Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a tracheotomy protection device. Background Art

[0002] At present, after a tracheotomy is performed on a patient in a hospital, the patient breathes directly from the tracheotomy site. When there is sputum in the patient's lungs, it will be ejected directly from the tracheotomy site. Since the ejection of sputum is random and has no directionality, if it is not managed, the sputum will splash randomly, not only polluting the surrounding environment, but also often ejecting onto the medical staff. Therefore, medical staff usually set up a mask with a strap, wrap the patient's neck with the mask, place the tracheotomy tube in the mask, and the mask and the human neck form a closed chamber, so that the sputum is ejected in the closed chamber.

[0003] However, the above device has the following defects: for example, medical staff need to open the cover body before cleaning the sputum, and sputum spraying may still occur during the cleaning process, that is, there is still a risk of cross infection.

[0004] Therefore, a tracheotomy protection device is needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a tracheotomy protection device, so that the sputum inside the sputum shield can be quickly cleaned without opening the sputum shield, so as to effectively avoid cross infection during the sputum treatment process and improve safety.

[0008] The connector is arranged on the bottom wall of the sputum-proof cover and wraps the one-way valve;

[0009] The retractable sac cavity is detachably connected to the connector, and forms a closed chamber around the connector and the bottom wall of the sputum-proof cover;

[0010] When the retractable capsule cavity is compressed, the gas in the closed chamber is discharged through the one-way gas outlet valve;

[0011] When the retractable sac cavity is extended, the gas pulls the one-way valve to deflect in the direction toward the retractable sac cavity, so that the opening is opened, and sputum enters the closed chamber through the opening.

[0012] Furthermore, the connector is provided with external threads on the outside;

[0013] An internal thread matching the external thread is arranged in the telescopic cavity.

[0014] Furthermore, a gas exchange hole is provided on the top of the sputum protection cover, and a filter is provided on the gas exchange hole.

[0015] Further, the sputum-proof cover comprises a lower cover body;

[0016] The one-way valve and the connector are both arranged on the lower cover body;

[0017] The lower cover body is configured as a truncated cone structure, and the outer diameter decreases from top to bottom.

[0018] Furthermore, the opening is configured as an inverted "T"-shaped structure.

[0019] Furthermore, the one-way valve is provided in plurality.

[0020] Furthermore, the one-way valve is configured as a long strip structure.

[0021] Furthermore, a connecting pipe is provided in the middle of the sputum protection cover for connecting with the tracheotomy tube.

[0022] Furthermore, both sides of the sputum protection cover are provided with straps.

[0023] Furthermore, the ends of the two straps are provided with Velcro that are bonded to each other.

[0024] Compared with the prior art, the utility model has at least the following beneficial effects:

[0025] By providing a sputum shield, a one-way valve, a connector with a one-way air outlet valve and a retractable bag cavity, and because the retractable bag cavity can form a closed chamber around the connector and the bottom wall of the sputum shield, when the retractable bag cavity is extended or retracted, the sputum inside the sputum shield can be absorbed with the help of changes in air pressure, that is, the sputum can enter the closed chamber through the opening, thereby achieving rapid cleaning of the sputum inside the sputum shield without opening the sputum shield, effectively avoiding cross infection during the sputum treatment process, and improving safety.

[0031] The tracheotomy protection device of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art may modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the present invention.

[0032] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0033] like Figure 1 to Figure 2 As shown, the embodiment of the utility model provides a tracheotomy protection device, including a sputum protection cover 1, a one-way valve 2, a connector 3 with a one-way air outlet valve, and a telescopic bag cavity 4.

[0034] The bottom of the inner cavity of the sputum protection cover 1 is provided with an opening 5 , and the one-way valve 2 is provided on the opening 5 .

[0035] It should be noted that the one-way valve 2 can only be deflected in a direction away from the sputum protection cover 1 so that the sputum inside the sputum protection cover 1 can flow out.

[0036] The connector 3 is arranged on the bottom wall of the sputum protection cover 1 and wraps the one-way valve 2 .

[0037] In addition, the retractable capsule 4 is detachably connected to the connector 3, and forms a closed chamber around the connector 3 and the bottom wall of the sputum-proof cover 1. When the retractable capsule 4 is compressed, the gas in the closed chamber is discharged by the one-way air outlet valve, that is, the gas is intercepted by the one-way valve 2, so that the gas cannot enter the inside of the sputum-proof cover 1.

[0038] When the telescopic cavity 4 is extended, the gas pulls the one-way valve 2 to deflect in the direction toward the telescopic cavity 4, so that the opening 5 is opened, and sputum enters the closed chamber through the opening 5. That is, when the telescopic cavity 4 is extended, the volume of the closed chamber increases, and correspondingly, its internal pressure decreases. At this time, the internal pressure of the sputum cover 1 is greater than the pressure in the closed chamber, so the gas can enter the closed chamber through the sputum cover 1, causing the one-way valve 2 to deflect and then open the opening 5. Therefore, the sputum can enter the closed chamber along the opening 5 to complete the sputum cleaning.

[0039] Therefore, the device is provided with a sputum-proof cover 1, a one-way valve 2, a connector 3 with a one-way air outlet valve and a retractable bag cavity 4. Since the retractable bag cavity 4 can form a closed chamber around the connector 3 and the bottom wall of the sputum-proof cover 1, when the retractable bag cavity 4 is retracted, it can absorb the sputum inside the sputum-proof cover 1 with the help of changes in air pressure, that is, the sputum can enter the closed chamber through the opening 5, so that the sputum inside the sputum-proof cover 1 can be quickly cleaned without opening the sputum-proof cover 1, effectively avoiding cross infection during the sputum treatment process, thereby improving safety.

[0040] In this embodiment, in order to facilitate the replacement and cleaning of the telescopic capsule cavity 4, an external thread is provided on the outside of the connecting head 3, and an internal thread matching the external thread is provided inside the telescopic capsule cavity 4 to complete the detachable connection between the telescopic capsule cavity 4 and the connecting head 3.

[0041] In addition, a gas exchange hole 6 is provided on the top of the anti-sputum cover 1, and a filter is provided on the gas exchange hole 6 to provide a source of breathing gas for the patient.

[0042] In other embodiments, the sputum-proof cover 1 is further limited so that the sputum is better gathered on the bottom wall of the sputum-proof cover 1. Specifically, the sputum-proof cover 1 includes a lower cover body 11, the one-way valve 2 and the connector 3 are both arranged on the lower cover body 11, and the lower cover body 11 is arranged as a truncated cone structure, and the outer diameter decreases from top to bottom, that is, the outer wall of the lower cover body 11 is an inclined surface to accelerate the falling of sputum and prepare for subsequent cleaning.

[0043] In this embodiment, the opening 5 is configured as an inverted "T"-shaped structure so that the one-way valve 2 can only deflect in one direction.

[0044] Preferably, a plurality of one-way valves 2 are provided. Furthermore, the one-way valve 2 is provided as a long strip structure to cooperate with the shape of the opening 5 to realize the one-way opening function.

[0045] In a further embodiment, in order to facilitate the protection of the tracheotomy tube, a connecting tube 7 is provided in the middle of the sputum protection cover 1 for connecting with the tracheotomy tube and also for wrapping the tracheotomy tube.

[0046] In other embodiments, the two sides of the sputum protection cover 1 are provided with straps 8. The ends of the two straps 8 are provided with Velcro 81 that are bonded to each other.

[0047] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
