Description

Technical Field

[0001] This invention relates to the field of pretreatment for cleaning and disinfection of medical instruments, specifically a portable multifunctional medical instrument pretreatment box. Background Technology

[0002] In a Central Sterile Supply Department (CSSD), reusable medical instruments must undergo enzyme soaking pretreatment before entering the cleaning process to break down residual organic matter such as blood and tissue fluid on the surface of the instruments.

[0003] Currently, the commonly used soaking devices in the industry are mostly fixed stainless steel soaking tanks or simple plastic soaking boxes without supports. The main structure is a rectangular tank with a fixed bottom and no movement or height adjustment function. Some equipment is only equipped with a wired heating device in a fixed position.

[0004] Commonly used soaking devices have the following problems: 1. Poor mobility and limited adaptability: Fixed soaking tanks cannot be flexibly transferred between the decontamination area, temporary storage area and cleaning area according to the workflow, which leads to repeated handling of equipment, increases the risk of cross-contamination and the labor intensity of staff.

[0005] 2. The height is not adjustable, which may cause occupational injuries: The fixed height of the soaking tank cannot be adapted to operators of different heights. Long-term bending or lifting operations may cause lumbar spine, shoulder and neck injuries.

[0006] 3. Handling instruments can easily wet sleeves, posing an occupational exposure risk: When the soaking tank is deep, operators need to reach deep into the liquid to handle instruments at the bottom. Their sleeves are easily wetted by the enzyme solution, which not only affects their work but also poses a risk of contact infection.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figures 1-9 The illustration shows a portable multifunctional medical instrument pretreatment box, comprising: an immersion tank 1 and two symmetrically distributed support rods 9 fixed to the bottom of the immersion tank 1. Each support rod 9 has a sleeve 10 slidably fitted at its bottom, and the bottom of the two sleeves 10 is fixedly provided with a base plate 14. The bottom of the base plate 14 is provided with four pulleys 15 arranged in a matrix with a braking function. The inner wall corners of the immersion tank 1 are rounded to avoid the inconvenience of cleaning in narrow corners. The bottom of the immersion tank 1 is connected to a drain pipe 33 via an electrically controlled valve 32. The electrically controlled valve 32 is fixed to the bottom of the immersion tank 1. By opening and closing the electrically controlled valve 32, the enzyme solution in the immersion tank 1 can be automatically discharged to a designated position through the drain pipe 33, thereby facilitating the operator to manually pour out the enzyme solution in the immersion tank 1. The material of the drain pipe 33 is the same as that of the immersion tank 1, and the valve core structure of the electrically controlled valve 32 is also made of corrosion-resistant material. It also includes: a heating unit for continuously heating the enzyme solution in the soaking tank 1 to maintain the temperature, the heating unit being disposed on the outer wall of the soaking tank 1; The support unit is used to support the instruments soaked in the enzyme solution. The support unit is located inside the soaking tank 1. A limiting unit is used to limit the position of the support rod 9 within the sleeve 10. The limiting unit is located between the support rod 9 and the sleeve 10 on the same side.

[0026] The heating unit includes a rechargeable power supply 6 fixed to the bottom of the soaking tank 1. A corrosion-resistant and sealed heating block 7 is fixedly installed on the inner wall of the soaking tank 1. The corrosion-resistant and sealed heating block 7 is electrically connected to the rechargeable power supply 6, which provides heating power to the corrosion-resistant and sealed heating block 7. A temperature control display screen 8 for displaying and adjusting the temperature of the corrosion-resistant and sealed heating block 7 is also fixedly installed on the outer wall of the soaking tank 1. The temperature control display screen 8 is also electrically connected to the rechargeable power supply 6, which provides power to the temperature control display screen 8. The corrosion-resistant and sealed heating block 7 is located below the surface of the enzyme solution. After the enzyme solution is poured into the soaking tank 1, the rechargeable power supply 6 can provide power to the corrosion-resistant and sealed heating block 7, allowing the corrosion-resistant and sealed heating block 7 to heat the enzyme solution in the soaking tank 1.

