Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more specifically, to a multifunctional patient oxygen inhalation device. Background Art

[0002] Oxygen inhalation equipment is a device widely used in cardiology and cardiovascular medicine. As a conventional treatment method, this equipment is mostly connected by an oxygen source and an oxygen mask. Oxygen masks are divided into nasal masks and oronasal masks. Both nasal masks and oronasal masks can improve the utilization rate of accumulated gas, thereby increasing the concentration of inhaled oxygen. It is suitable for patients with dyspnea. When in use, the oxygen mask is covered on the patient's nose and mouth, which can effectively and quickly increase blood oxygen saturation and improve the patient's hypoxic state. It is mostly suitable for critically ill, comatose and postoperative patients. When the patient's condition improves and requires long-term low-flow oxygen inhalation, the oxygen mask can no longer be used, because the patient will feel stuffy at this time, so the oronasal mask must be replaced in time, which undoubtedly causes a waste of medical equipment. Moreover, some patients' conditions are sometimes good and sometimes bad, and they need to replace oxygen inhalation tools many times, which also brings more workload.

[0003] Therefore, in actual use, frequent replacement of masks of different forms will cause certain inconvenience to patients on the one hand, and cause certain waste of medical resources on the other hand. The oxygen mask disclosed in CN117752908B improves the versatility and adaptability of the oxygen mask by setting a structure for free switching between the upper mask body and the lower mask body. However, when the above device is used, the flow of gas between the upper mask body and the lower mask body is controlled by a sealing plug, which will hinder the patient's use and cause certain discomfort to the patient. For this reason, we propose a multifunctional patient oxygen inhalation device. Summary of the invention

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Embodiment 1 further describes a multifunctional patient oxygen inhalation device proposed by the present invention, including an inhalation bottle body 100, an oxygen inhalation tube 101 is connected to one side of the inhalation bottle body 101, a regulating valve 102 is provided on one side of the inhalation bottle body 102, and a noise reduction mechanism 400 is provided inside the inhalation bottle body 100, including an upper cover body 103 and a lower cover body 104, the upper cover body 103 and the lower cover body 104 are detachably connected, a connection part 105 is provided on both sides of the outer side of the upper cover body 103, and a connection part 2 106 is provided on both sides of the outer side of the lower cover body 104, the connection part 105 and the connection part 2 106 are connected by a buckle, and the upper cover body 103 and the lower cover body 104 are detachably connected. A sealing plate 107 is integrally formed in the upper cover body 103, a nasal inhalation area 108 is formed between the upper cover body 103 and the sealing plate 107, a sealing plate 2 109 is integrally formed in the lower cover body 104, an oxygen inhalation area 110 is formed between the lower cover body 104 and the sealing plate 2 109, air outlets 111 are arranged on both sides of the upper cover body 103, an air inlet head 112 is integrally formed on the side wall of the upper cover body 103, one end of the oxygen inhalation tube 101 is connected to the air inlet head 112, a positioning mechanism 200 is arranged between the upper cover body 103 and the lower cover body 104, an adjusting mechanism 300 is arranged in the sealing plate 107, and the positioning mechanism 200 and the adjusting mechanism 300 cooperate with each other;

[0037] In order to prevent the continuous dry oxygen from damaging the patient's respiratory tract, the prior art needs to add an oxygen humidification bottle between the oxygen supply center and the nasal oxygen tube or oxygen mask, so that the continuous dry oxygen can be humidified after passing through the humidifying liquid in the humidification bottle, and then enter the patient's body through the nasal oxygen tube or oxygen mask. However, when the existing oxygen humidification bottle is used, the oxygen comes out from the aeration pipe 402h and the bubbles that rise up from the water will generate a large noise during the movement, affecting the patient's rest. The device is provided with a noise reduction mechanism 400 in the inhalation bottle body 100 to cut the bubbles generated in the water, so that the large bubbles are gradually divided into multiple small bubbles, thereby reducing the noise in the inhalation bottle body 100 and ensuring the quality of the patient's rest.

