Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical devices, and particularly relates to an oxygen humidification bottle with a ratchet locking structure. BACKGROUND

[0002] The oxygen humidification bottle is a device in medical equipment, which is used for humidifying oxygen when a patient uses oxygen treatment. Its main function is to increase the humidity of inhaled oxygen to prevent the patient's respiratory tract mucosa from being damaged due to dryness and help maintain the normal physiological function of the respiratory tract. During the process of an ambulance going to the location of a patient, medical staff will prepare the required medical devices in advance to ensure that the patient can be operated in the first time. When oxygen is supplied to the patient, a disposable oxygen humidification bottle is usually selected.

[0003] The existing disposable oxygen humidification bottle usually sets a screw cap at the oxygen inlet to isolate the oxygen humidification bottle from the outside world to prevent bacteria, dust and the like in the outside world from entering the humidification liquid, thereby preventing the patient from being infected during the oxygen inhalation process. When the medical staff are preparing on the ambulance, they will wear medical gloves to prevent the devices from being contaminated by bacteria on their hands. At this time, the medical staff will open, connect and install the oxygen humidification bottle. However, the medical staff cannot quickly rotate the screw cap and connect the oxygen supply pipeline to the oxygen inlet due to the bumps of the vehicle and the medical gloves worn. When the oxygen supply pipeline is installed to the oxygen inlet, the oxygen humidification bottle cannot be used due to the above problems. SUMMARY

[0004] The purpose of the present application is to provide an oxygen humidification bottle with a ratchet locking structure to solve the problems raised in the background.

[0005] In order to achieve the above purpose, the present application provides the following technical scheme: an oxygen humidification bottle with a ratchet locking structure, comprising a bottle body and a top cover, the top cover is fixedly connected to the top opening of the bottle body, the top surface of the top cover is provided with an oxygen inlet, the inside of the oxygen inlet is slidably sleeved with a breather pipe, the side wall of the oxygen inlet is provided with a vertical sliding groove, the outer side surface of the breather pipe is fixedly connected with a vertical sliding block, the vertical sliding block is slidably connected in the vertical sliding groove, the outer side surface of the vertical sliding block is fixedly embedded with a ratchet strip, the side surface of the vertical sliding groove is provided with a horizontal sliding groove, the teeth of the ratchet strip face the horizontal sliding groove, the horizontal sliding groove is slidably connected with a tooth block, and compressed air is filled in the horizontal sliding groove to push the tooth block to move towards the ratchet strip.

[0006] Further comprising a sealing mechanism, the sealing mechanism comprises a convex cavity arranged near the bottom end of the breather pipe and a sealing plug fixedly connected to the inner bottom surface of the bottle body, and the sealing mechanism isolates the inside and outside of the bottle body from the bottom end of the breather pipe.

[0007] Preferably, the top fixing sleeve of the closing plug is provided with a sealing ring, and the inner wall of the breather pipe is provided with an annular sealing groove between the bottom end of the breather pipe and the convex cavity.

[0008] Preferably, the sealing ring is made of elastic material and is in interference fit with the sealing groove, and when the breather pipe is in the open state, the sealing ring is separated from the sealing groove and located in the convex cavity.

[0009] Preferably, the outer side of the breather pipe near the top end is fixedly sleeved with an annular plate, and the bottom surface of the annular plate is elastically connected with the top surface of the top cover through a spring.

[0010] Preferably, the side of the closing plug is provided with a plurality of breather grooves, and the length of the breather grooves is greater than the distance from the convex cavity to the bottom end of the breather pipe.

[0011] Preferably, a humidifier is fixedly sleeved on the breather pipe, and the humidifier is located outside the convex cavity.

[0012] Preferably, an oxygen supply pipe connector is slidably sleeved in the inside of the oxygen inlet, and the oxygen supply pipe connector is in interference fit with the oxygen inlet.

[0013] Preferably, the side of the top cover is provided with an oxygen outlet, and the outer side of the oxygen supply pipe connector is fixedly connected with a plurality of convex blocks.

