Description

Technical Field

[0001] The invention relates to the technical field of sputum suction for severe pneumonia patients, and in particular to a sputum suction device for severe pneumonia patients capable of preventing stress response. Background Art

[0002] Patients with severe pneumonia will have symptoms such as coughing and expectoration. Some patients with severe pneumonia will have difficulty in coughing up sputum due to respiratory failure. At this time, they need to be treated with a sputum suction device under the guidance of a doctor in critical care medicine. The sputum suction device can effectively clear the sputum in the patient's lungs, ventilate the lungs, and facilitate the relief of the condition. The existing sputum suction devices for patients with severe pneumonia still have some problems when used, such as; The patent name disclosed in the prior art with the announcement number "CN118001474A" is "A portable sputum suction device for clinical nursing", which discloses that after assembly, the expander is inserted into the mouth of the person to achieve the purpose of positioning opening, and then the sputum suction tube is passed through the connection frame and enters the oral pharynx to open the mouth of the person to prevent the sputum suction tube from being difficult to insert and being bitten flat in the middle. If the sputum is too deep during sputum suction, the pharynx of the person is stimulated by mechanical stimulation after locking, thereby helping the person to cough and improving the efficiency of sputum suction. For the subsequent removal process of the sputum suction tube, a wiping and retention structure is added to scrape and retain the mucus on the outer surface, and the retained mucus will not enter the mouth, thereby improving the cleaning degree; When the above-mentioned sputum suction device is used, the expander needs to be inserted into the mouth of the person, and the sputum suction tube needs to be passed through the connecting frame and then enter the oral pharynx. In this way, the use of the connecting frame and the expander will block the view of a part of the patient's oral cavity, so that the medical staff may accidentally touch other areas of the oral cavity when inserting the sputum suction tube into the oral pharynx, which will cause a stress reaction in the patient, and then affect the medical staff to insert the sputum suction tube into the oral pharynx, which will not only affect the subsequent sputum suction operation, but also may cause damage to the inside of the patient's oral cavity; Therefore, we propose a sputum suction device for severe pneumonia patients that can prevent stress response, so as to solve the above-mentioned problems. Summary of the invention

[0015] (2) The synchronous adjustment component includes a fixed frame, a threaded rod and a connecting block. By manually rotating the threaded rod, the two sets of connecting blocks and the connecting rod can be driven to move toward each other at the same time, and then the two sets of connecting rods can drive the upper expansion block and the lower expansion block to move toward each other at the same time, so as to facilitate the expansion adjustment of the tooth expansion component; (3) The synchronous adjustment component includes a fixed tube and a second adjustment piston component. The upper opening block and the opening block can be moved synchronously toward each other by simply pushing and then rotating the second adjustment piston component, making the adjustment more convenient. (4) The auxiliary downward pressing mechanism includes a vertical rod, which is driven by the control block to move upward, so that the vertical rod applies an upward thrust to one end of the tongue depressor, thereby causing the tongue depressor to rotate with the rotating rod as the center, and then causing the other end of the tongue depressor to apply a downward pressure to the tongue. The operation is convenient and no additional power source is required. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 12 , the present invention provides the following technical solutions: Embodiment 1: The sputum suction device for severe pneumonia patients to prevent stress reaction in this embodiment can open the inside of the oral cavity to the maximum extent, so as to prevent the medical staff from blocking the field of vision when inserting the sputum suction tube 5 into the oral pharynx of the patient, thereby preventing the patient from having a stress reaction. For the specific structure, refer to the attached Figure 1-Figure 6 As shown, it includes an outer shell 1, and a liquid storage bottle 4 installed in a groove opened on the upper right side of the outer shell 1. The upper left side of the liquid storage bottle 4 is connected to the connecting pipe 3 through a joint, and the left end of the connecting pipe 3 is connected to the air filter 2 above the outer shell 1; the upper right side of the liquid storage bottle 4 is connected to the sputum suction tube 5 through a joint, and the outer side of the sputum suction tube 5 is provided with a tooth opening component for opening the oral cavity, and a synchronous adjustment component is installed on the outer side of the tooth opening component; a storage groove 8 for placing the tooth opening component is opened inside the front side of the outer shell 1 ; The lower part of the synchronous adjustment component is connected to the storage groove 8 through a connecting line; a tongue depressing block 12 for pressing down the tongue is installed on the right side of the lower depressing block 9 in the teeth depressing component through a mounting mechanism, and an auxiliary pressing mechanism is installed on the tongue depressing block 12. The teeth depressing component includes an upper depressing block 6 arranged above the suction tube 5, and also includes a lower depressing block 9 arranged below the suction tube 5. The upper depressing block 6 and the lower depressing block 9 are both arranged in an arc shape, and the outer ends of the upper depressing block 6 and the lower depressing block 9 are both installed with a connecting rod 10 in an "L" shape.

