Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a nebulizer or atomizer specifically applicable to treatment purposes. Background Art

[0002] A spray head is a commonly used medical device. A reverse-disassembling spray head is a spray head with high safety that can only be disassembled unidirectionally. During use, the reverse-disassembling spray head is placed in the patient's oral cavity and then connected to an external power mechanism through a connecting tube. The power mechanism sprays the vaporized liquid medicine into the patient's respiratory tract through the reverse-disassembling spray head, so as to achieve the purpose of atomizing treatment for the patient.

[0003] The patient's tongue touches the spray head and blocks it, or food residues enter the oral cavity due to the patient's coughing, nausea, etc., blocking the spray head. Due to the patient's physical weakness, the patient cannot timely feedback to the operator, resulting in poor treatment effect.

[0004] Therefore, in order to solve the technical problem that a physically weak patient cannot timely feedback the blockage of the spray head, a flux-detectable reverse-disassembling spray head is urgently needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flux-detectable reverse-disassembling spray head to solve the above problems.

[0006] In order to achieve the above purpose, the utility model provides the following technical solution:

[0007] A flux-detectable reverse-disassembling spray head includes an atomizing head, an intermediate tube and a connecting tube. The atomizing head is communicated with the connecting tube through the intermediate tube. A blocking member is arranged inside the intermediate tube, and the intermediate tube is communicated with an in-tube air pressure detecting member through a pipe fitting. A through hole is arranged on the blocking member.

[0008] The in-tube air pressure detecting member is communicated with the intermediate tube near the connecting tube through a pipe fitting, and the connection part of the pipe fitting and the intermediate tube is located between the blocking member and the connecting tube.

[0009] The in-tube air pressure detecting member includes a check valve, an adapter and a detector.

[0010] The pipe fitting is communicated with the check valve through an adapter, and the check valve is communicated with the detector through another adapter.

[0011] Further, the pipe fitting is made of a flexible material. The two ends of the adapter are threadedly connected to the check valve, and the detector is separated from the check valve.

[0012] Further, the pipe fitting is specifically made of silicone rubber, and the number of detectors is not less than one.

[0013] Further, one end of the pipe fitting away from the one-way valve is connected to the side wall of the intermediate pipe. The detection member is made of a flexible material, and the detection member is communicated with the air outlet of the one-way valve through an adapter.

[0014] Further, the detection member is specifically an airbag.

[0015] Further, the blocking member is located inside the intermediate pipe, and the blocking member is fixedly connected to the intermediate pipe.

[0016] Further, the blocking member is made of a rigid material, and the blocking member contacts the end of the atomizing head.

[0017] Further, the material of the blocking member is metal or plastic. There are a plurality of holes in the blocking member, and the sizes of the holes in the blocking member are matched with the size of the outlet of the atomizing head.

[0018] The beneficial effects of the present utility model are as follows: A flux-detectable anti-disassembly spray head is provided. By the mutual cooperation of the atomizing head, the intermediate pipe, the blocking member, the detection member and the connecting pipe, a flux-detectable anti-disassembly spray head is made to replace the ordinary anti-disassembly spray head, so that during the use of the anti-disassembly spray head, the operator can clearly and intuitively find that the atomizing pipe is blocked. When the anti-disassembly spray head is blocked and cannot normally supply the liquid medicine to the patient, the operator can easily find it, improving the treatment effect.

[0023] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0024] Externally, due to the patient's weak body, the patient cannot control their tongue and oral cavity during the treatment process, causing the tongue to block the atomizing head of the atomizing tube, thereby making the atomizing tube unable to be used normally. At the same time, due to physiological phenomena such as the patient coughing and regurgitating, solid particles will appear in the patient's oral cavity. When a large number of solid particles enter the atomizing tube, they will block the anti-disassembly spray head and cannot provide the atomized medicine to the patient normally.

[0025] As Figure 1 As shown, in at least one embodiment, a detectable flux anti-disassembly spray head is provided, including an atomizing head 11, an intermediate tube 12, and a connecting tube 13. The atomizing head 11 is communicated with the connecting tube 13 through the intermediate tube 12 and is used as a channel for the medicine mist. A blocking member 3 is arranged inside the intermediate tube 12 to block solid particles from entering the connecting tube 13 and the detection hole from the oral cavity. When solid particles enter the atomizing tube 1 and make it unable to be used normally, the intermediate tube 12 is communicated with the in-tube air pressure detection component 4 through a pipe fitting 2 and is used as a channel for the medicine mist. When the medicine mist cannot be provided to the atomizing head 11 at the required flow rate, it can reach the in-tube air pressure detection component 4, enabling the operator to see the expansion of the detection component 43, facilitating the operator to handle it in a timely manner, removing the atomizing tube 1 from the patient's mouth, and promptly dealing with the solid particles in the patient's oral cavity and cleaning the spray head.

[0026] A through hole 31 is arranged on the blocking member 3 and is used as a channel for the medicine mist.

