Description

Portable Sputum Collector

technical field

The invention relates to a sanitary appliance, in particular to a sputum collecting device.

Background technique

Sputum contains mucus, inhaled dust, various inflammatory cells, and necrotic and exfoliated mucosal epithelial cells in the respiratory system, necrotic tissue, bacterial viruses and other pathogenic substances. Among them, these pathogenic microorganisms are transmitted through the respiratory tract and can cause human diseases, especially the sputum of tuberculosis patients contains a large number of conjugate bacilli, which are highly infectious. Tuberculosis is one of the causes of lung cancer, which ranks first in the incidence of malignant tumors. The common clinical manifestations of lung cancer are coughing up sputum and hemoptysis. According to the survey, the incidence of tuberculosis remains at a high level.

Clinical observation found that patients collected coughed up sputum or blood into disposable cups or spittoons, and often did not cover the cups filled with sputum. Sometimes, in order to observe the sputum or blood coughed up by the patient to the doctor, especially the coughed up blood, the patient or the family member of the patient will collect the excretion of the night in a completely exposed manner. After some unaccompanied patients spit out sputum, it is also difficult to deal with the sputum in time. There are even some patients who spit sputum directly on the ground and so on.

However, some bacteria or pathogens in sputum have a very high survival rate. For example, Mycobacterium tuberculosis with strong resistance can survive for half a year in a dark and humid place indoors. Tuberculosis is transmitted through the air. If the sputum and blood coughed up by the patient are not treated in time, or the untreated sputum is directly poured into the household garbage, it will not only cause secondary pollution to the ward environment, but also cause serious harm to the patient's family members and fellow patients. Or there is a risk of cross-infection among staff.

Detailed ways

The portable sputum collector 100 shown in FIGS. 1 to 4 includes an outer container 1 and an inner container 2 . The inner container is used for storing sputum, and the inner container is put into the outer container when in use. The outer container is provided with a laterally opened outer container side cover 11, and a spit opening 12 and a spit opening cover 13 are opened on the upper part of the outer container. The top of the inner container 2 is provided with an inner container top cover 21 . During the process of collecting sputum by the portable sputum collector, the inner container 2 is accommodated in the outer container 1, and the top cover 21 of the inner container is removed so that the opening of the inner container is opposite to the spit opening of the outer container, and the patient's sputum is discharged from the outside. The spit of the container enters the inner container.

In one design, the spit opening of the outer container is pear-shaped, that is, the spit opening shown in Figures 1 and 2 has a narrow upper end and a wider lower end. This design conforms to the characteristics of the human face. The narrow upper end 121 just fits the patient's nose, and the wide lower end 122 fits the human chin. When the patient spits, let the nose lean against the upper end of the spit mouth and the chin lean against At the wide lower end, the mouth of the patient is completely inside the outer container, so that spitting is completed without splashing the sputum to the outside of the collector.

The shape of the spit port cover can be designed as follows but not limited to the enumerated scheme. The lid of the spitting mouth can be a door-opening cover whose shape is the same as or different from the spitting mouth, as long as it can cover the spitting mouth. In the manner shown in Figures 1 to 4, the upper part of the outer container is designed as a spherical structure, the spit opening 12 is arranged on the spherical structure, and the spit opening cover is also of a spherical structure, which is connected to the spherical structure with a hinge 25, and It can be turned around the ball so that the spit can be covered or opened. Such a spherical design can save the space occupied by the sputum collector, and the patient can use some fingers to open the spherical cover at the same time while holding the sputum collector. The operation is simple and there is no need to worry about the cover rebounding and hitting his face.

In one design solution, the top cover 21 of the inner container movably cooperates with the inner container. For example, in the designs shown in Figures 5 to 7. Guide grooves 22 are opened on opposite side walls of the inner container, and first fixing holes 221 and second fixing holes 222 are sunken at both ends of the guide grooves. The bottom of the top cover 21 of the inner container is provided with a guide rod 23, which can move in the guide groove and fall into the fixing hole. When the top cover guide rod 23 is inserted into the first fixing hole 221, the top cover just covers the inner container. When the top cover guide rod 23 was removed from the first fixing hole 221 and moved into the second fixing hole along the guide groove 22, the top cover was suspended on one side of the inner container, and there was no top cover to block the opening of the inner container. Accept sputum. This not only prevents the lid with sputum germs from being placed separately from the sputum collector to pollute the environment, but also facilitates the opening and closing of the opening of the inner container.

In order to prevent sputum from being spit on the inner wall of the outer container, in the design scheme shown in Figure 8, the portable sputum collector also includes a funnel 3, which can be fixed and non-detachable installed in the outer container. The funnel can also be flexibly connected, that is, it can be detachably installed in the outer container. The large mouth end 31 of the funnel 3 faces the spit mouth of the outer container, and the small mouth end 32 of the funnel faces the opening of the inner container. The sputum spit from the spitting port is collected by the funnel, and flows into the inner container accurately from the small opening along the inclined wall of the funnel.