[0020] The upper support block 6, the lower support block 9 and the tongue depressor 12 are all made of medical polyethylene plastic material. The mounting mechanism includes screws, and the tongue depressor 12 is connected to the lower support block 9 by screws. The synchronous adjustment component includes a connecting block 11 installed at the front end of the connecting rod 10, and also includes a fixed frame 7 arranged on the outside of the connecting block 11. A threaded rod 71 is installed inside the fixing frame 7, and the outer side of the threaded rod 71 is threadedly connected to the connecting block 11. The lower interior of the lower support block 9 is hollow, and a control block is arranged inside the lower support block 9. 91, an air storage bag 94 is installed in the lower support block 9 above the control block 91, and mounting rods 92 with an "L" shaped structure are installed on both sides of the control block 91. The upper end of the mounting rod 92 is connected to the groove opened in the lower support block 9 through a connecting spring 93. The air storage bag 94 and the control block 91 are both arranged in an arc shape. The auxiliary pressing mechanism includes a tongue pressing pad 121 installed under the tongue pressing block 12. The interior of the tongue pressing pad 121 is a hollow structure. One end of the tongue pressing pad 121 is connected to the interior of the air storage bag 94 through a ventilation pipe 122.

[0021] First, the entire severe pneumonia patient is moved into the working area with the suction device, and then the outer shell 1 is placed. At this time, one end of a new suction tube 5 is connected to the joint above the liquid storage bottle 4, and then the opening and closing door at the front end of the storage slot 8 is opened, and the tooth stretching assembly in the storage slot 8 is taken out. The patient opens his mouth, and then the upper stretching block 6 and the lower stretching block 9 in the tooth stretching assembly are placed inside the patient's mouth. At this time, the upper surface of the upper stretching block 6 is in contact with the patient's upper teeth, and the lower surface of the control block 91 below the lower stretching block 9 is in contact with the patient's lower teeth.

[0022] Then the medical staff manually rotates the threaded rod 71 in the synchronous adjustment assembly. When the threaded rod 71 rotates, it drives the two connecting blocks 11 connected by the outer thread to move toward each other synchronously, and then the two connecting blocks 11 drive the two connecting rods 10 to move toward each other synchronously. At this time, the upper connecting rod 10 drives the upper support block 6 to move upward, so that the upper support block 6 applies an upward thrust to the upper teeth, and the lower connecting rod 10 drives the lower support block 9 to move downward, so that the lower support block 9 applies a downward thrust to the lower teeth. At the same time, when the lower support block 9 moves downward, the lower teeth will apply an upward thrust to the control block 91, so that the control block 91 moves upward in the lower support block 9, and then the mounting rods 92 on both sides of the control block 91 move upward in the groove in the lower support block 9, and at the same time, the connecting spring 93 is squeezed and stored to ensure that the control block 91 moves upward steadily, and at this time the control block 91 squeezes the air storage bag 94 in the lower expansion block 9, so that the gas in the air storage bag 94 enters the tongue depressor pad 121 below the tongue depressor block 12 through the ventilation tube 122. At this time, the volume of the tongue depressor pad 121 with a hollow structure inside expands, so that the tongue depressor pad 121 applies a downward pressure on the tongue, and then the tongue depressor pad 121 is used in conjunction with the tooth expansion component to expand the patient's mouth to the maximum extent, so that the patient's mouth is not blocked, so that the medical staff can pass the suction tube 5 through the gap between the upper expansion block 6 and the lower expansion block 9, and then insert it into the patient's oral pharynx, avoiding the suction tube 5 accidentally touching other parts of the oral pharynx during the insertion process and causing the patient to have a stress response, so as to facilitate the suction operation in the later stage.

