[0027] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See also Figure 1 and Figure 2 The utility model discloses a sputum collection device for bedridden patients, which is used for expectorating and collecting sputum for bedridden infectious disease patients when the patients have removed their masks.

[0031] A sputum collection device for bedridden patients comprises a mask 1, a sputum guide tube 2 and a collection bag 3. The mask 1 at least covers the patient's mouth, one end of the sputum guide tube 2 penetrates into the mask 1 and extends into the patient's oral cavity, and the other end of the sputum guide tube 2 is connected to the collection bag 3.

[0032] When the patient lies down, insert the sputum catheter into the mask and align it with the patient's mouth, and extend the inner end of the sputum catheter into the patient's mouth. The sputum in the patient's mouth can be directly discharged through the sputum catheter and collected in a collection bag.

[0033] During the sputum collection process, the patient does not need to remove the mask, and the patient's sputum, saliva, etc. will not splash into the environment, ensuring the cleanliness and hygiene of the surrounding environment. For some patients with infectious diseases, this method of expectoration and sputum collection can reduce the risk of infection caused by medical staff or accompanying personnel in the surrounding environment.

[0034] The mask is not removed while sputum is discharged and collected, and the oxygen supply device connected to the mask can work normally to deliver oxygen to the patient, ensuring the patient's normal treatment or maintenance of vital signs.

[0035] During the expectoration operation, the operator basically does not need to come into contact with the patient's sputum or saliva, reducing the risk of infection caused by medical staff or accompanying personnel.

[0036] In addition, the sputum collection device can perform continuous expectoration and sputum collection for a long time, which can avoid repeated expectoration operations in a short period of time and reduce the workload of medical staff or accompanying personnel.

[0037] The sputum collection device can realize active sputum discharge when expectorating, that is, the patient actively spits the sputum in the oral cavity into the sputum guide tube 2, and the sputum is transported to the collection bag through the sputum guide tube 2.

[0038] like Figure 1 As shown, a peristaltic pump 10 is arranged on the sputum catheter 2. When the peristaltic pump works, a vacuum is generated in the sputum catheter 2. The vacuum in the sputum catheter 2 can make the sputum in the oral cavity actively flow into the collection bag, thereby realizing passive expectoration for bedridden patients. Especially for some patients who have difficulty expectorating or sputum in the throat that is difficult to cough up, the vacuum suction in the sputum catheter generated by the peristaltic pump can help discharge the sputum in the patient's mouth or even in the throat that is difficult to cough up, thereby reducing the difficulty of expectoration for the patient.

[0039] Based on the above scheme, by using the sputum collection device, mechanical active expectoration operation is realized, and the patient passively expectorates, which also avoids the patient using a slapping type expectoration device or using atomized drugs to expectorate for a long time.

[0040] like Figure 1 As shown, a through hole is provided on the mask 1, a connecting end 5 is fixedly provided on the outer surface of the mask 1, the connecting end 5 is communicated with the through hole, the sputum guiding tube 2 passes through the connecting end 5 and the through hole, and extends into the mask 1.

[0041] By setting a through-hole and a connecting end, a detachable connection between the sputum catheter and the mask is achieved, and the sputum catheter 2 can be replaced regularly or periodically to ensure the patient's hygienic condition.

[0042] like Figure 1 As shown, a valve plate 7 is arranged in the connecting end 5. When the sputum guiding tube 2 is withdrawn from the connecting end 5, the valve plate 7 cuts off the passage of the connecting end 5. A sealing plug 8 is arranged at the end of the connecting end 5 away from the mask 1.

[0043] By setting a valve sheet, when the sputum catheter is withdrawn from the connection end, the valve sheet can close the channel of the connection end to prevent the patient's breathing gas from being discharged from the mask through the channel of the connection end. Especially for some patients with infectious diseases, the setting of the valve sheet reduces the risk of infection of medical staff or accompanying personnel in the surrounding environment. A sealing plug is set to further completely close and cut off the channel of the connection end. The sealing plug is used when the sputum catheter is temporarily not needed to be connected, further ensuring the closure of the channel of the connection end and the mask, and preventing the patient's breathing gas from overflowing through the channel of the connection end and causing infection to the surrounding environment.

[0044] In order to ensure the smooth entry and exit of the sputum catheter, it is also convenient for the valve plate to close the channel of the connecting end when the sputum catheter is withdrawn from the connecting end, or further, when the sputum catheter leaves the valve plate, the valve plate can close the channel of the connecting end. Here, the shape of the cross section of the valve plate and the connecting end is consistent, which is circular. Figure 3 As shown, the valve plate 7 is formed by a plurality of flexible movable plates 71, and two adjacent movable plates are close to and in contact with each other. When the sputum catheter is passed into the connecting end, the movable plate is pushed to rotate toward the inner wall side of the connecting end, so that the sputum catheter can pass through the valve plate. When the sputum catheter is withdrawn from the valve plate, the movable plate will be reset to achieve blocking of the channel of the connecting end.

