Description

Technical Field

[0001] The present invention relates to the technical field of puncture needle sterilization, and in particular to a high-pressure steam sterilizer for deep abscess puncture needles and a sterilization method thereof. Background Art

[0002] A deep abscess puncture needle is a medical device used for diagnosing and treating deep abscesses. It is used to extract pus through puncture for laboratory tests such as bacterial culture and pus smear to identify the pathogenic bacteria of the abscess and provide a basis for subsequent treatment.

[0003] After sampling, it is usually necessary to sterilize the puncture needle. Existing sterilization methods mainly include ethylene oxide sterilization, high-temperature and high-pressure sterilization, and low-temperature plasma sterilization. In terms of high-temperature and high-pressure sterilization, its sterilization effect is reliable and can effectively kill various microorganisms.

[0004] When existing high-temperature sterilizers are in use, they usually can only provide sufficient steam to the outer surface of the puncture needle, and it is difficult to continuously deliver steam inside the puncture needle, resulting in poor sterilization effect inside the puncture needle.

[0005] In this regard, it can be solved by adjusting the position of the steam nozzle and controlling the steam to directly enter the lumen through the opening of the puncture needle lumen. However, since the steam is in a straight flow state inside the lumen and the flow rate is relatively fast, it is difficult to cover the entire lumen, which may lead to incomplete steam penetration and the formation of sterilization dead corners. Summary of the Invention

[0010] As a further scheme of the present invention: the driven component includes a first guide post arranged in the first piston cylinder, a first piston disc is slidably installed on the first guide post, a first support wheel is arranged on the first piston disc, and the first support wheel is in contact and cooperation with the first arc groove.

[0011] As a further scheme of the present invention: the driven component further includes a first fixing ring arranged on the first guide post, a first spring is sleeved on the first guide post, and two ends of the first spring are respectively abutted against the first piston disc and the first fixing ring.

[0013] As a further scheme of the present invention: the top spraying component includes a second piston cylinder arranged on the sealing cover, a second discharge disc is arranged at the end of the second piston cylinder, the second piston cylinder is rotatably connected with the transmission rod, the second discharge disc is fixedly connected with the second nozzle, a second spiral guide rail is arranged on the second nozzle, a second absorption pipe communicated with the air storage disc is connected to the second piston cylinder, and a second conveying pipe communicated with the second discharge disc is connected to the second piston cylinder.

[0014] As a further solution of the present invention: the opposite pressure mechanism includes a second guide column arranged on the second piston cylinder, the second guide column is provided with a second fixing ring, the second guide column is slidably mounted with a third piston disk, the second guide column is sleeved with a third spring, the two ends of the third spring are respectively abutted against the third piston disk and the second fixing ring, and the second guide column is provided with a guide assembly.

[0016] A high-pressure steam sterilization method for a deep abscess puncture needle comprises the following steps: Step 1: Place multiple puncture needles to be sterilized on a support frame; Step 2: The conveying mechanism works and conveys the steam in the gas storage disk to the first spray head through the first piston cylinder and the bottom spray assembly, so as to spray the steam to one end of the puncture needle; Step 3: The conveying mechanism also drives the pressurized turbulent mechanism to move and adjusts the pressure in the first piston cylinder to continuously adjust the steam injection pressure; Step 4: The conveying mechanism will also drive the opposite pressure-applying mechanism to move, and convey the steam to the second nozzle through the top spraying assembly to spray the steam to the other end of the puncture needle.

[0017] Compared with the prior art, the beneficial effect of the present invention is that the present application can achieve the effect of comprehensive sterilization of the puncture needle by means of two-way pumping air. Specifically, through the cooperation of the conveying mechanism and the pressurized turbulent flow mechanism, it can be achieved by spraying steam through the bottom spraying component and the first nozzle to one end of the puncture needle, and through the movement of the opposing pressure mechanism, it can be achieved that the steam is sprayed through the top spraying component and the second nozzle to the other end of the puncture needle, thereby achieving the effect of two streams of steam impacting turbulence inside the puncture needle, so as to increase the residence time and effective area in the puncture needle.

