Description

Technical Field

[0001] The present invention relates to the field of anesthesia equipment, and in particular to an anesthesia machine with a function of preventing a mask air pipe from falling off. Background Art

[0002] In the field of anesthesia equipment, the gas tube and mask of the anesthesia machine are key components to ensure patient safety. The gas tube is used to deliver anesthetic gas to the patient's respiratory tract, while the mask is responsible for directing the gas to the patient's oral and nasal cavities. During surgery, the stability and position control of the gas tube directly affect the smooth delivery of anesthetic gas, which is crucial to maintaining the patient's anesthesia state. In addition, the connection between the gas tube and the mask must be firm and reliable to avoid interruption or uneven gas delivery, thereby ensuring patient safety.

[0003] Currently, many anesthesia machines are equipped with an adjustable clamping mechanism to fix the air tube, which is designed to improve the stability of the air tube and ensure that the connection between the mask and the air tube will not be damaged by external factors (such as collision or accidental movement). These clamping mechanisms can usually be adjusted manually or automatically to accommodate air tubes of different lengths and diameters.

[0004] Although these solutions help improve safety, there are still some problems in actual use. The air tube is usually made of soft materials and may bend or fold after long-term use. When adjusting the air tube, especially during the process of retrieving the air tube, the actual stroke of the air tube may be less than the designed stroke of the clamping mechanism due to the possible deformation of the air tube. This means that after the air tube and the mask are fully retracted into place, there may be a certain pulling state between the air tube and the mask. This continuous pulling may cause the connection between the air tube and the mask to gradually loosen or fall off, posing a hidden danger to patient safety. Summary of the invention

[0005] The purpose of the present invention is to provide an anesthesia machine with a function of preventing the mask air tube from falling off, so as to solve the problem proposed in the above background technology that after the air tube and the mask are completely retracted into place, a certain pulling state may be maintained between the air tube and the mask, thereby causing an unstable connection between the air tube and the mask.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An anesthesia machine with a function of preventing a mask and an air tube from falling off, comprising a storage bracket, a mask clamping mechanism and an air tube clamping mechanism; the mask clamping mechanism has at least two first clamping parts, at least two of the first clamping parts are selectively slidably arranged on the front side of the storage bracket, suitable for at least two of the first clamping parts to slide up and down and form an adjustable clamping area between each other, wherein a side of the adjustable clamping area close to the storage bracket forms a first fixed side, and a side of the adjustable clamping area away from the storage bracket forms a second fixed side; the air tube clamping mechanism has a second clamping part, the second clamping part is slidably arranged on the storage bracket, suitable for the second clamping part to slide left and right and form a delivery channel between the mask clamping mechanism, and the delivery channel is at least partially interspersed with the adjustable clamping area; wherein, in the state of storage completion, the first fixed side and the second fixed side of the adjustable clamping area simultaneously close the delivery channel.

[0008] Furthermore, the mask storage mechanism has a first drive component, the first drive component has an input end and an output end, the input end is arranged on the rear end of the storage bracket, the output end is transmission connected to at least two of the first clamping parts, and the second clamping part can be slidably abutted against the input end and is suitable for driving at least two of the first clamping parts to slide.

[0009] Furthermore, an installation groove is provided on the side wall of the storage bracket, and the installation groove is arranged on the front side of the input end of the first drive component. The second clamping portion is slidably clamped in the installation groove, wherein when the second clamping portion slides and stops at a side of the installation groove close to the input end of the first drive component, the second clamping portion forms a sliding abutment against the input end of the first drive component.

[0010] Furthermore, one of the structures in the first driving component is a reset member, and the reset member is arranged on the side wall of the storage rack. The reset member is elastic and can elastically abut against the input end of the first driving component, wherein when the reset member and the input end of the first driving component are released from the elastic abutment state, the elastic member is suitable for driving at least two of the first clamping parts away from each other.

[0011] Furthermore, the mask clamping mechanism has a second drive component, the second drive component has a mounting seat and a guide rail, at least two of the first clamping parts are assembled on the mounting seat, and the mounting seat is slidably set on the guide rail, suitable for when the first fixed side and the second fixed side of the adjustable clamping area simultaneously close the conveying channel, the mounting seat slides toward the second clamping part.

