Description

Technical Field

[0001] This utility model relates to the field of fecal collection technology, specifically a fecal specimen collection bag. Background Technology

[0002] Stool specimens are of great importance in clinical laboratory testing, primarily used to understand the health of the digestive tract, including the presence of bleeding, inflammation, parasitic infections, and tumors. Different testing methods are used depending on the specific purpose of the examination. For example, routine examinations may involve microscopic observation of stool shape and color; culture specimens may use bacterial culture methods to detect intestinal bacteria; cytological examinations may use cytological staining to observe cancer cells and abnormal cells; parasitological examinations may use methods such as precipitation and centrifugation to concentrate parasite eggs and cysts; and virological examinations may use methods such as viral culture and nucleic acid detection.

[0003] When collecting stool samples from patients, the patients should defecate naturally into a bedpan or toilet that is easy to clean. Use clean cotton swabs, stool collection spoons, or sterile cotton swabs to collect an appropriate amount of sample from different parts of the stool (such as the central part, the mucus and bloody part).

[0004] However, the following problems still exist in the current stool collection process: patients need to provide stool samples during hospitalization, but the toilets in the wards are mostly designed with toilet seats. Patients often complain that it is inconvenient to provide stool samples with these toilet seats. The stool is mixed with urine in the toilet bowl, making it difficult to collect. At the same time, if the patient has diarrhea symptoms and the stool is unformed, it is even more difficult to cooperate in providing samples for testing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stool sample collection bag. By using the collection bag, stool and urine can be separated, ensuring the cleanliness of the collected stool.

[0006] This utility model provides the following technical solution: a stool sample collection bag, including a support layer, a first filter layer fixedly disposed on its inner surface, and a second filter layer fixedly disposed on the inner surface of the first filter layer; a first pull strap fixedly disposed at the lower end of the support layer, and a second pull strap fixedly disposed at the lower end of the support layer, and the second pull strap is connected to the first pull strap; two fixed long pull straps are symmetrically disposed on the outer side of the support layer, and a first adhesive layer is fixedly disposed at the lower end of the fixed long pull straps, and a first release film is adhered to the lower end of the first adhesive layer; a permeable layer is adhered to the inner surface of the second filter layer, and a tear-off layer is disposed at the upper end of the permeable layer.

[0007] Furthermore, both the first and second pull belts are configured as elastic belts with slight elasticity, and the first and second pull belts are staggered. Through the above structure, the first and second pull belts are prevented from being torn or broken during the process of collecting feces.

[0008] Furthermore, both the support layer and the tear-off layer are configured as annular structures, and the first and second water-filtering layers on the support layer are both made of water-filtering non-woven fabric. Through the above structure, it is easy to filter out urine from feces through the first and second water-filtering layers.

[0009] Furthermore, a short pull strap is fixedly provided on the side of the support layer, and a second adhesive layer is fixedly provided at the lower end of the short pull strap. A second release film is fixedly provided at the lower end of the second adhesive layer. With the above structure, the second adhesive layer can be easily bonded to the toilet by tearing open the second release film.

[0010] Furthermore, the permeable layer is also made of a non-woven filter material, and the pores of the permeable layer are smaller than those of the first and second filter layers. With the above structure, it is convenient to retain and collect the filtered feces through the permeable layer.

