Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a tracheotomy tube blocking test device. Background Art

[0002] In modern medicine, tracheotomy is widely used in various respiratory diseases and emergency treatment to ensure the patient's airway is unobstructed and effectively ventilated. However, tracheotomy patients often face a series of challenges during the postoperative recovery process, especially when temporarily blocking the tracheal tube, the temporary blocking device of the prior art has many shortcomings. Traditional test tube blocking devices usually adopt a simple connection method, most of which are to connect the test blocking tube by inserting it into the opening part of the tracheal tube. Although this connection method is easy to operate, it is easy to loosen when the patient coughs or moves due to the lack of an effective locking mechanism, which not only reduces the airtightness of the airway, but also may cause air pollution, increase the risk of infection, and even cause accidental suffocation in extreme cases. In addition, the existing test tube blocking devices often fail to effectively remove pollutants such as particles, bacteria and viruses in the air, and cannot provide patients with an ideal breathing environment, thereby increasing the probability of respiratory infection. Therefore, those skilled in the art propose a test tube blocking device for a tracheotomy tube to solve the above problems. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a test tube plugging device for a tracheotomy tube, which solves the problem that the connection mode of the test tube plugging device in the prior art is unstable and easily causes falling off.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a tracheotomy tube blocking test device, comprising a tube, a second connecting part is fixedly connected to the top of the tube, two card slots are symmetrically provided on the top of the second connecting part, and the longitudinal section of the card slot is L-shaped, a first connecting part is provided on the top of the second connecting part, and two card blocks are symmetrically fixedly connected to the bottom of the first connecting part, and the shape of the card blocks matches the shape of the internal groove of the card slot, an adjustment component is installed at the bottom of the tube, and the adjustment component is used to adjust the airflow size, and a filter component is installed inside the tube, and the filter component is used to filter air and reduce the irritation of drugs to the nasal mucosa.

[0005] Preferably, the adjustment assembly comprises an adjustment block, the outer surface of the adjustment block is provided with two guide grooves, the inner side of the guide groove is slidably connected with a connecting column, and the outer middle side of the connecting column is fixedly connected with an adjustment knob.

[0006] Preferably, a first threading hole is provided at the top of the adjusting block, a second threading hole is provided at the bottom of the adjusting block, and an outer surface of the adjusting knob is provided with anti-slip grooves.

[0007] Preferably, the filter assembly comprises a filter membrane, the filter membrane is fixedly connected to the inner side of the sleeve, and the bottom end of the filter membrane is fixedly connected to a thermal insulation sponge.

[0008] Preferably, a sealing groove is formed on the top of the second connecting portion, and a sealing gasket is fixedly connected to the inner side of the first connecting portion, and the sealing gasket is arranged inside the sealing groove.

[0009] Preferably, the guide groove is arranged obliquely, and the outer surface of the connecting column contacts the inner wall of the guide groove.

[0010] A method for using a tracheotomy tube blocking test device comprises the following steps:

[0011] Step 1: First, align the card block at the bottom of the first connection part with the card slot at the top of the second connection part, and gently rotate the first connection part so that the outer protrusion of the card block can be screwed into the groove inside the card slot, completing the snap connection between the first connection part and the second connection part, so that the first connection part and the second connection part are more tightly connected to prevent the first connection part from falling off when the patient coughs or changes body position;

[0012] Step 2: Install a filter membrane and a thermal insulation sponge on the inner side of the cannula so that the patient can breathe in or out through the filter membrane and the thermal insulation sponge, thereby filtering the air and reducing the stimulation of the drug to the nasal mucosa, while maintaining the internal air pressure of the patient stable;

[0013] Step 3: Move the adjusting knob upward or downward to drive the connecting column to move along the inner wall of the guide groove. Since the inner wall of the guide groove is inclined, when the adjusting knob moves upward, the adjusting knob will contact and squeeze the conduit, reducing the airflow inside the conduit. On the contrary, when the adjusting knob moves downward, the adjusting knob and the conduit no longer contact each other, increasing the airflow inside the conduit.