[0018] The air pressure of the steam sprayed by the first nozzle is in dynamic change and is always higher than the air pressure of the steam sprayed by the second nozzle. Therefore, the impact force of the two steam flows on each other will also change continuously, further promoting a more disordered flow state of the steam inside the puncture needle. Finally, the steam will be discharged from the end of the puncture needle facing the second nozzle, and the discharged steam will impact inside the reflux guide head. Under the action of the reflux guide head, the steam is guided to flow along the inner wall of the reflux guide head and is discharged through the reflux guide head. The discharged steam will impact on the outside of the puncture needle, performing steam sterilization on the outside of the puncture needle. By this way of controlling steam reflux, synchronous sterilization of the inside and outside of the puncture needle by steam can be achieved, ensuring the overall sterilization effect of the puncture needle.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0032] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a high-pressure steam sterilizer for a deep abscess puncture needle includes: A box body 1 and a sealing cover 2 provided on the top of the box body 1. An air storage tray 5 and a support frame 30 are provided in the box body 1, and a first piston cylinder 6 is provided on the sealing cover 2; It further includes: A bottom spraying and feeding assembly disposed on the first piston cylinder 6, and the bottom spraying and feeding assembly includes a first spray head 10; A conveying mechanism is arranged inside the first piston cylinder 6. A pressurizing and turbulent flow mechanism is arranged on the conveying mechanism, and the pressurizing and turbulent flow mechanism can adjust the air supply pressure of the bottom spraying component when the conveying mechanism moves. A top spraying component is arranged on the sealing cover 2. The top spraying component includes a second spray head 24, and a reflux guiding head 2402 is arranged on the second spray head 24. An opposing pressure applying mechanism is arranged on the top spraying component. The opposing pressure applying mechanism can convey steam into the second spray head 24 through the top spraying component when the pressurizing and conveying mechanism moves.

[0033] Specifically, when sterilizing the puncture needle, multiple puncture needles can be placed on the support frame 30, and the head and tail ends of the puncture needles placed on the support frame 30 are exactly in the matching positions with the first spray head 10 and the second spray head 24. At this time, the water in the box body 1 can be heated and evaporated, and the generated steam will enter the air storage tray 5. Under the action of the conveying mechanism, the pressure inside the first piston cylinder 6 is changed, so that the steam in the air storage tray 5 is sprayed through the first spray head 10 to one end of the puncture needle by the bottom spraying component. At the same time, the conveying mechanism will also drive the opposing pressure applying mechanism to move, so as to convey the steam in the air storage tray 5 through the second spray head 24 to the other end of the puncture needle by the top spraying component. The conveying mechanism will also drive the pressurizing and turbulent flow mechanism to move synergistically, so that the air pressure of the steam sprayed by the first spray head 10 is in dynamic change and always remains higher than the air pressure of the steam sprayed by the second spray head 24. This pressure difference causes the steam pressure inside the puncture needle on the side facing the first spray head 10 to be greater than that on the other side.

[0034] When the two steam flows collide with each other, the steam will generate random movement trajectories inside the puncture needle, thus significantly increasing the flow time and flow area of the steam inside the puncture needle. And under the action of the pressure difference, the steam enters the lumen of the puncture needle tube in the form of turbulent flow rather than laminar flow, greatly improving the penetration efficiency of the steam. Finally, the steam will be discharged from the side with smaller pressure and impact inside the reflux guiding head 2402. Under the action of the reflux guiding head 2402, the steam is guided to flow back and impact on the outer wall of the puncture needle, achieving the dual effects of not only comprehensively sterilizing the inside of the puncture needle but also effectively controlling the steam reflux to sterilize the outer wall of the puncture needle, ensuring the overall sterilization effect of the puncture needle.

