Description

Technical Field

[0001] The invention relates to the field of medical technology, and in particular to an anesthetic gas purification device for clinical use in anesthesiology. Background Art

[0002] The background of the clinical anesthetic gas purification device in the Department of Anesthesiology is to solve the safety problems that may exist during anesthesia. In anesthesia surgery and other anesthesia operations, anesthetic gases are often used to make patients unconscious for pain relief and surgical operations. However, there may be some harmful substances in the anesthetic gas, which poses a potential risk to the health of patients and medical staff. Harmful substances in anesthetic gases include volatile organic compounds and toxic gases, such as nitrous oxide, halothane, sevoflurane, etc. If these substances are inhaled excessively or exposed for a long time during anesthesia, they may cause damage to the human body, such as nervous system damage, liver and kidney dysfunction, etc. In order to reduce the health risks of patients and medical staff, the clinical anesthetic gas purification device in the Department of Anesthesiology came into being. The device can effectively remove particles and harmful chemicals in anesthetic gases, capture tiny particles to prevent them from entering the patient's respiratory system, adsorb harmful substances, and ensure the purity of anesthetic gases.

[0003] After searching, the invention patent with Chinese patent number CN114768461A discloses an anesthetic gas purification device for clinical use in anesthesia department, which relates to the field of medical technology, and solves the problem that some current anesthetic gas purification devices are composed of a body and a purification device, but some current anesthetic gas purification devices only filter the anesthetic gas through a filter net, making the filtration and purification of the anesthetic gas relatively simple, and the cleanliness of the anesthetic gas cannot be guaranteed under certain conditions, and affects the comfort of the patient when inhaling. The invention patent includes a frame, an anesthetic gas box is arranged on the top of the frame, and the top of the frame is provided with an anesthetic gas box. The sterilization box is connected to the inside of the gas box, and the sterilization box is located on the left side of the anesthesia gas box. The anesthesia gas box is connected to the inside of the sterilization box through a connecting pipe. The left side of the sterilization box is fixedly connected with a purification box connected to the inside of the sterilization box. The inner wall of the purification box is provided with two mirrored slide grooves. The clinical anesthesia gas purification device of the anesthesia department filters the gas multiple times through the activated carbon layer and the filter net, thereby achieving the filtration of the anesthetic gas, allowing the patient to inhale the anesthetic gas more comfortably, and making the filtration and purification of the anesthetic gas more thorough, thereby ensuring the cleanliness of the anesthetic gas to a certain extent, so that the patient can use the anesthetic gas more safely.

[0004] However, during actual use of the above-mentioned device, the clinical anesthetic gas purification device for anesthesiology, through the T-shaped cross-section of the slide groove and the slider, limits the moving direction of the slider, and reduces the offset and jamming of the slider during movement to a certain extent, so that the slider can move more smoothly and medical staff can more conveniently disassemble the first mounting frame and the second mounting frame. During this process, dust accumulates on the surface of the filter over time, affecting its use. The first mounting frame needs to be disassembled to clean the filter, which is inconvenient to use. Therefore, an anesthetic gas purification device for clinical anesthesia is proposed. Summary of the invention

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An anesthetic gas purification device for clinical use in anesthesiology, comprising a frame, a buffer mechanism is arranged outside the frame, the buffer mechanism comprises a first spring arranged outside the frame, a support rod is fixedly connected to a side of the first spring away from the frame, a fixed base is fixedly connected to a side of the support rod away from the first spring, an anesthetic gas box and a sterilization box are fixedly connected to the outside of the fixed base, and a purification box is arranged outside the sterilization box;

[0008] A mounting bracket is slidably connected to the interior of the purification box, a cleaning mechanism for cleaning the filter is arranged inside the purification box, the cleaning mechanism includes a support shaft arranged inside the purification box, a rotating shaft is rotatably connected to the outside of the support shaft, a fan blade and a fixed rod are fixedly connected to the outside of the rotating shaft, a fourth spring is fixedly connected to the outside of the fixed rod, an impact block is fixedly connected to the outside of the fourth spring, a torsion spring is fixedly connected to the outside of the rotating shaft, and the torsion spring is fixedly connected to the support shaft on one side away from the rotating shaft.

