Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a tracheostomy tube anti-sputum spray device. Background Technology

[0002] According to literature reports, 1% to 2% of stroke patients require tracheotomy, thus necessitating long-term indwelling tracheostomy tubes. During the patient's recovery period, dressing changes are required. During this process, sputum from the patient's throat can easily be ejected from the tracheostomy tube. This sputum, carrying pathogens, can contaminate the ward or operating room, affecting the health of others and causing inconvenience. Additionally, when the patient coughs, sputum may be sprayed out through the tube opening, soiling bed sheets and other items, affecting the ward environment, and increasing the risk of infection.

[0003] Chinese Patent No. CN212347392U discloses a tracheostomy cannula anti-sputum splash protection device, including a cannula, a sputum collector at the top of the cannula, and a collection cylinder threadedly connected to the bottom of the sputum collector. A conical cover is fixedly connected at the center of the sputum collector, and the conical cover has air grooves arranged in a circular array. A limiting block is welded to the bottom of the collection cylinder. The device fixes the connecting pipe at the bottom of the collection cylinder to the cannula via a threaded connection. When the patient coughs, the coughed-up sputum flows outward through the cannula and is connected to the collection cylinder. After the tube enters the sputum collector, it comes into contact with the conical hood. The sputum adheres to the conical hood and, over time, slides down the inner wall of the conical hood. After sliding to the edge, it drips between the limiting block and the collection cylinder. The air grooves on the conical hood are for the flow of air for the patient's breathing, preventing the sputum from obstructing the airflow. When it is necessary to clean the sputum collector, the connecting tube is unscrewed from the sleeve, and the collection cylinder and the sputum collector are loosened and separated. This allows the sputum inside the collection cylinder to be cleaned, and at the same time, the sputum collector and the collection cylinder are sterilized and disinfected for reuse.

[0004] However, in the above-mentioned device, the cone-shaped hood is placed in the sputum collector and has an air groove. When the patient exhales, the sputum adheres to the cone-shaped hood. When inhaling, the presence of the air groove will still generate suction on the sputum, which may cause the sputum to flow back into the trachea. At the same time, if the patient breathes rapidly, the sputum may be ejected from the air groove.

[0005] Based on the above problems, this utility model proposes a tracheostomy tube anti-sputum spray device to prevent sputum from being sprayed out with breathing when the patient is breathing or changing dressings. Utility Model Content

[0006] To address the aforementioned problems, this invention proposes a tracheostomy tube anti-sputum spray device. This structure can solve the problem of sputum being sprayed out with breathing when the patient is breathing or changing dressings.

[0007] To solve the above problems, the technical solution of this utility model is as follows:

[0008] This utility model discloses a tracheostomy tube anti-sputum-spraying device, including a connecting tube, a sputum collection tube, and an air outlet. One end of the connecting tube is connected to the tracheal tube sleeve, and the second end is sealed to the sputum collection tube. The sputum collection tube is provided with an air outlet, and a sputum-blocking plate is provided inside the sputum collection tube. The sputum-blocking plate and the inner wall of the sputum collection tube form a space that is sealed at the top and all sides and open at the bottom.

[0009] Furthermore, the air outlet is provided with multiple outlets, and each outlet is provided with a sputum-blocking sheet.

[0010] Furthermore, the sputum-blocking plate is shaped like a trumpet, wider at the top and narrower at the bottom, with openings at both the top and bottom, and the smaller opening at the top is sealed to connect to the air outlet.

[0011] Furthermore, the sputum separator is tile-shaped, with its top and sides sealed to the inner wall of the sputum collection tube, and its bottom open.

[0012] Furthermore, it also includes a cover and threads. The cover is fixed to the bottom of the sputum collection tube by the threads. With the cover, when a certain amount of sputum accumulates inside the sputum collection tube, the cover can be opened to clean the sputum collection tube in a timely manner, avoiding bacterial contamination.

[0013] Furthermore, it also includes an air outlet tube, one end of which is located inside the sputum-blocking sheet through an air outlet hole, and the other end is located outside the sputum-collecting tube.

[0014] Furthermore, the connecting tube is located on one side of the sputum collection tube and is tangential to the sputum collection tube; this arrangement allows the patient's exhaled air to rotate when it enters the sputum collection tube, so that the sputum carried in the air can be better adsorbed onto the inner wall of the sputum collection tube.