[0023] After the suction tube 5 is inserted, the switch on the outer shell 1 is started, and the negative pressure adjustment knob is adjusted through the pressure indicator on the outer shell 1, so that negative pressure is generated in the liquid storage bottle 4 through the connecting tube 3, and then the suction tube 5 can suck the patient's sputum into the liquid storage bottle 4 (since this part is a prior art, it will not be introduced in detail here).

[0024] The upper expansion block 6, the lower expansion block 9 and the control block 91 are made of medical polyethylene plastic material. A layer of medical silicone pad can be installed on the upper surface of the upper expansion block 6, the lower surface of the control block 91 and the lower surface of the tongue depressor 12 to protect the patient's teeth.

[0025] Embodiment 2: The sputum suction device for severe pneumonia patients to prevent stress reaction in this embodiment, on the basis of embodiment 1, discloses another structure of synchronous adjustment component, which makes it more convenient to adjust the opening of the tooth opening component without long-term rotation adjustment. The specific structure is shown in the attached Figure 7-10As shown, the synchronous adjustment component includes a fixed tube 14 installed on the front side of the connecting rod 10, and the fixed tube 14 is arranged in a "T" shape. Two first regulating piston assemblies 13 are symmetrically installed inside the vertical area of ​​the fixed tube 14, and the outer end of the first regulating piston assembly 13 is connected to the connecting rod 10; a second regulating piston assembly 16 is installed in the horizontal area of ​​the fixed tube 14, and a fixed plate 15 is fixed to the outer end of the horizontal area of ​​the fixed tube 14, and two groups of first card grooves 151 and second card grooves 152 are opened inside the outer side surface of the fixed plate 15, the interior of the first card groove 151 is connected with the interior of the second card groove 152, the outer side surface of the first card groove 151 is open, and the outer side surface of the arc-shaped second card groove 152 is not open; two clamping blocks 161 are symmetrically installed on the outer end of the second regulating piston assembly 16, and the clamping blocks 161 are matched with the first card groove 151 in a concave-convex manner.

[0026] When the tooth expansion assembly needs to be expanded and adjusted, the second regulating piston assembly 16 is manually pushed and then rotated, so that the second regulating piston assembly 16 pushes part of the gas between the two first regulating piston assemblies 13, so that the two first regulating piston assemblies 13 move toward each other synchronously, thereby making the two first regulating piston assemblies 13 drive the upper expansion block 6 and the lower expansion block 9 to move toward each other synchronously, and when the second regulating piston assembly 16 rotates, it will drive the clamping block 161 to rotate together, so that the clamping block 161 rotates from the first clamping groove 151 to the second clamping groove 152, thereby fixing the position of the second regulating piston assembly 16 after being pushed, which is convenient to operate.

[0027] Embodiment 3: The sputum suction device for severe pneumonia patients to prevent stress reaction in this embodiment discloses another auxiliary pressing mechanism of structure on the basis of embodiment 1, which is convenient for the tongue pressing block 12 to press down the tongue part well. The specific structure is shown in the attached Figure 11-Figure 12As shown, the mounting mechanism includes a rotating rod 17 installed in a groove opened on the right side of the lower support block 9, the rotating rod 17 passes through one end of the tongue pressing block 12, one end of the tongue pressing block 12 is inserted into the lower support block 9, and a vortex spring 171 is nested and connected to the outer side of one end of the rotating rod 17. The auxiliary pressing mechanism includes a vertical rod 95 installed in the middle position above the control block 91, and one end of the tongue pressing block 12 is arranged above the vertical rod 95. The tongue pressing block 12 forms a rotating structure through the vertical rod 95. When the lower teeth drive the control block 91 to move upward, the control block 91 is rotated. Block 91 drives the upper vertical rod 95 to move upward, and then the vertical rod 95 applies an upward thrust to one end of the tongue depressor 121, so that the tongue depressor 121 rotates with the rotating rod 17 as the center. At this time, the vortex spring 171 accumulates force, and then the other end of the tongue depressor 121 applies a downward pressure on the tongue. As a result, the tongue depressor 121 and the tooth expansion component are used in conjunction to expand the patient's mouth to the maximum extent, so that the inside of the patient's mouth is not blocked, which is convenient for the subsequent suction operation, thereby completing a series of tasks.