[0027] The in-tube air pressure detection component 4 is communicated with the intermediate tube 12 near the connecting tube 13 through a pipe fitting 2. The detection hole where the pipe fitting 2 is connected to the intermediate tube 12 is located between the blocking member 3 and the connecting tube 13 and is used as a channel for the medicine mist. When the medicine mist cannot be provided to the atomizing head 11 at the required flow rate, it can reach the in-tube air pressure detection component 4. When the pressure in the in-tube air pressure detection component 4 reaches 0.6 MPa, the one-way valve 42 opens and the medicine mist passes through the one-way valve 42 and reaches the detection component 43 to make the detection component 43 expand, enabling the operator to see it and facilitating the operator to adjust in a timely manner.

[0028] As Figure 2 As shown, the in-tube air pressure detection component 4 includes a one-way valve 42, a connecting piece 41, and a detection component 43, which are used to ensure that the detection component 43 can expand under a certain pressure and prevent the detection component 43 from expanding when the atomizing tube 1 is not blocked;

[0029] The pipe fitting 2 is communicated with the one-way valve 42 through a connecting piece 41, and the one-way valve 42 is communicated with the detection component 43 through another connecting piece 41 and is used as a channel for the medicine mist. When the medicine mist cannot be provided to the atomizing head 11 at the required flow rate, it can reach the in-tube air pressure detection component 4, enabling the operator to see the expansion of the detection component 43 and facilitating the operator to adjust in a timely manner.

[0030] The material of the pipe fitting 2 is a flexible material, which is used to conveniently adjust the positions of the pipe fitting 2 and the in-pipe air pressure detection component 4. The adapter 41 is threadedly connected to the two ends of the one-way valve 42. The detection component 43 is separated from the one-way valve 42 and is used to block the medicine mist from entering the interior of the detection component 43 when the pressure received by the one-way valve 42 is not large.

[0031] Specifically, the material of the pipe fitting 2 is silicone rubber, and the number of the detection components 43 is not less than one.

[0032] One end of the pipe fitting 2 away from the one-way valve 42 is connected to the detection hole on the side wall of the intermediate pipe 12. The detection component 43 is made of a flexible material and is used to ensure that the detection component 43 will expand after the medicine mist enters the detection component 43. The detection component 43 is communicated with the air outlet of the one-way valve 42 through the adapter 41.

[0033] Specifically, the detection component 43 is an airbag, which is used to ensure that the detection component 43 will expand after the medicine mist enters the detection component 43.

[0034] As Figure 3 shown, the blocking component 3 is located inside the intermediate pipe 12, and the blocking component 3 is fixedly connected to the intermediate pipe 12 and is used to block large-sized solid particles from entering the intermediate pipe 12.

[0035] The blocking component 3 is made of a rigid material, and the blocking component 3 contacts the end of the atomizing head 11.

[0036] The material of the blocking component 3 is metal or plastic. There are multiple through holes 31 on the blocking component 3, which are used to ensure that the medicine mist can pass through the blocking component 3 normally. The size of the through holes 31 on the blocking component 3 matches the size of the outlet of the atomizing head 11.

[0037] The working principle of the present utility model is as follows: Before starting to use the detectable flux type anti-disassembly spray head, connect the detectable flux type anti-disassembly spray head to an external power mechanism, that is, connect the connecting pipe 13 to the external power mechanism that provides liquid medicine; When starting to use the detectable flux type anti-disassembly spray head: The operator inserts the detectable flux type anti-disassembly spray head into the patient's oral cavity, making the atomizing head 11 face the patient's respiratory tract. At this time, the in-pipe air pressure detection component 4 is located outside the patient's oral cavity. Then, the operator controls the external power mechanism to provide medicated mist into the connecting pipe 13. During this process, the medicated mist is discharged into the patient's respiratory tract through the detectable flux type anti-disassembly spray head. When the patient's tongue blocks the atomizing head 11 or solid particles in the patient's oral cavity enter the atomizing head 11 when the patient coughs, the solid particles stay at the intersection of the atomizing head 11 and the middle pipe 12 after contacting the blocking member 3 and cannot reach the middle pipe 12. The solid particles block most of the through holes 31 of the blocking member 3. When there are too many solid particles in the atomizing head 11 or the patient's tongue continuously blocks the atomizing pipe 1, at this time, the medicated mist pressure provided by the external power mechanism to the connecting pipe 13 remains unchanged, and the medicated mist pressure in the middle pipe 12 continues to increase. During this process, the medicated mist in the middle pipe 12 generates pressure on the one-way valve 42 through the pipe fitting 2; When the pressure received by the one-way valve 42 continues to increase, when the medicated mist cannot wash away the solid particles on the blocking member 3 or the patient's tongue continuously blocks the atomizing pipe 1, the one-way valve 42 is forced to open too much, so that the medicated mist reaches the detection member 43 through the one-way valve 42 and the adapter 41, causing the detection member 43 to expand. When the operator visually observes that the detection member 43 becomes larger, it can be known that the medicated mist cannot be normally delivered into the patient's oral cavity, that is, the atomizing pipe 1 is blocked. Stop supplying medicated mist to the detectable flux type anti-disassembly spray head, replace the new detectable flux type anti-disassembly spray head or clean the detectable flux type anti-disassembly spray head and then place it back into the patient's oral cavity; Then continue the atomization treatment for the patient, and repeat the above steps until the work is completed.

[0038] The above embodiments are used to further illustrate the present utility model, but do not limit the present utility model to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be understood to be within the protection scope of the present utility model.