[0038] The present invention further improves the structure of the oxygen supply mask, and the upper mask body 103 and the lower mask body 104 can be separated from each other, so that the upper mask body 103 can be used as a nasal inhalation mask when in use, and when the upper mask body 103 and the lower mask body 104 are combined together, they can be used as a whole mask. In this way, the device can be used as a nasal inhalation mask or an oronasal mask.

[0039] At the same time, the device further improves the connection method of the upper mask body 103 and the lower mask body 104. By setting a positioning mechanism 200, the upper mask body 103 and the lower mask body 104 are ensured to be quickly installed. At the same time, the device further refines the positioning mechanism 200. When the upper mask body 103 and the lower mask body 104 are connected, a stable gas channel can be formed between the upper mask body 103 and the lower mask body 104, so that when the device is used as an oral and nasal mask, the gas can be communicated. When the upper mask body 103 is used as a nasal suction mask, its gas channel can be quickly closed, thus ensuring the applicability of the device when used;

[0040] Compared with the oxygen mask disclosed in CN117752908B, the positioning mechanism 200 of the device is hidden in the sealing plate 1 107 and the sealing plate 2 109, saving the external structure, so that the device will not affect the use of the patient due to the protrusion of the sealing plug when in use, thereby improving the comfort of the patient;

[0041] The positioning mechanism 200 includes a movable member 201 disposed in the closed plate 107, a resisting member 202 is disposed in the movable member 201, the movable member 201 and the resisting member 202 cooperate with each other, a clamping member 203 is disposed at one end of the resisting member 202, a plug-in member 204 is disposed in the closed plate 109, the clamping member 203 and the plug-in member 204 cooperate to position the device, and the adjustment mechanism 300 includes an annular member 301 disposed in the closed plate 107, an opening and closing member 302 is disposed in the closed plate 107, the annular member 301 and the opening and closing member 302 cooperate with each other, a linkage member 303 is disposed on one side of the annular member 301, and the annular member 301 and the linkage member 303 cooperate with each other;

[0042] Depend on Figures 1 to 12 It can be known that when the device is in use, the sealing plate 107 and the sealing plate 2 109 are staggered and installed, so that the plug-in piece 204 in the sealing plate 2 109 slides in the sealing plate 1 107, and at the same time, through the cooperation of the movable member 201 and the abutment member 202, the clamping member 203 on the abutment member 202 is pressed into the plug-in piece 204, so that the upper cover body 103 and the lower cover body 104 are quickly positioned, and then the locking buckle can be installed on the connecting part 105 and the connecting part 2 106 to realize the rapid locking of the upper cover body 103 and the lower cover body 104, and when the sealing plate 107 and the sealing plate 2 109 are attached to each other, due to the cooperation of the plug-in piece 204 and the linkage piece 303, the linkage piece 303 drives the annular piece 301 to work synchronously, and at this time, under the action of the annular piece 301, the gas channel between the upper cover body 103 and the lower cover body 104 is connected;

[0043] The noise reduction mechanism 400 includes a noise reduction member 401 disposed in the suction bottle body 100, and a partition member 402 is disposed in the noise reduction member 401. The noise reduction member 401 and the partition member 402 cooperate to process the bubbles inside the suction bottle body 100. Figure 3 It can be seen that the present invention provides a noise reduction member 401 and a dividing member 402 in the inhalation bottle body 100, and divides the large bubbles coming out of the aeration tube 402h in multiple levels, thereby reducing the noise generated by the bubbles, so that patients have better comfort when using it.

[0044] Working principle: When in use, the upper mask body 103 of the device can be treated as a nasal suction mask to ensure that the patient is not restricted when eating. When the upper mask body 103 and the lower mask body 104 are combined together, they can be treated as a whole mask. At the same time, when the upper mask body 103 and the lower mask body 104 are installed, the positioning mechanism 200 can be used to quickly position the upper mask body 103 and the lower mask body 104, and then the upper mask body 103 and the lower mask body 104 are locked by the buckle. While the device is positioning, the linkage part 303 and the annular part 301 cooperate to quickly connect the gas channel between the upper mask body 103 and the lower mask body 104. Compared with the prior art, the use of the patient will not be affected by the protrusion of the closure plug when the device is in use, thereby improving the comfort of the patient.