[0015] Furthermore, the bottom opening of the sputum separator is spaced 2-3 cm apart from the cover; this distance is used to collect sputum and also to prevent sputum from splashing out of the sputum collection tube.

[0016] Furthermore, the connecting tube is L-shaped; this design allows the sputum collection tube to be placed more vertically, preventing it from tipping over and causing sputum leakage, which could affect the external environment.

[0017] Furthermore, the cross-sectional area of ​​the connecting pipe is S1, the cross-sectional area of ​​the "+" shape between the multiple sputum-sparing plates and the sputum-collecting tube is S2, and the sum of the cross-sectional areas of the multiple spaces formed by the sputum-sparing plates and the inner wall of the sputum-collecting tube with top and four sides sealed and bottom open is S3, where S2 < S1 < S3.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. This utility model sets a sputum-blocking plate inside the sputum collection tube and moves the air outlet upward into the sputum-blocking plate. When the patient breathes and has sputum, the sputum is stuck to the bottom of the sputum collection tube, while the air is exhaled. At the same time, this design can also prevent sputum from flowing back when the patient inhales.

[0020] 2. This utility model, with its multiple air vents, can prevent patients from being affected by accidental blockage of the air vent during use.

[0021] 3. This utility model, through its cover design, allows for quick cleaning of sputum generated in the sputum collection tube, preventing bacterial growth. Attached Figure Description

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings: Example 1

[0033] like Figures 1-3 As shown:

[0034] A tracheostomy tube anti-sputum-spraying device includes a connecting tube 1, a sputum collection tube 2, an air outlet 3, and a sputum-blocking plate 4. One end of the connecting tube 1 is connected to the tracheal tube, and the second end is connected to the sputum collection tube 2. The sputum collection tube 2 is a hollow cylinder. Four air outlets 3 are evenly arranged on the same horizontal plane on the inner wall of the sputum collection tube 2. A sputum-blocking plate 4 is provided above each air outlet 3. The sputum-blocking plate 4 is located on the inner wall of the sputum collection tube 2, is tile-shaped, and forms a space with the inner wall of the sputum collection tube 2 that is sealed at the top and all sides and open at the bottom.

[0035] The connecting tube 1 is used to seal the sputum collection tube 2 to the tracheal tube. The sputum collection tube 2 is used to remove sputum expelled with the patient's breathing. The air outlet 3 is used to allow the patient to breathe. The sputum barrier 4 is used to prevent sputum expelled with the patient's breathing from reaching the outside through the air outlet 3.

[0036] In this embodiment, the bottom of the sputum collection tube 2 is closed, and the lowest opening of the sputum separator 4 is 2 cm away from the bottom of the sputum collection tube 2. After the patient's breathing gas enters the sputum collection tube 2 through the connecting tube 1, it flips from the bottom of the sputum collection tube 2 into the space between the sputum separator 4 and the inner wall of the sputum collection tube 2, and then is discharged through the air outlet 3. When the gas contains the patient's sputum, the sputum will come into contact with the bottom of the sputum collection tube 2 under the action of the gas flow rate and stick to the bottom of the sputum collection tube 2. The remaining gas is discharged through the air outlet 3.

[0037] like Figure 5 As shown, the cross-sectional area of ​​the connecting tube 1 is S1, the cross-sectional area of ​​the "+" shape between the four sputum-sparing plates 4 and the sputum-collecting tube 2 is S2, and the sum of the cross-sectional areas of the multiple spaces formed by the sputum-sparing plates 4 and the inner wall of the sputum-collecting tube 2 with top and perimeter seals and bottom openings is S3. In this embodiment, S1 > S2. During exhalation, as the gas enters the sputum-collecting tube 2, the gas flow rate is accelerated, and the sputum contained in the gas can be adhered to the bottom of the sputum-collecting tube 2 with sufficient force. During inhalation, the gas flow rate decreases slightly as it travels from the sputum-collecting tube 2 to the connecting tube. This design prevents sputum from flowing back into the trachea at the bottom of the sputum collection tube 2 due to excessive suction. It also requires that S2 < S3, reducing the gas flow rate during this section to prevent excessively fast flow that could cause some sputum to be carried out through the air outlet 3. Furthermore, the areas of these three components must satisfy the condition that S2 < S1 < S3, ensuring that the outflowing gas velocity is lower than the inflow velocity. This design ensures that sputum adheres to the bottom of the sputum collection tube 2 during exhalation and prevents sputum from flowing back into the trachea during inhalation. Example 2

