Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an anesthesia respirator. Background Art

[0002] An anesthesia ventilator is a device used to maintain and support a patient's breathing during surgery or other medical procedures. It is typically used during general anesthesia to ensure that the patient can get enough oxygen during anesthesia while removing carbon dioxide from the body.

[0003] The anesthesia respirator combines the delivery of anesthetic gas and respiratory support functions. Its basic components include a gas supply system, a breathing circuit, a gas mixing and regulation system, and a monitoring device. During surgery, the anesthesia respirator can accurately adjust and control the concentration of anesthetic gas and oxygen, thereby maintaining the patient's physiological stability under anesthesia, which is crucial to the success of the operation and also helps to reduce the risk of postoperative complications. Modern anesthesia respirators are usually equipped with advanced monitoring systems that can monitor the patient's respiratory rate, gas exchange and other key parameters in real time to ensure safe and effective anesthesia management. With the development of technology, anesthesia respirators are also constantly improving. New equipment is not only more stable and precise in performance, but also incorporates more intelligent functions, such as automated gas regulation and advanced alarm systems, which further improves surgical safety and patient comfort.

[0004] Anesthesia respirators are highly complex medical devices. Any technical failure or improper setting may lead to insufficient respiratory support or improper oxygen supply to the patient, which may pose a serious threat to the patient's safety. The patient is completely dependent on the ventilator to maintain breathing during anesthesia. Anesthesia respirators on the market are generally equipped with an exhaust gas treatment box filled with soda lime particles, which can react chemically with carbon dioxide to absorb the carbon dioxide produced in the patient's body and the water vapor mixed therein, thereby reducing pollution to the environment.

[0005] At present, the existing anesthesia respirators usually use masks and trachea to pass the carbon dioxide produced in the patient's body into soda lime for absorption and treatment, and it is often necessary to record on a form to show the usage time of the soda lime. However, it is necessary to manually record every half an hour, and the operation is complicated, which easily affects the convenience of use; therefore, it does not meet the existing needs.

[0019] The present invention has the following beneficial effects:

[0020] 1. When the anesthesia respirator is in use, the airbag first extends upward, driving the first piston to move upward, squeezing the hydraulic oil, and the second piston drives the rack to move downward through the transmission of the hydraulic oil. The rack meshes with the first gear, so that the first gear drives the first rotating shaft and the teeth thereon to rotate, and then the teeth mesh with the second gear, so that the second gear drives the lever to rotate a certain angle;

[0021] Subsequently, the airbag descends and recovers, and the relative rotation of the inner and outer rings of the one-way bearing keeps the first rotating shaft and the teeth stationary, thereby keeping the lever stationary. The above-mentioned action is repeated, and the airbag is lifted and lowered back and forth for half an hour, driving the lever to rotate one circle, thereby moving the first blade, thereby indicating that the usage time of the soda lime is half an hour. At the same time, the second blade rotates to the position of the original first blade, and so on. It is convenient to judge the usage time of the soda lime in the processing box by moving the blades, thereby improving the convenience of using the device.

[0022] 2. In the anesthesia respirator, when the lever moves the last blade, the blade drives the housing and the first terminal to move, so that the first terminal contacts the second terminal, and the first spring is compressed, thereby forming a complete circuit loop between the telescopic member and the external power supply, so that the telescopic member pulls the first baffle away from the first material hole, so that the used soda lime in the processing box falls into the waste box through the first material hole;

[0023] Moreover, after all the soda lime in the processing box falls into the waste box, the telescopic part drives the first baffle to reset and close the first material hole. Under the action of the overall gravity of the waste box, the waste box drives the first wedge block to move down over the second wedge block and press the pressure plate downward, so that the pressure plate drives the third wedge block to move down through the straight rod. Through the coordinated use of the third wedge block and the fourth wedge block, the fourth wedge block drives the second baffle away from the second material hole through the connecting rod, so that the soda lime in the storage box falls into the processing box, which is convenient for timely replacement of the soda lime waste that has reacted completely in the processing box, thereby further improving the convenience of using the device. Finally, the waste box is manually pushed up to reset it, so that the second baffle is reset to close the second material hole again, which is convenient for the reuse of the equipment.

[0024] 3. In the anesthesia respirator, when the waste box moves downward, the first wedge block and the second wedge block are used in coordination, so that the second wedge block drives the extrusion block to slide and extrude on the deceleration hose, so that the air in the deceleration hose at the squeezed position flows to both sides through the air holes. Since the aperture of the air holes is small, air circulation is difficult, which makes the extrusion block move slowly on the deceleration hose, thereby extending the time for the first wedge block to pass over the second wedge block, and reserving sufficient time for the first baffle to close the first material hole. When the first wedge block passes over the second wedge block, the waste box presses the pressure plate downward to open the second material hole, thereby avoiding as much as possible that the soda lime in the storage box falls into the processing box and then slides into the waste box through the first material hole to cause waste.

