Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of instrument disinfection, in particular to a disinfection device for vascular surgical instruments. BACKGROUND

[0002] Tube surgical instruments are special medical instruments used for thoracic and cardiovascular surgery, which are divided into knives, scissors, pliers, tweezers, clamps, hooks, needles and other instruments according to functions. These medical instruments need to be disinfected in time after use to kill microorganisms on the instruments through disinfection, so as to ensure that they reach a sterile state, thereby preventing infection, ensuring patient safety and maintaining medical quality.

[0003] The disinfection of surgical instruments generally adopts steam disinfection. High-temperature saturated steam (usually 121℃-135℃) can quickly penetrate the complex structure of the instrument (such as the lumen, joint gap), ensuring that the proteins and nucleic acids of microorganisms (including spores, viruses) are completely denatured and inactivated.

[0004] However, in the actual disinfection process, due to the characteristics of hot air rising, part of the steam will overflow and rise from the four sides of the disinfection basket containing the instruments during the upward movement of the hot steam from the bottom of the disinfection cabinet due to the obstruction of multiple layers of instruments. At the same time, the steam contacts the bottom of the instrument more frequently when it rises, and cannot directly contact the top of the instrument. Only when the inside of the disinfection box is completely filled with steam, the top of the instrument will be in contact with the steam, thus prolonging the disinfection cycle of the instrument. In order to maintain the dryness inside the disinfection cabinet, the top of the disinfection cabinet is generally equipped with a circulating system to re-introduce the steam reaching the top into the steam generation unit for secondary heating, which results in a short residence time of the steam in the disinfection cabinet, thereby greatly reducing the disinfection effect of the steam on the top of the instrument. SUMMARY

[0005] The purpose of the present application is to solve the problem of the traditional disinfection equipment that the steam rises from the side of the instrument during the steam disinfection process, which reduces the contact area and contact time of the steam with the instrument, resulting in an increase in the disinfection cycle and a decrease in the disinfection effect.

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0048] As Figures 1-5As shown, the present application provides a sterilization device for vascular surgical instruments: comprising a cabinet 10 and a hinged door 11 at the front end thereof, the bottom of the cabinet 10 is provided with a steam generating unit 12, and the inside of the cabinet 10 is provided with a sterilization basket 13 for loading instruments, the sterilization basket 13 comprises a main beam 131, the upper end of the main beam 131 is fixedly connected with a first reinforcing beam 133, and the upper end of the first reinforcing beam 133 is provided with a second reinforcing beam 134, the periphery of the main beam 131 is fixedly connected with a guardrail 132, the inside of the cabinet 10 is fixedly connected with a positioning frame 14, and the positioning frame 14 is movably connected between the sterilization basket 13, and the inside of the cabinet 10 is fixedly connected with a circulating pipeline 15, further comprising a guide assembly 20 for precise sterilization in the inside of the cabinet 10.

[0049] The guide assembly 20 comprises a main air guide pipe 21 fixedly connected to the inside of the cabinet 10, and the surface of the main air guide pipe 21 is provided with an air guide hole 22, the main air guide pipe 21 is provided with a secondary air guide pipe 25, and the lower end of the secondary air guide pipe 25 is rotatably connected with an air outlet pipe 27 through a movable seat 26, the surface of the air outlet pipe 27 is provided with a first air outlet hole 28 and a second air outlet hole 29, the surface of the main air guide pipe 21 is fixedly connected with a fixed frame 23, and the secondary air guide pipe 25 is clamped on the fixed frame 23 through a fixed seat 24.

