Description

Technical Field

[0001] This utility model relates to the field of sputum collection technology, and in particular to a sputum collection device for tuberculosis patients. Background Technology

[0002] Pulmonary tuberculosis is an infectious disease of the lungs caused by Mycobacterium tuberculosis. It is a serious threat to human health. During the nursing process, patients with pulmonary tuberculosis often feel uncomfortable because they have a lot of sputum in their bodies. Some patients are unable to cough up sputum due to weakened lung function and need medical devices to assist them.

[0003] For patients who have been diagnosed and are receiving treatment, regular sputum tests can help doctors understand changes in their condition. By monitoring changes in the quantity, type, and cellular composition of pathogens in the sputum, doctors can assess the effectiveness of treatment and adjust the treatment plan in a timely manner, thereby ensuring that patients receive more precise and effective treatment.

[0004] The sealing of collected sputum samples is a crucial aspect of medical quality and safety. Poor sealing can lead to a range of issues, such as misdiagnosis, missed diagnosis, and inappropriate treatment. These problems not only affect patient outcomes and recovery but can also damage the hospital's reputation and credibility.

[0005] Therefore, a sputum collection device for tuberculosis patients is proposed, which has a good sealing effect, ensures the accuracy of sputum sample test data, and thus improves the treatment effect for patients. Utility Model Content

[0006] To address the technical problem that traditional sputum collection devices fail to meet practical application requirements in terms of sealing performance, ultimately affecting test results and leading to poor treatment outcomes for patients, this invention provides a sputum collection device for tuberculosis patients.

[0007] This utility model is achieved using the following technical solution: a sputum collection device for tuberculosis patients, comprising:

[0008] The collection container has a cap threaded to its top, a rubber ring at the bottom of the cap where it connects to the collection container, a sealing mechanism in the middle of the cap, and two symmetrically fixed connecting ports at the top of the cap, both of which are connected to the collection container. The two sets of connecting ports are respectively connected to a sputum collection mechanism and a negative pressure mechanism.

[0009] The sealing mechanism includes two valves, which are installed at the bottom of the cap and at the connection point with the connecting pipe. A rotating groove is provided in the middle of the cap, and a movable groove is provided at the center of the rotating groove. The movable groove passes through the middle of the cap, and a central rotating shaft is rotatably connected inside the movable groove. A baffle is fixedly connected to the outer wall of the central rotating shaft and is rotatably connected inside the rotating groove. The baffle has symmetrical through holes that match the inner diameter of the connecting pipe. A knob is fixedly connected to the top of the central rotating shaft, and the outer wall of the knob is provided with anti-slip protrusions.

[0010] The above technical solution utilizes a closed mechanism to further improve the sealing effect inside the collection container, and, in conjunction with the sputum collection mechanism and negative pressure mechanism, enables rapid sputum sampling from patients.

[0011] As a further improvement to the above solution, the top of the cover is symmetrically and fixedly connected with a stop block, and one side of the stop block abuts a protrusion, which is fixedly connected to the outer wall of the knob.

[0012] The above technical solution ensures that after the stop and the protrusion block block abut against each other, the connecting pipe opening can just match the through hole, thus facilitating the sputum removal operation.

[0013] As a further improvement to the above solution, the sputum collection mechanism includes a connecting cover, which is threadedly connected to one of the communicating pipe ports. A connecting pipe is fixedly connected to the top of the connecting cover, and a fixing cover is fixedly connected to the outer end of the connecting pipe. The fixing cover communicates with the inside of the collection container through the connecting pipe.

[0014] Through the above technical solution, the fixed cover can collect the patient's sputum and the accessories can be replaced to assist in the suctioning process.

[0015] As a further improvement to the above solution, the negative pressure mechanism includes a second connecting cover, which is threadedly connected to another connecting pipe. A second connecting pipe is fixedly connected to the top of the second connecting cover, and an airbag is fixedly connected to the bottom of the second connecting pipe. The airbag communicates with the inside of the collection container through the second connecting pipe.

[0016] As a further improvement to the above solution, a hose is fixedly connected to the bottom of the airbag, and a one-way valve is provided at the connection between the airbag and the connecting tube. A one-way valve is also provided inside the hose.

[0017] The above technical solution utilizes two sets of one-way valves in conjunction with an airbag to create a negative pressure environment for the collection container, thus assisting in sputum collection.

[0018] As a further improvement to the above solution, a groove is provided in the middle of the bottom of the collection container, and a suction cup is fixedly connected to the middle of the groove.

[0019] The above technical solutions can help improve the stability of the collection container during testing and prevent it from being easily tipped over and causing sputum contamination in case of misoperation.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (I) This utility model utilizes a closed mechanism to effectively ensure the airtightness of the collection container during and after sputum collection, reduce the probability of interaction with the outside world, avoid contamination of the collected sputum, and effectively improve the validity of the sample data. This allows for targeted adjustments to the treatment strategy based on the test results, improving the treatment effect and reducing patient suffering.

[0022] (ii) The present invention utilizes a suction cup at the bottom to help the collection container maintain its stability during testing, thus preventing it from being accidentally knocked over and causing sample contamination. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1:

[0031] Please combine Figures 1-4 This embodiment of a sputum collection device for tuberculosis patients includes:

[0032] The collection container 1 has a cap 2 threadedly connected to its top. A rubber ring is provided at the bottom of the cap 2 where it connects to the collection container 1. A sealing mechanism is provided in the middle of the cap 2. Two connecting pipes 5 are symmetrically fixedly connected to the top of the cap 2, and both connecting pipes 5 are connected to the collection container 1. The two sets of connecting pipes 5 are respectively connected to a sputum collection mechanism and a negative pressure mechanism.

