Description

Technical Field

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

[0002] The deep abscess puncture needle is a medical device used to diagnose and treat deep abscesses. It extracts pus through puncture for laboratory examination, such as bacterial culture and pus smear, to identify the pathogen of the abscess and provide a basis for subsequent treatment.

[0003] After sampling is completed, the puncture needle usually needs to be sterilized. Existing sterilization methods are mainly through ethylene oxide sterilization, high temperature and high pressure sterilization, low temperature plasma sterilization, etc. As for high temperature and high pressure sterilization, its sterilization effect is reliable and can effectively kill various microorganisms.

[0004] When used, existing high-temperature sterilizers can usually 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] This can be solved by adjusting the position of the steam nozzle and controlling the steam to enter the lumen directly through the opening of the puncture needle lumen. However, since the steam is in a linear flow state in the lumen and the flow rate is fast, it is difficult to spread throughout the entire lumen, which may cause incomplete steam penetration and form a sterilization dead corner.

[0021] As a further solution of the present invention: the opposing pressure mechanism includes a second guide column arranged on the second piston cylinder, a second fixing ring is provided on the second guide column, a third piston disc is slidably mounted on the second guide column, a third spring is sleeved on the second guide column, two ends of the third spring are respectively abutted against the third piston disc and the second fixing ring, and a guide assembly is provided on the second guide column.

[0023] A high-pressure steam sterilization method for a deep abscess puncture needle comprises the following steps:

[0024] Step 1: Place multiple puncture needles to be sterilized on the support frame;

[0028] 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 bidirectional pumping. Specifically, through the cooperation of the conveying mechanism and the pressurized turbulent flow mechanism, it is possible to spray steam into one end of the puncture needle through the bottom spraying component and the first nozzle, and through the movement of the opposing pressure mechanism, it is possible to spray steam into the other end of the puncture needle through the top spraying component and the second nozzle, thereby achieving the effect of two streams of steam impacting turbulence inside the puncture needle, thereby increasing the residence time and effective area in the puncture needle.

[0029] 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 force of the two steam impacting each other will also change continuously, further causing the steam to produce a more turbulent flow state inside the puncture needle. Eventually, the steam will be discharged from the puncture needle toward one end of the second nozzle, and the discharged steam will impact 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 discharged through the reflux guide head. The discharged steam will impact the outside of the puncture needle, and the outside of the puncture needle will be steam sterilized. By controlling the steam reflux in this way, the 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 DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0043] See also Figures 1 to 10 In an embodiment of the present invention, a high-pressure steam sterilizer for a deep abscess puncture needle comprises:

[0044] A box body 1, and a sealing cover 2 arranged on the top of the box body 1, an air storage disk 5 and a support frame 30 are arranged in the box body 1, and a first piston cylinder 6 is arranged on the sealing cover 2;

[0045] Also includes:

[0046] A bottom spraying assembly is provided on the first piston cylinder 6, and the bottom spraying assembly includes a first spray head 10;

[0047] A conveying mechanism is provided in the first piston cylinder 6, and a pressurizing and turbulent flow mechanism is provided on the conveying mechanism, and the pressurizing and turbulent flow mechanism can adjust the air supply pressure of the bottom end spraying assembly when the conveying mechanism moves;

[0048] A top spraying assembly is provided on the sealing cover 2, and the top spraying assembly includes a second spray head 24, and a reflux guide head 2402 is provided on the second spray head 24;

[0049] The opposite pressure-applying mechanism is provided on the top spraying assembly, and the opposite pressure-applying mechanism can deliver steam to the second nozzle 24 through the top spraying assembly when the conveying mechanism moves.

[0050] Specifically, when sterilizing puncture needles, multiple puncture needles can be placed on the support frame 30, with the corresponding ends of the puncture needles on the support frame 30 precisely aligned with the first nozzle 10 and the second nozzle 24. At this time, the water in the box 1 can be heated and evaporated, and the generated steam will enter the gas storage disk 5. Under the action of the conveying mechanism, the pressure in the first piston cylinder 6 is changed, so that the steam in the gas storage disk 5 is sprayed through the first nozzle 10 to one end of the puncture needle through the bottom spray assembly. At the same time, the conveying mechanism also drives the opposing pressure-applying mechanism to move, so that the steam in the gas storage disk 5 is transported through the second nozzle 24 to the other end of the puncture needle through the top spray assembly. The conveying mechanism also drives the pressurization and turbulence mechanism to move in coordination, so that the pressure of the steam sprayed by the first nozzle 10 is in a dynamic state and always remains higher than the pressure of the steam sprayed by the second nozzle 24. This pressure difference causes the steam pressure inside the puncture needle facing the first nozzle 10 to be greater than the steam pressure on the other side.

