Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a sputum suction device for a sputum collection bag. Background Art

[0002] A tracheotomy is a procedure in which an incision is made in the forearm of the cervical trachea, and an appropriately sized endotracheal tube is inserted through the incision, allowing the patient to breathe directly through the tube. A tracheotomy can prevent or quickly relieve airway obstruction, ensuring airway patency, enabling effective ventilation, and improving breathing. However, during postoperative care, patients often cough, causing sputum to splash, contaminating bedsheets and clothing. Furthermore, viruses and bacteria can invade the patient through the tracheotomy. Therefore, caregivers use sputum collection bags to block the endotracheal tube outlet and collect sputum from the patient.

[0003] The sputum collection bag is connected to the endotracheal tube through a sputum suction pump. In this way, the sputum secreted by the patient enters the sputum collection bag from the gas tube through the sputum suction pump. In the prior art, a groove that matches the liquid inlet hole is usually set on the circumferential surface of the sputum suction pump. During installation, the liquid inlet hole is inserted into the groove of the sputum suction pump to achieve the connection between the sputum suction pump and the bag body. However, this method has the following disadvantages: 1. In order to facilitate assembly, the inner diameter of the liquid inlet hole is set larger, so that there is a gap between the groove and the liquid inlet hole. When the patient gets out of bed and moves around, the sputum suction pump is easy to fall off from the bag body. 2. Moreover, because there is a gap between the groove and the liquid inlet hole, the sealing effect is relatively poor, and sputum will seep out through the gap at the connection, contaminating the outside of the sputum collection bag or the surrounding environment.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 2As shown, the present invention is a sputum suction device 20 for a sputum collection bag. It is mounted on the liquid inlet of the sputum collection bag and connected to the airway tube inserted into the patient's trachea, guiding the patient's sputum secretions into the sputum collection bag. The device comprises a lower tube 21 that clamps the edge of the liquid inlet 131 and an upper tube 22. The upper tube 22 is positioned within the sputum collection bag. In this embodiment, both the lower tube 21 and the upper tube 22 are made of antibacterial polypropylene (PP) material.

[0029] Combine Figure 4 and Figure 5 As shown, in this embodiment, the lower tube member 21 is a hollow cylindrical structure with two open ends. The upper tube member 22 consists of a tube portion 221 and an arc-shaped cover 222. An outlet is provided on the side of the cover 222. The arc-shaped cover 222 can stretch the upper fabric of the sputum collection bag, preventing the upper fabric from covering the outlet of the sputum suction device and blocking the patient's sputum from entering the sputum collection bag. At the same time, it can also serve as a drainage function, allowing sputum entering the sputum suction device to smoothly enter the sputum collection bag.

[0030] 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 .

[0031] like Figure 3 、 Figure 4 and Figure 5 As shown, in this embodiment, the clamping structure includes a lower chuck 27 surrounding the upper opening of the lower tube 21, an upwardly protruding protrusion 23 provided on the surface of the lower chuck 27, a protrusion 231 provided on the outer edge of the protrusion 23, and an upper chuck 28 surrounding the lower opening of the upper tube 22. An annular cavity 24 is provided on the lower surface of the upper chuck 28. The inner wall of the cavity 24 has a groove 241 that mates with the protrusion 231.

[0032] like Figure 4 and Figure 5 As shown, in addition, a plurality of protrusions 281 are provided on the upper surface of the lower chuck 27 and the lower surface of the upper chuck 28. With this structure, the edge of the liquid inlet hole can be clamped more tightly.

[0033] The lower pipe 21 has a first limiting structure for limiting the rotation of the upper pipe 22. The upper pipe 22 has a second limiting structure that cooperates with the first limiting structure. In this embodiment, the first limiting structure can be a positioning block 26. The second limiting structure can be a positioning groove 25.

[0034] like Figure 1 As shown, in this embodiment, an oxygen connector 29 is connected to the side of the lower tube 21. This structure allows for direct connection to an oxygen tube for oxygen supply when blood oxygen saturation drops, which is very convenient. Furthermore, a plug 30 is connected to the oxygen connector 29 to seal the oxygen connector's air inlet.

[0035] Combine Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the sputum collection bag comprises an upper fabric 12 and a lower fabric 13. The upper and lower fabrics 12 and 13 are sewn together at their peripheries, forming a retention cavity 15 therein. A liquid inlet 131 is formed in the lower fabric 13, toward the rear edge. The sputum suction device is mounted on the liquid inlet 131.

[0036] like Figure 8 As shown, 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 meltblown fabric 102 positioned between the two layers. The non-woven fabric has excellent stretch resistance and abrasion resistance, and the two-layer design significantly enhances the structural strength of the bag, making it more durable. The meltblown fabric, on the other hand, has high filtration efficiency, barrier properties, and hydrophobicity. Using it as the middle layer effectively blocks the spread of microorganisms such as bacteria and viruses, while also preventing the leakage of sputum or blood.

[0037] like Figure 6 and Figure 8 As shown, multiple vertical pleats 14 are folded in the elongated direction of the upper fabric 12. In this embodiment, there are four pleats 14, with adjacent pleats running parallel to each other. This technical solution increases the internal storage cavity 15 of the bag body during the stretching process of the pleats. Furthermore, the number of pleats can be adjusted as needed to determine the size of the storage cavity 15.

[0038] In this embodiment, the front edge of the sputum collection bag 10 is arc-shaped, and the rear edge is a straight line. Tethers 11 are respectively provided at both ends of the rear edge of the sputum collection bag 10.

[0039] During assembly, first insert the upper tube 22 into the sputum collection bag through the liquid inlet. Next, assemble the lower tube 21 with the upper tube 22. Insert the protruding ring 23 into the concave cavity 24, and insert the positioning block 26 of the lower tube 21 into the positioning groove 25 of the upper tube 22. The two clamps clamp the edges of the liquid inlet 8. The outlet of the upper tube 22 faces the front edge of the sputum collection bag. During use, secure the sputum collection bag to the front of the patient's neck using the tether 11. Then, connect the lower tube 21 of the sputum suction device to the endotracheal tube.

[0040] In summary, the clamping structure can ensure that the upper and lower pipes are firmly clamped on the edge of the liquid inlet of the sputum collection bag, and a good sealing effect is formed. It is also easy to install and disassemble. The sputum collection bag and the tracheal tube are connected together by the suction pump. The cover of the upper pipe stretches the upper fabric of the sputum collection bag to prevent the upper fabric from covering the outlet of the upper pipe and blocking the sputum secreted by the patient from entering the collection bag. At the same time, it can also guide the sputum into the collection bag smoothly. The suction pump is made of antibacterial PP material, which makes the suction pump itself have antibacterial function. By arranging meltblown cloth between the two layers of non-woven fabric, it can effectively block bacteria and viruses and prevent the sputum collected in the collection bag from leaking.

[0041] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
