Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an auxiliary sputum drainage device. Background Art

[0002] In the medical field, especially in the treatment and care of respiratory diseases, assisting patients in sputum drainage is a crucial task. Poor sputum drainage may lead to airway obstruction, which in turn may cause serious consequences such as dyspnea, aggravated infection, and even respiratory failure. Currently, conventional sputum drainage assistance methods mainly rely on medical staff manually patting the patient's chest to help the patient expel sputum.

[0003] However, the manual operation method requires medical staff to have certain skills and experience to ensure that the patting force and position are appropriate, so as to achieve an effective sputum drainage effect. Secondly, the manual patting method has a high labor intensity, causing a great burden on the wrists and arms of medical staff, and long-term operation is likely to lead to muscle strain and other occupation-related diseases.

[0004] Based on this, in order to effectively reduce the labor intensity of medical staff, we propose an auxiliary sputum drainage device. Summary of the Invention

Detailed implementation manners

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Refer to Figure 1-10 For an embodiment of the present invention, it discloses an auxiliary sputum drainage device. Refer to Figure 1 、 Figure 2 , specifically, the device includes a bag body 1 configured with at least one sliding chamber 10, and the bag body 1 is bound to the human chest through a binding assembly 2;

[0036] Wherein, a striking mechanism 3 is movably connected in the sliding chamber 10 and a guiding mechanism 4 is installed on the striking mechanism 3. Of course, in this embodiment, a single sliding chamber 10 and a single striking mechanism 3 are taken as examples. Preferably, in this embodiment, the sliding chamber 10 can also be set to two, and the two sliding chambers 10 are separated by a partition member inside the bag body 1, so that the auxiliary sputum drainage operation of two striking mechanisms 3 can be formed. In addition, those skilled in the art can also adaptively adjust the number of the sliding chamber 10 and the striking mechanism 3 on the basis of this structure. Since it is only an equivalent replacement in terms of quantity, no more description will be made here;

[0037] Refer to Figure 2 、 Figure 3 , the guiding mechanism 4 is used to drive the striking mechanism 3 to move in the sliding chamber 10, and the striking mechanism 3 is connected to a water circuit mechanism 5 and a water hammer effect is formed inside it, that is, the present invention realizes the reciprocating strike on the patient's chest similar to the hand patting by means of the water hammer effect generated by the striking mechanism 3, thereby assisting in sputum drainage. The striking mechanism 3 realizes a striking force in the direction towards the chest. At the same time, the striking mechanism 3 can move freely in the sliding chamber 10 to simulate the moving path when a doctor uses the hand to pat the patient.

[0038] It should be noted that since the bag body 1 in this embodiment needs to be worn on the chest, in order to ensure the adaptation to the chest, the bag body 1 described in this embodiment can be set as a flexible bag body, such as a plastic bag, etc. Since the position of the human chest is relatively flat, it will not interfere with the movement of the above-mentioned striking mechanism 3.

[0039] Refer to Figure 4 , Figure 6 , in some embodiments, the striking mechanism 3 in the present invention includes a back plate 31 and a water tank 32 formed in front of the back plate 31. The water tank 32 and the back plate 31 are integrally formed, and an inertia block 34 is movably connected inside the water tank 32 through a spring 33.

[0040] Referring to Figure 6 , specifically, in this embodiment, the water sump 32 is arranged in a cylindrical structure, and the inertia block 34 is also arranged in a circular column structure. The spring 33 is connected between the bottom of the inertia block 34 and the back plate 31. To further improve the installation stability of the spring 33, in this embodiment, an installation groove may be opened at the bottom of the inertia block 34, and the upper end of the spring 33 is placed in the installation groove, so as to form telescopic positioning of the spring 33 and avoid the problem of the spring 33 shifting during movement.

[0041] Referring to Figure 3 , preferably, in this embodiment, the waterway mechanism 5 includes a water tank 51 and a water pump 52 placed in the water tank 51. The output end of the water pump 52 is connected with a water outlet pipe 53, and the water outlet pipe 53 is communicated with the water sump 32. The water in the water sump 32 is also returned to the water tank 51 through a water return pipe 54.

[0042] Referring to Figure 4 、 Figure 5 , of course, in order to facilitate the threading constraint of the water outlet pipe 53 and the water return pipe 54, in this embodiment, the water outlet pipe 53 and the water return pipe 54 can be connected together to avoid the problem of scattered pipelines. In addition, the water outlet pipe 53 and the water return pipe 54 are fixedly connected to the bag body 1, and the fixed connection method can avoid the problem of water leakage at the penetration of the water outlet pipe 53 and the water return pipe 54 through the bag body 1.