[0045] Embodiment 2

[0046] The following technical features are added on the basis of the first embodiment: the movable member 201 comprises a mounting groove 201a provided in the closing plate 107, the mounting groove 201a protrudes outward and is provided with a notch 201b, two groups of compression springs 201c are fixedly connected in the notch 201b, one end of the two groups of compression springs 201c away from the notch 201b is fixedly connected to a movable block 201d, both sides of the movable block 201d are fixedly connected to limit strips 201e, a through hole 201f is provided in the notch 201b, an expansion buckle 201g is provided in the through hole 201f, one end of the expansion buckle 201g is correspondingly pressed against the outer wall of the movable block 201d, and one end of the abutment block 202a is slidably connected in the closing plate 107;

[0047] Depend on Figures 5 to 12 It can be seen that a square frame-shaped installation groove 201a is provided in the closing plate 107, and a notch 201b is provided at the front end of the installation groove 201a. A movable block 201d is connected to the notch 201b through two sets of compression springs 201c. The two sides of the movable block 201d are fixedly connected to limit bars 201e. When positioning, the expansion buckle 201g can be inserted into the through hole 201f, so that the expansion buckle 201g conflicts with the outer wall of the movable block 201d, so that the extrusion force of the expansion buckle 201g drives the movable block 201d to slide in the closing plate 107;

[0048] The resisting member 202 includes resisting blocks 202a slidably connected to the two sides of the installation groove 201a, and the corresponding ends of the resisting blocks 202a on both sides are provided with limiting grooves 202b, and the limiting strips 201e are correspondingly slidably connected in the limiting grooves 202b, and the clamping member 203 includes strip plates 203a fixedly connected to the resisting blocks 202a on both sides, and the strip plates 203a on both sides are correspondingly provided with sliding grooves 203b, and the ends away from the sliding grooves 203b on both sides are fixedly connected with tension springs 203c, and the tension springs 203c are correspondingly fixedly connected with fixed blocks 203d, and one end of the fixed block 203d is arranged on the inner wall of the installation groove 201a;

[0049] Depend on Figures 7 to 12 It can be seen that two groups of resistance blocks 202a are slidably connected in the installation groove 201a, and the corresponding ends of the two groups of resistance blocks 202a are provided with limit grooves 202b, and the limit strips 201e on both sides of the movable block 201d are slidably connected in the limit grooves 202b. At the same time, the device further defines the resistance blocks 202a, and the resistance blocks 202a on both sides are fixedly connected to the strip plates 203a respectively, and the strip plates 203a are correspondingly slidably connected in the installation groove 201a. The installation groove 201a Sliding grooves 203e are provided on both sides. The sliding grooves 203e are divided into two parts. One is a straight area 203f, so that the limiting plate 204a can stably slide in the straight area 203f, and the other is a limiting area 203g. The limiting area 203g is T-shaped. When the limiting portion 204b on the limiting plate 204a slides to the limiting area 203g, the limiting plate 204a is stuck in the sliding groove 203e, so that the positioning of the closing plate 1 107 and the closing plate 2 109 is achieved;

[0050] During operation, the squeezing force of the expansion buckle 201g drives the movable block 201d to slide in the closed plate 107, and the two groups of compression springs 201c are deformed. At this time, the limit strips 201e on both sides of the movable block 201d are slidably connected in the limit groove 202b. Due to the squeezing force of the movable block 201d, the two groups of resistance blocks 202a move backwards, thereby synchronously driving the strip plate 203a to move backwards. At this time, the tension spring 203c is deformed. The device is provided with multiple groups of springs to ensure that when the expansion buckle 201g is taken out, the movable block 201d has a better reset effect under the restoring force of the spring;