[0050] Specifically, first, the instruments to be disinfected are placed in the disinfection basket 13, and the disinfection basket 13 is hung on the positioning frame 14, then the cabinet door 11 is closed, and then the steam generation unit 12 is started, the steam generated by the steam generation unit 12 enters the main air guide pipe 21, and then enters the inside of the auxiliary air guide pipe 25 through the air guide hole 22, and then the steam enters the inside of the movable seat 26 and spreads into the air outlet pipe 27, and then the steam is discharged through the first air outlet hole 28 and the second air outlet hole 29 on the surface of the air outlet pipe 27, because the diameters of the first air outlet hole 28 and the second air outlet hole 29 are greatly reduced compared with the diameter of the air outlet pipe 27, the upstream pressure will be forced to rise to maintain the flow balance after the outlet area is reduced, and this pressure rise will directly cause the outlet flow rate to increase, so that the steam is discharged from the first air outlet hole 28 and the second air outlet hole 29 in a jet shape, so that the generated steam quickly contacts the instruments, improves the disinfection efficiency of the instruments, and the discharged steam simultaneously disinfects the upper and lower parts of the instruments, increases the contact area of the steam and the instruments, and greatly improves the disinfection effect. In addition, when the steam is discharged through the second air outlet hole 29, because the second air outlet hole 29 is diagonally symmetric front and back, and the movable seat 26 is connected with the auxiliary air guide pipe 25 through the bearing, and the pressure generated by the steam is huge, therefore the steam discharged through the second air outlet hole 29 will push the movable seat 26 to drive the air outlet pipe 27 to rotate, the rotation of the air outlet pipe 27 increases the contact range of the steam when it is discharged with the instruments in the disinfection basket 13, further improving the disinfection effect of the instruments, and then the steam continues to rise in the cabinet 10, when the steam reaches the top of the cabinet 10, the steam is guided into the inside of the steam generation unit 12 through the circulating pipeline 15 by using the circulating system to be reheated, avoiding the continuous generation of steam in the cabinet 10 to cause the pressure to be too large, also reducing the probability of the steam condensing into water to cause the humidity in the cabinet 10 to be too large, and guaranteeing the disinfection effect of the instruments.

[0051] As shown in Figure 6 The inside of the air outlet pipe 27 is provided with a dehumidification assembly 30 for removing water in the steam; the dehumidification assembly 30 includes a limiting rod 31 fixedly connected to the inside of the air outlet pipe 27, a movable disc 32 slidably connected to the outside of the limiting rod 31, a non-woven fabric 33 fixedly connected between one side of the movable disc 32 and one end of the air outlet pipe 27, a first spring 34 rotatably connected between the other side of the movable disc 32 and the other end of the air outlet pipe 27, a sliding groove 35 formed on the surface of the limiting rod 31, and a sliding block matched with the sliding groove 35 provided on the inner circular surface of the movable disc 32.

[0052] The movable disc 32 and the air outlet pipe 27 can perform piston motion, and the thickness of the movable disc 32 is greater than the diameter of the first air outlet hole 28 and the second air outlet hole 29; the non-woven fabric 33 is in the shape of a cylindrical tube, and the inner wall of one end of the non-woven fabric 33 and the air outlet pipe 27 are both inclinedly arranged towards the center of the cabinet 10.

[0053] Specifically, when the steam enters the inside of the air outlet pipe 27, it will pass through the non-woven fabric 33, which is in a curled state in the initial state. After the steam enters the inside of the air outlet pipe 27, it will first pass through one end of the non-woven fabric 33 to the position of the movable disc 32 and push the movable disc 32 to displace along the surface of the limiting rod 31 inside the air outlet pipe 27. With the movement of the movable disc 32, the slider on the inner surface thereof synchronously slides inside the sliding groove 35. Since the sliding groove 35 is spiral-shaped, the slider will drive the movable disc 32 to rotate when it moves, so as to make the originally curled non-woven fabric 33 expand to a cylindrical shape by the rotation of the movable disc 32. When the steam is discharged from the first air outlet hole 28 and the second air outlet hole 29, it is first filtered by the non-woven fabric 33, which absorbs the moisture in the steam, thereby reducing the water content in the steam. Thus, the condensation of steam into water droplets and the secondary breeding of bacteria on the instruments due to high water content after the sterilization of the instruments by the steam are avoided, and the sterilization effect on the instruments is ensured. After the sterilization is completed, the steam stops entering the air outlet pipe 27. At this time, the movable disc 32 is reset under the pushing of the first spring 34. When the movable disc 32 is reset, it rotates to twist the non-woven fabric 33 into a curled state again, so as to squeeze out the moisture absorbed by the non-woven fabric 33, so that the non-woven fabric 33 remains relatively dry, facilitating the continuous moisture filtration of the non-woven fabric 33 on the steam. Since the non-woven fabric 33 and the inner wall of one end of the air outlet pipe 27 are both inclinedly arranged towards the center of the cabinet 10, the squeezed-out moisture will flow into the inside of the movable seat 26, and then the movable seat 26 is removed to pour out the water.