[0012] Furthermore, one of the output ends of the first driving component is constructed as a rocker arm, at least two of the first clamping parts are arranged vertically opposite to each other, and at least two of the first clamping parts are provided with vertical sliding grooves on the side walls, and one end of the rocker arm is slidably accommodated in the sliding groove, which is suitable for the first clamping part to slide up and down when one end of the rocker arm slides and abuts against the side wall of the sliding groove.

[0013] Furthermore, the slide groove has an avoidance section, which is located at one end of the slide groove close to the adjustable clamping area, and the avoidance section is arranged toward the second clamping portion. The rocker arm can slide against a side of the avoidance section close to the adjustable clamping area, which is suitable for keeping the conveying channel closed when the mounting seat slides toward the second clamping portion.

[0014] Furthermore, the gas pipe clamping mechanism has a rotating rod, which is mounted in the mounting groove, and the two ends of the rotating rod are respectively rotatably matched with the side walls of the mounting groove, the second clamping part is sleeved on the rotating rod, and the first clamping part is threadably matched with the rotating rod.

[0016] Furthermore, the avoidance section has an arc portion, and the center of the arc portion faces the adjustable clamping area.

[0017] The advantages of the anesthesia machine with the function of preventing the mask air pipe from falling off described in the present invention over the prior art are:

[0018] Through the delivery channel formed between the second clamping part and the mask clamping mechanism, and the design that the delivery channel is at least partially interspersed with the adjustable clamping area, the recovery length of the air pipe is made greater than the stroke of the second clamping part, ensuring that no additional tension is generated after the air pipe is fully recovered into place, thereby avoiding the problem of unstable connection between the air pipe and the mask due to excessive pulling.

[0019] Through the joint action of the first fixed side and the second fixed side of the adjustable clamping area, the air pipe is effectively divided in the stored state, ensuring that the part where the air pipe is connected to the mask becomes a whole, thereby increasing the stability of the connection between the air pipe and the mask.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example 1, reference Figure 1 The anesthesia machine with the function of preventing the mask and air tube from falling off provided in this embodiment includes a storage bracket 10, a mask clamping mechanism and an air tube clamping mechanism. The storage bracket 10 can be installed at the front end of the anesthesia machine by fasteners such as bolts, that is, the anesthesia machine has one end of the air tube (the air tube is not shown in the figure), and the storage bracket 10 serves as a supporting structure of the entire system, and is used to install and support the mask clamping mechanism and the air tube clamping machine.

[0029] The mask clamping mechanism includes at least two first clamping parts 201, which are arranged in an upper and lower facing manner. The lower first clamping part 201 is fixedly mounted on the storage bracket 10, and the upper first clamping part 201 can slide up and down along the front side of the storage bracket 10 to accommodate masks of different sizes. At least two first clamping parts 201 can form an adjustable clamping area between each other, which is used to clamp the mask. The side of the adjustable clamping area close to the storage bracket 10 forms a first fixed side, and the side away from the storage bracket 10 forms a second fixed side. The first fixed side and the second fixed side are jointly formed by the upper and lower first clamping parts 201 abutting against each other.

[0030] The air pipe clamping mechanism has a second clamping portion 301, which is slidably arranged on the storage bracket 10 and is used to clamp the air pipe. The position is adjusted by sliding left and right, thereby realizing the adjustment and recovery of the air pipe. The air pipe clamping mechanism and the mask clamping mechanism together form a delivery channel to ensure that the air pipe can be delivered smoothly, and the delivery channel is at least partially interspersed in the adjustable clamping area.

[0031] In the state where the storage is completed, the first fixed side and the second fixed side of the adjustable clamping area simultaneously close the conveying channel.