[0043] Referring to Figure 4 , specifically, in this embodiment, the water tank 51 is placed outside the bag body 1, and the water outlet pipe 53 and the water return pipe 54 penetrate through the bag body 1 and are connected to the outside of the water sump 32;

[0044] Referring to Figure 6 , wherein, the water outlet pipe 53 and the water return pipe 54 are arranged oppositely. It should be noted that in this embodiment, both the water outlet pipe 53 and the water return pipe 54 include a hose section and a hard pipe section. The hose section is used to keep the water outlet pipe 53 and the water return pipe 54 deformable and bendable during the movement of the entire striking mechanism 3, so as to adapt to the movement of the entire striking mechanism 3 during movement. In addition, the hard pipe section is for the subsequent installation of the one-way valve plate 55 and the drain valve plate 56 to ensure the installation stability of the valve plate.

[0045] Referring to Figure 2 , preferably, in this embodiment, a display screen 58 is also installed in front of the water tank 51. During actual use, the start and stop of the water pump 52 and the electromagnet 57 and the time can be controlled through the display screen, so as to operate the beating force, beating frequency, and moving path of the entire striking mechanism 3.

[0046] Reference Figure 6 , Figure 7 On the basis of the above embodiment, the waterway mechanism 5 in the present invention further includes a one-way valve plate 55 rotatably connected to the inside of the tail end of the water outlet pipe 53, the one-way valve plate 55 allows the water outlet pipe 53 to be conducted toward one side of the water tank 32, the return pipe 54 is rotatably connected to the inside of the water tank 32 with a drain valve plate 56 and an electromagnet 57 fixedly installed, the electromagnet 57 is used to drive the drain valve plate 56 to rotate to open and close the internal pipeline of the return pipe 54, refer to Figure 8 , Figure 9 Specifically, in this embodiment, a waist groove is provided in the middle of the drain valve plate 56, and two limit columns are fixed at intervals on the axial end of the electromagnet 57. The axial end of the electromagnet 57 is inserted into the waist groove, and the two limit columns are respectively stopped on both sides of the drain valve plate 56. In this way, when the axial end of the electromagnet 57 is telescopically moved, its axial end will drive the drain valve plate 56 to rotate through the two limit columns and the waist groove. When the drain valve plate 56 rotates, the water path of the return pipe 54 and the water tank 32 bracket can be cut off or conducted.

[0047] Reference Figure 7 To go further, in this embodiment, a rotating frame 531 is fixedly installed inside the water outlet pipe 53, and the one-way valve plate 55 rotates inside the rotating frame 531, and the bottom of the one-way valve plate 55 conflicts with the bottom of the rotating frame 531, wherein a compression spring 532 is fixedly installed between the top of the one-way valve plate 55 and the rotating frame 531, that is, when the water in the water tank 51 is pumped into the water tank 32, the liquid will enter the water tank 32 along the water outlet pipe 53, and the one-way valve plate 55 can be driven to rotate under the push of the liquid pressure. At this time, its upper end squeezes the compression spring 532. On the contrary, when the drain valve plate 56 is closed, there is no flow pressure inside the water tank 32, and the one-way valve plate 55 can also be reset under the action of the compression spring 532 to intercept the water path.

[0048] When assisting in expectoration, firstly, the liquid in the water tank 51 is pumped from the water outlet pipe 53 to the water tank 32 by the water pump 52, and a part of the water flow will enter the guide mechanism 4 to drive the striking mechanism 3 to move in the sliding chamber 10, and the other part of the water flow will pass through the one-way valve plate 55 in the water outlet pipe 53. The one-way valve plate 55 can achieve a faster throttling effect, and the liquid can only flow in but not out, and the liquid flowing in at a high speed can enter the water tank 32;

[0049] Of course, a drain valve plate 56 is installed inside the return water pipe 54. The drain valve plate 56 is controlled by an electromagnet 57 and can achieve automatic high-speed closing and opening. In the default state, the drain valve plate 56 is pushed open and conducted by the electromagnet 57. In this state, after the liquid passes through the water storage tank 32, it will be discharged from the drain valve plate 56 along the return water pipe 54 at high speed;

[0050] That is, in the default state, the liquid flows at high speed between the outlet pipe 53, the water storage tank 32, and the return water pipe 54. When it is necessary to perform a hitting action on the patient's chest, the drain valve plate 56 can be instantaneously closed by controlling the electromagnet 57 while the liquid is flowing at high speed. At this time, the liquid will be instantaneously blocked in the water storage tank 32, and a relatively large impact force will be generated inside the water storage tank 32 when it is blocked, forming a water hammer effect;

[0051] The above-mentioned impact force acts between the inner wall of the water storage tank 32 and the inertia block 34. Since the inertia block 34 has a certain mass, the acceleration of the inertia block 34 is relatively slow, that is, it is in a relatively static state relative to the entire back plate 31. At this time, the above-mentioned impact force will drive the back plate 31 and the water storage tank 32 except the inertia block 34 to move in the opposite direction, that is, push the entire back plate 31 to pat the patient;

[0052] Refer to Figure 4 Preferably, in the present invention, an airbag 36 is fixedly installed on the end face of the back plate 31. The airbag 36 is sleeved outside the water storage tank 32 and the guide tank 41. The airbag 36 is of an annular structure. Since during the sputum drainage process, the doctor will form an annular shape with the hand to hit the patient's chest to achieve a better effect, an airbag 36 is installed at the front end of the back plate 31. The airbag 36 not only plays a buffering role to prevent harm to the patient during the hitting process, but also can simulate the hitting effect of the hand, reflecting the principle of engineering human body simulation and making the treatment process more natural and comfortable.