[0051] The insert 204 includes a limiting plate 204a fixedly connected to both sides of the upper end surface of the closing plate 109, and the upper end surfaces of the limiting plates 204a on both sides are integrally formed with limiting portions 204b, and the limiting portions 204b on both sides are correspondingly slidably connected in the limiting area 203g, and a corresponding side of the limiting plates 204a on both sides is provided with a slot 204c, and one end of the strip plate 203a is correspondingly against the slots 204c on both sides;

[0052] Depend on Fig. 9It can be known that the device fixes the limiting plates 204a on both sides of the closing plate 109, the limiting plates 204a are rectangular parallelepiped structures, and the upper end surface of the limiting plates 204a is integrally formed with a T-shaped limiting portion 204b. When the limiting plates 204a move along the straight area 203f to the limiting area 203g, the limiting portion 204b is correspondingly stuck in the limiting area 203g, and the corresponding sides of the limiting plates 204a on both sides are provided with a slot 204c, so that one end of the strip plate 203a is correspondingly pressed against the slots 204c on both sides;

[0053] Working principle: It can be known from Example 1 that when positioning the upper cover body 103 and the lower cover body 104, the device displaces the upper cover body 103 and the lower cover body 104 so that the limit plates 204a on both sides of the closing plate 2 109 slide in the closing plate 1 107. When they are just in contact, the limit plates 204a can stably slide in the straight area 203f, and the limit plates 204a move along the straight area 203f to the limit area 203g, so that the limit part 204b is correspondingly stuck in the limit area 203g. At this time, the upper cover body 103 and the lower cover body 104 have been initially positioned. Then, the expansion buckle 201g is inserted from the through hole 201f, so that the expansion buckle 201g contacts the movable block 201d, and the tension spring 203c is deformed. At this time, the limit strips 201e on both sides of the movable block 201d are slidably connected in the limit grooves 202b. Due to the squeezing force of the movable block 201d, the two groups of abutment blocks 202a move backwards, thereby synchronously driving the two groups of strip plates 203a to move backwards, and the tension spring 203c is deformed. At this time, one end of the strip plate 203a is correspondingly pressed against the card grooves 204c on both sides, thereby realizing the locking of the upper cover body 103 and the lower cover body 104;

[0054] When disassembling, it is only necessary to cut off the head of the expansion buckle 201g. At this time, the resistance effect on the movable block 201d disappears. Under the recovery of multiple sets of springs, the movable block 201d retracts into the slot 201b, and the strip plates 203a on both sides are reset. Fig. 9 As shown, at this time, the positioning state of the upper cover body 103 and the lower cover body 104 is released, and then the buckles in the connecting part 105 and the connecting part 2 106 are removed, so as to separate the upper cover body 103 and the lower cover body 104.

[0055] Embodiment 3

[0056] The following technical features are added on the basis of the second embodiment: the annular member 301 comprises an annular strip 301a arranged in the mounting groove 201a, a gear ring 301b is fixedly connected to the outer wall of the annular strip 301a, six groups of connecting plates 301c are fixedly connected around the inner wall of the annular strip 301a, a circular plate 301d is fixedly connected between the six groups of connecting plates 301c, a circular hollow hole 301e is arranged in the middle of the circular plate 301d, and corresponding sliding holes 301f are arranged in the plurality of groups of connecting plates 301c, and when the annular strip 301a rotates, the six groups of connecting plates 301c are driven to rotate synchronously, and the circular plate 301d in the center of the six groups of connecting plates 301c rotates synchronously;