[0035] Please refer to Figures 3 to 5, the bottom spraying component includes a first discharge disc 9 provided at the end of the first piston cylinder 6. The first discharge disc 9 is fixedly connected to the first nozzle 10. A first spiral guide rail 1001 is provided in the first nozzle 10. A first absorption pipe 7 and a first delivery pipe 8 are connected to the first piston cylinder 6. The first absorption pipe 7 is connected to the air storage disc 5, and the first delivery pipe 8 is connected to the first discharge disc 9.

[0036] Specifically, four one-way valves are installed on the first piston cylinder 6. Two of the one-way valves are connected to the first absorption pipe 7, and the other two one-way valves are connected to the first delivery pipe 8, so that steam can only enter the first piston cylinder 6 through the first absorption pipe 7 and be discharged through the first delivery pipe 8. The air storage disc 5 divides the interior of the box body 1 into two cavities, namely a heating cavity and a sterilization cavity. The heating cavity is used to heat water to generate steam, and the sterilization cavity is used to sterilize the puncture needle. A ventilation hole 501 connected to the heating cavity is provided at the bottom of the air storage disc 5. When the water in the heating cavity is heated into steam, it will enter the air storage disc 5 through the ventilation hole 501. Under the action of the conveying mechanism, the air pressure in the first piston cylinder 6 is reduced, so as to suck the steam in the air storage disc 5 into the first piston cylinder 6 through the first absorption pipe 7. When the air pressure in the first piston cylinder 6 increases, the steam in the first piston cylinder 6 will be conveyed to the first discharge disc 9 through the first delivery pipe 8 and discharged through the first nozzle 10. The exhaust port of the first nozzle 10 is located directly below one of the open ends of the puncture needle. Therefore, the steam will accurately enter the puncture needle through this opening, avoiding steam loss caused by angle deviation. Among them, a first spiral guide rail 1001 is provided in the first nozzle 10. Under the action of the first spiral guide rail 1001, the steam is discharged in a spiral shape and enters the puncture needle, thereby increasing the residence time of the steam inside the puncture needle and making the sterilization effect better.

[0037] Please refer to Figures 1 to 4 , Figure 6 , Figure 7, the conveying mechanism includes a motor 3 disposed on the sealing cover 2. A transmission rod 4 connected to the output shaft of the motor 3 is rotatably installed in the box body 1. A first support ring 12 is disposed at the end of the transmission rod 4. A first arc groove 1201 is formed at the end of the first support ring 12. A driven component is disposed on the first piston cylinder 6. Wherein, the driven component includes a first guide post 11 disposed in the first piston cylinder 6. A first piston disk 13 is slidably installed on the first guide post 11. A first support wheel 14 is disposed on the first piston disk 13. The first support wheel 14 is in abutting cooperation with the first arc groove 1201. The driven component further includes a first fixing ring 1101 disposed on the first guide post 11. A first spring 15 is sleeved on the first guide post 11. Two ends of the first spring 15 are respectively abutted against the first piston disk 13 and the first fixing ring 1101.

[0038] The pressurizing and turbulent flow mechanism includes a second support ring 16 disposed on the transmission rod 4. A second arc groove 1601 is formed on the second support ring 16. A second piston disk 17 is slidably installed on the first guide post 11. A second support wheel 18 in abutting cooperation with the second arc groove 1601 is disposed on the second piston disk 17. A second spring 19 is sleeved on the first guide post 11. Two ends of the second spring 19 are respectively abutted against the second piston disk 17 and the first fixing ring 1101.