[0032] When the air pipe is recovered, the position of the second clamping part 301 is adjusted to ensure that the air pipe stably passes through the delivery channel. The design of the delivery channel ensures that the recovery length of the air pipe is greater than the stroke of the second clamping part 301, thereby avoiding the instability problem that may be caused by excessive pulling of the connection between the air pipe and the mask. When the air pipe is recovered, the first fixed side and the second fixed side work together to achieve effective segmentation of the air pipe in the stored state, ensuring that the part where the air pipe is connected to the mask becomes a whole, thereby increasing the stability of the connection.

[0033] Example 2, reference Figure 2-Figure 3 On the basis of the above embodiment, the mask storage mechanism has a first driving component 40, the first driving component 40 has an input end 401 and an output end 402, the input end 401 is arranged on the rear end of the storage bracket 10, the output end 402 is transmission-connected with at least two first clamping parts 201, and the second clamping part 301 can be slidably abutted against the input end 401 and is suitable for driving at least two first clamping parts 201 to slide.

[0034] In specific implementation, the input end 401 of the first driving assembly 40 can be designed as a rod or a push rod. When the second clamping part 301 slides to a specific position, it will apply pressure to the input end 401, causing the lever or push rod to move, thereby starting the driving assembly. The first clamping part 201 can be connected to the output end 402 through a slider, a connecting rod or other transmission components. When the output end 402 rotates, the first clamping part 201 is driven to slide up and down through these transmission components. When the second clamping part 301 slides to a specific position, it will apply pressure to the input end 401, triggering the lever or push rod to move, thereby starting the first driving assembly 40. The output end 402 transmits power to the first clamping part 201 through the transmission device, causing the first clamping part 201 to slide up and down to form an adjustable clamping area.

[0035] This design ensures the synchronization of the recovery of the air pipe and the segmentation of the air pipe. This ensures that when the air pipe is stored, the first fixed side and the second fixed side of the adjustable clamping area simultaneously close the delivery channel, thereby avoiding the problem of unstable connection between the air pipe and the mask.

[0036] Example 3, reference Figure 4 On the basis of the above embodiment, further, a mounting groove 50 is opened on the side wall of the storage bracket 10, and the mounting groove 50 is arranged on the front side of the input end 401 of the first driving component 40, and the second clamping portion 301 is slidably clamped in the mounting groove 50, wherein, when the second clamping portion 301 slides and stops at a side of the mounting groove 50 close to the input end 401 of the first driving component 40, the second clamping portion 301 forms a sliding abutment with the input end 401 of the first driving component 40.

[0037] In a specific implementation, the installation groove 50 is opened along the extension direction of the storage bracket 10 to ensure that the second clamping portion 301 can slide smoothly along the length direction of the storage bracket 10, and limiting grooves are opened at the top and bottom of the installation groove 50. The top and bottom ends of the second clamping portion 301 are provided with clamping blocks matching the limiting grooves. The second clamping portion 301 is slidingly clamped with the installation groove 50 through the clamping blocks to prevent the second clamping portion 301 from falling out of the installation groove 50.

[0038] When the second clamping portion 301 slides to the side of the mounting slot 50 close to the input end 401 of the first drive assembly 40, the second clamping portion 301 forms a sliding contact with the input end 401 of the first drive assembly 40. This means that when the second clamping portion 301 stops moving and completes the recovery of the air pipe, the adjustable clamping area simultaneously achieves the clamping of the air pipe and the mask. This design further ensures the synchronization of the air pipe segmentation and avoids the formation of tension between the air pipe and the mask during the recovery of the air pipe.

[0039] This design further ensures the synchronization of the gas pipe segmentation, and avoids the formation of tension between the gas pipe and the mask during the process of recovering the gas pipe.

[0040] Embodiment 4, on the basis of the above embodiments, a reset member 403 is constructed in the first driving component 40, and the reset member 403 is arranged on the side wall of the storage rack. The reset member 403 is elastic and can elastically abut against the input end 401 of the first driving component 40, wherein when the reset member 403 and the input end 401 of the first driving component 40 are released from the elastic abutment state, the elastic member is suitable for driving at least two first clamping parts 201 away from each other.