Because mucin in sputum forms a protective layer around bacteria (such as Mycobacterium tuberculosis in sputum), it is difficult for rays and disinfectants to penetrate. Therefore, 5% carbolic acid or 20% bleach for disinfection of sputum must be treated for 24 hours after disinfection. The sputum is safer. And 70% alcohol can kill Mycobacterium tuberculosis in the sputum after 2 minutes of contact with the sputum. In order to achieve faster disinfection of sputum, the portable sputum collector also includes a liquid injection tube 5, the liquid injection tube passes through the outer container wall and is fixedly connected to the collector, and its liquid inlet 51 is arranged on the collector. The outer side of the collector, the liquid outlet 52 is arranged on the inner side of the collector. As shown in Figure 8, the liquid outlet of the liquid injection tube is located above the funnel; as shown in Figure 9, the liquid outlet of the liquid injection tube is directly above the opening of the inner container; or the liquid injection tube includes a liquid inlet and two One liquid outlet is located above the funnel, and the other liquid outlet is located above the opening of the inner container. Before the inner container with sputum needs to be taken out, the syringe 7 with 70% alcohol is connected to the liquid inlet of the injection pipe, and the alcohol enters the inside of the collector through the liquid outlet of the injection pipe, so that the alcohol can affect the funnel, the content Disinfection of equipment, etc. The liquid inlet end of the injection tube can also include a sealing cover, and when the collector collects sputum, the liquid inlet is covered by the sealing cover, so as to prevent germs in the sputum from spreading into the air from the injection tube. In another further improved design, a one-way valve is installed at the liquid outlet end of the liquid injection pipe, and the valve can only be opened in the direction of the collector, so the disinfectant can enter the collector through the liquid outlet, and the sputum The virus in the liquid cannot enter the liquid injection tube from the liquid outlet. In a more optimal design, there is also an atomizer on the end of the liquid outlet, so that the injected disinfectant is atomized into fine droplets, so that it can be evenly and effectively spread to all corners of the funnel or the inner container, making the tuberculosis easier. Disinfection of bacteria.

In the solution shown in Figures 10 and 11, the portable sputum collector also includes a scissor switch 6 with a spring to control the opening and shielding of the opening of the inner container placed in the outer container. The scissor-type switch is fixedly installed on the outer container and located above the opening of the inner container; when there is a funnel, the scissor-type switch can be fixedly installed on the outer container and located above the large mouth end of the funnel. The scissor switch includes two openable and closable cover sheets 61 , a finger insertion portion 63 and a control spring 65 . The cover sheet 61 is located inside the collector, the finger insertion part 63 is located outside the collector, and the control spring can be connected between the finger insertion parts or between the cover sheets. Take the example shown in the figure to further illustrate the function of the control spring. As shown in Fig. 10, when the two cover sheets touch together to cover the opening of the inner container, the spring connected to the finger insertion part is in the original state. As shown in Figure 11, when the patient needs to spit into the inner container, the finger insertion part is used to open it outward like scissors, and the two covering sheets are separated to expose the opening of the inner container. At this time, it is connected to the finger insertion part The spring is also pulled apart. When the spitting is finished and the finger is withdrawn from the finger insertion part, the finger insertion part is automatically retracted due to the resilience of the spring, which also drives the cover sheets to touch together again so as to automatically close the opening of the inner container. With such a design, even if the patient forgets to cover the spit opening of the outer container, the sputum collector will automatically cover the opening of the inner container through the scissor-type switch, so as to prevent germs in the sputum from spreading to the external environment.

Examples of clinical applications of the portable sputum collector. The patient puts the clean inner container 2 into the outer container 1 before use. The specific operation is: open the side cover 11 of the outer container, put the inner container into the outer container from the side; slide and remove the top cover 21 of the inner container to open the contents Close the side cover of the outer container, and lock the side cover of the outer container with the locking device 123 to avoid accidental opening during use. When the patient spits, the nose leans against the upper end 121 of the narrow portion of the spit opening 12 of the outer container, and the chin leans against the lower end 122 of the wide portion, and spits into the inner container. If the sputum collector is equipped with a scissor-type switch, open the cover sheet of the switch when spitting, and release the finger on the scissor-type switch after spitting, and the cover sheet will automatically touch the switch again under the spring's resilience. together to cover the inner container opening. When not spitting at ordinary times, cover spitting mouth lid 13. When the sputum contained in the inner container is to be dumped, 70% alcohol is injected into the inner container through the liquid injection pipe 5, and the alcohol is maintained for at least 2 minutes. After the disinfection is finished, open the side cover 11 of the outer container, push back the top cover 21 of the inner container to the opening of the inner container, and the guide rod 23 of the top cover falls into the first fixing hole 221, which prevents the top cover from moving In case of accidental movement during handling, followed by removal of the inner packaging with the top lid on from the outer packaging. Whether the patient is using the sputum collector or taking out the inner container containing the sputum, the patient's sputum is sealed in the collector, effectively preventing the sputum from being affected by the external environment.

The portable sputum collector can not only be used in hospital wards, but also can be used by people who often cough and have a lot of phlegm at home, so it has a wide application prospect.
