Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and aims to design a surgical instrument post-sterilization packaging device used by a hospital sterilization supply center, so as to improve the instrument packaging efficiency and packaging sealing while maintaining cleanliness, accelerate the surgical instrument to enter the next sterilization link, and thereby improve the overall sterilization supply speed of the surgical instrument in the sterilization supply center. Background Art

[0002] Surgical instruments are tools and equipment used for surgery and diagnosis in medical institutions. According to their different functions and uses, surgical instruments can be divided into cutting instruments (scalpels, surgical scissors, scrapers, etc.), suturing instruments (needles and threads, suture needles, staplers, tweezers, etc.), clamping instruments (vascular clamps, vascular clamps, intestinal clamps, tissue clamps, etc.), and suction instruments (suction tubes, aspirators, etc.); after surgical instruments are used, in order to be used again, surgical instruments must be disinfected first (kill pathogenic microorganisms), and further sterilized after disinfection (inactivate all microorganisms including spores); disinfection is usually carried out by ultrasonic cleaning, manual cleaning, chemical disinfection, automatic cleaning and disinfection machines, etc., and sterilization is usually carried out by pressure steam sterilization, low-temperature plasma sterilization, ethylene oxide sterilization, etc.; therefore, disinfection and sterilization procedures are the core links of the pre-use treatment of surgical instruments, and effective disinfection, clean packaging, and packaging airtightness will directly affect the subsequent sterilization quality.

[0003] The Central Sterile Supply Department (CSSD) is a department in the hospital that is responsible for the cleaning, disinfection and sterilization of all reusable medical instruments, instruments and items in various departments. The quality of its work is directly related to the life safety of patients and is also an important factor affecting the level of hospital infection management and the efficiency of diagnosis and treatment. After the surgical instruments are disinfected by the CSSD, they need to be packaged in bags so that they can enter the next sterilization link. Ultraviolet sterilization is a pre-packaging treatment for surgical instruments to prevent bacteria in the air from being entrained into the packaging bag during the transportation of surgical instruments. The key factor for ultraviolet lamp sterilization is the superposition of specific wavelength ultraviolet rays and suitable ambient temperature. During operation, due to the continuous outward heat emission, the temperature of the ultraviolet lamp is difficult to be constant at the optimal sterilization temperature, resulting in a decrease in its sterilization efficiency. In addition, after the packaging bag containing sterilized surgical instruments is hot-melt sealed, it is difficult to accurately detect the air tightness of the packaging bag due to the shape of the instrument. How to improve the automation level of CSSD as much as possible under the premise of ensuring medical safety, and to achieve automatic packaging, clean packaging and self-testing of surgical instruments after disinfection is an important topic of concern to CSSD staff.

An ultraviolet lamp 49 is installed inside the mounting seat 47. The ultraviolet lamp 49 emits ultraviolet rays outward to sterilize the medical instruments in the packaging bag. The air is circulated through the air guide holes 48 to take away the heat generated by the ultraviolet lamp 49 when it emits light. A lampshade 410 is installed on the outer wall of the mounting seat 47 to form a closed space. An air cover 411 is installed on the rear side wall of the mounting seat 47 at the rear side. The other end of the second air pipe 46 penetrates the inner surface of the first bracket 41 and is connected to the rear side of the air cover 411. A plurality of air guide holes 48 are distributed with the center line of the ultraviolet lamp 49 as the center, so that the airflow passes through the ultraviolet lamp 49 evenly, so that the ultraviolet lamp 49 dissipates heat evenly. The temperature sensing component 43 includes a heating seat 431 embedded in the top of the inner side of the first bracket 41. The inner cavity of the heating seat 431 is filled with kerosene liquid 432. A limiting cylinder 433 is vertically installed at the center of the upper surface of the heating seat 431. A piston 434 that can slide up and down is inserted into the inner cavity of the limiting cylinder 433. The heating seat 431 heats up with the heat of the ultraviolet lamp 49. The volume of the kerosene liquid 432 increases with the temperature, which causes the piston 434 to rise. The kerosene liquid 432 has a large thermal expansion coefficient and has a strong effect on driving the piston 434 to move. A rack 435 is vertically installed on the top of the piston 434.

A pressure plate 53 is installed at the output end of the first cylinder 52, and a heating strip 54 is embedded in the bottom of the pressure plate 53. The pressure plate 53 is driven by the first cylinder 52 to rise or fall, and the position of the heating strip 54 corresponds to the pad 3. When the heating strip 54 descends to squeeze the packaging bag, the heating strip 54 is energized to generate heat to hot-melt seal the packaging bag.