[0041] In a specific implementation, the reset member 403 may be a spring, a spring sheet or other elastic element, and the two ends of the reset member 403 are respectively fixedly connected to the storage bracket 10 and the input end 401 of the first drive component 40. Through the design of the reset member 403, when the second clamping portion 301 is released from the abutment with the input end 401 of the first drive component 40, the reset member 403 can drive at least two first clamping portions 201 away from each other, thereby facilitating the adjustment of the air pipe.

[0042] Example 5, reference Figure 5 On the basis of the above embodiment, the mask clamping mechanism has a second drive assembly, the second drive assembly has a mounting seat 601 and a guide rail 602, at least two first clamping parts 201 are assembled on the mounting seat 601, and the mounting seat 601 is slidably set on the guide rail 602, which is suitable for when the first fixed side and the second fixed side of the adjustable clamping area simultaneously close the conveying channel, the mounting seat 601 slides toward the second clamping part 301.

[0043] In a specific implementation, the mounting seat 601 can be a platform structure for carrying at least two first clamping parts 201. At least two first clamping parts 201 are installed on the mounting seat 601 through a sliding mechanism (such as a slide rail or a slider) to ensure that the first clamping part 201 can slide up and down on the mounting seat 601. The guide rail 602 is fixedly installed on the storage bracket 10, and can be one or more parallel guide rails 602, which are used to guide the mounting seat 601 to slide along the length direction of the storage bracket 10. The mounting seat 601 is connected to the guide rail 602 through a slider or other sliding mechanism to ensure that the mounting seat 601 can slide smoothly along the guide rail 602.

[0044] Due to the hose characteristics of the air pipe, it may undergo transitional deformation during long-term use, such as transitional folding, bending, etc., which may cause the recovery length of the air pipe to be less than the stroke of the second clamping portion 301, resulting in excessive pulling between the air pipe and the mask after the recovery is completed, causing the connection between the air pipe and the mask to loosen or even fall off. This embodiment ensures that during the recovery process of the air pipe, even if the air pipe is deformed, the sliding adjustment of the mounting seat 601 can ensure a stable connection between the air pipe and the mask, thereby avoiding connection problems caused by deformation of the air pipe.

[0045] Embodiment 6, on the basis of the above embodiment, one of the output ends 402 of the first driving component 40 is constructed as a rocker arm, at least two first clamping parts 201 are arranged vertically opposite to each other, and a vertical slide groove 501 is opened on the side walls of at least two first clamping parts 201, one end of the rocker arm is slidably accommodated in the slide groove 501, and the other end of the rocker arm is connected to the output end 402 of the first driving component 40, which is suitable for the first clamping part 201 to slide up and down when one end of the rocker arm slides and abuts against the side wall of the slide groove 501.

[0046] When the second clamping part 301 slides to a specific position, it will form a sliding contact with the input end 401 of the first drive assembly 40, triggering the first drive assembly 40 to move. The output end 402 transmits power to the first clamping part 201 through the swing rod, so that one end of the swing rod slides in the slide groove 501, thereby driving the first clamping part 201 to slide up and down to form an adjustable clamping area. When the first fixed side and the second fixed side of the adjustable clamping area simultaneously close the conveying channel, the second drive assembly drives the mounting seat 601 to slide toward the second clamping part 301, so that at least two first clamping parts 201 are close to each other to form a stable clamping state.

[0047] Embodiment 7, as Figure 6 As shown, based on the above embodiment, the slide groove 501 has an avoidance section 70, which is located at one end of the slide groove 501 close to the adjustable clamping area, and the avoidance section 70 is arranged toward the second clamping portion 301. The rocker arm can slide against one side of the avoidance section 70 close to the adjustable clamping area, which is suitable for keeping the conveying channel closed when the mounting seat 601 slides toward the second clamping portion 301.

[0048] In a specific implementation, the avoidance section 70 can be designed to be horizontal. The function of the avoidance section 70 is to prevent the rocker arm from loosening its contact with the first clamping portion 201 during the movement of the mounting seat 601, thereby causing the adjustable clamping area to fail to clamp the air pipe and the mask.

[0049] Specifically, when the mounting seat 601 slides toward the second clamping portion 301 , the rocker arm will slide into the avoidance section 70 and abut against a side of the avoidance section 70 close to the adjustable clamping area, thereby always maintaining the clamping state of the first clamping portion 201 .