DETAILED DESCRIPTION

[0036] 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.

[0037] Embodiment 1: This embodiment aims to solve the problem that the existing anesthesia respirator usually uses a mask and a trachea to pass the carbon dioxide produced in the patient's body into the soda lime for absorption and treatment, and often needs to be recorded on a table to show the use time of the soda lime. However, it needs to be recorded manually every half an hour, which is complicated to operate and easily affects the convenience of use. Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7An anesthesia respirator includes a respirator body 100, a treatment box 101 fixedly mounted on the outside of the respirator body 100, soda lime 102 arranged in the treatment box 101, a bellows 110 fixedly mounted on the outside of the respirator body 100, and an air bag 120 arranged in the bellows 110. When the respirator body 100 is in use, the air bag 120 will reciprocate up and down, and the carbon dioxide generated in the patient's body will pass into the treatment box 101 through a pipeline, so that the carbon dioxide reacts with the soda lime in the treatment box 101. The above are all technical means well known to technicians in this field and will not be described in detail here.

[0038] A rack 130 is slidably provided on the side of the ventilator body 100, and a connecting pipe 131 is fixedly inserted on the top of the bellows 110. The connecting pipe 131 is configured as a "U"-shaped tube opening downward. A first piston 132 is slidably inserted at one end of the connecting pipe 131 located inside the bellows 110, and the lower end of the first piston 132 is fixedly connected to the top of the airbag 120. A second piston 133 is slidably inserted at one end of the connecting pipe 131 located outside the bellows 110, and the lower end of the second piston 133 is fixedly connected to the top of the rack 130. Hydraulic oil 134 is filled between the first piston 132, the second piston 133, and the connecting pipe 131.

[0039] A first rotating shaft 140 is rotatably installed on the outside of the ventilator body 100, and a first gear 150 is rotatably arranged on the outside of the first rotating shaft 140. A one-way bearing 151 is provided with an interference sleeve on the outside of the first rotating shaft 140, and the first gear 150 is fixedly sleeved on the outside of the one-way bearing 151. The first rotating shaft 140 is fixedly fitted with the inner ring of the one-way bearing 151, and the first gear 150 is fixedly fitted with the outer ring of the one-way bearing 151. A ratchet structure is arranged inside the one-way bearing 151. When the outer ring of the one-way bearing 151 rotates in the positive direction, the inner ring of the one-way bearing 151 rotates synchronously with the outer ring. When the outer ring of the one-way bearing 151 rotates in the reverse direction, the inner ring of the one-way bearing 151 remains stationary. This is a technical means well known to technicians in this field and will not be elaborated here.

[0040] A tooth 160 is fixedly installed at the end of the first rotating shaft 140, a second gear 170 is rotatably installed on the outer side of the ventilator body 100, the second gear 170 is meshed with the tooth 160, a lever 180 is fixedly installed on the outer side of the second gear 170, an impeller 190 is rotatably arranged on the outer side of the ventilator body 100, the impeller 190 is used to record the usage time of the soda lime 102, a second rotating shaft 191 is rotatably installed on the side of the ventilator body 100, the impeller 190 is fixedly sleeved on the end of the second rotating shaft 191, a blade 200 is fixedly installed on the outer side of the impeller 190, the lever 180 is used to move the blade 200, the number of the blades 200 is set to be several, and the several blades 200 are evenly installed on the outer side of the impeller 190 in an annular direction.

[0041] The outer side of the impeller 190 is evenly circumferentially provided with scale lines, and the values ​​of the scale lines correspond to the number and position of the blades 200 one by one, so that the lever 180 moves the blade 200 once every half an hour, thereby displaying the usage time of the soda lime 102 through the scale line values ​​corresponding to the blades.

