Abstract
Description
Technical Field
[0001] This invention relates to the field of medical testing technology, and in particular to a medical device residual blood detection kit and its usage method. Background Technology
[0002] In the medical field, the cleaning quality of reusable medical devices directly affects the effectiveness of subsequent disinfection or sterilization, thus impacting the life and health safety of patients. During use, medical devices may become contaminated with organic substances such as blood, pus, and proteins. If cleaning is not thorough, these residues can hinder the effective contact between microorganisms and the sterilization medium, forming a bacterial protective film and causing sterilization methods such as chemical disinfection, gas, steam, hot air, and low-temperature sterilization to fail. Residual blood and other organic substances not only reduce the sterilization effect but may also corrode medical devices, shortening their lifespan.
[0003] Currently, the main method for detecting dirt on the surface of instruments relies on visual inspection, which has significant limitations. It can only detect larger particles of dirt, scale, rust, etc. It is difficult to accurately identify trace amounts of blood residue. Blood residue located in small crevices and inside cavities is often not detected by visual inspection, which can easily lead to instruments that are not thoroughly cleaned entering the subsequent disinfection and sterilization process, increasing the risk of infection. Summary of the Invention
[0004] This invention relates to a medical device residual blood detection kit and its usage method, which solves the problem that the current method mainly relies on human eyes to observe the dirt on the surface of the device, which has obvious limitations. It can only detect some larger particles of dirt, scale, rust, etc., and it is difficult to accurately identify trace amounts of blood residue.

[0007] Furthermore, the movable outer cylinder is rotatably connected to the lower barrel body, the inner bottom side of the movable outer cylinder contacts the outer bottom side of the lower barrel body, the inner top side of the movable outer cylinder contacts the outer side of the upper barrel body, a limit block is provided on the outer side of the lower barrel body, and a sliding hole is provided on the outer side of the movable outer cylinder, with the limit block slidably connected in the sliding hole.
[0008] Furthermore, a slider is provided on the outside of the upper barrel, and a spiral movable hole is provided on the outside of the movable outer cylinder, with the slider slidably connected to the spiral movable hole.
[0009] Furthermore, the movable outer cylinder is symmetrically provided with screw holes on its exterior, and bolts are threaded into the screw holes, with the inner end of the bolts contacting the outer side of the lower cylinder.
[0010] Furthermore, the movable ring is rotatably connected to the bucket lid, and a ring is provided on the top of the bucket lid. A through hole is provided around the inside of the movable ring, and the movable ring slides through the through hole. A spring is fitted on the outside of the ring, with one end of the spring in contact with the bucket lid and the other end of the spring in contact with the movable ring.
[0011] Furthermore, an L-shaped groove is provided around the top of the upper barrel, and a locking block is provided around the outside of the barrel lid. The locking block is connected to the L-shaped groove, and a force-bearing block is provided outside the movable ring. The force-bearing block is connected to the opening of the L-shaped groove.
[0012] This invention discloses a method for using a medical device residual blood detection kit, comprising the following steps:
[0013] 1) First, depending on the size of the medical device, rotate the movable outer cylinder. The slider slides in the spiral movable hole, which drives the upper barrel to move up and down to adjust the internal volume of the barrel, so as to suit the application needs of different sized medical devices.
[0014] 2) After adjusting the upper barrel to the appropriate height, tighten the bolts so that the inner end of the bolts contacts the lower barrel to fix the movable outer cylinder and ensure the stability of the upper barrel.
[0015] 3) Next, place the medical device in the bucket formed by the lower and upper buckets, and pour pure water into the bucket until the medical device is completely submerged.
[0016] 4) Connect the lid to the top of the upper barrel. The locking block is located in the slot of the L-shaped locking groove. Rotate the movable ring so that the bottom of the force block contacts the top of the locking block. Press down on the lid. The locking block moves to the bottom of the L-shaped locking groove, and the force block moves to the slot of the L-shaped locking groove. The lid rotates under the influence of the spring force, so that the locking block moves to the innermost end of the L-shaped locking groove, which has the effect of limiting the lid.
[0017] 5) The bottom of the ultrasonic vibrator is placed in pure water. The ultrasonic waves emitted by the ultrasonic vibrator are conducted in the water, which accelerates the impact of water particles to clean the bloodstains remaining on the medical device, so that the bloodstains dissolve in the pure water.
[0018] 6) After the medical device has been ultrasonically cleaned, rotate the lid in the opposite direction so that the top of the locking block contacts the bottom of the force-bearing block. The spring will then contract under force, allowing you to pull the lid upwards to remove it from the upper barrel. Remove the medical device from the barrel and extract a sample for residual blood stain detection. This completes the entire usage process.
[0019] This invention provides a medical device residual blood detection kit and its method of use, which has the following beneficial effects:
[0020] In use, the medical device is placed in a container consisting of a lower and an upper barrel. Pure water is poured into the container until the medical device is completely submerged. The lid is then attached to the top of the upper barrel. The bottom of the ultrasonic vibrator is positioned in the pure water. The ultrasonic waves emitted by the vibrator are conducted in the water, accelerating the impact of water particles to clean the bloodstains remaining on the medical device, dissolving the bloodstains in the pure water. This allows for the extraction of samples for residual bloodstain detection.
[0021] Furthermore, the vertical guide rod and vertical guide hole slide together to guide the movement of the upper barrel, while the sealing ring seals the sliding connection between the lower and upper barrels. The upper barrel can be adjusted to accommodate different sizes of medical devices, changing its internal volume to better suit the application needs of various medical devices. The limiting block and sliding hole slide together to guide the rotation of the movable outer cylinder. By rotating the movable outer cylinder, the slider slides within the spiral movable hole, driving the upper barrel to move up and down for easy adjustment. After the upper barrel is adjusted to the appropriate height, the bolts are tightened so that the inner end of the bolts contacts the lower barrel, fixing the movable outer cylinder and ensuring the stability of the upper barrel.
[0022] Furthermore, the sliding engagement between the ring and the through hole guides the rotation of the movable ring, while the spring provides elastic reset for the movable ring. When the locking block is located within the L-shaped slot, rotating the movable ring causes the bottom of the force-bearing block to contact the top of the locking block, and pressing down on the lid moves the locking block to the bottom of the L-shaped slot, and the force-bearing block to the opening of the L-shaped slot. The lid rotates under the influence of the spring, causing the locking block to move to the innermost end of the L-shaped slot, thus limiting the lid's position and ensuring the stability of the ultrasonic vibrator. After the medical device has been ultrasonically cleaned, rotating the lid in the opposite direction causes the top of the locking block to contact the bottom of the force-bearing block, causing the spring to contract. This allows the lid to be pulled upwards, removing it from the upper body and taking the medical device out of the container, making the process simpler and more time-saving.