[0033] The sealing mechanism includes two valves 8, which are installed at the bottom of the cover 2 and the connection port 5. The cover 2 has a rotating groove 6 in the middle, and a movable groove 7 in the center of the rotating groove 6. The movable groove 7 passes through the middle of the cover 2. A central rotating shaft 9 is rotatably connected in the movable groove 7. A baffle 10 is fixedly connected to the outer wall of the central rotating shaft 9. The baffle 10 is rotatably connected in the rotating groove 6. Specifically, a rubber ring is provided at the connection between the bottom of the baffle 10 and the rotating groove 6. The baffle 10 has symmetrical through holes 11, which match the inner diameter of the connection port 5. A knob 12 is fixedly connected to the top of the central rotating shaft 9. The outer wall of the knob 12 has anti-slip protrusions.

[0034] A stop block 14 is symmetrically fixedly connected to the top of the cap 2. A protrusion 13 abuts against one side of the stop block 14. The protrusion 13 is fixedly connected to the outer wall of the knob 12. Specifically, the protrusion 13 rotates with the knob 12 and stops under the obstruction of the stop block 14. When the knob 12 is blocked, the connecting pipe 5 matches the through hole 11.

[0035] The implementation principle of a sputum collection device for tuberculosis patients in this embodiment is as follows:

[0036] After the equipment is removed, ensure that the threaded connection between the collection container 1 and the cover 2 is sealed to ensure that the environment inside the collection container 1 does not interact with the outside world. Then, install and connect the sputum collection mechanism and the negative pressure mechanism respectively. After installation, use the knob 12 to rotate and make the protrusion 13 abut against the stop block 14 on either side. At this time, the connecting pipe port 5 and the through hole 11 will be in a matching state, which will facilitate the subsequent sputum collection operation.

[0037] After the sputum collection is completed, before disconnecting the negative pressure mechanism from the sputum collection mechanism, turn the knob 12 in the opposite direction to block the connecting pipe port 5 with the baffle 10 and keep it sealed with the help of the rubber ring. Then remove the negative pressure mechanism and the sputum collection mechanism, and send the collection container 1 for testing or store it properly as soon as possible.

[0038] Example 2:

[0039] Combination Figure 2 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0040] The sputum collection mechanism includes a connecting cover 15, which is threadedly connected to one of the connecting pipe ports 5. A connecting pipe 16 is fixedly connected to the top of the connecting cover 15, and a fixing cover 17 is fixedly connected to the outer end of the connecting pipe 16. The fixing cover 17 communicates with the inside of the collection container 1 through the connecting pipe 16. Specifically, a rubber ring is provided at the connection between the connecting cover 15 and the connecting pipe port 5.

[0041] Another embodiment of the fixing cover 17 in this example is as follows: a sputum collection head is provided at the connection between the middle of the fixing cover 17 and the connecting pipe 16, which is used to assist patients with difficulty in coughing up sputum to expel sputum.

[0042] The negative pressure mechanism includes a second connecting cover 18, which is threaded to another connecting pipe port 5. A second connecting pipe 19 is fixedly connected to the top of the second connecting cover 18, and an airbag 20 is fixedly connected to the bottom of the second connecting pipe 19. The airbag 20 communicates with the inside of the collection container 1 through the second connecting pipe 19. Specifically, a rubber ring is also provided at the connection between the second connecting cover 18 and the connecting pipe port 5.

[0043] A hose is fixedly connected to the bottom of the airbag 20. A one-way valve is installed at the connection between the airbag 20 and the connecting pipe 2 19. The one-way valve is installed inside the hose. Specifically, this one-way valve only allows gas to flow from the collection container 1 along the connecting pipe 2 19 to the hose.

[0044] The implementation principle of this embodiment is as follows:

[0045] Patients should rinse their mouths with clean water or saline solution at least three times before collecting sputum to reduce interference from bacteria and debris in the oral cavity. Do not use toothpaste to brush your teeth, as toothpaste residue may affect the quality of the sputum.

[0046] The patient should stand or sit with one hand on their abdomen and the other on their chest, and take 5-6 deep abdominal breaths. Then, inhale deeply, hold your breath for 35 seconds, lean forward, press your hand on your abdomen, and cough forcefully to try to expel phlegm from deep in the trachea.

[0047] After the equipment is assembled, the fixing cover 17 is matched with the patient's sputum. The coughed sputum is then collected at the fixing cover 17. Simultaneously, the air bag 20 is squeezed and pressed, causing the air bag 20 to use two one-way valves to extract the air from the collection container 1, creating a negative pressure environment inside the collection container 1. The sputum collected at the fixing cover 17 is then quickly sucked into the collection container 1 through the connecting tube 16. Under the negative pressure, the valve 8 will open briefly and close quickly, thus completing a single sampling action. Afterward, it can be decided whether to continue the sampling action as needed.

[0048] When encountering patients who are unable to complete the spitting action, a sputum collection head can be used to assist in sputum collection.

[0049] After the sampling is completed, disconnect the threaded connection between the connecting cover 15 and the connecting cover 2 from the connecting pipe port 5, and perform targeted processing according to the actual type of consumables used.

[0050] Example 3:

[0051] Combination Figure 2 This embodiment is further improved upon Embodiments 1 and 2 in the following ways:

[0052] The collection container 1 has a groove 3 at the bottom center, and a suction cup 4 is fixedly connected to the groove 3.

[0053] The implementation principle of this embodiment is as follows:

[0054] When testing is required, the entire collection container 1 is placed on the work surface, and negative pressure adsorption is achieved by the contact between the suction cup 4 and the work surface, which improves the stability of the collection container 1 and avoids accidental spillage and contamination.

[0055] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
