Description

Technical Field

[0001] This application relates to the field of irrigation device venting technology, and in particular to an automatic irrigation device venting. Background Technology

[0002] In the medical field, especially in blood purification treatments, perfusion devices play a crucial role. They effectively adsorb toxins, metabolic waste, and other harmful substances from the blood, ensuring treatment efficacy. However, traditional perfusion devices require purging before use to ensure no air remains inside, preventing air from entering the circulatory system and causing serious adverse reactions.

[0003] The venting of the perfusion device is primarily done manually by medical staff. They typically hold the device and repeatedly tap and shake it to expel internal gases. This manual method has several drawbacks. Firstly, it is extremely inefficient, especially in hospital hemodialysis departments where a large number of perfusion devices require pretreatment. Medical staff must spend a significant amount of time and energy on the venting process, undoubtedly increasing their workload and potentially affecting the overall treatment schedule. Therefore, this patent requires an upgrade and modification based on existing technology. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides an automatic venting device for an irrigation device, which overcomes the shortcomings of the prior art and aims to solve the problem that medical staff need to spend a lot of time and energy on the venting step, which undoubtedly increases their workload and may also affect the overall treatment process.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic venting device for an irrigation device, comprising a slide rod, a rotating platform rotatably connected to the top of the slide rod, a rotating groove inside the rotating platform, a fixed rotating shaft fixedly connected inside the rotating groove, a striking arm rotatably connected to the outside of the fixed rotating shaft, a striking hammer fixedly connected to the outside of the striking arm, a connecting block slidably connected to the outside of the slide rod, a rotating mechanism rotatably connected to the outside of the connecting block, a connecting block fixedly connected to the outside of the rotating mechanism, clamping arms slidably connected to both sides of the connecting block, clamping blocks slidably connected to the outside of the clamping arms, a sliding groove inside the clamping block, a clamping arm slidably connected inside the sliding groove, a connecting rotating shaft rotatably connected to the top of the clamping arm, and a stop block at the bottom of the sliding groove.

[0006] By adopting the above technical solution, in the initial state, when the clamping block slides to the top of the clamping arm, the stop block abuts against the bottom of the connecting shaft. At this time, the clamping block rotates outward around the clamping arm, with the bottom edge of the clamping block flipping to the top position of the clamping arm. In use, the infuser is pushed into the clamping arm along the bottom plate of the clamping block. At this time, the clamping block will flip inward around the connecting shaft, so that the slide and the clamping arm are on the same horizontal plane. Then, the infuser is pushed to continue moving inward. The infuser will drive the clamping block to move to one side of the clamping arm, thereby fixing the infuser. Then, the connecting block is slid upward to move it upward along the slide rod until the infuser moves to the outside of the rotating table. By rotating the rotating table, the striking arm connected inside the rotating table will rotate outward. During the rotation of the striking arm around the rotating table, it will drive the outer striking hammer to strike the infuser, thereby realizing the discharge of gas inside the infuser.

[0007] As a preferred technical solution of this application, a motor is fixedly connected to the top position of the slide bar, and the drive end of the motor is fixedly connected to the bottom of the rotary table.

[0008] By adopting the above technical solution, the rotating table is controlled by a motor to rotate, thereby realizing the striking of the irrigation device by the striking hammer. The striking frequency of the irrigation device by the striking hammer is controlled by adjusting the speed of the motor, thereby realizing the rapid discharge of air inside the irrigation device.

[0009] As a preferred technical solution of this application, the outer side of the connecting block is threaded with a fastening bolt, and the end of the fastening bolt abuts against the outer side of the slide rod.

[0010] By adopting the above technical solution, when adjusting the position of the irrigation device, the fastening bolt is rotated so that the end of the fastening bolt no longer abuts against the outside of the slide rod. At this time, the connecting block can slide on the outside of the slide rod. When the connecting block slides to the designated position, the fastening bolt is rotated in the opposite direction so that the end of the fastening bolt abuts against the outside of the slide rod, thereby fixing the position of the connecting block.

[0011] As a preferred technical solution of this application, the rotating mechanism includes a fixed disk, a rotating shaft rotatably connected to the middle position of the fixed disk, a rotating gear fixedly connected to the outer side of the rotating shaft, a connecting rod fixedly connected to the outer side of the fixed disk, a limit block rotatably connected to the outer side of the connecting rod, and the end of the limit block abutting against the outer side of the rotating gear.

[0012] By adopting the above technical solution, the unidirectional rotation of the rotating mechanism is achieved. The rotating mechanism is set to rotate in the opposite direction to the rotation of the rotating table. When the hammer strikes the perfusion device, the hammer will not drive the rotating table to rotate during the striking process. When it is necessary to flip the perfusion device to return blood, simply rotate the connecting block 180 degrees in the opposite direction of the rotating table.