[0042] The vertical guide rod 21 slides and engages with the vertical guide hole 11 to guide the movement of the upper barrel 2. The sealing ring 3 seals the sliding connection between the lower barrel 1 and the upper barrel 2. The upper barrel 2 can be adjusted to accommodate different sizes of medical devices, thereby changing the internal volume and better meeting the application needs of different sized medical devices.
[0043] In this embodiment, the movable outer cylinder 4 is rotatably connected to the lower cylinder 1. The inner bottom side of the movable outer cylinder 4 contacts the outer bottom side of the lower cylinder 1, and the inner top side of the movable outer cylinder 4 contacts the outer side of the upper cylinder 2.

The limit block 12 is slidably connected to the sliding hole 41. A slider 22 is provided on the outside of the upper cylinder 2. A spiral movable hole 42 is provided on the outside of the movable outer cylinder 4. The slider 22 is slidably connected to the spiral movable hole 42.
[0044] The limiting block 12 slides in conjunction with the sliding hole 41 to guide the rotation of the movable outer cylinder 4.

[0048] The sliding engagement between the ring 61 and the through hole 71 guides the rotation of the movable ring 7, while the spring 8 provides an elastic reset for the movable ring 7.

The locking block 62 moves to the bottom of the L-shaped locking groove 23, and the force-bearing block 72 moves to the slot of the L-shaped locking groove 23. The lid 6 rotates under the influence of the spring 8, so that the locking block 62 moves to the innermost end of the L-shaped locking groove 23, which has the effect of limiting the lid 6 and ensuring the stability of the ultrasonic vibrator 9. After the medical device is ultrasonically cleaned, rotate the lid 6 in the opposite direction so that the top of the locking block 62 contacts the bottom of the force-bearing block 72. The spring 8 is compressed by force, and the lid 6 can be pulled up to remove the lid 6 from the upper barrel 2 and the medical device can be taken out of the barrel, which is more convenient and time-saving.
[0051] This invention discloses a method for using a medical device residual blood detection kit, comprising the following steps:
[0052] 1) First, depending on the size of the medical device, rotate the movable outer cylinder 4, and the slider 22 slides in the spiral movable hole 42, which drives the upper barrel 2 to move up and down to adjust the internal volume of the barrel, so as to meet the application needs of different sizes of medical devices.
[0053] 2) After adjusting the upper barrel 2 to a suitable height, tighten the bolt 5 so that the inner end of the bolt 5 contacts the lower barrel 1, which will fix the movable outer cylinder 4 and ensure the stability of the upper barrel 2.
[0054] 3) Next, place the medical device in the bucket formed by the lower bucket 1 and the upper bucket 2, and pour pure water into the bucket until the medical device is completely submerged.
[0055] 4) Connect the lid 6 to the top of the upper barrel 2. The locking block 62 is located in the groove of the L-shaped locking groove 23.

The lid 6 rotates under the influence of the spring 8, so that the locking block 62 moves to the innermost end of the L-shaped locking groove 23, which has the effect of limiting the lid 6.
[0056] 5) The bottom of the ultrasonic vibrator 9 is placed in pure water. The ultrasonic waves emitted by the ultrasonic vibrator 9 are conducted in the water to accelerate the impact of water particles to clean the blood stains remaining on the medical device, so that the blood stains dissolve in the pure water.