[0039] It should be noted that a plurality of first arc grooves 1201 are circumferentially and equidistantly distributed, and the opening specifications are the same. Similarly, a plurality of second arc grooves 1601 are circumferentially and equidistantly distributed, and the number is the same as that of the first arc grooves 1201. The opening sizes of the second arc grooves 1601 are different. Taking one of the second arc grooves 1601 with the smallest size as the starting point, and another second arc groove 1601 at its symmetric position as the end point, the size of the second arc groove 1601 at the end point is the largest, and the sizes of the other second arc grooves 1601 starting from both sides of the starting point to the end point increase in sequence; In the initial state, the first support wheel 14 is located at the most protruding position of the first arc groove 1201, and the second support wheel 18 is located at the most protruding position of the starting point, so that the distance between the first piston disc 13 and the second piston disc 17 is minimized, causing both the first spring 15 and the second spring 19 to be in a compressed state. When the puncture needle needs to be sterilized, at this time, the motor 3 operates and drives the transmission rod 4 to rotate, thereby driving the first support ring 12 and the second support ring 16 to rotate synchronously, so that the position of the first arc groove 1201 relative to the first support wheel 14 changes continuously, and the position of the second arc groove 1601 relative to the second support wheel 18 also changes continuously. Under the action of the first spring 15 and the second spring 19, the first support wheel 14 always fits with the first arc groove 1201, and the second support wheel 18 also remains in contact with the second arc groove 1601. Therefore, the first piston disc 13 and the second piston disc 17 will move in a direction away from each other and move along the length direction of the first guide post 11, causing the pressure in the first piston cylinder 6 to decrease. Under the action of the pressure, steam in the air storage disc 5 is inhaled into the first piston cylinder 6 through the first absorption tube 7; When the first support wheel 14 moves to the most concave position of the first arc groove 1201, the second support wheel 18 also moves to the most concave position of one of the second arc grooves 1601. At this time, the first support ring 12 and the second support ring 16 continue to rotate, and through the first arc groove 1201 and the first support wheel 14, as well as the second arc groove 1601 and the second support wheel 18, the first piston disc 13 and the second piston disc 17 are controlled to move in a direction close to each other, thereby increasing the pressure in the first piston cylinder 6 to deliver the steam to the first discharge disc 9 through the first delivery tube 8.

[0040] Preferably, when the concave position of the next second arc groove 1601 moves to the mating position with the second support wheel 18, due to the difference in the concave amounts of different second arc grooves 1601, the sizes of the negative pressure suction cavities formed in the first piston cylinder 6 are different each time. Therefore, the amount of steam that can be delivered each time also changes accordingly. However, the movement time of the first piston disc 13 and the second piston disc 17 moving close to or away from each other each time remains the same. In this case, the same pumping time is accompanied by different pumping amounts, which will change the pressure of the steam sprayed by the first nozzle 10. Specifically, the steam pressure entering the puncture needle each time will change, causing the steam to flow in a turbulent form inside the puncture needle rather than in a laminar flow. This turbulent state significantly increases the contact opportunity between the steam and the inner wall of the puncture needle, thereby greatly enhancing the sterilization effect on the puncture needle and ensuring the thoroughness and effectiveness of the sterilization process.

[0041] Please refer to Figure 2 、 Figure 3 、 Figure 8 、 Figure 10The top spraying assembly includes a second piston cylinder 20 arranged on the sealing cover 2, a second discharge disk 21 is arranged at the end of the second piston cylinder 20, the second piston cylinder 20 is rotatably connected to the transmission rod 4, the second discharge disk 21 is fixedly connected to the second nozzle 24, the second nozzle 24 is provided with a second spiral guide rail 2401, the second piston cylinder 20 is connected to a second absorption pipe 22 connected to the gas storage disk 5, and the second piston cylinder 20 is connected to a second delivery pipe 23 connected to the second discharge disk 21.

[0042] Furthermore, four one-way valves are also installed on the second piston cylinder 20, two of which are connected to the second absorption tube 22, and the other two are connected to the second delivery tube 23. The second nozzle 24 is in a matching position with the other opening of the puncture needle. When the puncture needle needs to be sterilized, at this time, under the action of the opposing pressure mechanism, the steam in the gas storage disk 5 is sucked into the second piston cylinder 20 through the second absorption tube 22, and is delivered to the second discharge disk 21 through the second delivery tube 23, so that the steam is sprayed into the puncture needle through the other opening of the puncture needle through the second nozzle 24.

