Description

Technical area

[0001] The present utility model relates to the field of medical devices, in particular a tracheostomy protective hood. State of the art

[0002] Tracheostomy is an emergency technique used to rescue critically ill patients and can improve breathing problems after surgery for various reasons. During this operation, the anterior wall of the cervical trachea is opened, and an appropriately sized tracheostomy tube is inserted through the opening into the trachea, allowing the patient to breathe directly through the tracheostomy tube. The goals of tracheostomy are to prevent or quickly relieve airway obstruction, ensure airway clearance, provide effective ventilation, and improve breathing. During postoperative care, patients often tend to cough up sputum, which contaminates bedsheets and clothing and puts the skin in the throat area at risk for infection. Viruses and bacteria can enter the patient through the tracheostomy opening.Furthermore, sputum splashing increases the risk of body fluid exposure for healthcare workers and family caregivers and can cause cross-infection among patients in the same hospital room through aerosol transmission. Viruses and bacteria can expose individuals entering the hospital room to a high-risk environment. Therefore, there is a potential for cross-infection and discomfort in care activities for physicians, nurses, and patients.

[0003] Chinese Patent Publication 202020219199.8 discloses a new type of respiratory protective hood comprising a bag and fastening cords attached to both ends of the bag. The bag consists of a front protective surface and a rear protective surface sewn together to form a hollow space with a drainage opening. When in use, it forms a bag-like structure with a hollow space that can be securely attached to the neck area using the fastening cords. It can effectively collect sputum and prevent splashing, preventing clothing from being wetted, and effectively shield the tracheostomy opening to prevent viral penetration. However, when patients breathe, the collision of the front and rear protective surfaces leads to increased breathing resistance, hindering the patient's breathing.In addition, this leads to the sputum excreted by the patient accumulating at the fluid inlet of the bag and making it difficult to drain into the bag interior, which reduces collection efficiency. Content of the utility model

[0004] Based on this and in view of the above technical problems, the present utility model provides a tracheostomy protective hood.

[0005] The purpose of this utility model can be realized by the following technical solutions.

[0006] A tracheostomy hood includes a bag and tie cords positioned at both ends of the rear edge of the bag. The bag includes an upper fabric panel and a lower fabric panel, the edges of the upper fabric panel and the lower fabric panel being sewn together to form a cavity inside. The hood further includes a sputum suction device. A fluid inlet port is provided at a position near the rear edge of the lower fabric panel. The sputum suction device is mounted on the fluid inlet port. The sputum suction device includes a lower tube and an upper tube that clamp the edge of the fluid inlet port. The upper tube is located inside the bag. A lid of the upper tube spreads open the upper fabric panel. An outlet is provided on the side of the lid and faces the front edge of the bag.

[0007] By applying the above-mentioned technical solution, the upper fabric part of the bag is spread open by the lid of the upper tube. The lid has an outlet on its side facing the front edge of the bag. This prevents the upper fabric part from covering the outlet of the sputum suction device and blocking sputum from entering the bag.

[0009] In the specific embodiment of the present utility model, the upper end of the lower tube section and the lower end of the upper tube section have a clamping device. The clamping device comprises a lower clamping disc surrounding the upper opening of the lower tube section, an annular projection projecting upwardly on the surface of the lower clamping disc, a projection on the outer edge of the mouth of the annular projection, and an upper clamping disc surrounding the lower opening of the upper tube section. The lower surface of the upper clamping disc has an annular recess, and the inner wall of the recess has a groove that cooperates with the projection.

[0010] In the specific embodiment of the present utility model, both the upper surface of the lower clamping disc and the lower surface of the upper clamping disc have a plurality of dimples. By adopting this structure, the edge of the fluid inlet opening can be clamped more firmly.

[0011] In the specific embodiment of the present utility model, the lower tube piece has a first limiting device for limiting the rotation of the upper tube piece, and the upper tube piece has a second limiting device which cooperates with the first limiting device.

[0012] In the specific embodiment of the present utility model, the first limiting means is a positioning block, and the second limiting means is a positioning groove.

[0013] In the specific embodiment of the present utility model, an oxygen connection is connected to the side of the lower pipe section.

[0014] In the specific embodiment of the present utility model, both the upper fabric part and the lower fabric part consist of two layers of nonwoven fabric and a meltblown nonwoven fabric arranged between the two nonwoven fabric layers.

[0015] In the specific embodiment of the present utility model, the edges of the upper fabric part and the lower fabric part are pressed together by hot melting.

[0016] In the specific embodiment of the present utility model, the front edge of the bag is circular in shape and the rear edge is straight.

[0017] In the specific embodiment of the present utility model, several vertical strip-shaped folds are folded lengthwise on the upper part of the fabric.

[0018] In summary, in this utility model, the upper fabric part of the bag is spread open by the lid of the sputum suction device to prevent the upper fabric part from covering the outlet of the sputum suction device and preventing the patient's sputum from entering the bag. At the same time, the sputum can be guided to smoothly enter the bag. By placing a meltblown nonwoven fabric between the two nonwoven fabric layers, bacteria and viruses can be effectively contained and the sputum collected in the bag can be prevented from seeping out.

Examples of implementation

[0020] In the following, the technical solutions in the embodiments of the present utility model are described clearly and completely with reference to the figures in the embodiments of the present utility model. Obviously, the described embodiments represent only a part of the embodiments of the present utility model and not the entire embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by a person skilled in the art without creative effort fall within the scope of protection of the present utility model.

