[0002] Sputum suction is a medical operation, mainly used to help patients who cannot effectively clear respiratory secretions (such as sputum) by themselves. Sputum suction is very common in medical settings, especially for patients with respiratory diseases, coma, postoperative patients, and patients whose cough reflex is weakened or disappeared due to various reasons. Sputum suction is crucial for maintaining the patency of the patient's airway, but it also carries certain risks, such as possible damage to the respiratory mucosa, infection, etc.; therefore, when performing sputum suction operation, medical staff must strictly follow aseptic operation specifications and closely observe the patient's reaction and condition.

[0003] Negative pressure sputum suction is a commonly used technique in clinical practice. Negative pressure sputum suction utilizes the principle of atmospheric pressure to generate negative pressure through a negative pressure machine, which sucks the sputum and secretions in the patient's respiratory tract into the sputum suction tube and then into the sputum bucket, ensuring the cleanliness and patency of the respiratory tract. When performing negative pressure sputum suction, the choice of pressure is crucial, as too low a pressure may not effectively remove sputum and clear obstructions, while too high a pressure may stimulate airway spasm and cause airway damage; therefore, the appropriate pressure must be selected based on the patient's specific condition during negative pressure sputum suction. The sputum bucket includes an outer bucket and an inner bag placed inside the outer bucket to collect sputum. The problem now is that when the negative pressure machine is started for sputum suction, the inner bag will be sucked flat due to the negative pressure effect, causing the sputum sucked out at the beginning to not flow smoothly into the bottom of the inner bag, but instead to easily overflow from the sealing port or connecting pipe and further flow into the inner part of the outer bucket; only when the accumulated sputum reaches a certain amount, will the inner bag unfold due to the gravity of the sputum, allowing the sputum to flow down smoothly; after the inner bag is filled with sputum, medical staff need to remove and discard it, as a portion of the sputum often flows into the outer bucket, to avoid infection caused by virus transmission, the outer bucket must also be thoroughly cleaned and disinfected after discarding the inner bag; however, the outer bucket is large in volume and the sputum is highly viscous, making it very inconvenient to clean and disinfect, and medical staff are mostly unwilling to accept the task of cleaning the outer bucket; in addition, for patients who only need a small amount of sputum suction or one-time sputum suction (or suction of other secretions in the cavity), such a large sputum bucket is also relatively cumbersome to use.

[0031] The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments. Example

[0032] This embodiment provides a convenient sputum collection device, such as... Figures 1-3 As shown, it includes: a negative pressure connector 1, a drainage tube 2, and a collection bag 3; wherein, the negative pressure connector 1 has a hollow inner cavity, and a first connecting tube 11 and a second connecting tube 12 communicating with the hollow inner cavity, the first connecting tube 11 being adapted to connect with a negative pressure tube; the drainage tube is fixedly disposed in the negative pressure connector 1, with a connecting end 21 extending out of the negative pressure connector 1, and an outlet end 22 extending outward from the second connecting tube 12 through the hollow inner cavity; the connecting end 21 is adapted to connect with a suction tube, and there is a gap between the outer wall of the drainage tube 2 and the inner wall of the second connecting tube 12; the collection bag 3 is made of soft material, has an internal accommodating space, and can be fixedly connected to the second connecting tube 12, and after the collection bag 3 is connected to the second connecting tube 12, the outlet end 22 extends into the internal accommodating space of the collection bag 3.

[0033] When used for suctioning patients, connect the negative pressure tube to the first connecting tube 11 and the suction tube to the connecting end 21. During suctioning, sputum flows through the drainage tube 2 into the collection bag 3. Initially, the collection bag 3 is compressed by the negative pressure, and the sputum cannot flow directly into the inside of the collection bag 3, but will temporarily accumulate in the folded area of ​​the collection bag 3. Under the suction of the negative pressure machine, the sputum is drawn upward and temporarily stored in the hollow inner cavity of the negative pressure connector 1. When the sputum gradually accumulates to a certain amount in the hollow inner cavity, the collection bag 3 is gradually opened by the downward pressure of the sputum, and the sputum temporarily stored in the hollow inner cavity will flow downward into the collection bag 3. For patients who only need a small amount of sputum suction, medical staff can hold the suction device to suction during operation. After the sputum is suctioned, the suction device can be disposed of in accordance with medical waste disposal regulations.

[0034] This embodiment of a convenient sputum collection device prevents sputum leakage during suctioning, ensuring hygiene and safety. It eliminates the need for tedious cleaning and disinfection after use, saving medical staff time and effort and improving work efficiency. Furthermore, this device is particularly suitable for patients requiring only small amounts of suctioning, enhancing the targeted nature of treatment.

[0035] The portable sputum collection device in this embodiment is made of plastic and is a disposable item that can be discarded after use.

[0036] like Figure 3 As shown, the outlet end 22 is funnel-shaped. This design of the outlet end 22 helps to open the collection bag 3, allowing sputum to enter the deflated collection bag 3 more easily.

[0037] The liquid outlet end 22 is uniformly provided with a plurality of long strip openings 23. During sputum suction, sputum may accumulate and stay due to viscosity at the liquid outlet end. The long strip openings 23 can enhance the flowability to a certain extent.

[0038] The negative pressure connecting piece 1 is fixedly provided with at least one hook 4. During continuous sputum suction for a patient, the sputum suction device can be hooked on a hospital bed or an infusion rod through the hook 4, so that medical staff can more conveniently perform sputum suction operation.

[0039] The negative pressure connecting piece 1 is provided with a connecting through hole communicating with the hollow inner cavity. The connecting end 21 extends from the connecting through hole and is fixedly arranged at the position of the connecting through hole. The connecting end 21 extends from the connecting through hole, and glue is applied at the contact position between the connecting end 21 and the connecting through hole. The connecting end 21 and the connecting through hole are firmly fixed by the adhesion of the glue.

[0040] The collection bag 3 comprises a main body part 31 and a connecting part 32 integrally formed at the opening position of the main body part 31. The inner wall of the connecting part 32 is provided with internal threads, the outer wall of the second connecting pipe 12 is provided with external threads, and the connecting part 32 is threadedly connected with the second connecting pipe 12, so as to screw the negative pressure connecting piece 1 with the collection bag 3. The threaded connection between the connecting part 32 and the second connecting pipe 12 improves the stability and sealing performance of the connection, effectively prevents sputum from overflowing, and enables medical staff to quickly and accurately complete the connection, thereby improving work efficiency.

[0041] The first connecting pipe 11 is adapted to be inserted or screwed with the negative pressure pipe, and the connecting end 21 is adapted to be inserted or screwed with the sputum suction pipe. Taking screwing as an example, external threads are arranged on the outer wall of the first connecting pipe 11, and internal threads are arranged on the inner wall of the negative pressure pipe. The first connecting pipe 11 is screwed with the negative pressure pipe. External threads are arranged on the outer wall of the connecting end 21, and internal threads are arranged on the inner wall of the sputum suction pipe. The connecting end 21 is screwed with the sputum suction pipe.

[0042] The drainage pipe 2 is made of hard material, and the outer diameter of the liquid outlet end 22 is smaller than the inner diameter of the second connecting pipe 12. The drainage pipe 2 is made of hard material, which can ensure that the drainage pipe 2 still maintains its original shape and smoothness when the collection bag 3 is sucked by the negative pressure, thereby effectively ensuring the smooth flow of sputum.

[0043] Obviously, the above embodiments are only examples for clearly illustrating the application, and are not intended to limit the application. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or modifications derived therefrom are still within the protection scope of the application.