[0051] When the two streams of steam collide, they produce irregular motion paths within the needle, significantly increasing the steam's flow time and area within the needle. Furthermore, due to the pressure differential, the steam enters the needle lumen in a turbulent rather than laminar flow, greatly improving its penetration efficiency. Ultimately, the steam is discharged from the side with lower pressure and impacts the reflux guide 2402. Under the action of the reflux guide 2402, the steam is guided back and impacts the outer wall of the needle, achieving the dual effects of fully sterilizing the interior of the needle while effectively controlling steam reflux and sterilizing the outer wall of the needle, ensuring the overall sterilization of the needle.

[0052] See also Figure 3-Figure 5The bottom spraying assembly includes a first discharge disk 9 arranged at the end of the first piston cylinder 6, the first discharge disk 9 is fixedly connected to the first nozzle 10, a first spiral guide rail 1001 is provided in the first nozzle 10, and the first piston cylinder 6 is connected to the first absorption pipe 7 and the first delivery pipe 8, the first absorption pipe 7 is connected to the gas storage disk 5, and the first delivery pipe 8 is connected to the first discharge disk 9.

[0053] In detail, four one-way valves are installed on the first piston cylinder 6, two of which 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 disk 5 divides the interior of the box 1 into two cavities, namely the heating cavity and the 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 vent 501 connected to the heating cavity is provided at the bottom of the air storage disk 5. When the water in the heating cavity is heated to steam, it will enter the air storage disk 5 through the vent 501. Under the action of the delivery mechanism, the air pressure in the first piston cylinder 6 is reduced to The steam in the gas storage disk 5 is sucked into the first piston cylinder 6 through the first absorption tube 7. When the air pressure in the first piston cylinder 6 increases, the steam in the first piston cylinder 6 will be transported to the first discharge disk 9 through the first delivery tube 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 due to 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.

[0054] See also Figures 1-4 、 Figure 6 、 Figure 7The conveying mechanism includes a motor 3 arranged 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 provided at the end of the transmission rod 4, and a first arc groove 1201 is opened at the end of the first support ring 12, and a driven assembly is provided on the first piston cylinder 6, wherein the driven assembly includes a first guide column 11 arranged in the first piston cylinder 6, a first piston disc 13 is slidably mounted on the first guide column 11, a first support wheel 14 is provided on the first piston disc 13, and the first support wheel 14 is in contact with the first arc groove 1201, and the driven assembly also includes a first fixing ring 1101 arranged on the first guide column 11, and a first spring 15 is sleeved on the first guide column 11, and the two ends of the first spring 15 are respectively in contact with the first piston disc 13 and the first fixing ring 1101.

[0055] The pressurized turbulence mechanism includes a second support ring 16 arranged on the transmission rod 4, and a second arc groove 1601 is opened on the second support ring 16. A second piston disc 17 is slidably mounted on the first guide column 11, and a second support wheel 18 is provided on the second piston disc 17 to cooperate with the second arc groove 1601. A second spring 19 is sleeved on the first guide column 11, and the two ends of the second spring 19 are respectively in contact with the second piston disc 17 and the first fixing ring 1101.

[0056] It should be noted that there are multiple first arc grooves 1201 distributed equidistantly around the circumference and have the same specifications. There are also multiple second arc grooves 1601 distributed equidistantly around the circumference and the same number as the first arc grooves 1201. The second arc grooves 1601 have different sizes. One of the second arc grooves 1601 with the smallest size is used as the starting point, and the other second arc groove 1601 at the symmetrical position is used as the end point. The second arc groove 1601 at the end point has the largest size, 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.

[0057] 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, so that the first spring 15 and the second spring 19 are both in a compressed state. When the puncture needle needs to be sterilized, the motor 3 works 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 is constantly changing, and the second arc groove The position of 1601 relative to the second support wheel 18 also continuously changes. Under the action of the first spring 15 and the second spring 19, the first support wheel 14 always adheres to the first arc groove 1201. The second support wheel 18 also remains in contact with the second arc groove 1601. As a result, the first piston disc 13 and the second piston disc 17 move away from each other and along the length of the first guide column 11, reducing the pressure in the first piston cylinder 6. Under the action of this pressure, the steam in the gas storage disc 5 is sucked into the first piston cylinder 6 through the first absorption pipe 7.

[0058] When the first support wheel 14 moves to the most recessed position of the first circular arc groove 1201, the second support wheel 18 also moves to the most recessed position of one of the second circular arc grooves 1601. At this time, the first support ring 12 and the second support ring 16 continue to rotate, and through the first circular arc groove 1201 and the first support wheel 14, as well as the second circular arc groove 1601 and the second support wheel 18, the first piston disc 13 and the second piston disc 17 are controlled to move toward each other, thereby increasing the pressure in the first piston cylinder 6 to transport the steam through the first delivery pipe 8 to the first discharge disc 9.