[0045] When the valve plate is removed from the sputum catheter, the movable plate will be reset to block the channel of the connecting end, avoiding the gap between the two adjacent movable plates, which will affect the blocking of the connecting end. Figure 4As shown, on the valve plate 7, there is a certain overlap between two adjacent movable plates 71, so that there will be no gap between the two adjacent movable plates 71, which can ensure that the channel of the connecting end is well blocked.

[0046] like Figure 1 As shown, a sputum suction cotton block 6 is arranged in the connecting end 5. The sputum suction cotton block 6 is tubular and fixed between the valve plate 7 and the outer surface of the mask 1. The inner diameter of the sputum suction cotton is adapted to the outer diameter of the sputum guiding tube 2.

[0047] The sputum suction cotton block 6 is provided to, on the one hand, prevent the water vapor generated by the patient's breathing in the mask from overflowing from the connecting end, and absorb the water vapor entering the connecting end in the mask; on the other hand, in the process of the sputum catheter being pulled out of the connecting end, the sputum or saliva on the outer wall of the sputum catheter is absorbed to prevent the sputum or saliva on the outer wall of the sputum catheter from overflowing from the connecting end, and to prevent the sputum or saliva from dripping into the environment to cause secondary pollution.

[0048] like Figure 1 As shown, the sputum guide tube 2 includes a first section and a second section connected in sequence, the first section and the second section are detachably connected, the end of the first section away from the second section extends into the mask 1, and the end of the second section away from the first section is connected to the collection bag 3.

[0049] The sputum guide tube is arranged into a first section and a second section, so that the first section can be replaced separately, that is, the first section of the sputum guide tube can be replaced without replacing the collection bag, and the first section extends into the mask, that is, the first section that is in direct contact with the patient's mouth is replaced, so that the patient maintains a good hygienic state. In addition, only the first section is replaced, and the collection bag is used for multiple sputum suction, which reduces costs.

[0050] like Figure 1 As shown, the end of the second section near the first section is provided with a first connecting sleeve 9, the first section is detachably connected to the first connecting sleeve 9, and the second section is fixedly connected to the first connecting sleeve 9. By providing the first connecting sleeve, the replacement operation of the first section is simplified, and the reliable connection between the first section and the second section is also ensured.

[0051] like Figure 1 As shown, a second connecting sleeve 11 is fixed to the end of the sputum guiding tube 2 away from the mask 1, and the collecting bag 3 is detachably connected to the second connecting sleeve 11.

[0052] The first connecting sleeve is provided so that the collection bag can be removed separately to realize the replacement of the collection bag. Of course, when removing the collection bag, the peristaltic pump should be turned off, or the sputum guide tube should be placed at the inner end of the mask away from the patient's mouth to avoid expectoration when replacing the collection bag. Of course, further, when replacing the collection bag, the patient is prevented from expectorating, and the patient's breathing gas is prevented from being output through the sputum guide tube. A stop valve is provided on the sputum guide tube, and when replacing the collection bag, the stop valve is closed to further reduce the risk of infection to the surrounding environment or personnel.

[0053] exist Figure 1 Based on the technical solution in this paper, in order to ensure that patients can expectorate continuously, such as Figure 2 As shown, the sputum guiding tube 2 is provided with a first branch pipe and a second branch pipe near the end of the collecting bag 3, and the first branch pipe and the second branch pipe are respectively detachably connected with the collecting bag 3, and the first branch pipe and the second branch pipe are respectively provided with a stop valve. That is, two collecting bags 3 are provided, so that when one collecting bag is replaced, the other collecting bag continues to collect sputum.

[0054] In this solution, sputum is collected into a collection bag, and then the collection bag is centrally collected and processed to avoid multiple transfers of sputum and reduce the risk of infection. In addition, a volume scale is set on the collection bag to display the amount of collected sputum, avoiding testing of patients and taking appropriate treatment measures.

[0055] In the present technical solution, the mask 1 covers the patient's mouth and nose, and is also connected to an oxygen airway tube 4, which is also provided with a leak valve 41, and a waste gas recovery pipe is connected to the leak valve 41. The oxygen airway tube 4 delivers oxygen or oxygen-containing gas into the mask to supply oxygen to the patient, and the waste gas exhaled by the patient is discharged through the leak valve and recovered through the waste gas recovery pipe to avoid direct discharge of the waste gas into the surrounding environment, causing pollution to the surrounding environment or infection of surrounding personnel.

[0056] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
