Description

Sputum collector

Technical Field

The invention relates to a container for collecting sputum in the field of medical instruments, in particular to a disposable sputum collector convenient for collection, storage and transportation.

Background

Lung cancer is the leading malignancy of morbidity and mortality worldwide. Despite the great improvements in current therapies, the overall survival rate of lung cancer remains low with a median survival time of about 15 months. But compared with the late-stage lung cancer patients, the 5-year survival rate of the early-stage lung cancer patients after treatment is over 90 percent, so that the survival rate of the patients is greatly improved and a large amount of social resources are saved by screening the early-stage lung cancer. The sputum contains somatic cells and tumor cells, so that the sputum can detect lung cancer related cancer genes, and becomes one of very effective noninvasive means for early lung cancer screening. However, the current single-day and single-time sputum collection cassette is only suitable for some routine examinations, and cannot obtain sufficient somatic cells or tumor cells from the sputum. Therefore, the sputum collector capable of continuously collecting and storing for multiple days is designed, the requirement of screening early lung cancer is met, and the defects of the conventional sputum collecting box are overcome.

In hospital clinics, determination of the cause of a disease by patient sputum is a common examination. In a simple case, a container is usually given to a patient, and the patient himself spits out sputum into the container, and then carries out culture and assay to obtain an examination result. Under the complex condition, when tracheotomy or trachea cannula patient need do the phlegm and cultivate, often need medical personnel to use the sputum taking device to get the phlegm, the sputum that takes out shifts to the container in, then goes to cultivate, the chemical examination obtains the inspection result. Of course, hospitals in many small and medium-sized cities and even remote areas do not have personnel or equipment for culture and assay, and sometimes need to transport the container for collecting sputum to a large remote hospital for further treatment.

Because the sputum of a patient often contains a large amount of germs, in some cases, the sputum of a tuberculosis patient has extremely strong infectivity and the survival ability of the germs is strong, and if the sputum of the patient is not treated well, the sputum may have high risk to cause infection, which leads to the spread of the disease. The prior sputum collecting container is usually a plastic cup, and some of the prior sputum collecting containers are provided with a cover to facilitate sealing of the container. Since the amount of sputum to be collected for culture and assay is not large, the conventional container is not usually large, that is, the opening of the container for collecting sputum is usually small, and thus an additional funnel is required to be provided at the opening portion of the container for collecting sputum. For example, the collection funnel structure is specifically provided in chinese patent application CN 201520419217.6 and chinese patent application CN 201520089900.8. Although these funnel structures can be discarded after disposable, increase the cost after all, also can bring the gap that easily hides the germ in structural connection simultaneously, and the increase in funnel structure volume also is inconvenient for the save and the transportation of sputum simultaneously.

On the other hand, if a container with a larger opening is used for collecting sputum, a small amount of sputum in the container is easily stained on the wall of the container and dried during transportation, so that pathogenic bacteria and the like contained in the sputum are changed, the etiological factors cannot be accurately found, a correct treatment method is formulated, and the illness state is delayed. Meanwhile, the larger opening container also causes the volume to increase, which causes difficulty in the storage and transportation of the sputum.

Furthermore, after the sputum collection container is sent to the laboratory, the container still needs to be opened again, and the sputum in the container is sucked out through a straw or the like for the next work. The container just has a large amount of germs to get into the air in the moment of opening the container cover through long-time storage and transportation, and the pungent smell of sputum in the container can also be discharged simultaneously, and the color that the sputum vomits also can be presented before the eyes of laboratory staff, bears the huge puzzlement that causes to laboratory staff's health and psychology. The existing sputum collection container cannot overcome the problems, and a new sputum collection container needs to be developed.

Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

Just as the background art part said, because the mode that the sputum was collected to current sputum collecting container is inconvenient, needs extra funnel structure, leads to the structure bulky, is difficult for preserving the transportation, and the easy drying of sputum is rotten, opens after collecting and causes easily pollution and germ to spread.

Therefore, in view of the above-mentioned drawbacks of the prior art, the present invention provides a sputum collector with an innovative structure, as shown in fig. 1, which is a schematic view of an opened state of the sputum collector according to an embodiment of the present invention, and as shown in the figure, the sputum collector of the present invention comprises a container 100 consisting of a box 1 for containing sputum and a cover 2 for covering the box 1. Wherein, the box body 1 is evenly divided into a plurality of independent box units 12 containing sputum through the box partition 11, and the cover body 2 is divided into a plurality of cover units 22 corresponding to the box units 12 in shape through the cover partition 21.