[0013] As a preferred technical solution of this application, the connecting block is provided with a connecting groove inside, a fixing spring is fixedly connected to the inner side of the connecting groove, a sliding rod is fixedly connected to the outer side of the fixing spring, and the sliding rod is fixedly connected to the inner side of the clamping arm.

[0014] By adopting the above technical solution, the sliding connection of the clamping arm on the outside of the connecting block is realized by the sliding rod setting, and the connection groove setting ensures that the clamping arm is always retracted to the outside position of the connecting block, thereby ensuring that the clamping arm can stably clamp the irrigation device.

[0015] As a preferred technical solution of this application, the end of the clamping block is fixedly connected to a covering layer, and the covering layer is made entirely of rubber.

[0016] By adopting the above technical solution, after the irrigation device is pushed into the clamping block, the covering layer can cover the inner part of the irrigation device, thereby fixing the irrigation device.

[0017] The beneficial effects of this application are:

[0018] 1. In this utility model, the rotating table drives the striking arm and striking hammer to rotate, striking the irrigation device to expel the gas inside the irrigation device. This eliminates the need for manual tapping, improving the exhaust efficiency and saving manpower and time. The motor at the top of the slide rod can control the rotation of the rotating table. By adjusting the motor speed, the striking frequency of the striking hammer on the irrigation device can be controlled, thereby enabling the rapid exhaust of air inside the irrigation device according to actual needs and further improving the exhaust effect.

[0019] 2. In this utility model, the clamping block is slidably connected to the internal sliding groove and the clamping arm. The position and state of the clamping block will change accordingly in the initial state and during the process of pushing the irrigation device in, so as to achieve stable fixation of the irrigation device and prevent the irrigation device from shaking or falling off during the venting process. The connecting block is provided with a connecting groove, a fixing spring and a sliding rod, so that the clamping arm can slide stably and retract on the outside of the connecting block, ensuring that the clamping arm has a continuous and stable clamping effect on the irrigation device. At the same time, the rubber covering layer at the end of the clamping block can cover the inner side of the irrigation device, increasing friction and fixation, and further ensuring the stability of the irrigation device during the venting process.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-7An automatic venting device for an irrigation device includes a slide rod 1, a rotating platform 8 rotatably connected to the top of the slide rod 1, a rotating groove 9 inside the rotating platform 8, a fixed rotating shaft 10 fixedly connected inside the rotating groove 9, a striking arm 11 rotatably connected to the outside of the fixed rotating shaft 10, a striking hammer 12 fixedly connected to the outside of the striking arm 11, a connecting block 2 slidably connected to the outside of the slide rod 1, a rotating mechanism 16 rotatably connected to the outside of the connecting block 2, a connecting block 3 fixedly connected to the outside of the rotating mechanism 16, clamping arms 4 slidably connected to both sides of the connecting block 3, and clamping blocks 5 slidably connected to the outside of the clamping arms 4. The clamping blocks 5 have an inverted L-shaped structure and a sliding groove 6 inside the clamping blocks 5. The clamping arms 4 are slidably connected inside the sliding groove 6. A connecting shaft 17 rotatably connects to the top of the clamping arms 4, and a stop is provided at the bottom of the sliding groove 6. In the initial state, when the clamping blocks 5 slide to the top of the clamping arms 4, the stop blocks... The clamping block 5 is abutted against the bottom of the connecting shaft 17. At this time, the clamping block 5 rotates outward around the clamping arm 4, with the bottom edge of the clamping block 5 flipping to the top position of the clamping arm 4. When in use, the irrigation device is pushed into the clamping arm 4 along the bottom plate of the clamping block 5. At this time, the clamping block 5 will flip inward around the connecting shaft 17, so that the slide 6 and the clamping arm 4 are in the same horizontal plane. Then, the irrigation device is pushed to continue to move inward. The irrigation device will drive the clamping block 5 to move to one side of the clamping arm 4, thereby fixing the irrigation device. Then, the connecting block 2 is slid upward to move it upward along the slide rod 1 until the irrigation device moves to the outside of the rotating table 8. By rotating the rotating table 8, the striking arm 11 connected inside the rotating table 8 will rotate outward. During the rotation of the striking arm 11 around the rotating table 8, it will drive the outer striking hammer 12 to strike the irrigation device, thereby realizing the discharge of gas inside the irrigation device.

[0030] In this embodiment, as Figure 1 - Figure 7 As shown, a motor is fixedly connected to the top of the slide bar 1, and the motor drive end is fixedly connected to the bottom of the rotating table 8. The rotating table 8 is rotated by the motor, thereby realizing the striking hammer 12 striking the irrigation device. The striking frequency of the striking hammer 12 on the irrigation device is controlled by adjusting the speed of the motor, thereby realizing the rapid discharge of air inside the irrigation device.