[0050] Embodiment 8, based on the above embodiment, the gas pipe clamping mechanism has a rotating rod 80, the rotating rod 80 is mounted in the mounting groove 50, the two ends of the rotating rod 80 are respectively rotatably matched with the side walls of the mounting groove 50, the second clamping part 301 is sleeved on the rotating rod 80, and the first clamping part 201 is threadably matched with the rotating rod 80.

[0051] In a specific implementation, the rotating rod 80 can be a screw, and a rotating bearing can be installed on the side wall of the mounting groove 50. A motor is arranged on the rear end of the storage bracket 10, and the output end 402 of the motor is connected to the screw through a bevel gear transmission mechanism. In this way, when the screw is rotated, the first clamping part 201 will move along the axial direction of the screw, thereby realizing the adjustment of the air pipe and ensuring the stability of the air pipe during the adjustment process.

[0052] Embodiment 9, based on the above embodiment, along the height direction of the adjustable clamping area, the two ends of the avoidance section 70 have a height difference, and the end of the avoidance section 70 close to the adjustable clamping area is located on the low side, and the end of the avoidance section 70 away from the adjustable clamping area is located on the high side.

[0053] The two ends of the avoidance section 70 have a certain height difference, that is, the end close to the adjustable clamping area is lower, and the end away from the adjustable clamping area is higher. Such a design can ensure that during the clamping process, the swing rod always keeps in contact with one side of the avoidance section 70, and can maintain a stable state even when the mounting seat 601 slides.

[0054] When the mounting seat 601 slides toward the second clamping portion 301, the rocker arm will slide into the avoidance section 70 and abut against the side of the avoidance section 70 close to the adjustable clamping area. Since the end of the avoidance section 70 close to the adjustable clamping area is lower, the rocker arm will always abut against the lower side of the avoidance section 70 during the sliding process, thereby ensuring the stability of the first clamping portion 201 during the sliding process. This design can prevent instability caused by changes in the relative position between the rocker arm and the slide groove 501 during the clamping process, thereby ensuring stable clamping of the air pipe during the clamping process.

[0055] Embodiment 10, based on the above embodiment, the avoidance section 70 has an arc portion 90, and the center of the arc portion 90 faces the adjustable clamping area.

[0056] The arc portion 90 of the avoidance section 70 is designed to facilitate the smooth movement of the swing rod in the slide groove 501. The center of the arc portion 90 faces the adjustable clamping area, which means that the curvature direction of the arc portion 90 faces the clamping area. The design of the arc portion 90 can better adapt to the movement trajectory of the swing rod in the slide groove 501, reduce the friction resistance of the swing rod during the sliding process, and help the swing rod always maintain good contact with the slide groove 501.

[0057] Since the center of the arc 90 is facing the adjustable clamping area, the rocker arm will move along the curvature of the arc 90 during the sliding process, ensuring the stability of the rocker arm during the entire movement process. This design helps to reduce the vibration of the rocker arm in the slide groove 501, ensures the stability of the first clamping portion 201 during the sliding process, and thereby improves the accuracy and reliability of the clamping process.

[0058] Working principle:

[0059] When the air pipe needs to be stored, the operator starts the driving mechanism (such as a motor) of the second clamping part 301, and the second clamping part 301 begins to slide along the storage bracket 10. As the second clamping part 301 slides, the air pipe is gradually stored into the delivery channel. When the storage is completed, the second clamping part 301 forms a sliding abutment with the input end 401 of the first drive component 40, and triggers the first drive component 40 to start working, and drives at least two first clamping parts 201 to slide through its output end 402. After the first clamping part 201 slides up and down along the front side of the storage bracket 10, the first fixed side and the second fixed side of the adjustable clamping area work together to close the delivery channel, so that the part between the air pipe and the mask is fixed together to form a whole, thereby avoiding the pulling state between the air pipe and the mask.

The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when a structure is described in conjunction with any embodiment, it is claimed that the structure is implemented in conjunction with other embodiments within the scope of the present invention.