[0021] As a preferred solution, further, the air leakage detection mechanism 6 includes a third bracket 61 installed on the right side of the top of the conveyor 2, and the second cylinder 62 is installed at both ends of the upper surface of the third bracket 61. A controller 63 is installed on the front of the third bracket 61, and a support plate 64 is installed at the output end of the second cylinder 62. A camera 65 electrically connected to the controller 63 is installed on the right side of the support plate 64. The controller 63 analyzes the impact of the camera 65 shooting. A plurality of feathers 66 are inserted from front to back on the lower surface of the support plate 64, and the feathers 66 are located on the left side of the camera 65. The camera 65 shoots at an angle pointing to the feathers 66 to shoot whether the feathers 66 are deformed to determine whether there is air leakage after the packaging bag is sealed. The feathers 66 are used to test the airflow from left to right. The left side of the lower surface of the support plate 64 is evenly installed with an extrusion component 67; The extrusion assembly 67 includes a telescopic cylinder 671 vertically mounted on the lower surface of the support plate 64. The inner cavity of the telescopic cylinder 671 is respectively connected with a spring 672 and a telescopic rod 673 from top to bottom. The spring 672 pushes the telescopic rod 673 downward, and an extrusion block 674 is installed at the bottom of the telescopic rod 673. As a preferred solution, further, the material guiding mechanism 7 includes two support rods 71 ​​vertically installed at the front and rear ends of the right side of the bottom of the conveyor 2, and the right end of the support rod 71 is equipped with a second rotating shaft 72 that can rotate around its own axis through a bearing, and a guide plate 73 is installed on the outer wall of the second rotating shaft 72. The guide plate 73 plays a conducting role for the packaging bag, and a rocker rod 74 is installed at the front end of the second rotating shaft 72. The guide plate 73 and the rocker rod 74 can rotate simultaneously through the second rotating shaft 72, and a slideway 75 is provided on the side of the front of the rocker rod 74 away from the second rotating shaft 72. A third cylinder 76 is vertically installed on the outer wall of the support rod 71 on the front side, and the third cylinder 76 is electrically connected to the controller 63, and a roller 77 plugged into the inner cavity of the slideway 75 is installed at the output end of the third cylinder 76. When the third cylinder 76 drives the roller 77 to rise or fall, the roller 77 slides in the slideway 75, and can drive the second rotating shaft 72 to rotate clockwise or counterclockwise.

[0022] Working principle: Step 1: Place the packaging bag containing the medical device on the conveyor 2, and the sealing position of the packaging bag is on the pad 3. The conveyor 2 conveys the packaging bag from left to right. When passing through the disinfection mechanism 4, the ultraviolet lamp 49 releases ultraviolet rays outward, and the ultraviolet rays pass through the lampshade 410 and irradiate the medical device to sterilize and disinfect the medical device. Step 2: As the ultraviolet lamp 410 continues to work, the heat generated gradually increases, prompting the heated seat 431 to absorb heat, the kerosene liquid 432 absorbs heat and expands, and the extrusion piston 434 rises along the inner wall of the limiting cylinder 433. At the same time, the rack 435 drives the gear 443 to rotate clockwise, allowing the first rotating shaft 442 to drive the valve core 446 to rotate clockwise, and the conductive area between the exhaust hole 447 and the through hole 445 increases, expanding the airflow brought by the fan 42, and the airflow passes through the air guide hole 48. The airflow around the ultraviolet lamp 49 takes away the heat, thereby cooling the ultraviolet lamp 49; As the temperature decreases, the volume of the kerosene liquid 432 gradually decreases, the piston 434 descends under the gravity of the rack 435, the valve core 446 rotates counterclockwise, the communicating area between the exhaust hole 447 and the through hole 445 gradually decreases, and the air flow rate is reduced. Therefore, the ultraviolet lamp 49 can be automatically temperature-controlled, so that the ultraviolet lamp 49 can work at the optimal working temperature; Step 3: After the packaging bag is sterilized, the first cylinder 52 drives the pressing plate 53 to move downward, and the heating strip 54 presses the packaging bag onto the pad 3. The heating strip 54 is powered on to increase the temperature, and the packaging bag is hot-melt sealed; Step 4: When the sealed packaging bag reaches directly below the air leakage detection mechanism 6, the second cylinder 62 drives the support plate 64 to move downward, allowing the squeezing block 674 to gradually approach the packaging bag. Since the elastic force of the spring 672 squeezes the telescopic rod 673, the squeezing block 674 can squeeze the packaging bag. If the packaging bag is sealed intact, the feather 66 is stationary, and the packaging bag leaks, the airflow will blow the feather 66 to deform, and the camera 65 takes a picture of the feather 66. The controller 63 determines whether the packaging bag is intact by analyzing the image. Step 5. For qualified packaging bags, the guide plate 73 can be pressed to slide to the right. For unqualified packaging bags, the controller 63 shrinks the third cylinder 76. While the roller 77 slides in the slide 75, the swing rod 74 drives the guide plate 73 to swing clockwise. The guide plate 73 tilts in the opposite direction, and the packaging bag slides to the left, thereby realizing the leakage detection and screening of the packaging bags.