[0011] Furthermore, the lower end of the release layer is provided with a ring-shaped receiving layer, and the lower end of the receiving layer is provided with a ring-shaped fixing adhesive. The lower end of the fixing adhesive forms an adhesive connection with the upper end of the support layer. Through the above structure, it is easy to fix the release layer to the upper end of the support layer by fixing adhesive.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This stool sample collection bag filters out urine from excrement through a first filtration layer, a second filtration layer, and a permeable layer, ensuring the cleanliness of the collected stool sample. This makes it convenient for patients to collect samples and is also suitable for patients with diarrhea. The first adhesive layer and the fixing long strap can stably fix the support layer to the toilet, preventing the support layer from moving or falling off during use. Furthermore, by removing the permeable layer and the tear-off layer separately, stool samples can be collected separately when a patient has diarrhea, facilitating subsequent stool testing.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a stool sample collection bag, including a support layer 1, on the inner surface of which a first filter layer 4 is fixedly disposed, and on the inner surface of the first filter layer 4 a second filter layer 5 is fixedly disposed. A first pull strap 2 is fixedly disposed at the lower end of the support layer 1, and a second pull strap 3 is fixedly disposed at the lower end of the support layer 1, and the second pull strap 3 is connected to the first pull strap 2. Two fixed long pull straps 6 are symmetrically disposed on the outer side of the support layer 1, and a first adhesive layer 7 is fixedly disposed at the lower end of the fixed long pull straps 6, and a first release film 8 is adhered to the lower end of the first adhesive layer 7. A permeable layer 12 is adhered to the inner surface of the second filter layer 5, and a tear-away feature is provided at the upper end of the permeable layer 12. The release layer 13, the first pull band 2 and the second pull band 3 are both set as elastic bands with slight elasticity, and the first pull band 2 and the second pull band 3 are in an alternating state. The support layer 1 and the release layer 13 are both set as annular structures. The first filter layer 4 and the second filter layer 5 set on the support layer 1 are both made of filter non-woven fabric. A fixed short pull band 9 is fixedly set on the side of the support layer 1, and a second adhesive layer 10 is fixedly set at the lower end of the fixed short pull band 9. A second release membrane 11 is fixedly set at the lower end of the second adhesive layer 10. The permeable layer 12 is also made of filter non-woven fabric. The filter pores of the permeable layer 12 are smaller than the filter pores of the first filter layer 4 and the second filter layer 5.

[0022] When it is necessary to collect the patient's stool, pull the second release film 11 to move it away from the second adhesive layer 10 until it is peeled off from the bottom of the second adhesive layer 10. Then, adhere the second adhesive layer 10 to the top of the toilet seat (for ease of drawing, the collection bag is drawn as a circle, but it can be adjusted to an elliptical shape or other structures according to the shape of the toilet). At this point, the second adhesive layer 10 can be fixed to the toilet seat. Then, pull up the toilet seat and peel off the first release film 8. At this point, the first release film 8 is no longer adhered to the bottom of the first adhesive layer 7, allowing the fixed long pull to... The strap 6 is wrapped around the lower end of the toilet seat and thus adhered and fixed to the lower end of the toilet seat, thereby fixing the short strap 9 and the long strap 6. The collection bag can be fixed to the toilet seat. Since the long strap 6 and the short strap 9 are fixed to the support layer 1, the support layer 1 can be fixed, and the permeable layer 12 can be fixed, so that the patient's excrement can be collected. Since the first filter layer 4, the second filter layer 5 and the permeable layer 12 are made of non-woven filter material, the urine in the excrement will begin to be filtered out, so that the stool can be collected, which is convenient for stool sampling.

[0023] The lower end of the release layer 13 is provided with a ring-shaped support layer 14, and the lower end of the support layer 14 is provided with a ring-shaped fixing adhesive 15, and the lower end of the fixing adhesive 15 is bonded to the upper end of the support layer 1.

[0024] When the patient's stool is loose, pull the tear-off layer 13. The lower end of the tear-off layer 13 is provided with a support layer 14, and the lower end of the support layer 14 is provided with a fixing adhesive 15. At this time, the fixing adhesive 15 is no longer attached to the upper end of the support layer 1. Under the action of the support layer 14, the fixing adhesive 15 can be prevented from breaking when it is torn. At this time, the permeable layer 12 can be removed, and the stool collected in the permeable layer 12 can be taken out for medical staff to test. Then pull the toilet seat to tear off the fixing long pull strap 6 and fixing short pull strap 9. At this time, the support layer 1 can be removed, and the used collection bag can be removed.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