[0043] See also Figures 8 to 10 The opposing pressure mechanism includes a second guide column 26 arranged on the second piston cylinder 20, a second fixing ring 2601 is arranged on the second guide column 26, a third piston disc 27 is slidably mounted on the second guide column 26, a third spring 29 is sleeved on the second guide column 26, two ends of the third spring 29 are respectively abutted against the third piston disc 27 and the second fixing ring 2601, a guide assembly is arranged on the second guide column 26, wherein the guide assembly includes a third support ring 25 arranged on the transmission rod 4, a third arc groove 2501 is opened on the third support ring 25, and a third support wheel 28 that abuts against the third arc groove 2501 is arranged on the third piston disc 27.

[0044] Furthermore, the reflux guide head 2402 is arranged in a spherical arc shape, and the inclination angle of the open end of the reflux guide head 2402 faces the direction of the second spray head 24. The size and the number of the third arc grooves 2501 are the same as those of the first arc grooves 1201. In the initial state, the third support wheel 28 abuts against the most protruding position of the third arc groove 2501, so that the third piston disk 27 is located at the end of the stroke towards the second discharge disk 21, so that the third spring 29 is in a compressed state. When the transmission rod 4 rotates, it drives the third support ring 25 to rotate, so that the abutting position between the third arc groove 2501 and the third support wheel 28 changes continuously. Under the action of the third spring 29, the third support wheel 28 and the third arc groove 2501 are always in an abutting state controlled by the third piston disk 27. The third piston disk 27 will move along the length direction of the second guide post 26, so that the air pressure in the second piston cylinder 20 decreases, and thus the steam in the air storage disk 5 is sucked into the second piston cylinder 20 through the second absorption pipe 22. When the third support wheel 28 is located at the most concave position of the third arc groove 2501, the displacement of the third piston disk 27 reaches the maximum. At this time, the third support ring 25 continues to rotate, so that the third piston disk 27 moves towards the initial position to convey the steam in the second piston cylinder 20 to the second discharge disk 21 through the second delivery pipe 23. The steam will be sprayed into the puncture needle through the second spray head 24.

[0045] Preferably, through the two-way pumping operation of the first spray head 10 and the second spray head 24, the steam can be supplied to both ends of the puncture needle simultaneously. The two streams of steam entering from both ends of the puncture needle will impact each other and move randomly inside the puncture needle, thereby significantly increasing the residence time and the acting area of the steam inside the puncture needle, enabling the steam to fully contact the inner wall of the puncture needle and improving the sterilization effect.

[0046] Meanwhile, the air pressure of the steam sprayed by the first spray head 10 is in dynamic change and is always higher than the air pressure of the steam sprayed by the second spray head 24. Therefore, the impact force between the two streams of steam will also change continuously, further promoting a more disordered flow state of the steam inside the puncture needle. Finally, the steam will be discharged from the end of the puncture needle facing the second spray head 24, and the discharged steam will impact inside the reflux guide head 2402. Under the action of the reflux guide head 2402, the steam is guided to flow along the inner wall of the reflux guide head 2402 and is discharged through the reflux guide head 2402. The discharged steam will impact on the outside of the puncture needle to perform steam sterilization treatment on the outside of the puncture needle. By this way of controlling the steam reflux, the synchronous sterilization treatment of the inside and outside of the puncture needle can be realized, ensuring the overall sterilization effect of the puncture needle.

[0047] A high-pressure steam sterilization method for a deep abscess puncture needle includes the following steps: Step 1: Place multiple puncture needles to be sterilized on the support frame 30; Step 2: The conveying mechanism operates, and conveys the steam in the air storage disc 5 to the first nozzle 10 through the first piston cylinder 6 and the bottom spraying assembly, so as to spray the steam to one end of the puncture needle; Step 3: The conveying mechanism also drives the pressurizing and turbulent flow mechanism to move, and adjusts the pressure in the first piston cylinder 6, so as to continuously adjust the steam spraying pressure; Step 4: The conveying mechanism also drives the opposing pressure mechanism to move, and conveys the steam to the second nozzle 24 through the top spraying assembly, so as to spray the steam to the other end of the puncture needle.
