A cuff disinfection device for electrocardiogram monitoring and a method of using the same

Abstract

This invention relates to the field of medical disinfection technology, specifically to a cuff disinfection device and method for use in electrocardiogram (ECG) monitoring, comprising a base with a fixing clamp fixedly mounted on the bottom of the base. This ECG cuff disinfection device and method involves driving a roller to rotate counterclockwise, pushing the cuff into the insertion area and limiting it between a limiting strip and a cover plate. After disinfection, the roller rotates clockwise, pushing the cuff out of the insertion area in the opposite direction. Compared to existing cuff disinfection methods using a pull-out structure, the roller and insertion area work together to achieve quick cuff insertion and removal via the forward and reverse rotation of the roller. The user simply inserts the cuff into the insertion port without much assistance, offering excellent ease of use. Furthermore, the circular motion of the insertion area automatically discharges the irradiated cuff, and the discharge, insertion, and irradiation processes do not interfere with each other, thus achieving a streamlined cuff disinfection process and improving disinfection efficiency.

Description

Technical Field

[0001] The invention relates to the technical field of medical disinfection, and in particular to a cuff disinfection device for electrocardiogram monitoring and a use method thereof. Background Art

[0002] ECG monitoring equipment needs to use a cuff to contact the patient. The cuff directly contacts the human skin during use. Therefore, regardless of whether the cuff is contaminated, it needs to be disinfected for each patient. Common methods of cuff disinfection include soaking in chlorine-containing disinfectants, wiping with 75% alcohol, and ultraviolet light irradiation. Taking ultraviolet irradiation disinfection as an example:

[0003] The existing patent (publication number: CN117281931A) discloses a cuff disinfection device for ECG monitoring, which belongs to the field of medical disinfection technology. The cuff disinfection device includes a winding disinfection cylinder, which includes a rotating light cylinder and a pull-out light belt connected to and wrapped around the outer wall of the rotating light cylinder. A clamping space for the winding cuff is formed between the pull-out light belt and the rotating light cylinder. The pull-out light belt and the rotating light cylinder are ultraviolet light sterilization parts, which are used to disinfect the front and back sides of the cuff arranged in the clamping space. The pull-out light belt includes a heating wire, which is used to heat the cuff. The above-mentioned pull-out structure is difficult to quickly and automatically fix the cuff, and the two steps of pulling and retracting cannot be performed at the same time, which affects the disinfection efficiency.

[0006] A cuff loader is arranged on the lamp tube and the base.

[0007] The cuff loader includes a rotating ring rotatably connected to the outside of the lamp tube, and a motor is fixedly installed inside the lamp tube. A through opening is opened on the surface of the lamp tube, and a driving gear is fixedly installed on the rotating shaft of the motor, and the driving gear passes through the through opening and is transmission-connected to the rotating ring.

[0008] Four partitions are fixedly installed on the top of the rotating ring, and the four partitions divide the upper side of the rotating ring into four insertion areas for placing cuffs respectively. A plurality of limit bars are fixedly set on the side of the insertion area close to the lamp tube, and a cover plate is fixedly set on the side of the insertion area away from the lamp tube. An insertion opening is set between the partition and the counterclockwise cover plate, and a roller is rotatably set on the partition, and the shaft of the roller passes through the rotating ring and is fixedly connected to a transmission gear.

[0009] The top surface of the base is provided with an annular groove corresponding to the transmission gear, and the transmission gear is located in the annular groove, the inner ring inner wall of the annular groove is provided with a winding tooth ring matching the transmission gear, and the outer ring inner wall of the annular groove is provided with a releasing tooth ring matching the transmission gear.

[0011] Preferably, the scraping assembly comprises a forward-pushing toothed ring provided on the inner wall of the outer ring of the annular groove, and a pull-back toothed ring is provided on the inner wall of the inner ring of the annular groove.

[0012] A rubber strip is fixedly arranged on one side of the surface of the limiting strip opposite to the cover plate.

[0014] Preferably, the alcohol cleaning assembly includes a bracket fixedly mounted on the lamp tube, and a slide is slidably connected to the bracket, the slide is arranged in an L-shaped structure, an alcohol roller is rotatably connected to the vertical frame of the slide, and a spring is arranged on the transverse frame of the slide, and the spring pushes the arc frame and the alcohol roller to move toward the lamp tube.