[0009] Wherein, an activated carbon layer is placed on the upper layer of the mounting frame (the activated carbon layer can be replaced by other purification devices), and a filter is placed on the lower layer.

[0010] The above technical solution further includes:

[0011] The frame is fixedly connected to the outside of the frame, and a supporting mechanism is arranged on the outside of the frame. The supporting mechanism includes a sliding block arranged on the outside of the frame, the sliding block is symmetrically rotatably connected to a first connecting plate on the outside, the first connecting plate is rotatably connected to a second connecting plate on the outside, the first connecting plate is rotatably connected to a supporting platform on the outside, the second connecting plate is rotatably connected to a connecting shaft on the outside, and the supporting platform and the connecting shaft are slidably connected.

[0012] The frame is slidably connected to the sliding block, the sliding block is externally threadedly connected to a threaded rod, the frame is rotatably connected to the threaded rod, and the threaded rod is externally fixedly connected to a rotating handle.

[0013] The frame is fixedly connected with a fixed shaft on the outside, the fixed shaft is symmetrically slidably connected with a sliding ring on the outside, the sliding ring is rotatably connected with a connecting rod on the outside, and the support rod is rotatably connected to the connecting rod.

[0014] A second spring is fixedly connected to the outside of the sliding ring, a side of the second spring away from the sliding ring is fixedly connected to the vehicle frame, and the fixed shaft is slidably connected to the support rod.

[0015] The purification box is symmetrically provided with card slots on the outside, a card block is slidably connected to the outside of the card slot, a cover plate is slidably connected to the outside of the card block, and the cover plate is slidably connected to the purification box.

[0016] A control groove is provided on the outside of the cover plate, the clamping block is slidably connected to the control groove, a third spring is fixedly connected to the outside of the clamping block, and a side of the third spring away from the clamping block is fixedly connected to the cover plate.

[0017] A dust collecting plate is arranged inside the purification box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, when in use, when the anesthetic gas enters the purification box and is inhaled by the patient, the airflow control generated by the anesthetic gas drives the fan blades to rotate, and then drives the rotating shaft to rotate, and causes the torsion spring to change from a relaxed state to a tight state.

When the torsion spring is in a fully tense state, the force of the airflow controlling the rotation of the fan blades and the force generated by the torsion spring will be in dynamic balance, that is, the rotating shaft rotates back and forth, thereby controlling the impact block to reciprocately collide with the filter to separate the dust and impurities on the filter.

[0020] 2. In the present invention, when in use, after the inhalation of anesthetic gas ends, the anesthetic gas no longer generates airflow, and at this time the torsion spring controls the rotation shaft to rotate, and the rotation of the rotation shaft drives the fixed rod, the fourth spring and the impact block to rotate so that the impact block continuously collides with the filter placed on the mounting frame, thereby separating the dust and impurities on the filter from the filter and dropping them into the dust collection plate placed inside the purification box, thereby reducing the number of times the filter is disassembled and cleaned and improving the comfort of use.

[0021] 3. In the present invention, when the device is in use, when the frame and the fixed base shake when the device passes through an uneven road surface, the support rod shakes up and down to squeeze the first spring, and at the same time, the support rod moves to control the sliding ring to move on the fixed axis through the connecting rod, and the sliding ring moves to squeeze or stretch the second spring. Through the dual cooperation of the first spring and the second spring, the structure of the device is protected to a certain extent, thereby improving the stability of the device.

[0022] 4. In the present invention, when in use, after the medical staff controls the device to a specified position, they rotate the threaded rod to control the movement of the sliding block and control the first connecting plate and the second connecting plate to be parallel, thereby moving the support platform downward until the support platform contacts the ground to stably support the device, allowing the support platform to move vertically and reduce the wear rate.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] like Figure 1-10 As shown, an anesthetic gas purification device for clinical use in anesthesia department comprises a frame 1, a buffer mechanism is arranged outside the frame 1, the buffer mechanism comprises a first spring 16 arranged outside the frame 1, a support rod 14 is fixedly connected to a side of the first spring 16 away from the frame 1, a fixed base 2 is fixedly connected to a side of the support rod 14 away from the first spring 16, an anesthetic gas box 3 and a sterilization box 4 are fixedly connected to the outside of the fixed base 2, and a purification box 5 is arranged outside the sterilization box 4;

