10 includes a ball nut 101 and a ball screw 102. The inner wall of the ball nut 101 is threadedly sleeved with the outer wall of the ball screw 102. The threaded sleeve connection method enables the circular rotation of the ball screw 102 to provide power for the vertical lifting movement of the ball screw 102.

The outer wall of the lower end of the ball screw 102 is movably connected with the inner wall of the upper end face of the cylinder 1, and the outer wall of the upper end of the ball screw 102 is movably connected with the inner wall of the upper end of the column 33.

[0034] In summary, when the aseptic blister suction device for treating fracture blisters is used, first, due to the connection mode of the transverse threaded rod 5 and the No. 1 sleeve rod 4 threaded sleeve connection, and the connection mode of the suction cup 8 and the vertical threaded rod 7 threaded sleeve connection, the transverse threaded rod 5 and the vertical threaded rod 7 drive the change of their lengths while rotating in a circle. At the same time, the movable connection between the No. 1 sleeve rod 4 and the cylinder 1, and the movable connection between the transverse threaded rod 5 and the No. 2 sleeve rod 6 are convenient for fixing the suction cup 8 on the patient's skin. Then, the needle tube 2 is clamped on the inner wall of the elastic splint 9, and the ball screw 102 is rotated. Due to the connection mode of the ball screw 102 and the ball nut 101 threaded sleeve connection, the ball screw 102 rotates in a circle and drives the ball nut 101 to move up and down in the vertical direction. When the ball nut 101 moves, the height of the needle tube 2 is adjusted through the connection between the cross bar 30 and the elastic splint 9. At the same time, by observing the movement of the pointer 31 on the scale line 34, the medical staff can intuitively understand the use height of the needle 15. After the needle 15 is inserted into the blister, the medical staff pulls the piston rod 17 inside the needle tube 2 through the piston handle 18. The pulling of the piston rod 17 sucks the tissue fluid in the blister into the inside of the needle tube 2 through the needle 15, and then turns on the power of the electric push rod 12. After the electric push rod 12 is turned on, the extension of its internal output shaft drives the push plate 13 to push the blister. At this time, the movement of the push plate 13 can facilitate the suction of the tissue fluid in the blister into the inside of the needle tube 2. Finally, the valve body 24 is opened. At this time, the medicine in the medicine storage tank 3 is passed from the inside of the medicine outlet pipe 23 to the inside of the connecting pipe 25, and then from the inside of the medicine inlet end 16 through the inside of the medicine inlet end 16 to the inside of the blister, thereby facilitating the dosing operation of the blister after the blister is sucked.
