Description

Technical Field

[0001] The invention relates to the technical field of sputum collection and processing, and in particular to a sputum collection and processing device used by patients with pulmonary tuberculosis in respiratory medicine. Background Art

[0002] The main symptom of pulmonary tuberculosis patients is coughing accompanied by sticky sputum. Since the sputum of patients with sputum-positive pulmonary tuberculosis is contagious, in order to prevent the patient's sputum from being exposed to the air and causing airborne infection, the sputum needs to be collected and processed.

[0003] At present, sputum collection containers are added with disinfectant to achieve collection and disinfection. However, it takes a certain amount of time for the disinfectant to completely disinfect the sputum. Although the sputum in the lower part of the container is in contact with the disinfectant for a longer time, when the collected sputum needs to be poured out, the sputum in the upper part of the collection container, especially the sputum wrapped in a paper towel, is often not effectively disinfected. This situation still requires strict follow-up treatment methods, and the sputum of tuberculosis patients collected in this way is also at a high risk of infection during the treatment process.

[0004] The Chinese patent with application number CN202210671484.7 discloses a disinfection device for preventing tuberculosis infection, including a barrel body, an encapsulator installed on the barrel body, a collection bag arranged in the barrel body, an encapsulator provided with an encapsulation port, and a disinfector, a controller and an electric telescopic rod are installed, electric unwinders are arranged on both sides of the encapsulation port, plastic film is wound on both electric unwinders, a hot melt knife is installed on the telescopic end of the electric telescopic rod, and the hot melt knife, electric unwinder, disinfector and electric telescopic rod are all electrically connected to the controller. The patent heat-melts the bag opening to seal the container, so that the vessel containing sputum is sealed and stored, and is not prone to leakage risk, so that the vessel containing sputum can be collected, transported and moved in large quantities more safely, so as to facilitate centralized incineration, destruction or disinfection.

[0005] However, the above technology still has the following problems: 1. It is difficult to directly use it to collect sputum and paper towels wrapped with sputum and disinfect them; 2. The structure is complex and contains high-cost components such as motors, the production cost is high, and it is not easy to promote; 3. The real-time hot-melt bag packaging is prone to collection and processing risks due to equipment failure, power outages and other problems, and the reliability is poor.

[0006] The Chinese patent application number CN03231268.7 discloses a strong plastic ziplock bag. Compared with ordinary plastic ziplock bags, the number of sealing grooves, adhesive edges and the area of ​​adhesive edges are increased or enhanced. Therefore, the sealing effect is good, and sputum can be contained without overflowing, even under a certain pressure. People who spit can spit into the "strong plastic ziplock bag", then put it in a pocket or bag, and throw it into the waste bin at an appropriate time. Therefore, the "strong plastic ziplock bag" can effectively cure the bad habit of "spitting everywhere".

[0007] Although using ziplock bags directly can seal and collect sputum simply and at low cost, it is difficult to open the ziplock bags again once they are sealed. Forcing the bag open can easily tear the bag opening and cause the contents to spill. It is not easy to reuse and requires a lot of consumables. Secondly, it is easy for the ziplock bags to drop when collected by hand, which is especially important when used to collect sputum from tuberculosis patients. Thirdly, it is inconvenient to disinfect the ziplock bags, and the bags containing sputum need to be collected again for centralized disinfection. In addition, the storage of many ziplock bags is chaotic, which makes it difficult to determine the remaining amount and leads to a shortage of collection bags.

[0008] It is necessary to design a sputum collection and processing device that can use a ziplock bag as a collection bag and solve the problems of opening and fixing the ziplock bag, convenient storage and retrieval, replacement reminder, forgetting to add disinfectant to the ziplock bag, and when and how to add disinfectant to the ziplock bag, so as to meet the needs of sputum collection and processing patients with pulmonary tuberculosis in the respiratory department.

[0037] Due to the adoption of the above technical solution, the advantages of the present invention are:

[0038] 1. The sputum collection and processing device provided by the present invention for use by patients with pulmonary tuberculosis in the respiratory department can not only conveniently store the ziplock bag roll group to be used in the collection bucket, but also when adding and replacing the ziplock bags, the new ziplock bag can be pulled into the collection bucket in the process of removing the sealed ziplock bag, so that adding and replacing can be conveniently performed, and there is no need to hold the ziplock bag with hands all the time during the taking process, which is convenient to take and use, and also avoids the risk of contamination such as accidental slipping of the ziplock bag that contains sputum and has not been sealed.

[0039] 2. The present invention uses a ziplock bag as a collection bag, which has a more reliable seal, can effectively avoid the risk of dirt leakage, and can significantly reduce the complexity and cost of the collection and treatment device.

[0040] 3. The present invention can realize that the pump liquid assembly sprays a certain amount of disinfectant into the ziplock bag while fixing the bag opening after the ziplock bag is opened. In the process of replacing the ziplock bag, as the pressing part of the pump liquid assembly is pressed down, the opening support piece releases the fixation of the ziplock bag, and the pump liquid assembly can spray the disinfectant onto the sputum in the ziplock bag again. Not only is the utilization rate of the disinfectant high, but the addition of the disinfectant is more uniform, sufficient and convenient. After the bag opening is sealed, the disinfectant can still fully disinfect the sputum in the bag for a long time, and the disinfection treatment is more thorough. The collected sputum does not need to be collected and transported again for centralized disinfection treatment, and the risk of secondary contamination is less likely to occur, and the treatment is simpler and safer.

[0041] 4. The present invention can realize the linkage of the support member while spraying the disinfectant. It is only necessary to consider pressing the pressing part to lift the hook-shaped member and place the upper membrane edge on the hook-shaped member, and then release the pressing member to make the hook-shaped member fall back again to automatically fix the upper membrane edge. There is no need to consider when and how to add the disinfectant to the ziplock bag (according to the properties of the disinfectant used and the required amount of addition, the cylinder with a suitable volume can be set. When the piston assembly is pressed, the disinfectant sucked into the cylinder can be sprayed into the ziplock bag, and it is only necessary to consider pressing the pressing member to lift the hook-shaped member. During this pressing operation, a certain amount of disinfectant can be injected into the ziplock bag just after the ziplock bag is unfolded and before the ziplock bag is sealed), and the operation is simpler and more convenient.

[0042] 5. The V-shaped inner barrel of the present invention can not only hold the ziplock bag, but also, due to the V-shaped structure, a small amount of disinfectant added therein can achieve a higher level of the disinfectant liquid level, so that a small amount of disinfectant can more efficiently and effectively disinfect the outside of the bottom of the ziplock bag for a long time.

[0043] 6. The color of the ziplock bags close to the core tube included in the ziplock bag roll set disclosed by the present invention is different from the color of the ziplock bags far from the core tube, which can prompt that a new ziplock bag roll set is ready to be added.

[0044] 7. The present invention can realize that the moving position and amplitude of the hook-shaped member can be controlled by a gear during the up and down movement of the straight tube portion only by setting the length of the rack on the hook-shaped member. The rack on the hook-shaped member can be meshed with the gear again in time by a spring arranged between the hook-shaped member and the baffle. The control structure is simple and effective with low cost. BRIEF DESCRIPTION OF THE DRAWINGS