In particular, the container 100 of the present invention may be formed by injection molding a single piece of medical plastic, with the body 1 and the lid 2 being cube-shaped and joined together by a common side 10, as shown. The wall thickness at the location of the side 10 where the box body 1 and the cover body 2 are connected is relatively thin, so that the cover body 2 can rotate around the side 10, forming a structure in which the cover body 2 is hinged to the box body 1 through the side 10. The integral injection molding structure is very simple, easy to process and low in cost. Wherein, box wall 11 and lid wall 21 are once only formed while moulding plastics, have formed a plurality of independent box units 12 between the box wall 11, have formed a plurality of lid units 22 between the lid wall 21 correspondingly too, it is almost the same that the structure of the box body 1 and lid 2 is seen in the figure, therefore facilitate the manufacturing of the mould, can further reduce cost.

It should be noted that the lower side of the case 1 and the upper side of the cover 2 are hidden from view in view of the perspective, and the case 1 and the cover 2 are structurally different, that is, the lower side of the case 1 has a complete bottom (hidden from view in view of fig. 1) because the case 1 is formed as the box unit 12 for containing sputum. The upper side (the upper part can be seen in fig. 2) of the cover 2 is hollowed, that is, only the cover partition 21 and the four peripheral walls are arranged on the cover 2, and both sides of the cover unit 22 are hollowed during injection molding.

Of course, it should be understood by those skilled in the art that since the cover partition 21 shown in fig. 1 is a dotted line, i.e., it is indicated that in the state of fig. 1, the side of the cover partition 21 is covered with a structure, i.e., in one embodiment, both sides of the cover unit 22 are firmly adhered and covered with an inner transparent film 23 and an outer transparent film 24 (since the two structures are transparent films, which are not shown in the drawings, the corner portions of the transparent films are particularly tilted in the drawings so as to show that they are one film, and the text description of the present invention should be easily understood by those skilled in the art), wherein the outer transparent film 24 can also be seen in fig. 2. In fig. 2, which is an exploded view showing a closed state of a sputum collector according to another embodiment of the present invention, it can be seen from fig. 2 that an opaque cover layer 4 is further detachably adhered to the outer side of the outer transparent film 24.

Specifically, the inner transparent film 23 and the outer transparent film 24 may be transparent films made of a material such as PET plastic, that is, the sputum contained in the case 2 can be seen through the two films. The lid partition 21 is used for supporting and adhering the inner transparent film 23 and the outer transparent film 24, and for firmly clamping the inner transparent film 23 through the lid partition 21 and the corresponding box partition 11 when the box unit 12 is closed, so that a sealed lid formed by the inner transparent film 23 can be formed above the box unit 12, the containing spaces of the box units 12 are independent, and sputum cannot flow between different box units 12. The effect of setting up such independent accommodation space is when for follow-up sample chemical examination, can only take the sample once in a box unit 12 at every turn, avoids secondary sampling to pollute the sample, has improved the accuracy of chemical examination result.

Of course, although a transparent film is provided to facilitate viewing of sputum, sputum may be perceived as very nausea and may be subject to change under light conditions, and therefore the present invention further provides an opaque cover layer 4 which is initially adhered to the outer side of the outer transparent film 24 and which can be peeled away from the outer transparent film 24 to facilitate viewing when an assay is required after collection of the sputum. In one embodiment, the cover layer 4 may be an opaque sticker with adhesive or an opaque plastic sticker with adhesive, and the surface thereof may be used to write information such as patient name, collection time, sample number, and the like.

Further, as shown in fig. 1-2, in a preferred embodiment, the open side of the cassette unit 12 is also surrounded by a ring of skirting paper 3. That is, as shown in the figure, the skirted paper 3 is adhered around the opening side of the box unit 12 like an apron by a soft paper towel, and in fig. 1, for the convenience of clearly showing the structure of the cover 2, the skirted paper 3 at the position of the side edge 10 where the box body 1 and the cover 2 are connected is omitted, and in actual use, the skirted paper 3 is arranged around the four side walls of the box unit 12, and only the skirted paper 3 at the connecting part of the box body 1 and the cover 2 partially shields the cover 2.