[0042] In this embodiment: when the ventilator body 100 is in use, the airbag 120 first extends upward, driving the first piston 132 to move upward, squeezing the hydraulic oil 134, and the second piston 133 drives the rack 130 to move downward through the transmission of the hydraulic oil 134, and the first gear 150 is meshed with the rack 130, so that the first gear 150 drives the first rotating shaft 140 and the teeth 160 thereon to rotate, and then the teeth 160 are meshed with the second gear 170, so that the second gear 170 drives the lever 180 to rotate a certain angle;

[0043] Subsequently, the airbag 120 is lowered and restored, and the first rotating shaft 140 and the tooth 160 remain stationary through the relative rotation of the inner and outer rings of the one-way bearing 151, so that the lever 180 remains stationary. The above-mentioned action is repeated, and the airbag 120 is reciprocated and lifted for half an hour, driving the lever 180 to rotate one circle, so that the first blade 200 is moved, thereby indicating that the usage time of the soda lime 102 is half an hour. At the same time, the second blade 200 rotates to the position of the original first blade, and so on, so as to judge the soda lime 102 in the processing box 101 by the moved blade 200. 2, thereby improving the convenience of using the device. When the lever 180 moves the last blade 200, it indicates that the soda lime 102 in the processing box 101 has completely reacted with the carbon dioxide, and the soda lime 102 therein needs to be replaced. This solves the problem that the existing anesthesia respirator usually uses a mask and a trachea to pass the carbon dioxide generated in the patient's body into the soda lime for absorption and treatment, and it is often necessary to record on a table to show the usage time of the soda lime. However, it needs to be recorded manually every half an hour, which is complicated to operate and easily affects the convenience of use.

[0044] Embodiment 2: This embodiment is intended to further promote the solution of the problem that it is inconvenient to replace the completely reacted soda lime waste in the processing box 101 in time, thereby affecting the convenience of using the device.

A pressing plate 255 is fixedly installed at the lower end of the straight rod 250, and the pressing plate 255 is set below the waste box 212.

[0050] In this embodiment: when the lever 180 moves the last blade 200, the blade 200 drives the housing 220 and the first terminal 221 to move, so that the first terminal 221 contacts the second terminal 226, and the first spring 222 is compressed, so that the telescopic member 224 and the external power supply form a complete circuit loop, so that the telescopic member 224 pulls the first baffle 231 away from the first material hole 230, so that the used soda lime 102 in the processing box 101 falls into the waste box 212 through the first material hole 230;

[0051] Moreover, after all the soda lime 102 in the processing box 101 falls into the waste box 212, the telescopic member 224 drives the first baffle 231 to reset, closing the first material hole 230. Under the action of the overall gravity of the waste box 212, the waste box 212 drives the first wedge block 240 to move downward over the second wedge block 241 and press the pressing plate 255 downward, so that the pressing plate 255 drives the third wedge block 251 to move downward through the straight rod 250. Through the cooperation of the third wedge block 251 and the fourth wedge block 252, the first wedge block 240 is moved downward. In use, the fourth wedge block 252 drives the second baffle 233 away from the second material hole 232 through the connecting rod 254, so that the soda lime 102 in the storage box 210 falls into the processing box 101, which is convenient for timely replacement of the soda lime waste that has reacted completely in the processing box 101, thereby further improving the convenience of using the device. Finally, the waste box 212 is manually pushed up to reset it, so that the second baffle 233 is reset to close the second material hole 232 again, which is convenient for the reuse of the equipment.

[0052] Embodiment 3: This embodiment is intended to solve the problem that if the waste box 212 presses the pressure plate 255 downward too quickly, the second material hole 232 is opened before the first baffle 231 is reset in time to close the first material hole 230, which easily causes the loss and waste of soda lime 102.

A spacer 261 is arranged inside the deceleration hose 260, and the side of the spacer 261 is fixedly connected to the inner wall of the deceleration hose 260. The number of the spacers 261 is set to be several, and the several spacers 261 are evenly arranged in the deceleration hose 260 in the transverse direction, and the middle of the spacers 261 is opened with air holes 262, and an extrusion block 263 is fixedly installed on the outer side of the second wedge block 241, and the extrusion block 263 squeezes the deceleration hose 260.

[0053] In this embodiment: when the waste box 212 moves downward, the first wedge block 240 and the second wedge block 241 are used in coordination, so that the second wedge block 241 drives the squeezing block 263 to slide and squeeze on the deceleration hose 260, so that the air in the deceleration hose 260 at the squeezed position flows to both sides through the air holes 262. Since the aperture of the air holes 262 is small, air circulation is difficult, so that the moving speed of the squeezing block 263 on the deceleration hose 260 is slow, thereby extending the time for the first wedge block 240 to pass over the second wedge block 241, and reserving sufficient time for the first baffle 231 to close the first material hole 230. When the first wedge block 240 passes over the second wedge block 241, the waste box 212 presses the pressing plate 255 downward to open the second material hole 232, thereby avoiding as much as possible that the soda lime 102 in the storage box 210 falls into the processing box 101 and then slides into the waste box 212 through the first material hole 230 to cause waste.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