[0054] As Figures 2-4 and Figure 8 and Figure 9 As shown in the drawings, the inside of the cabinet 10 is provided with a swing assembly 40. The swing assembly 40 includes a limiting box 41 fixedly connected to the positioning frame 14, and an activity plate 42 for connecting the sterilization basket 13 movably connected inside the limiting box 41. The second spring 43 is fixedly connected between the activity plate 42 and the limiting box 41. The sterilization basket 13 is provided with a magnetic plate 44 on both sides thereof. The air outlet pipe 27 is fixedly connected with a magnetic block 45 at one end away from the movable seat 26.

[0055] The magnetic block 45 and the magnetic plate 44 are magnetically attracted to each other, and the magnetic force between the magnetic block 45 and the magnetic plate 44 is greater than the elastic force of the second spring 43. The elastic force of the second spring 43 is greater than the weight borne by the activity plate 42.

[0056] Specifically, cooperate with the rotation of the movable seat 26 when disinfecting, when the movable seat 26 drives the air outlet pipe 27 to rotate to the left and right distribution, the magnetic block 45 at the end of the air outlet pipe 27 will generate magnetic attraction to the magnetic plate 44 on both sides of the disinfection basket 13, thereby pulling the magnetic plate 44 to move downward by magnetic force, the magnetic plate 44 moves downward to drive the disinfection basket 13 to move downward synchronously, so that the disinfection basket 13 pushes the movable plate 42 to move downward inside the limiting box 41, and then the movable seat 26 drives the air outlet pipe 27 to rotate to the front and rear distribution, at this time the magnetic block 45 is separated from the magnetic plate 44, after losing the magnetic attraction, the movable plate 42 is pushed upward by the second spring 43 to make the disinfection basket 13 return to the original position, so reciprocating, so that the disinfection basket 13 is in an up-and-down swinging state during disinfection, and the inertia generated by the up-and-down swinging of the disinfection basket 13 can shake off the water droplets attached to the surface of the instrument, so as to avoid the water droplets attached to the surface of the instrument to make the instrument too wet, further guaranteeing the dryness of the instrument after disinfection and improving the disinfection effect of the instrument.

[0057] As shown in Figure 2 , Figure 4 , Figure 7 , Figure 9 and Figure 10 , the disinfection basket 13 and the magnetic plate 44 are provided with a turnover assembly 50, the turnover assembly 50 includes a limiting ring 51 fixedly connected to the top of the first reinforcing beam 133 for connecting the second reinforcing beam 134, the two ends of the second reinforcing beam 134 are fixedly connected with gear wheels 52, the surface of the magnetic plate 44 is provided with a first limiting groove 53 and a second limiting groove 55, the inner wall of the first limiting groove 53 is provided with a gear slot 54 engaged with the gear wheel 52, and the second limiting groove 55 is provided with a third spring 56 fixedly connected with the main beam 131.

[0058] Specifically, cooperate with the magnetic attraction of the magnetic block 45 to the magnetic plate 44, when the magnetic plate 44 is magnetically attracted, it will slide downward along the main beam 131 by the second limiting groove 55, at this time, with the downward movement of the magnetic plate 44, the gear slot 54 in the inner wall of the first limiting groove 53 drives the gear wheel 52 engaged therewith to rotate, so as to drive the second reinforcing beam 134 to rotate inside the limiting ring 51, and change the contact position between the instrument and the second reinforcing beam 134 when the second reinforcing beam 134 rotates, thereby further improving the disinfection range of the instrument, so as to avoid the position of the instrument being blocked to reduce the disinfection effect, and then when the magnetic plate 44 is reset, the second reinforcing beam 134 is driven to rotate by driving the gear wheel 52 to rotate, so that the instrument in the disinfection basket 13 is loosened, so that the contact surface of the instrument exposed when the instrument is stacked is exposed, and the disinfection range is further improved.

[0059] As shown in Figure 2 and Figure 11As shown, the interior of the cabinet body 10 is provided with an anti-scalding assembly 60, which comprises a storage box 61 fixedly connected to the interior of the cabinet body 10, and the interior of the storage box 61 is movably connected with a piston seat 62, the interior of the piston seat 62 is movably connected with a piston plate 63, the fourth spring 64 penetrating through the piston seat 62 is fixedly connected between the piston plate 63 and the cabinet body 10, the lower end of the movable seat 26 is movably connected with a winding shaft 69 through a damping bearing, the traction rope 66 penetrating through the piston plate 63 and the storage box 61 is fixedly connected between the piston seat 62 and the winding shaft 69, the through hole 68 is formed on the surface of the piston plate 63, the one-way valve 67 is fixedly connected to the front end of the storage box 61, and the fifth spring 65 is fixedly connected between the piston plate 63 and the piston seat 62.