[0027] The four casters 15 are omnidirectional casters, which facilitate the movement of the soaking tank 1 by staff.

[0028] Two pulleys 15 located on the same side are omnidirectional wheels, and the other two pulleys 15 are directional wheels.

[0029] The supporting unit includes a float 2 that is movably placed inside the soaking tank 1. The float 2 has several through holes 3 inside. The upper end of the float 2 is provided with a lifting member to facilitate the upward movement of the float 2 immersed in the enzyme solution. When the enzyme solution is poured into the soaking tank 1, the enzyme solution will flow through the through holes 3 and the gap between the soaking tank 1 and the float 2 to the bottom of the float 2, and the float 2 will float up. The buoyancy force on float 2 when it is immersed in enzyme solution is F1, the weight of float 2 is F2, and the weight of instrument is F3. F2+F3>F1, which ensures that the instrument can be completely immersed in enzyme solution after being placed on float 2, allowing the enzyme solution to fully enzymatically decompose the stains on the surface of the instrument.

[0030] The lifting component includes an inverted U-shaped rod 4, with both ends of the U-shaped rod 4 fixed to the float plate 2. When the float plate 2 is immersed in the enzyme solution, the upper part of the U-shaped rod 4 is outside the enzyme solution, which makes it convenient for staff to move the float plate 2 and the instrument upward without contacting the enzyme solution.

[0031] The lifting device includes a T-shaped rod 5, which is fixed at the center of the float plate 2. The top of the T-shaped rod 5 is located above the surface of the enzyme solution, making it convenient for workers to remove the float plate 2 from the enzyme solution using the T-shaped rod 5.

[0032] The limiting unit includes a limiting block 11 fixed to the top of the sleeve 10. The inner wall of the limiting block 11 coincides with the inner wall of the sleeve 10. A connecting rod 20 is slidably inserted on the side of the two limiting blocks 11 that are close to each other. A sliding plate 17 is fixedly sleeved on the end face of the two connecting rods 20 that are far from each other, and the sliding plate 17 is slidably assembled inside the limiting block 11. The connecting rod 20 intersects the axis of the sleeve 10 perpendicularly. A limiting post 18 is fixedly provided on the end of the sliding plate 17 that is far from the connecting rod 20. Several equidistant, linearly spaced points are opened on the outer surface of the support rod 9. The positioning hole 21 of the cloth is slidably fitted with the limiting post 18. A spring 19 is fixed between the side of the slide plate 17 away from the support rod 9 and the limiting block 11. A synchronization component is provided between the two connecting rods 20. The spring 19 applies elastic pressure to the slide plate 17, which can keep the limiting post 18 embedded in the positioning hole 21, that is, keep the support rod 9 stable in the sleeve 10. Under the action of the synchronization component, the two limiting posts 18 can be simultaneously withdrawn from the positioning hole 21 or simultaneously embedded in the positioning hole 21.

[0033] The synchronization component includes a connecting frame 12 fixed between two limiting blocks 11. A connecting rod 20 is slidably inserted into the connecting frame 12. Triangular blocks 24 are fixedly provided at the opposing ends of the two connecting rods 20. The triangular blocks 24 are right-angled triangles, and the inclined surfaces of the two triangular blocks 24 are placed away from each other. A vertical pull rod 13 is slidably inserted into the bottom center of the connecting frame 12. A connecting plate 22 is fixedly provided at the top of the pull rod 13 and is located inside the connecting frame 12. Two sliding plates 23 are distributed above the inclined surface of each triangular block 24. The sliding plates 23 are fixed to the bottom of the connecting plate 22, and the bottom of the sliding plates 23 is dome-shaped. When the pull rod 13 moves downward with the connecting plate 22, it can push the inclined surface of the triangular block 24 through the dome bottom of the sliding plate 23, thereby making the two triangular blocks 24 move towards each other. A trigger is also provided at the bottom of the pull rod 13. Under the action of the trigger, the position of the two triangular blocks 24 can be adjusted by foot pedal.