[0021] As in Fig. 1 and Fig. As shown in Figure 5, the present utility model is a tracheostomy protective hood. The protective hood comprises a bag 10 and fixation cords 11 arranged at both ends of the rear edge of the bag 10. The bag 10 comprises an upper fabric part 12 and a lower fabric part 13. The edges of the upper fabric part 12 and the lower fabric part 13 are sewn together, thereby forming a cavity 15 inside.

[0022] As in Fig. 3 and Fig. 4, the edges of the upper fabric part 12 and the lower fabric part 13 are pressed together by hot melting in this embodiment.

[0023] As in Fig. As shown in Figure 5, both the upper fabric part 12 and the lower fabric part 13 consist of two layers of nonwoven fabric 101 and, in this embodiment, a meltblown nonwoven fabric 102 arranged between the two nonwoven fabric layers 101. The nonwoven fabrics exhibit good tensile strength and abrasion resistance. The design with two nonwoven layers significantly increases the structural strength of the bag and makes it more durable. The meltblown nonwoven fabric, on the other hand, is characterized by high filter efficiency, barrier properties, and hydrophobicity. As a middle layer, the meltblown nonwoven fabric effectively prevents the transmission of bacteria, viruses, and other microorganisms while simultaneously preventing the leakage of sputum or blood.

[0024] As in Fig. 3 and Fig. As shown in Figure 5, a plurality of vertical strip-shaped pleats 14 are folded longitudinally on the upper fabric part 12. In this embodiment, the number of pleats is 144, and adjacent pleats are parallel to each other. With the above technical solution, the internal cavity 15 of the bag body is enlarged upon expansion of the folded pleats. Furthermore, the size of the cavity 15 can be determined as needed by adjusting the number of folded pleats.

[0025] In this embodiment, the front edge of the bag 10 is circular and the rear edge is straight.

[0026] As in Fig. 1, Fig. 2, and Fig. As shown in Figure 6, the protective hood further includes a sputum suction device 20. A liquid inlet opening 131 is provided at a position near the rear edge of the lower fabric part 13. The sputum suction device 20 is mounted on the liquid inlet opening 131.

[0027] The sputum suction device 20 comprises a lower tube section 21 and an upper tube section 22, which clamp the edge of the liquid inlet opening 131. The upper tube section 22 is located inside the bag.

[0028] As in Fig. 8 and Fig. As shown in Figure 9, the lower tube 21 is a hollow cylindrical structure with open ends, and the upper tube 22 includes a tube portion 221 and the circular-arc-shaped lid 222 in this embodiment. An outlet is provided on the side of the lid 222. The circular-arc-shaped lid 222 spreads the upper fabric portion to prevent the upper fabric portion from covering the outlet of the sputum suction device and blocking the introduction of patient sputum into the cavity. At the same time, it effectively guides the sputum entering the sputum suction device into the cavity. In this embodiment, the lower tube 21 and the upper tube 22 are made of antibacterial PP material.

[0029] The upper end of the lower pipe section 21 and the lower end of the upper pipe section 22 have a clamping device.

[0030] As in Fig. 6, Fig. 7, Fig. 8, and Fig. 9, the clamping device comprises a lower clamping disc 27 surrounding the upper opening of the lower tube piece 21, an annular projection 23 projecting upwards on the surface of the lower clamping disc 27, a projection 231 on the outer edge of the mouth of the annular projection 23, an upper clamping disc 28 surrounding the lower opening of the upper tube piece 22, the lower surface of the upper clamping disc 28 having an annular recess 24, and the inner wall of the recess 24 having a groove 241 which cooperates with the projection 231.

[0031] As in Fig. 8 and Fig. As shown in Fig. 9, both the upper surface of the lower clamping disc 27 and the lower surface of the upper clamping disc 28 have a plurality of nubs 281. By adopting this structure, the edge of the liquid inlet port can be clamped more firmly.

[0032] The lower tube section 21 has a first limiting device for limiting the rotation of the upper tube section 22, and the upper tube section 22 has a second limiting device that cooperates with the first limiting device. In this embodiment, the first limiting device is a positioning block 26, and the second limiting device is a positioning groove 25.

[0033] As in Fig. As shown in Figure 6, an oxygen port 29 is connected to the side of the lower pipe section 21 in this embodiment. With this structure, an oxygen hose can be directly connected to supply oxygen when the oxygen saturation drops, which is very convenient. Additionally, a plug 30 is attached to the oxygen port 29, which closes the inlet opening of the oxygen port 29.

[0034] During assembly, the upper tube section 22 is first inserted into the bag through the fluid inlet opening. Then, the lower tube section 21 and the upper tube section 22 are assembled, the annular projection 23 is inserted into the recess 24, and the positioning block 26 of the lower tube section 21 is inserted into the positioning groove 25 of the upper tube section 22. Both clamping discs clamp the edge of the fluid inlet opening 8. The outlet of the upper tube section 22 is aligned with the front edge of the bag 10. During use, the bag 10 is attached to the front of the patient's neck using the fixation cords 11. The lower tube section 21 of the sputum suction device is then connected to the tracheostomy tube.

[0035] In summary, in this utility model, the upper fabric part of the bag is spread open by the lid of the sputum suction device to prevent the upper fabric part from covering the outlet of the sputum suction device and preventing the patient's sputum from entering the bag. At the same time, the sputum can be guided to smoothly enter the bag. By placing a meltblown nonwoven fabric between the two nonwoven fabric layers, bacteria and viruses can be effectively contained and the sputum collected in the bag can be prevented from seeping out.