[0014] The beneficial effects of the present application are as follows:

[0015] 1. When the present application is not used, it is in a closed state, at this time the sealing ring on the closing plug is embedded in the sealing groove, thereby closing the bottom end of the breather pipe, at this time the external air cannot enter the humidifying liquid in the bottle through the top of the breather pipe, thereby eliminating the need to set a sealing cover on the breather pipe, thereby reducing the generation of plastic garbage, and at the same time reducing the operation steps of medical staff installing oxygen humidifying bottles, improving the preparation efficiency of medical staff, and secondly, through the setting of the closing mechanism, when the device needs to be connected to the oxygen supply device, only the oxygen supply pipe connector needs to be pushed down, at this time the oxygen supply pipe connector contacts the annular plate and pushes the annular plate down, thereby driving the entire breather pipe to move down, at this time due to the movement of the breather pipe, the sealing ring is separated from the sealing groove, and part of the breather groove enters the convex cavity, thereby enabling the oxygen provided by the oxygen supply device to enter from the top of the breather pipe and enter the bottle through the breather groove. The above steps enable the present application to be removed and recycled as long as the bottle interior is not in communication with the external air by actually pushing the oxygen supply pipe connector even if it is installed on a fixed support, thereby reducing waste caused by accidental opening, serving as a spare, and the like.

[0016] 2、In the present application, when the ventilation pipe is pushed down by the oxygen supply pipe connector, the ratchet bar embedded in the vertical slider moves downward, at this time, with the downward movement of the ratchet bar, the teeth of the ratchet bar push the tooth block to move into the horizontal sliding groove, the compressed air in the horizontal sliding groove is further compressed, and with the stop of the ventilation pipe, the ratchet bar stops moving, at this time, the compressed air in the horizontal sliding groove expands, thereby pushing the tooth block to move in the direction of the ratchet bar, at this time, the front end of the tooth block is embedded in the teeth of the ratchet bar, so that the ratchet bar cannot move upward, thereby preventing the spring from pushing the annular plate upward to cause the ventilation pipe to move upward again, resulting in the bottom of the ventilation pipe being resealed.

[0017] 3、Finally, the spring in the present application offsets part of the downward pressure on the ventilation pipe, thereby avoiding the ventilation pipe from gradually sliding downward due to vibration and other reasons during storage, transportation and other links, resulting in the ventilation pipe being in an open state when not in use, which causes the humidification liquid in the bottle body to be contaminated, and the oxygen humidification bottle to be wasted.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0028] As shown in the drawings, Figures 1 to 8 The oxygen humidification bottle with ratchet locking structure provided by the embodiment of the present application comprises a bottle body 1 and a top cover 2, the top cover 2 is fixedly connected to the top opening of the bottle body 1, the top surface of the top cover 2 is provided with an oxygen inlet 3, the inside of the oxygen inlet 3 is slidably sleeved with a breather pipe 5, the side wall of the oxygen inlet 3 is provided with a vertical sliding groove 16, the outer side surface of the breather pipe 5 is fixedly connected with a vertical sliding block 14, the vertical sliding block 14 is slidably connected in the vertical sliding groove 16, the outer side surface of the vertical sliding block 14 is fixedly embedded with a ratchet strip 15, the side surface of the vertical sliding groove 16 is provided with a horizontal sliding groove 17, the teeth of the ratchet strip 15 are directed to the horizontal sliding groove 17, the horizontal sliding groove 17 is slidably connected with a tooth block 18, and the horizontal sliding groove 17 is filled with compressed air to push the tooth block 18 to move in the direction of the ratchet strip 15.

[0029] Further comprising a sealing mechanism, the sealing mechanism comprises a convex cavity 6 arranged near the bottom end of the breather pipe 5 and a sealing plug 7 fixedly connected to the inner bottom surface of the bottle body 1, and the sealing mechanism isolates the inside and outside of the bottle body 1 from each other from the bottom end of the breather pipe 5.