[0034] The actuating element includes a collar 25 fixedly sleeved on the outer surface of the pull rod 13, and the collar 25 is located below the connecting frame 12. A tension spring 26 is fixedly installed between the upper end face of the collar 25 and the connecting frame 12, and the tension spring 26 is sleeved on the outside of the pull rod 13. The bottom of the pull rod 13 slides through the base plate 14. A rocker plate 28 is hinged to the bottom of the base plate 14. A slot 29 is opened inside the rocker plate 28. The pull rod 13 passes through the slot 29. The bottom of the pull rod 13 is fixed. A vertical crossbar 27 is fixedly provided, and the lower end of the rocker 28 slides on the crossbar 27. A rubber pad 30 is fixedly provided on the upper surface of the end of the rocker 28 away from the hinge point, and several friction elements 31 for increasing friction are also fixedly provided on the upper surface of the rubber pad 30. The friction elements 31 are protrusions or grooves. By pressing down on the front end of the rocker 28, the pull rod 13 can be moved downward, thereby causing the slide plate 23 to push the triangular block 24.

[0035] Example 2: Please refer to Figure 5 This embodiment is a further explanation of the above embodiment. The upper port of the soaking tank 1 is provided with a stepped part 16. After the float 2 is lifted by the lifting member and rotated at a certain angle, the float 2 can be placed on the stepped surface of the stepped part 16, thereby facilitating the drainage of enzyme solution from the float 2 and the surface of the instrument.

[0036] Working principle: In this solution, the soaking tank 1 is made of food-grade ductile plastic, which makes the tank lightweight and also wear-resistant and corrosion-resistant. The support rod 9, sleeve 10 and base plate 14 are made of stainless steel. When the height of the soaking tank 1 needs to be adjusted, the operator only needs to keep the soaking tank 1 in a stationary state and press the rocker arm 28 with their foot. The base plate 14 limits the pull rod 13, allowing the rocker arm 28 to slide down the pull rod 13 via the crossbar 27. In addition, the rubber pad 30 and friction element 31 can also increase the friction between the operator's shoe sole and the rocker arm 28, preventing slippage. As the lever 13 moves downwards with the connecting plate 22, the bottom of the slide plate 23 applies pressure to the inclined surface of the triangular block 24, allowing the two triangular blocks 24 to move closer to each other. That is, the connecting rod 20 allows the limiting post 18 to retract into the interior of the limiting block 11, no longer engaging with the positioning hole 21. At this time, the operator can lift the soaking tank 1 upwards or press it downwards to adjust the height of the soaking tank 1. After adjustment, the operator releases the foot pedal 28 and then makes a fine adjustment to the height of the soaking tank 1 so that the limiting post 18 can engage with the nearest positioning hole 21 again, thus completing the adaptive adjustment of the height of the soaking tank 1.

[0037] When the enzyme solution is poured into the soaking tank 1, the float plate 2 will float inside the soaking tank 1. At this time, the instruments that need to be soaked in the enzyme solution are placed on the float plate 2 in sequence. After the instruments are placed, the weight of the instruments will press the float plate 2 down, so that the enzyme solution can completely soak the instruments. At the same time, the power supplied by the rechargeable power supply 6 to the corrosion-resistant sealing heating block 7 can heat the enzyme solution in the soaking tank 1 and maintain the enzyme solution temperature between 25-45℃ with an accuracy of ±1℃ to meet the activity requirements of different enzyme solutions. After soaking, when the instruments need to be retrieved, the staff can directly lift the float plate 2 upwards using the U-shaped bar 4 or T-shaped bar 5 located above the liquid surface. After lifting, the float plate 2 can be rotated slightly so that it can rest on the step section 16. Then, wait for the enzyme solution on the float plate 2 and the instruments to drip down automatically before transferring the instruments. This avoids the sleeves being soaked in enzyme solution when the instruments are taken out, effectively reducing the risk of occupational exposure.