[0014] The present invention provides a tracheotomy tube blocking test device, which has the following beneficial effects:

[0015] 1. The present invention can ensure the close connection between the test tube blocking device and the tracheal cannula by adding a buckle connection component. The traditional temporary blocking device lacks stability and is easily ineffective due to severe coughing, causing airway contamination or accidental suffocation. Through the buckle design, when the patient coughs, the tube blocking device can be kept in place and is not easy to fall off. At the same time, the patient can feel more comfortable during use and reduce the psychological burden.

[0016] 2. The present invention can effectively remove particles, bacteria, viruses and other pollutants in the air by adding a filter component, so that the patient's respiratory tract can be better protected and the probability of respiratory system infection can be reduced. At the same time, the filter component has humidification and heating functions, thereby ensuring that the air entering the airway maintains appropriate temperature and humidity. In this way, the patient's respiratory tract is kept moist and the patient's airway discomfort and irritation are reduced.

[0017] 3. The present invention can adjust the airflow inside the trachea by adding an adjustment component. By adjusting the airflow, the patient can gradually adapt to the ventilation conditions of the airway, thereby reducing dependence on external support. The overall structure is compact and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings of the present invention specification 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.

[0026] Example:

[0027] Please refer to the attached Figure 1 - Attachment Figure 6The embodiment of the present invention provides a tracheotomy tube blocking test device, including a tube 1, a second connecting portion 202 is fixedly connected to the top of the tube 1, two card slots 204 are symmetrically provided on the top of the second connecting portion 202, and the longitudinal section of the card slot 204 is L-shaped. A first connecting portion 201 is provided on the top of the second connecting portion 202, and two card blocks 203 are symmetrically fixedly connected to the bottom of the first connecting portion 201, and the shape of the card blocks 203 matches the shape of the internal groove of the card slot 204. An adjusting component is installed at the bottom of the tube 1, and the adjusting component is used to adjust the airflow size. A filter component is installed inside the tube 1, and the filter component is used to filter air to reduce the irritation of drugs to the nasal mucosa.

[0028] Specifically, the first connection part 201 is adapted to the second connection part 202, and a sealing gasket 7 is fixedly connected inside. A clamping block 203 is provided at the bottom thereof, which is used to be snap-connected with the clamping slot 204 at the top of the second connection part 202. During the connection process, the user first aligns the clamping block 203 at the bottom of the first connection part 201 with the clamping slot 204 at the top of the second connection part 202. At this time, the gap between the clamping block 203 and the clamping slot 204 is precisely designed to achieve smooth docking.

[0029] The user gently rotates the first connection part 201, and the outer protrusion of the block 203 is gradually inserted into the groove inside the slot 204 through rotation. The rotation action makes the block 203 fit tightly with the slot 204 to form a firm buckle connection. This buckle connection not only improves the stability of the connection, but also prevents loosening or falling off due to external forces (such as the patient's cough).

[0030] Please refer to the attached Figure 1 and attached Figure 4 The adjustment assembly includes an adjustment block 301, and two guide grooves 302 are provided on the outer surface of the adjustment block 301. A connecting column 304 is slidably connected to the inner side of the guide groove 302, and an adjustment knob 303 is fixedly connected to the outer middle side of the connecting column 304. A first threading hole 8 is provided on the top of the adjustment block 301, a second threading hole 9 is provided on the bottom of the adjustment block 301, and an anti-slip pattern is provided on the outer surface of the adjustment knob 303.