[0030] When the present application is not used, it is in a closed state, at this time, the sealing ring 8 on the sealing plug 7 is embedded in the sealing groove 9, thereby sealing the bottom end of the breather pipe 5, at this time, the outside air cannot enter the humidification liquid in the bottle body 1 through the top of the breather pipe 5, thereby eliminating the need to set a sealing cover on the breather pipe 5, thereby reducing the generation of plastic garbage, and at the same time, reducing the operation steps of medical staff in installing the oxygen humidification bottle, and improving the preparation efficiency of medical staff, and secondly, through the setting of the sealing mechanism, when the device needs to be connected to the oxygen supply device, only the oxygen supply pipe joint 19 needs to be pushed down, at this time, the oxygen supply pipe joint 19 is in contact with the annular plate 12 to push the annular plate 12 to move downward, thereby driving the entire breather pipe 5 to move downward, at this time, due to the movement of the breather pipe 5, the sealing ring 8 is separated from the sealing groove 9, and at the same time, part of the breather groove 10 enters the convex cavity 6, thereby enabling the oxygen provided by the oxygen supply device to enter from the top of the breather pipe 5, enter the bottle body 1 through the breather groove 10, the above steps enable the present application to be installed on a fixed support, as long as the inside of the bottle body 1 is not in communication with the outside air by actually pushing the oxygen supply pipe joint 19, the present application can be taken down and recycled, thereby reducing the waste caused by the misoperation, as a spare, and the like.

[0031] When the ventilation pipe 5 is pushed down by the oxygen supply pipe joint 19, the ratchet strip 15 embedded in the vertical sliding block 14 moves downward, at this time, with the downward movement of the ratchet strip 15, the teeth of the ratchet strip 15 push the tooth block 18 to move into the horizontal sliding groove 17, the compressed air in the horizontal sliding groove 17 is further compressed, and when the ventilation pipe 5 stops moving, the ratchet strip 15 stops moving, at this time, the compressed air in the horizontal sliding groove 17 expands, thereby pushing the tooth block 18 to move in the direction of the ratchet strip 15, at this time, the front end of the tooth block 18 is embedded in the teeth of the ratchet strip 15, thereby preventing the ratchet strip 15 from moving upward, and further preventing the vertical sliding block 14 from moving upward, avoiding that when the oxygen supply pipe joint 19 is installed, the spring 13 pushes the annular plate 12 upward, causing the ventilation pipe 5 to move upward again, causing the bottom of the ventilation pipe 5 to be closed again.

[0032] Finally, the spring 13 in the present application offsets part of the downward pressure on the ventilation pipe 5, thereby avoiding that in the process of storage, transportation and the like, the ventilation pipe 5 gradually slides downward due to vibration and the like, causing the ventilation pipe 5 to be in an open state when not in use, and causing the humidifying liquid in the bottle body 1 to be contaminated, thereby causing the oxygen humidifying bottle to be wasted.

[0033] As shown in Figure 5 , the top of the closure plug 7 is fixedly sleeved with a sealing ring 8, the inner wall of the ventilation pipe 5 is provided with an annular sealing groove 9, the sealing groove 9 is located between the bottom end of the ventilation pipe 5 and the protruding cavity 6, the sealing ring 8 is made of elastic material and is in interference fit with the sealing groove 9, and when the ventilation pipe 5 is in an open state, the sealing ring 8 is separated from the sealing groove 9 and located in the protruding cavity 6.

[0034] When the sealing ring 8 is embedded in the sealing groove 9, since the sealing ring 8 is made of elastic material and is in interference fit with the sealing groove 9, the sealing ring 8 blocks the gap between the closure plug 7 and the ventilation pipe 5, thereby avoiding that in a closed state, external air enters the bottle body 1, and also avoiding that the humidifying liquid in the bottle body 1 flows into the inside of the ventilation pipe 5, preventing the humidifying liquid in the bottle body 1 from being contaminated, and as the ventilation pipe 5 is moved downward, the sealing ring 8 is separated from the sealing groove 9, and at this time, the air pressure provided by the oxygen injected from the oxygen inlet 3 pushes the humidifying liquid about to enter the ventilation pipe 5 into the bottle body 1, thereby avoiding that the humidifying liquid contacts the inner wall of the ventilation pipe 5, and preventing the humidifying liquid from being contaminated by the sundries attached to the inside of the ventilation pipe 5.

