Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical devices, and specifically to a tracheotomy protection cover.
Background Art
[0002] Tracheotomy is a technique for emergency treatment of critically ill patients, and it can improve breathing difficulties caused by various reasons after the operation. This is an operation in which the anterior wall of the cervical trachea is incised, a tracheal tube of an appropriate size is inserted through the incision, and the patient can breathe directly through the tracheal tube. The purpose of tracheotomy is to prevent or quickly relieve airway obstruction, ensure the airway, guarantee effective ventilation, and improve breathing. In the postoperative care process, the patient's sputum scatters due to coughing, contaminating bedding and clothing, and the cervical skin is prone to infection, and viruses and bacteria may enter the patient's body from the tracheotomy site. Furthermore, the scattering of sputum increases the risk of body fluid exposure for medical staff and caregivers, causes cross-infection to other patients in the same room due to aerosol infection, and viruses and pathogens expose the people in the ward to a high-risk environment. Therefore, it brings the possibility of cross-infection and the inconvenience of care activities to medical staff, caregivers, and patients.
[0003] Chinese Patent No. 202020219199.8 discloses a new tracheotomy tube protection cover, which includes a bag body and fixing straps provided at both ends thereof. The bag body includes a front protection surface and a rear protection surface, and the front protection surface and the rear protection surface are stitched to form a cavity leaving an excretion port. In the use state, it becomes a pocket-shaped structure with a cavity, and the protection cover can be appropriately fixed to the area in front of the neck with the fixing straps, which is effective for receiving sputum, preventing its scattering, preventing clothing contamination caused by sputum scattering, shielding the tracheotomy site, and defending against virus invasion. However, when the patient breathes, the front protection surface and the rear protection surface are in close contact, increasing the breathing resistance, which makes the patient's breathing uncomfortable. At the same time, the sputum secreted by the patient stays at the entrance of the bag, preventing its inflow into the bag, and therefore, there is a problem of reduced collection efficiency.

Embodiments for Carrying Out the Invention
[0021] Next, based on the drawings in the embodiments of the present invention, the technical solution means in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention and do not cover all embodiments. All other embodiments obtained by those skilled in the art without creative labor based on the embodiments in the present invention belong to the protection scope of the present invention.
[0022] As shown in Figures 1 and 5, the present invention is a tracheotomy protection cover, which includes a bag body 10 and locking strings 11 provided at both ends of the trailing edge of the bag body 10. The bag body includes an upper fabric 12 and a lower fabric 13. The upper fabric 12 and the lower fabric 13 have their peripheries sewn together to form a storage cavity 15 inside.
[0023] As shown in Figures 3 and 4, in this embodiment, the peripheries of the upper fabric 12 and the lower fabric 13 are pressed together by heat sealing.
[0024] As shown in Fig. 5, in this embodiment, both the upper fabric 12 and the lower fabric 13 are composed of two layers of non-woven fabric 101 and a melt-blown non-woven fabric 102 provided in the middle of the two layers of non-woven fabric 101. Here, the non-woven fabric has excellent tensile strength and abrasion resistance, and the design of the two-layer non-woven fabric greatly enhances the structural strength of the bag body and improves durability. On the other hand, the melt-blown non-woven fabric has high filtration efficiency, blocking performance, and hydrophobic performance. By using the melt-blown non-woven fabric as the middle layer, the transmission of microorganisms such as bacteria and viruses can be effectively blocked, and at the same time, the seepage of sputum and blood can be avoided.
[0025] As shown in Figs. 3 and 5, a plurality of longitudinal pleats 14 are folded along the length direction of the upper fabric 12. In this embodiment, the number of pleats 14 is four, and the adjacent pleats are parallel to each other. By adopting the above technical solution, during the process of stretching the folded pleats, the storage cavity 15 inside the bag body is enlarged. Furthermore, the number of folded pleats can be adjusted as needed to determine the size of the storage cavity 15.
[0026] In this embodiment, the front edge of the bag body 10 is arc-shaped, and the rear edge is straight.