[0057] The opening and closing member 302 includes a straight groove 302a which is circumferentially arranged on the mounting groove 201a. Two adjacent groups of straight grooves 302a are symmetrically arranged, and the two adjacent groups of straight grooves 302a intersect each other. The angle between the two adjacent groups of straight grooves 302a is an obtuse angle. One group of straight grooves 302a is in contact with two groups of straight grooves 302a. The corresponding sliding connections in the plurality of groups of straight grooves 302a are connected with opening and closing plates 302b. A single straight groove 302a corresponds to an opening and closing plate 302b one by one. The opening and closing plate 302b includes a closed surface 1 302c and a closed surface 2 302d. The closed surface 1 302c and the closed surface 2 302d are connected to each other. 2d form an acute angle, the adjacent opening and closing plates 302b are fitted together through the closing surface 1 302c and the closing surface 2 302d, and the multiple opening and closing plates 302b form an air outlet 302e, and the opening and closing plates 302b are fixedly connected with a sliding rod 302f, one end of the sliding rod 302f is slidably connected in the straight groove 302a, and the other end of the sliding rod 302f is arranged in the sliding hole 301f, and the corresponding positions of the closing plate 1 107 and the closing plate 2 109 are provided with a connecting hole 302g, and the connecting hole 302g and the air outlet 302e are on the same axis, and the diameter of the connecting hole 302g is larger than the air outlet 302e;

[0058] Depend on Figures 8 to 12 It can be seen that there are six groups of opening and closing plates 302b, and two adjacent groups of opening and closing plates 302b are attached to each other. The opening and closing plates 302b include a closed surface 1 302c and a closed surface 2 302d. The closed surface 1 302c of one group of opening and closing plates 302b is in contact with the closed surface 2 302d of the opening and closing plate 302b in contact with it. Since the sliding rods 302f on the opening and closing plates 302b are slidably connected in the sliding holes 301f and the straight grooves 302a respectively, when the annular strip 301a rotates, the opening and closing plates 302b on the sliding rods 302f move along the direction of the corresponding straight grooves 302a. When the movement reaches the limit, the air outlet holes 302e between the six groups of opening and closing plates 302b are opened or closed.

[0059] The linkage member 303 includes a baffle 303a fixedly connected to the mounting groove 201a, a long strip plate 303b is integrally formed on the baffle 303a, a movable spring 303c is fixedly connected to the side wall of the baffle 303a, one side of the movable spring 303c is fixedly connected to the plug plate 303d, the plug plate 303d is slidably connected to the long strip plate 303b to ensure the stability of the plug plate 303d when moving, a rack 303e is fixedly connected to the side wall of the plug plate 303d, the rack 303e is meshed with the gear ring 301b, and a wedge-shaped portion 303f is formed at one end of the plug plate 303d. It is explained here that the end diameter of the wedge-shaped portion 303f is larger than the diameter of the slot 204c, so that when the wedge-shaped portion 303f is resisted by the limiting plate 204a, the wedge-shaped portion 303f will not be inserted into the slot 204c, thereby affecting the overall operation of the device;

[0060] Depend on Figures 8 to 12 It can be seen that the baffle plate 303a and the long strip plate 303b form an L-shaped structure and are fixedly connected in the installation groove 201a. The long strip plate 303b is slidably connected with the plug plate 303d, and the plug plate 303d is fixedly connected to the baffle plate 303a through the movable spring 303c. When the limit plate 204a slides in the closing plate 107, the limit plate 204a contacts the wedge-shaped portion 303f. Under the pressure of the limit plate 204a, the plug plate 303d on the wedge-shaped portion 303f moves in the long strip plate 303b. At this time, the movable spring 303c is deformed. Since the rack 303e on the plug plate 303d is engaged with the gear ring 301b, the annular bar 301a on the gear ring 301b rotates.