[0038] like Figure 4 As shown:

[0039] The difference between this embodiment and Embodiment 1 is that the connecting tube 1 is an "L"-shaped design. This device has four air outlets evenly distributed on the sputum collection tube 2, ensuring that the patient can breathe through the air outlets 3 under any circumstances. This avoids the air outlets 3 from being blocked due to accidents during the recovery process, which would affect the patient. At the same time, the "L"-shaped connecting tube 1 changes the traditional straight design, which can reduce the burden on the incision site during patient use. In addition, the "L"-shaped connecting tube 1 can help the sputum collection tube 2 to be placed more vertically, avoiding sputum backflow or leakage due to the sputum collection tube 2 being inverted.

[0040] In this embodiment, a cover 5 and a thread 6 are also included. The cover 5 is configured to be detachably connected to the bottom of the sputum collection tube 2. The bottom of the sputum collection tube 2 is sealed by the cover 5. The inner wall of the cover 5 is provided with a thread 6, and the bottom of the sputum collection tube 2 is also provided with a thread 6 at the corresponding position of the cover 5.

[0041] By installing a cover 5 at the bottom of the sputum collection tube 2, sputum can be processed in a timely manner when it is generated inside the sputum collection tube 2, and bacterial growth can be prevented, thus avoiding any impact on the patient.

[0042] In this embodiment, the connecting pipe 1 is also provided with a sealing ring, which can be used to seal the connection between the connecting pipe 1 and the tracheal sleeve. Example 3

[0043] like Figure 6 As shown:

[0044] A tracheostomy tube anti-sputum-spraying device includes a connecting tube 1, a sputum collection tube 2, an air outlet 3, a sputum-blocking plate 4, a cover 5, a thread 6, and an air outlet tube 7. The sputum collection tube 2 is cylindrical and vertically arranged. The connecting tube 1 is located on the side of the sputum collection tube 2. The sputum collection tube 2 is equipped with a trumpet-shaped sputum-blocking plate 4 inside. The air outlet 3 is located at the top of the sputum collection tube 2. The upper part of the sputum-blocking plate 4 has a small opening that connects to the air outlet 3 at the top of the sputum collection tube 2. The bottom of the sputum collection tube 2 is open. The cover 5 seals the bottom of the sputum collection tube 2 through the thread 6. One end of the air outlet tube 7 is located inside the sputum collection tube 2, and the other end extends out of the sputum collection tube 2.

[0045] The sputum-blocking plate 4 has a trumpet-shaped design that is smaller at the top and larger at the bottom, with openings at both the top and bottom. One end of the air outlet pipe 7 is located inside the sputum-blocking plate 4 and enters through the small opening at the top of the sputum-blocking plate 4. The connection is sealed, and the bottom opening of the air outlet pipe 7 is 1.5 cm higher than the bottom opening of the sputum-blocking plate 4.

[0046] The connecting tube 1 is located on the side at one-third of the upper part of the sputum collection tube 2, and the connecting tube 1 is tangential to the sputum collection tube 2. This causes the gas and sputum coughed up by the patient to rotate when they enter the sputum collection tube 2, and move downward along the inner wall of the sputum collection tube 2. During the movement of the gas, the sputum carried inside will adhere to the inner wall of the sputum collection tube 2 due to centrifugal force. When the amount of sputum that has adhered reaches a certain amount, the sputum will flow downward and reach the bottom of the sputum collection tube 2. When a certain amount of sputum has collected at the bottom of the sputum collection tube 2, the cover 5 can be opened to clean the sputum and avoid bacterial contamination.

[0047] By placing the air outlet 3 at the center of the sputum collection tube 2, in practical use, if the sputum collection tube 2 accidentally tipes over, the air outlet 7 will not come into contact with the sputum at the bottom of the sputum collection tube 2. It is only necessary to straighten the sputum collection tube 2 to continue using it, without worrying that the sputum inside the sputum collection tube 2 will pollute the external environment.

[0048] Meanwhile, the vertical upward setting of the exhaust pipe 7 can further prevent sputum from flowing out of the sputum collection tube 2. If some sputum enters the exhaust pipe 7, it will slide down due to gravity when it is absorbed into the exhaust pipe 7. At the same time, during inhalation, the sputum will also be drawn to the bottom of the sputum collection tube 2.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