[0060] Specifically, during the disinfection, the rotation of the movable seat 26 drives the winding shaft 69 to rotate synchronously, and the traction rope 66 is wound on the surface of the winding shaft 69 when the winding shaft 69 rotates, so as to pull the piston plate 63 and the piston seat 62 to move forward in the storage box 61, at this time, the piston plate 63 and the piston seat 62 are separated, and after the piston plate 63 contacts with the inner wall of the front end of the storage box 61, the piston seat 62 continues to move forward under the pulling of the traction rope 66, until the piston seat 62 is clamped outside the piston plate 63, and after the traction rope 66 is completely wound on the surface of the winding shaft 69, if the movable seat 26 is still rotating, at this time, the winding shaft 69 will relatively rotate with the movable seat 26 through the damping bearing, so as to avoid that the traction rope 66 is pulled off due to continuous pulling force, and to prevent that the traction rope 66 causes resistance to the rotation of the movable seat 26, after the disinfection is completed and the steam no longer drives the movable seat 26 to rotate, the fourth spring 64 pulls the piston seat 62 to reset, and since the piston plate 63 is clamped inside the piston seat 62, the through hole 68 on the surface of the piston plate 63 is also blocked, so that the piston plate 63 and the piston seat 62 form a sealed whole to move backward in the storage box 61, so as to suck the high-temperature steam in the cabinet body 10 into the interior of the storage box 61 through the one-way valve 67, until the fourth spring 64 no longer applies backward pulling force to the piston plate 63 after completely resetting, at this time, the fifth spring 65 resets to push the piston plate 63 to move forward and separate from the piston seat 62, at this time, the through hole 68 on the surface of the piston plate 63 is opened, so that the piston plate 63 and the piston seat 62 are not affected by the air pressure resistance when moving forward again, and the high-temperature steam in the cabinet body 10 is quickly sucked away after the disinfection is completed, so as to avoid that the high-temperature steam rushes out when the cabinet door 11 is opened, causing personnel scalding, and to ensure the disinfection effect and the safety of the disinfection operation.

[0061] Working principle: first, the instruments to be disinfected are placed in the disinfection basket 13, and the disinfection basket 13 is hung on the positioning frame 14, then the cabinet door 11 is closed, and then the steam generating unit 12 is started, the steam generated by the steam generating unit 12 enters the main air duct 21, and then enters the inside of the auxiliary air duct 25 through the air hole 22, then the steam enters the inside of the movable seat 26 and spreads to the air outlet pipe 27, then the steam is discharged through the first air outlet hole 28 and the second air outlet hole 29 on the surface of the air outlet pipe 27, because the diameter of the first air outlet hole 28 and the second air outlet hole 29 is greatly reduced compared with the diameter of the air outlet pipe 27, the upstream pressure will be forced to rise to maintain the flow balance after the outlet area is reduced, this pressure rise will directly lead to the outlet flow rate to increase, so that the steam is discharged from the first air outlet hole 28 and the second air outlet hole 29 in a jet shape, so that the generated steam quickly contacts the instruments, improves the disinfection efficiency of the instruments, and the discharged steam simultaneously disinfects the upper and lower parts of the instruments, increases the contact area of the steam and the instruments, and greatly improves the disinfection effect, in addition, when the steam is discharged through the second air outlet hole 29, because the second air outlet hole 29 is diagonally symmetrical front and back, and the movable seat 26 is connected with the auxiliary air duct 25 through the bearing, and the pressure generated by the steam is huge, therefore the steam discharged through the second air outlet hole 29 will drive the movable seat 26 to drive the air outlet pipe 27 to rotate, the rotation of the air outlet pipe 27 increases the contact range of the steam with the instruments in the inside of the disinfection basket 13 when the steam is discharged, further improves the disinfection effect of the instruments, then the steam continues to rise in the inside of the cabinet 10, when the steam reaches the top of the cabinet 10, the steam is introduced into the inside of the steam generating unit 12 through the circulating pipeline 15 by using the circulating system to be reheated, avoiding the continuous generation of steam in the inside of the cabinet 10 to cause the pressure to be too large, also reducing the probability of the steam condensing into water to cause the humidity in the inside of the cabinet 10 to be too large, guaranteeing the disinfection effect of the instruments.
