Description

Technical Field

[0001] The invention relates to the technical field of sterilization devices, in particular to a radiation sterilization device and a sterilization method for medical supplies. Background Art

[0002] Medical supplies are a general term for items used to treat wounds or diseases. Radiation disinfection and sterilization equipment uses ionizing radiation or electromagnetic radiation to kill pathogens in order to eliminate their toxicity. It mainly uses the bactericidal effect of ultraviolet rays to photolyze and denature bacterial proteins, leading to bacterial death, thereby sterilizing medical supplies.

[0003] In the prior art, the medical supplies radiation disinfection and sterilization device and sterilization method disclosed in the Chinese patent with publication number "CN114344493B" cooperate with each other through the push component, the preheating and sterilization component and the driving component. The driving component can make the driving motor, the driving worm, the limit block, the mounting worm gear and the connecting worm gear cooperate with each other, so as to drive the mounting screw and the connecting screw on the mounting worm gear and the connecting worm gear to rotate, so that the pushing component and the preheating and sterilization component can be adjusted and swung. The pushing component can make the mounting screw, the mounting worm gear, the connecting sleeve block and the connecting push rod cooperate with each other, so that the connecting push rod can push the pushing plate, so that the pushing plate can drive the sterilization concave plate on the movable sleeve block to move left and right, thereby accelerating the drying of the medical supplies inside the sterilization concave plate, and solving the problem that the existing sterilization device cannot adjust and sterilize the medical supplies, resulting in some medical supplies still being sterilized unsatisfactorily during the sterilization process, thereby reducing the sterilization effect.

[0004] Existing medical supplies need to be sterilized by a sterilization device when in use to avoid infection when treating wounds. In the scheme described above, hot air is discharged into the box for preheating, and then the sterilization concave plate is moved left and right, and the medical supplies are sterilized by the radiation lamp. However, when the airflow is introduced into the box, the airflow cannot be quickly and evenly distributed in the box due to the positioning of the exhaust hole, which reduces the preheating efficiency inside the box. In addition, since the sterilization concave plate can only move left and right and cannot rotate radially, the medical supplies in contact with the bottom of the sterilization concave plate cannot be irradiated by the radiation lamp.

[0044] A radiation disinfection and sterilization method for medical supplies, based on the above-mentioned radiation disinfection and sterilization device for medical supplies, comprises the following steps:

[0045] S1. When in use, the box door 40 is opened by the handle 41, and then the medical supplies to be sterilized are placed between the two clamping plates 13. By rotating the cross-rotating plate 20, the two clamping plates 13 are positioned to position the medical supplies by using the first bearing 14 and the limit of the slide groove 12.

[0047] S3. The hot air blower 28 is started, and the hot air flow generated by the hot air blower 28 will pass through the exhaust pipe 29 into the hose 30. The hot air flow in the hose 30 will be discharged into the interior of the sterilization box 1 through the exhaust pipe 34 on the shunt pipe 33. At the same time, the multiple sets of driving gear blocks 38 on the driving disk 42 cooperate with the driven gear 36 on the stabilizing shaft 35, and the reset function of the torsion spring 37 is used to ensure that the shunt pipe 33 is in a reciprocating swinging state, and ensure that the air flow discharged from the exhaust pipe 34 can quickly and evenly enter the interior of the sterilization box 1, thereby completing the functions of drying and high-temperature disinfection of medical supplies.

[0048] Working principle:

[0049] When in use, the box door 40 is opened by the handle 41, and then the medical supplies to be sterilized are placed between the two clamping plates 13.

[0050] When the hot air blower 28 is started, the hot air flow generated by the hot air blower 28 will be passed into the hose 30 through the exhaust pipe 29, and the hot air flow in the hose 30 will be discharged into the interior of the sterilization box 1 through the exhaust pipe 34 on the shunt pipe 33. The hot air flow contacts the rotating medical supplies to achieve the drying of the medical supplies and the high temperature effect.

[0051] When the rotating shaft 3 and the positioning rod 4 rotate, the rotating shaft 3 and the driving disk 42 on the fixed shaft 5 rotate synchronously, and the first bevel gear 21 on the driving disk 42 cooperates with the middle bevel gear 27 on the fixed block 26, thereby driving the middle bevel gear 27 to rotate, and then the middle bevel gear 27 cooperates with the second bevel gear 25 on the driving ring 24, so that the sterilization lamp 8 on the driving ring 24 is limited and rotated by the first limit block 22 and the second limit block 23, and the sterilization effect of the medical supplies is improved by the reverse rotation of the sterilization lamp 8 and the medical supplies;

[0052] By utilizing the cooperation of multiple sets of driving gear blocks 38 on the driving disk 42 and the driven gear 36 on the stabilizing shaft 35, and through the reset function of the torsion spring 37, it is ensured that the shunt pipe 33 is in a reciprocating swinging state, and the airflow discharged from the exhaust pipe 34 can quickly and evenly enter the interior of the sterilization box 1, thereby improving the drying and high-temperature disinfection effects of medical supplies.

The radiation disinfection and sterilization device for medical supplies according to claim 1, characterized in that: The side end surface of the sterilization box (1) is fixedly connected to an exhaust pipe (39), and the front surface of the sterilization box (1) is provided with a box door (40), and the box door (40) is provided with a handle (41).

10. A method for radiation disinfection and sterilization of medical supplies, based on a radiation disinfection and sterilization device for medical supplies according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. When in use, the box door (40) is opened by the handle (41), and then the medical supplies to be disinfected are placed between the two clamping plates (13). By rotating the cross-rotating plate (20), the two clamping plates (13) are positioned to position the medical supplies by using the limiting function of the first bearing (14) and the slide groove (12). Then, the positioning rod (4) on the rotating shaft (3) is driven to rotate by the motor (2). By using the cooperation between the first connecting rod (15) and the second bearing (17), and the cooperation between the auxiliary gear (18) and the arc-shaped toothed plate (19) on the second connecting rod (16), it is ensured that the medical supplies rotate radially while rotating axially. S2, when the rotating shaft (3) and the positioning rod (4) are rotating, the rotating shaft (3) and the driving disk (42) on the fixed shaft (5) rotate synchronously, and the first bevel gear (21) on the driving disk (42) cooperates with the middle bevel gear (27) on the fixed block (26), thereby driving the middle bevel gear (27) to rotate, and then the middle bevel gear (27) cooperates with the second bevel gear (25) on the driving ring (24), so that the sterilization lamp (8) on the driving ring (24) rotates within the upper limit of the first limit block (22) and the second limit block (23), and the sterilization effect of the medical supplies is improved by the opposite rotation of the sterilization lamp (8) and the medical supplies; S3. The hot air blower (28) is started, and the hot air flow generated by the hot air blower (28) is passed into the hose (30) through the exhaust pipe (29). The hot air flow in the hose (30) is discharged into the interior of the sterilization box (1) through the exhaust pipe (34) on the shunt pipe (33). At the same time, the multiple groups of driving gear blocks (38) on the driving disk (42) cooperate with the driven gear (36) on the stabilizing shaft (35), and the reset function of the torsion spring (37) is used to ensure that the shunt pipe (33) is in a reciprocating swinging state, and ensure that the air flow discharged from the exhaust pipe (34) can quickly and evenly enter the interior of the sterilization box (1), thereby completing the functions of drying and high-temperature disinfection of medical supplies.