[0061] Working principle: It can be known from Examples 1 and 2 that when the upper cover 103 and the lower cover 104 are positioned, the limit plate 204a slides in the closing plate 107, and the limit plate 204a contacts the wedge-shaped portion 303f. Under the pressure of the limit plate 204a, the plug plate 303d on the wedge-shaped portion 303f moves in the long strip plate 303b. At this time, the movable spring 303c is deformed, and the rack 303e on the plug plate 303d is engaged with the gear ring 301b, so that the annular strip 301a on the gear ring 301b rotates, and the rotation of the annular strip 301a drives the six groups of connecting plates 301c synchronously. The circular plate 301d in the center of the six groups of connecting plates 301c rotates synchronously. Since the sliding rod 302f on the opening and closing plate 302b is slidably connected in the sliding hole 301f and the straight groove 302a respectively, when the annular strip 301a rotates, the opening and closing plate 302b on the sliding rod 302f moves along the direction of the corresponding straight groove 302a. When the movement reaches the limit, the air outlet holes 302e between the six groups of opening and closing plates 302b are opened or closed. In this way, when the upper cover body 103 and the lower cover body 104 are completely fitted, the air outlet holes 302e are opened to allow gas to circulate between the upper cover body 103 and the lower cover body 104.

[0062] When the upper mask body 103 and the lower mask body 104 are separated, the movable spring 303c returns to the original position, driving the plug plate 303d to retract, and the rack 303e engages with the gear ring 301b, so that the annular strip 301a on the gear ring 301b rotates in the opposite direction. When the annular strip 301a rotates, the six groups of connecting plates 301c rotate synchronously. At this time, the air outlet 302e is closed, so that the upper mask body 103 can be used as a separate nasal suction mask.

[0063] Embodiment 4

[0064] The following technical features are added on the basis of the third embodiment: the noise reduction member 401 includes a cavity 401a provided in the suction bottle body 100, a noise reduction tube 401b is formed integrally with the top of the inner wall of the cavity 401a, the noise reduction tube 401b is composed of a first expansion cavity 401c, a contraction cavity 401d and a second expansion cavity 401e, the dividing member 402 includes a noise reduction hole 402a provided in the first expansion cavity 401c, six groups of cutting pieces 402b are fixedly connected to the inner side of the noise reduction hole 402a, and the six groups of cutting pieces 402b are fixedly connected to the inner side of the noise reduction hole 402a. A cutting block 402c is fixedly connected between the groups of cutting pieces 402b, a sieve plate 1 402d is fixedly connected to the inner wall of the first expansion chamber 401c, and a plurality of groups of sieve holes 1 402e are arranged on the sieve plate 1 402d, a sieve plate 2 402f is fixedly connected to the second expansion chamber 401e, and a plurality of groups of sieve holes 2 402g are arranged in the sieve plate 2 402f, and the area of ​​the sieve holes 2 402g is smaller than that of the sieve holes 1 402e, so as to ensure the cutting effect of bubbles, and an aeration pipe 402h is connected to the side wall of the suction bottle body 100;

[0065] Depend on Figure 2 It can be seen that the noise reduction pipe 401b is gourd-shaped, consisting of a first expansion chamber 401c, a contraction chamber 401d and a second expansion chamber 401e. The variable diameter structure of expansion to contraction and then to expansion is used to increase the contact area between oxygen and the water surface, which can effectively reduce noise. At the same time, the device further limits the structure of the noise reduction component 401. By setting a dividing component 402, large bubbles are cut multiple times to reduce the noise generated by the bubbles, while ensuring sufficient humidification of oxygen. It can be specifically divided into three stages. The first stage is to break up the large bubbles generated by the aeration pipe 402h. The second stage is to cut the bubbles through the sieve hole 402e in the sieve plate 402d. The third stage is accelerated through the contraction part so that the cut bubbles are cut again through the sieve hole 402g, so that the bubbles are dispersed as much as possible, thereby achieving the effect of reducing noise.

[0066] Working principle: When in use, the aeration pipe 402h transports the gas into the cavity 401a, generating a large number of bubbles, and then the cutting blade 402b on the cutting block 402c cuts the large bubbles. Since the bottom ends of the sieve plate 1 402d and the sieve plate 2 402f are both curved surfaces, the contact area of ​​the bubbles is increased, so that the upward bubbles undergo secondary cutting by the sieve hole 1 402e and the sieve hole 2 402g, thereby achieving the effect of reducing the bubbles, which not only reduces the noise, but also ensures sufficient humidification of the oxygen.

[0067] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