[0037] A mounting frame 33 is slidably connected inside the purification box 5, an activated carbon layer is placed on the upper layer of the mounting frame 33 (the activated carbon layer can be replaced by other purification devices), and a filter is placed on the lower layer. A cleaning mechanism for cleaning the filter is arranged inside the purification box 5, and the cleaning mechanism includes a support shaft 27 arranged inside the purification box 5, and the support shaft 27 is rotatably connected to the rotating shaft 25 outside, and the rotating shaft 25 is fixedly connected to the fan blade 26 and the fixed rod 28 outside, and the fixed rod 28 is fixedly connected to the fourth spring 29 outside, and the fourth spring 29 is fixedly connected to the impact block 30 outside, and the rotating shaft 25 is fixedly connected to the torsion spring 31 outside, and the torsion spring 31 is fixedly connected to the support shaft 27 on the side away from the rotating shaft 25. A dust collection plate 32 is arranged inside the purification box 5.

[0038] The working principle of the clinical anesthetic gas purification device for anesthesia department proposed by the present invention is that when in use, the clinical anesthetic gas purification device for anesthesia department generates anesthetic gas in the anesthetic gas box 3, which is sterilized by the sterilization box 4, and the sterilized anesthetic gas enters the purification box 5 for purification, and the anesthetic gas in the purification box 5 is filtered by the activated carbon layer and the filter net arranged on the mounting frame 33, thereby filtering the anesthetic gas, so that the patient can inhale the anesthetic gas more comfortably, and the filtration and purification of the anesthetic gas is more thorough;

[0039] When the anesthetic gas enters the purification box 5 and is inhaled by the patient, Figure 5 and Fig.10 As shown, the airflow control generated by the anesthetic gas drives the fan blades 26 to rotate, and the rotation of the fan blades 26 drives the rotating shaft 25 to rotate. The rotating shaft 25 rotates on the supporting shaft 27. The rotation process of the rotating shaft 25 causes the torsion spring 31 to be relaxed and then become tense. At the same time, the rotation of the rotating shaft 25 drives the fixing rod 28, the fourth spring 29 and the impact block 30 to rotate. During the rotation process, the impact block 30 will continuously collide with the filter screen installed on the mounting frame 33, so that the dust and impurities on the filter screen are separated from the filter screen and fall into the dust collecting plate 32 placed inside the purification box 5. When the torsion spring 31 is in a completely tense state, the force of the airflow control fan blades 26 and the force generated by the torsion spring 31 will be in dynamic balance, that is, the rotating shaft 25 rotates back and forth, thereby controlling the impact block 30 to reciprocately collide with the filter screen to separate the dust and impurities on the filter screen.

[0040] After the inhalation of the anesthetic gas ends, the anesthetic gas no longer generates airflow, and the fan blades 26 no longer drive the rotating shaft 25 to rotate. At this time, the torsion spring 31 controls and drives the rotating shaft 25 to rotate. The rotation of the rotating shaft 25 drives the fixed rod 28, the fourth spring 29 and the impact block 30 to rotate. During the rotation process, the impact block 30 will continuously collide with the filter installed on the mounting frame 33, thereby separating the dust and impurities on the filter from the filter and falling into the dust collection plate 32 placed inside the purification box 5.

[0045] The working principle of the clinical anesthetic gas purification device for anesthesia department proposed by the present invention is that the medical staff puts their hands in the control slot 24 and holds the card block 21 to control it to slide toward the middle, the card block 21 slides toward the middle of the cover plate 20 and compresses the third spring 22, and at the same time the third spring 22 will be separated from the card slot 23 on the purification box 5, thereby realizing the release of the cover plate 20, so that the medical staff can more smoothly install and remove the cover plate 20;

[0046] When the device is moved by medical staff and passes over an uneven road surface, the frame 1 and the fixed base 2 shake, and the support rod 14 shakes up and down to squeeze the first spring 16. At the same time, the support rod 14 moves through the connecting rod 17 to control the sliding ring 18 to move on the fixed shaft 15. The sliding ring 18 moves to squeeze or stretch the second spring 19. The double cooperation of the first spring 16 and the second spring 19 protects the structure of the device to a certain extent.