When the sputum collection box is used, the bottom of the box body 1 is held by a hand, the skirt paper 3 is spread out, a patient can spit out sputum opposite to the box body 1, or the sputum is collected by the sputum collector and transferred to the box unit 12 of the box body 1, the skirt paper 3 is similar to a soft apron carried on the box body 1, and if the sputum is splashed to the outer side of the box body 1, the skirt paper 3 can be caught by the skirt paper 3. The sputum collection finishes, tears the shirt rim paper 3 that will extend to the box body 1 outside and gets rid of and can avoid the sputum that splashes the box body 1 outside to pollute the exterior structure of container 100.

In one embodiment, the skirt paper 3 includes an inner skirt 31 and an outer skirt 32 divided along the edge of the case 1, and tear holes are provided between the inner skirt 31 and the outer skirt 32. After the sputum is collected, the outer skirt 32 is preferably torn away along the tear hole. In fig. 1 and 2, the tearing holes are overlapped along the edge of the box body 1, the inner skirt 31 extends into the edge of the box body 1 and partially covers the box partition 11, so as to facilitate firm adhesion, avoid pulling the inner skirt 31 when the outer skirt 32 is torn off, and prevent the external structure from being contaminated by dirt once sputum and the like exist on the inner skirt 31.

In one embodiment, as shown in the figure, the cover 2 may further be provided with a fastening structure 25 for fastening the box 1, of course, it should be understood by those skilled in the art that one or more fastening structures 25 may be provided, as long as the box 1 and the cover 2 can be fastened tightly. In addition, a weather strip structure may be further provided around the lid 2 and the case 1, and the sealing performance may be further improved.

In still another embodiment, as shown in fig. 1, the inner transparent film 23 is provided with a slit 26 formed by circularly arranged tearing holes corresponding to the middle position of each cassette unit 12, so that the straw pierces the slit 26 to suck sputum during testing. Of course, the inner transparent film 23 is not completely sealed due to the tear hole, which has the advantage that the gas generated during the sputum culture process is released upwards along the tear hole, and if it is completely sealed, the gas can only be released from the gap between the cover body 2 and the box body 1, and may carry part of the sputum out of the container 100 to cause contamination. Further, since the outer transparent film 24 is a sealed structure having no air holes, there is no fear that contaminants may overflow from the outer transparent film 24 after passing through the inner transparent film 23.

During the assay, the cover layer 4 is first peeled off from the outer transparent film 24, which box unit 12 contains the sputum (it is impossible to ensure that the sputum can be spitted in each box unit 12 during the collection, and it is not necessary to transfer and fill the sputum in each box unit 12), and then the outer transparent film 24 is punctured. Because of the insulating effect of the inner transparent film 23, there is no fear that a large amount of gas or liquid is ejected, and after all, the tear hole in the inner transparent film 23 is very small. A sample can then be taken directly from the cassette unit 12 by piercing the breach 26 with a sample pipette.

According to the structure arrangement, due to the arrangement of the skirt paper during collection, dirt is prevented from being stained with an external structure. After collection, the container does not need to be opened again at all, thereby avoiding the problem of large-scale diffusion of germs and the like. And the sputum is observed and sampled through the transparent film, so that the psychological interference of nausea of operators is avoided. The independent box unit is arranged, so that a sample can be taken from one box unit at a time, the secondary sampling is avoided from polluting the sample, and the accuracy of the test result is improved.

Of course, it is sometimes not well determined which cassette unit 12 contains sputum by human eye observation, and therefore, in a preferred embodiment, a colored water-wettable paper or cloth is provided on the bottom of each cassette unit 12. After the water in the sputum soaks paper or cloth like this, because the effect of light, the colour of paper or cloth can become dark, just so judges very easily that has the sputum in which box unit 12, just so convenient when extracting the sample, can practice thrift the sample time, has reduced the probability that secondary pollution takes place.

Further, fig. 3 shows a schematic structural view of a sputum collector according to another embodiment of the present invention, and as shown, the sputum collector of the present invention may further comprise a transport bag 5 for hermetically packaging the container 100. After sampling, the container 100 can be hermetically packaged in the transport bag 5, the bag opening is sealed through the lock catch 51, then the container 100 collected with sputum can be transported to a mechanism with detection capability through postal express delivery and the like for detection, and the hermetically packaged transport bag can be convenient for collection, storage and transportation. After the test and detection are finished, the whole container 100 can be directly treated as waste, and the sputum in the container cannot overflow everywhere, so that the problem of spreading infectious germs is avoided.

In summary, the above-described structure of the present invention provides a single-use sputum collector which is convenient for collection, storage and transportation.