[0035] As shown in Figures 2 to 8 , the outer side of the ventilation pipe 5 close to the top end is fixedly sleeved with an annular plate 12, the bottom surface of the annular plate 12 is elastically connected with the top surface of the top cover 2 by a spring 13, the annular plate 12 is located in the oxygen inlet 3 and is in interference fit with the oxygen inlet 3.

[0036] The annular plate 12 is arranged to contact the oxygen supply pipe joint 19, so as to move the breather pipe 5 when the oxygen supply pipe joint 19 is pushed, and the spring 13 can push the breather pipe 5 to move upward, so that the spring 13 can offset the pushing force when the breather pipe 5 is pushed by a force less than a certain size, and the closing mechanism is prevented from being opened by mistake due to vibration and the like, so that the humidification liquid in the bottle body 1 is prevented from being polluted, and the humidification liquid is prevented from being polluted by external air, and the patient inhales clean oxygen.

[0037] As shown in Figure 5 The side of the closing plug 7 is provided with a plurality of breather grooves 10, and the length of the breather grooves 10 is greater than the distance from the convex cavity 6 to the bottom end of the breather pipe 5.

[0038] When the bottom end of the breather pipe 5 is closed by the closing mechanism, the sealing ring 8 is embedded in the sealing groove 9, at this time, the breather grooves 10 have no part entering the convex cavity 6, and external air cannot enter the bottle body 1 through the breather grooves 10, so that the humidification liquid in the bottle body 1 is prevented from being polluted, and as the breather pipe 5 is pushed downward, part of the breather grooves 10 enters the convex cavity 6, so that the external input oxygen can enter the humidification liquid along the breather grooves 10 to be humidified, so that the closing device can be opened by simply pushing down, and the use is simple and convenient.

[0039] As shown in Figures 1 to 8 The breather pipe 5 is fixedly sleeved with a humidifier 11, the humidifier 11 is located outside the convex cavity 6, the oxygen inlet 3 is slidably sleeved with the oxygen supply pipe joint 19, the oxygen supply pipe joint 19 is in interference fit with the oxygen inlet 3, the side of the top cover 2 is provided with an oxygen outlet 4, and the outer side of the oxygen supply pipe joint 19 is fixedly connected with a plurality of convex blocks 20.

[0040] Working principle:

[0041] When the present application is used, first, the bottle body 1 is fixed on the bracket for installing the disposable oxygen humidification bottle, then the oxygen supply pipe joint 19 is connected with the oxygen supply equipment, then the oxygen supply pipe joint 19 is inserted between the oxygen inlet 3 and the breather pipe 5, when it is needed to be used, the oxygen supply pipe joint 19 is pushed downward, at this time, the oxygen supply pipe joint 19 pushes the annular plate 12 to move downward, the annular plate 12 pushes the breather pipe 5 to move downward, so that the sealing ring 8 is separated from the sealing groove 9, at this time, part of the breather grooves 10 on the side of the closing plug 7 enters the convex cavity 6, so that the inside of the breather pipe 5 is communicated with the inside of the bottle body 1, at this time, the oxygen entering from the oxygen inlet 3 enters the bottle body 1 to be humidified.

[0042] When the oxygen supply pipe joint 19 is pushed downward, the annular plate 12 and the ventilation pipe 5 are moved downward, and as the ventilation pipe 5 moves, the ratchet bar 15 moves downward together with the ventilation pipe 5. When the ratchet bar 15 contacts the front end of the tooth block 18, the tooth block 18 is pushed to slide into the horizontal sliding groove 17, so as to compress the air in the horizontal sliding groove 17. When the ventilation pipe 5 stops moving, the compressed air expands, so as to push the tooth block 18 to move outward, and then the front end of the tooth block 18 is embedded into the ratchet bar 15, so as to prevent the ventilation pipe 5 from moving upward, thereby avoiding the interruption of oxygen supply caused by the upward movement of the ventilation pipe 5 during oxygen supply.