[0059] Preferably, when the recessed position of the next second circular arc groove 1601 moves to the mating position with the second support wheel 18, due to the difference in the recessed amount of different second circular arc grooves 1601, the size of the negative pressure suction cavity formed by the first piston cylinder 6 each time is different. 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 each time approaching or moving away from each other remains consistent. In this case, the same pumping time is accompanied by different pumping volumes, which will change the pressure of the steam sprayed by the first nozzle 10. Specifically, the steam pressure changes each time it enters the puncture needle, causing the steam to flow in a turbulent form inside the puncture needle rather than a laminar flow. This turbulent state significantly increases the chance of steam contacting the inner wall of the puncture needle, thereby greatly improving the sterilization effect of the puncture needle and ensuring the thoroughness and effectiveness of the sterilization process.

[0060] See also Figure 2 、 Figure 3 、 Figure 8、 Figure 10 The top spraying assembly includes a second piston cylinder 20 arranged on the sealing cover 2, a second discharge disk 21 is provided 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 the second absorption pipe 22 connected to the gas storage disk 5, and the second piston cylinder 20 is connected to the second delivery pipe 23 connected to the second discharge disk 21.

[0061] 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 mating 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.

[0062] See also Figures 8-10 The opposing pressure mechanism includes a second guide column 26 arranged on the second piston cylinder 20, a second fixing ring 2601 is provided 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, and the two ends of the third spring 29 are respectively in contact with the third piston disc 27 and the second fixing ring 2601, and a guide assembly is provided on the second guide column 26, wherein the guide assembly includes a third support ring 25 arranged on the transmission rod 4, a third circular arc groove 2501 is opened on the third support ring 25, and a third support wheel 28 is provided on the third piston disc 27 to abut against the third circular arc groove 2501.

[0063] Furthermore, the reflux guide head 2402 is arranged in an arc spherical shape, and the inclination angle of the open end of the reflux guide head 2402 is toward the second nozzle 24. The size and number of the third arc groove 2501 are the same as those of the first arc groove 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 disc 27 is located at the end of the stroke toward the second discharge disc 21, so that the third spring 29 is in a compressed state. When the transmission rod 4 rotates, the third support ring 25 is driven to rotate, so that the abutment position of the third arc groove 2501 and the third support wheel 28 is continuously changed. Under the action of the third spring 29, the third piston disc 27 is pressed against the third arc groove 2501. The third support wheel 28 is controlled to always be in contact with the third arc groove 2501, and the third piston disc 27 will move along the length direction of the second guide column 26 to reduce the air pressure in the second piston cylinder 20, thereby sucking the steam in the gas storage disc 5 into the second piston cylinder 20 through the second absorption pipe 22. When the third support wheel 28 is located at the most recessed position of the third arc groove 2501, the displacement of the third piston disc 27 reaches the maximum. At this time, the third support ring 25 continues to rotate, so that the third piston disc 27 moves toward the initial position to transport the steam in the second piston cylinder 20 to the second discharge disc 21 through the second delivery pipe 23, and the steam will be sprayed into the puncture needle through the second nozzle 24.

[0064] Preferably, steam can be supplied to both ends of the puncture needle simultaneously through the bidirectional pumping operation of the first nozzle 10 and the second nozzle 24. The two streams of steam entering from both ends of the puncture needle will collide with each other and move irregularly inside the puncture needle, thereby significantly increasing the residence time and effective area of ​​the steam inside the puncture needle, allowing the steam to fully contact the inner wall of the puncture needle and improving the sterilization effect.

[0065] At the same time, the air pressure of the steam sprayed by the first nozzle 10 is in dynamic change and is always higher than the air pressure of the steam sprayed by the second nozzle 24. Therefore, the force of the two steam streams impacting each other will also change continuously, further causing the steam to produce a more turbulent flow state inside the puncture needle. Eventually, the steam will be discharged from the puncture needle toward one end of the second nozzle 24, and the discharged steam will impact 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 discharged through the reflux guide head 2402. The discharged steam will impact the outside of the puncture needle, performing steam sterilization treatment on the outside of the puncture needle. By controlling the steam reflux in this way, it is possible to achieve simultaneous steam sterilization of the inside and outside of the puncture needle, ensuring the overall sterilization effect of the puncture needle.

[0066] A high-pressure steam sterilization method for a deep abscess puncture needle comprises the following steps:

[0067] Step 1: Place multiple puncture needles to be sterilized on the support frame 30;

[0068] Step 2: The conveying mechanism works and conveys the steam in the gas storage disk 5 to the first nozzle 10 through the first piston cylinder 6 and the bottom spray assembly to spray the steam to one end of the puncture needle;

[0069] Step 3: The conveying mechanism also drives the pressurizing turbulence mechanism to move and adjusts the pressure in the first piston cylinder 6 to continuously adjust the steam injection pressure;

[0070] Step 4: The conveying mechanism will also drive the opposite pressure mechanism to move, and convey the steam to the second nozzle 24 through the top spraying component to spray the steam to the other end of the puncture needle.