[0053] Further, when the hitting mechanism 3 drives the back plate 31 and the airbag 36 to pat the patient under the water hammer effect, the drain valve plate 56 can be controlled by the electromagnet 57 to rotate and open at this time, and the liquid inside the water storage tank 32 flows normally. At this time, the inertia block 34 is pushed back to its original position by the spring 33 to prepare for the next hitting action. That is, by quickly opening and closing the drain valve plate 56 in this way, a continuous water hammer effect can be formed inside the hitting mechanism 3, and the patient can be patted.

[0054] The advantages of using the water hammer effect are as follows: The hitting mechanism 3 can generate a relatively large impact force in a relatively small space; moreover, the hitting force and frequency can be controlled by controlling the flow rate of the water and the opening and closing time of the valve, so as to meet different treatment requirements.

[0055] Reference Figure 6 、 Figure 8 、 Figure 10 In some embodiments, the guiding mechanism 4 in the present invention includes a guiding chamber 41 formed on the back plate 31. The space between the upper ends of the guiding chamber 41 and the back plate 31 is sealed. In this embodiment, the cross-section of the guiding chamber 41 is a U-shaped structure;

[0056] A plurality of guiding channels 35 communicating with the outer side surface are formed inside the back plate 31. The guiding chamber 41 is communicated with the water outlet pipe 53. A plurality of through holes 42 communicating with the guiding channels 35 are provided inside the guiding chamber 41. A valve control assembly for controlling the opening and closing of the through holes 42 is installed in the guiding chamber 41.

[0057] Preferably, there are eight guiding channels 35 along the circumferential part of the outer side surface of the back plate 31 in this embodiment. The eight guiding channels 35 are distributed in a cross shape. In this way, the movement direction of the entire striking mechanism 3 can be controlled by controlling the water flow in different guiding channels 35.

[0058] Reference Figure 10 On the basis of the above embodiment, the valve control assembly in the present invention includes a guiding valve plate 43 rotatably connected inside the guiding chamber 41. The guiding valve plate 43 covers the upper part of the through hole 42;

[0059] An electromagnet two 44 is further installed inside the guiding chamber 41. The electromagnet two 44 is used to drive the guiding valve plate 43 to rotate.

[0060] As described above, since the guiding chamber 41 and the water outlet pipe 53 are conducted in this embodiment, when the water outlet pipe 53 drives the striking mechanism 3 to move, part of the water flow will enter the guiding chamber 41. Since the guiding channels 35 on the back plate 31 and the guiding chamber 41 are connected through the through holes 42, the opening and closing of different guiding valve plates 43 can be controlled by the electromagnet two 44, so that the corresponding guiding channels 35 spray out water flow, and the striking mechanism 3 can be driven to move in the opposite direction, so that it can move freely inside the sliding chamber 10.

[0061] Of course, during operation, when controlling the movement of the striking mechanism 3, the guiding mechanism 4 will always spray water into the bag body 1. In this embodiment, the bag body 1 and the water tank 51 can be connected by pipelines, and a pressure switch can be installed on the connecting pipeline between the two. That is, when the water pressure inside the bag body 1 is too high, the excess water flow will be discharged into the water tank 51.

[0062] It should be noted that the binding component 2 in this embodiment includes straps connected to both sides of the bag body 1, and the two straps are connected and fixed through a connecting piece. Of course, the connecting piece described in this embodiment can be a buckle or a Velcro piece, and its specific connection method is a conventional means for those skilled in the art, so it will not be elaborated here.

[0063] In summary, the auxiliary sputum drainage device in the present invention realizes the function of chest percussion and sputum drainage through a wearable design. When in use, the device is placed in front of the patient's chest. Water is supplied to the percussion mechanism 3 through the waterway mechanism 5, and the percussion of the patient's chest is realized through the water hammer effect formed inside the percussion mechanism 3. A closed circulation system is formed between the percussion mechanism 3 and the waterway mechanism 5, which can continuously provide power support for sputum drainage treatment; at the same time, the percussion mechanism 3 of the present invention is controlled by means of the guiding mechanism 4. When assisting in the operation, the movement of the percussion mechanism 3 inside the sliding chamber 10 can be controlled, so as to improve the comprehensiveness of the percussion area to optimize the sputum drainage effect.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