[0015] A roller inlet is arranged between the partition bar and the clockwise cover plate.

[0016] Preferably, the fixing clamp is fixed to the base by screws.

[0017] Preferably, a dust suction pipe is provided inside the lamp tube near the irradiation port.

[0018] Preferably, an inclined platform is fixedly provided on the side surface of the partition bar close to the insertion opening.

[0019] Preferably, two limiting rings cooperating with the bracket are fixedly provided on the slide.

[0020] A method for using a cuff disinfection device for electrocardiogram monitoring comprises the following steps:

[0021] S1, turn on the UV lamp and start the motor;

[0022] S2. The motor drives the rotating ring to rotate at a low speed by using the driving gear, so that the transmission gear on the rotating ring makes a circular motion along the ring groove. After the transmission gear contacts the winding gear ring, it is driven to drive the roller to rotate counterclockwise. At this time, the side of the cuff is placed on the insertion port, and the cuff can be pushed into the insertion area by the roller and limited between the limit strip and the cover plate. When the insertion area that follows the circular motion of the rotating ring reaches the irradiation area, the light of the ultraviolet lamp passes through the irradiation port to irradiate and sterilize the cuff in the insertion area. After the sterilization is completed, the cuff continues to move in a circular motion with the rotating ring. After rotating out of the irradiation area, the transmission gear contacts the release gear ring, and is driven to drive the roller to rotate clockwise. The cuff in the insertion area can be pushed out in the opposite direction, and then the cuff is loaded again for irradiation.

[0023] S3. During the movement of the insertion area in the irradiation area, the transmission gear at the bottom thereof contacts the forward push gear ring and the pull back gear ring alternately, driving the roller to perform quantitative reciprocating rotation and driving the cuff in the insertion area to perform reciprocating displacement;

[0024] S4. When the cuff is discharged during the circular motion of the insertion area, the entrance roller is aligned with the alcohol roller, and the spring pulls the alcohol roller along the entrance roller into the insertion area. As the insertion area moves in a circular motion, the alcohol roller moves between the limit strip and the cover plate for disinfection, and finally detaches from the insertion entrance and contacts the roller for disinfection.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, the roller is driven to rotate counterclockwise, and the side of the cuff is placed at the insertion port. The cuff can be pushed into the insertion area by the roller and limited between the limit strip and the cover plate. After disinfection, the roller is driven to rotate clockwise, and the cuff in the insertion area can be pushed out in the opposite direction. Compared with the existing cuff disinfection using a pull-out structure, the above-mentioned roller cooperates with the insertion area. On the one hand, the forward and reverse rotation of the roller can be used to realize the rapid disassembly and assembly of the cuff. The user only needs to pass the cuff into the insertion port without too much assistance, and the convenience of use is good. On the other hand, the circular motion process of the insertion area can automatically discharge the irradiated cuff, and the discharge, loading and irradiation operations do not interfere with each other, thereby realizing assembly line cuff disinfection and improving disinfection efficiency.

[0027] In the present invention, the transmission gear is alternately in contact with the forward push gear ring and the pullback gear ring to drive the roller to perform a quantitative reciprocating rotation, and drive the cuff in the insertion area to move back and forth, so that the moving cuff is in contact with the rubber strip, so that the rubber strip scrapes the surface of the cuff on the side that contacts the patient, and physically removes debris and dust adhered to the surface, which can effectively improve the disinfection and sterilization effect of the cuff.

[0028] In the present invention, the alcohol roller is pulled by a spring along the roller entrance into the insertion area. With the circular motion of the insertion area, the alcohol roller moves between the limit strip and the cover plate for disinfection, and finally detaches from the insertion entrance and contacts with the roller for disinfection. Compared with the existing alcohol roller fixedly arranged inside the device, the sliding alcohol roller can automatically enter the insertion area after the cuff is released to disinfect it and the roller, and automatically detach from the insertion area before the cuff is installed, which ensures that the position contacting the cuff is disinfected without contacting the cuff to cause impact.