[0031] Specifically, by moving the adjusting knob 303 upward or downward, the connecting column 304 is driven to move along the inner wall of the guide groove 302. Since the inner wall of the guide groove 302 is inclined, when the adjusting knob 303 moves upward, the adjusting knob 303 will contact and squeeze the catheter, making the airflow inside the catheter smaller. On the contrary, when the adjusting knob 303 moves downward, the adjusting knob 303 and the catheter no longer contact each other, making the airflow inside the catheter larger. By adjusting the size of the airflow, the patient can gradually adapt to the ventilation conditions of the airway, thereby reducing dependence on external support. In the initial stage, the doctor can set a lower airflow, and then gradually increase the airflow as the patient's respiratory function gradually recovers. This can effectively avoid sudden dyspnea or excessive ventilation, and help patients smoothly transition to no longer relying on artificial ventilation.

[0032] Please refer to the attached Figure 5 The filter assembly includes a filter membrane 4, which is fixedly connected to the inner side of the sleeve 1, and a thermal insulation sponge 5 is fixedly connected to the bottom end of the filter membrane 4.

[0033] Specifically, the patient inhales external air through the tracheal cannula and passes through the filter membrane 4. The filter membrane 4 uses its efficient filtering performance to intercept particulate matter and pathogens in the airflow to ensure that the air entering the airway is clean. The microporous structure of the filter membrane 4 can effectively block bacteria and viruses without affecting the smooth flow of air. The filtered airflow then passes through the thermal insulation sponge 5, which absorbs external heat and keeps the airflow warm, preventing cold air from directly entering the patient's airway. The structure of the sponge ensures that the airflow maintains appropriate humidity when passing through, reducing irritation to the airway.

[0034] Please refer to the attached Figure 5 A sealing groove 6 is formed at the top of the second connecting portion 202 , and a sealing gasket 7 is fixedly connected to the inner side of the first connecting portion 201 , and the sealing gasket 7 is arranged inside the sealing groove 6 .

[0035] After the snap connection is completed, the sealing gasket 7 on the inner side of the first connecting part 201 is pressed into the sealing groove 6 on the top of the second connecting part 202. The elastic design of the sealing gasket 7 can fit tightly with the inner wall of the sealing groove 6, thereby forming a sealing effect, preventing airflow leakage or the entry of contaminants, and ensuring smooth airflow and cleanliness of the tracheal tube.

[0036] Please refer to the attached Figure 1 , Attachment Figure 3 and attached Figure 4 The guide groove 302 is inclined, and the outer surface of the connecting column 304 contacts the inner wall of the guide groove 302 .

[0037] Specifically, the inner wall of the guide groove 302 is inclined, and this design can effectively guide the movement direction of the connecting column 304, and at the same time, the inclined structural characteristics are used to achieve fine adjustment of the airflow. The outer surface of the connecting column 304 contacts the inner wall of the guide groove 302, and the airflow is adjusted by its movement. The column design is sturdy and durable, and can withstand frequent adjustment operations.

[0038] A method for using a tracheotomy tube blocking test device comprises the following steps:

[0039] Step 1: First, align the block 203 at the bottom of the first connection part 201 with the slot 204 at the top of the second connection part 202, and gently rotate the first connection part 201 so that the outer protrusion of the block 203 can be screwed into the groove inside the slot 204, completing the snap connection between the first connection part 201 and the second connection part 202, so that the first connection part 201 and the second connection part 202 are more tightly connected to prevent them from falling off when the patient coughs or changes body position;

[0040] Step 2: Install the filter membrane 4 and the thermal insulation sponge 5 on the inner side of the sleeve 1, so that the patient can pass through the filter membrane 4 and the thermal insulation sponge 5 during the inhalation or exhalation process, thereby filtering the air, reducing the stimulation of the drug to the nasal mucosa, and maintaining the internal air pressure of the patient stable;

[0041] Step three, by moving the adjusting knob 303 upward or downward, the connecting column 304 is driven to move along the inner wall of the guide groove 302. Since the inner wall of the guide groove 302 is inclined, when the adjusting knob 303 moves upward, the adjusting knob 303 will contact and squeeze the conduit, so that the airflow inside the conduit becomes smaller. On the contrary, when the adjusting knob 303 moves downward, the adjusting knob 303 and the conduit no longer contact each other, so that the airflow inside the conduit becomes larger.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