[0027] As shown in Figs. 1, 2, and 6, a sputum aspirator 20 is further included. An inflow hole 131 is opened at a position near the rear edge of the lower fabric 13. The sputum aspirator 20 is attached to the inflow hole 131. The sputum aspirator 20 is composed of a lower tube member 21 and an upper tube member 22 that sandwich the edge of the inflow hole 131. The upper tube member 22 is disposed inside the bag body.
[0028] As shown in FIGS. 8 and 9, in this embodiment, the lower pipe member 21 has a hollow cylindrical structure with openings at both ends. The upper pipe member 22 consists of a pipe portion 221 and an arc-shaped hood 222. An outlet is provided on the side of the hood 222. The arc-shaped hood 222 spreads the upper fabric, and by covering the outlet of the sputum aspirator with the upper fabric, it avoids preventing the patient's sputum from flowing into the storage cavity. At the same time, it exerts a guiding effect, and the sputum flowing into the sputum aspirator is smoothly guided into the storage cavity. In this embodiment, both the lower pipe member 21 and the upper pipe member 22 are made of antibacterial pp material.
[0029] A clamping structure is provided at the upper end of the lower pipe member 21 and the lower end of the upper pipe member 22.
[0030] As shown in FIGS. 6, 7, 8 and 9, in this embodiment, the clamping structure includes a lower clamping plate 27 surrounding the opening on the upper side of the lower pipe member 21, a convex ring 23 protruding upward on the surface of the lower clamping plate 27, a protrusion 231 provided at the outer edge of the opening of the convex ring 23, and an upper clamping plate 28 surrounding the opening on the lower side of the upper pipe member 22. A ring-shaped recess 24 is provided on the lower surface of the upper clamping plate 28. A concave groove 241 fitted with the protrusion 231 is provided on the inner wall of the recess 24.
[0031] As shown in FIGS. 8 and 9, further, a plurality of convex points 281 are provided on both the upper surface of the lower clamping plate 27 and the lower surface of the upper clamping plate 28. By adopting this structure, the edge of the inflow hole can be clamped more firmly.
[0032] A first restricting structure for restricting the rotation of the upper pipe member 22 is provided on the lower pipe member 21. A second restricting structure cooperating with the first restricting structure is provided on the upper pipe member 22. In this embodiment, the first restricting structure may be the positioning block 26. The second restricting structure may be the positioning groove 25.
[0033] As shown in FIG. 6, in this embodiment, an oxygen connection port 29 is connected to the side of the lower tube member 21. By adopting this structure, when the blood oxygen saturation decreases, an oxygen tube can be directly connected to supply oxygen, which is very convenient. Further, a plug 30 for sealing the air inlet of the oxygen connection port 29 is connected to the oxygen connection port 29.
[0034] During assembly, first insert the upper tube member 22 into the bag body through the inflow hole. Then, combine the lower tube member 21 with the upper tube member 22, insert the convex ring 23 into the concave portion 24, insert the positioning block 26 of the lower tube member 21 into the positioning groove 25 of the upper tube member 22, and the two clamping discs sandwich the edge of the inflow hole 8. Also, the outlet of the upper tube member 22 faces the front edge of the bag body 10. When in use, fix the bag body 10 in the range of the front of the patient's neck with the locking string 11, and then connect the lower tube member 21 of the sputum aspirator to the tracheal tube.
[0035] As described above, with the hood of the sputum aspirator of the present invention, the upper fabric of the bag body is spread, and by covering the outlet of the sputum aspirator with the upper fabric, it is avoided that the patient's sputum enters the bag body, and at the same time, it conducts the inflow of sputum into the bag body. By installing a meltblown non-woven fabric between the two layers of non-woven fabrics, bacteria and viruses can be effectively blocked, and at the same time, it is possible to avoid the leakage of the sputum collected in the bag body.
[0036] As described above, one embodiment of the present invention has been described in detail. However, the content described here is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