[0031] In this embodiment, as Figure 1 - Figure 7 As shown, a fastening bolt 18 is threadedly connected to the outer side of the connecting block 2. The end of the fastening bolt 18 abuts against the outer side of the slide rod 1. When adjusting the position of the irrigation device, the fastening bolt 18 is rotated so that the end of the fastening bolt 18 no longer abuts against the outer side of the slide rod 1. At this time, the connecting block 2 can slide on the outer side of the slide rod 1. When the connecting block 2 slides to the designated position, the fastening bolt 18 is rotated in the opposite direction so that the end of the fastening bolt 18 abuts against the outer side of the slide rod 1, thereby fixing the position of the connecting block 2.

[0032] In this embodiment, as Figure 1 - Figure 7 As shown, the rotating mechanism 16 includes a fixed disk 19, a rotating shaft 20 rotatably connected to the middle position of the fixed disk 19, a rotating gear 21 fixedly connected to the outer side of the rotating shaft 20, a connecting rod 22 fixedly connected to the outer side of the fixed disk 19, and a limit block 23 rotatably connected to the outer side of the connecting rod 22. The end of the limit block 23 abuts against the outer side of the rotating gear 21, thus realizing the unidirectional rotation of the rotating mechanism 16. The rotating mechanism 16 is set to rotate in the opposite direction to the rotation direction of the rotating table 8. When the hammer 12 rotates and strikes the perfusion device, the hammer 12 will not drive the rotating table 8 to rotate during the striking process. When it is necessary to flip the perfusion device to return blood, it is only necessary to rotate the connecting block 3 180 degrees in the opposite direction of the rotating table 8.

[0033] In this embodiment, as Figure 1 - Figure 7 As shown, the connecting block 3 has a connecting groove 13 inside, a fixing spring 15 is fixedly connected to the inside of the connecting groove 13, and a sliding rod 14 is fixedly connected to the outside of the fixing spring 15. The sliding rod 14 is fixedly connected to the inside of the clamping arm 4. The sliding rod 14 enables the clamping arm 4 to slide on the outside of the connecting block 3. The connecting groove 13 ensures that the clamping arm 4 is always retracted to the outside of the connecting block 3, thereby ensuring that the clamping arm 4 can stably clamp the irrigation device.

[0034] In this embodiment, as Figure 1 - Figure 7 As shown, a covering layer 7 is fixedly connected to the end of the clamping block 5. The covering layer 7 is made of rubber. After the irrigation device is pushed into the clamping block 5, the covering layer 7 can cover the inner side of the irrigation device, thereby fixing the irrigation device.

[0035] Working principle: After ensuring all components are in their initial state, the clamping block 5 slides to the top of the clamping arm 4, with the stop block abutting against the bottom of the connecting shaft 17. The clamping block 5 rotates outward around the clamping arm 4, its bottom edge flipping to the top position of the clamping arm 4. The irrigation device is then slowly pushed into the clamping arm 4 along the bottom plate of the clamping block 5. During this process, the clamping block 5 flips inward around the connecting shaft 17, gradually bringing the sliding groove 6 inside the clamping block 5 and the clamping arm 4 into the same horizontal plane. This continues to push the irrigation device inward, causing it to... The clamping block 5 moves inward along the clamping arm 4. Simultaneously, due to the internal connecting groove 13, fixing spring 15, and sliding rod 14 of the connecting block 3, the clamping arm 4 can stably slide and retract on the outside of the connecting block 3, ensuring a stable clamping effect on the irrigation device. Furthermore, the rubber coating 7 at the end of the clamping block 5 covers the inner side of the irrigation device, further enhancing its fixation. This completes the installation and fixation of the irrigation device on the device. If adjustments to the height or position of the irrigation device are needed, first rotate... The fastening bolt 18, threaded on the outside of the connecting block 2, is tightened so that the end of the fastening bolt 18 no longer abuts against the outside of the slide rod 1. At this time, the connecting block 2 can slide smoothly on the outside of the slide rod 1. After the connecting block 2 slides to the designated position, the fastening bolt 18 is rotated in the opposite direction so that the end of the fastening bolt 18 abuts against the outside of the slide rod 1 again, thereby fixing the position of the connecting block 2 and ensuring that the irrigation device is in a stable state during the following operation. The motor fixedly connected to the top of the slide rod 1 is started, and the motor drive end drives the rotating table 8 to start rotating. Because the rotating table 8 has internal... The fixed rotating shaft 10 in the rotating groove 9 is rotatably connected to the striking arm 11. The rotation of the rotating table 8 will drive the striking arm 11 to rotate outward. During the rotation of the striking arm 11 around the rotating table 8, the striking hammer 12 fixedly connected to its outer side will move accordingly, continuously striking the irrigation device located outside the rotating table 8. According to the actual situation, the striking frequency of the striking hammer 12 on the irrigation device can be controlled by adjusting the speed of the motor, so that the gas inside the irrigation device can be quickly discharged under the action of striking vibration, realizing the automatic air exhaust function of the irrigation device.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
