Abstract
Description
Technical Field
[0001] The invention relates to the technical field of surgical instruments, in particular to a dry and hard stool extractor and a segmented sampling tube. Background Art
[0002] Hard stool is a common manifestation of constipation. Hard and dry stool usually manifests as difficulty and effort in defecation, and the stool is dry, lumpy or ball-shaped. Sometimes it may be accompanied by symptoms such as anal pain, anal fissures or hemorrhoids. It may be caused by a variety of factors. Insufficient daily water intake will lead to too little water in the intestines, and the stool becomes dry and hard; lack of vitamins and dietary fiber in the diet, or excessive intake of high-fat, high-sugar, low-fiber foods such as fried chicken, French fries, desserts, etc., may also cause hard and dry stools; long-term lack of exercise will weaken the activity of intestinal muscles and slow intestinal peristalsis, resulting in hard and dry stools; long-term medication may destroy the balance of normal intestinal flora, resulting in decreased digestive ability and excessive absorption of stool water; staying up late and irregular bowel habits may also affect intestinal peristalsis and lead to hard and dry stools.
[0003] Generally speaking, dry and hard stools are difficult to pass. Due to the effort of defecation, long-term breath holding, and increased abdominal pressure, blood return from the rectal and anal veins will be obstructed, which can easily lead to hemorrhoids over time. At the same time, dry and hard stools may scratch the skin of the anus and anal canal. In addition, the anus cannot withstand the huge tension when defecating forcefully, which can cause anal fissures. Patients will experience symptoms such as pain and blood in the stool. Therefore, when the stool is dry and hard and cannot be passed smoothly, it is necessary to seek medical attention in time, take samples for testing, and treat the symptoms.
[0004] Clinically, in order to remove samples of patients' dry and hard stool, an extractor is generally used. The extractor usually has a slender tube that can reach deep into the anus. During the removal process, it is easy to mistakenly insert it too deep into the anus, causing damage to the anus or rectum. Especially when the extractor is designed with sharp or barbed parts, the risk is higher. If it is pulled out violently, it may also scratch the mucosa of the anal canal or rectum, causing bleeding and pain. If it contains mucus or blood, the sampling part may not contain feces containing pathological components, which may easily lead to inaccurate test results. Summary of the invention

[0033] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0034] Embodiment, this embodiment discloses a dry hard stool remover, including a removal paddle 5, such as Figure 4 As shown, the removal paddle 5 is a long elastic structure, which can be made of PVC plastic material, with elasticity and support strength. The removal paddle 5 becomes thinner from the middle to the two long side walls and is bent and extended to the same side. This structure allows the removal paddle 5 to have a certain flexibility when inserted into the anus, reducing damage to the anus. The elastic structure design of the removal paddle 5 enables it to smoothly enter the anus during insertion and bend flexibly during the removal process, reducing damage to the anus and rectum. The edges and corners of the removal paddle 5 are provided with arc chamfers, which further reduce friction and pain during insertion and removal.
[0035] One short side of the removal paddle 5 is the insertion end, and the other short side is the tail end. The insertion end is used as the end for inserting into the anus, and the tail end is used as the end for medical staff to hold. A reinforcing rod 54 is fixedly inserted into the two long side walls of the removal paddle 5, and one end of the reinforcing rod 54 extends out of the tail end to form an extension end. A C-shaped spring piece 52 is transversely fixed between the ends of the two extension ends. The C-shaped spring piece 52 can be made of PVC plastic material. Figure 7 and Figure 8 As shown, the reinforcing rod 54 provides additional supporting force, so that the removal paddle 5 has sufficient strength when deformed and is not easily broken.
[0036] Holding the C-shaped spring piece 52, and squeezing the two ends of the C-shaped spring piece 52 with the thumb and index finger of one hand, the two ends of the C-shaped spring piece 52 can be deformed together. Since the removal paddle 5 becomes thinner from the middle to the two long side walls and is bent and extended to the same side, the two reinforcing rods 54 can bend the two long side walls of the removal paddle 5 together to form a C-shaped clamping cavity. The two long side walls are bent together to wrap and crush dry and hard feces. The purpose of this design is to crush and compress dry and hard feces on the one hand, which can reduce the space occupation. The deformed removal paddle 5 changes from a long sheet structure to a C-shaped structure, reducing the width occupation. In this way, it can not only wrap the crushed feces, but also be drawn out from the anus with a narrow width, making it easier to take out, while avoiding scratching the mucous membrane of the anal canal or rectum.
[0037] like Fig. 9 As shown, the removal paddle 5 is inserted through the anus, and the C-shaped spring piece is squeezed together with one hand. The two reinforcing rods 54 and the two long side walls of the removal paddle 5 are bent together to form a C-shaped clamping cavity. The two long side walls are bent together to wrap and crush the dry and hard feces, and then the feces are gently pulled out, and the dry and hard feces blocked in the anus are removed repeatedly. The design of the C-shaped spring piece 52 enables the removal paddle 5 to form a stable clamping cavity when clamping the feces, thereby effectively wrapping and crushing the dry and hard feces, ensuring the integrity and accuracy of the sampling. When the C-shaped spring piece 52 is released, the bent and deformed removal paddle 5 can be reset, and the above operation is repeated continuously to remove the dry and hard feces blocked in the anus little by little.
[0038] The most important thing is that, through the design of the two long side walls of the removal paddle 5 being close together and bent, the dry and hard feces can be broken up by using the two long side edges of the removal paddle 5 that are close together, and then compressed into the C-shaped clamping cavity. The small-scale removal method can reduce the scratching of the anal mucosa and avoid causing severe pain. At the same time, compared with the traditional digging method with barbs, on the one hand, when entering the anus, it can slowly enter by fitting the inner wall of the anus, and the cross-sectional area of entry is the area of the end of the insertion end, which is small, so the entry resistance is small. In this way, when the anus is blocked by dry and hard feces, the pain during insertion is reduced. On the other hand, the dry and hard feces are wrapped in the C-shaped clamping cavity by the method of enveloping, and there will be no falling when taking it out, so that a single effective removal can be achieved.
[0039] The above design not only improves the accuracy and safety of removal, but also reduces the pain and discomfort of the patient during the removal process, and has high clinical application value.
[0040] The present invention also discloses a segmented sampling tube for sampling stool taken out by a dry and hard stool extractor, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a sampling head, a tube cap 2 and a sealing tube 1. A sample storage cavity 11 is opened at one end of the sealing tube 1. A connecting rod fixedly connected to the inner wall of the tube cap 2 is provided at one end of the sampling spoon 21. The sample storage cavity 11 is used to store the sampling spoon 21 and the connecting rod, and the tube cap 2 is tightly sleeved with the outer wall of the sealing tube 1. When sampling, hold the tube cap 2, and use the sampling spoon 21 to dig the stool taken out of the C-shaped clamping cavity in sections, that is, multi-point sampling, that is, segmented sampling, and then put the sampling spoon 21 into the sample storage cavity 11, and then cover the tube cap 2, and temporarily seal it in the sealing tube 1 for inspection to avoid contamination and affect the accuracy of the test results.
[0041] The design of the sample storage chamber 11 not only facilitates the storage and transportation of samples, but also prevents sample contamination and leakage.
[0042] A storage chamber 12 is provided at the other end of the sealing tube 1, and the storage chamber 12 is used to store the stool extractor. The storage problem of the stool extractor is effectively solved, the contamination and loss of the extractor are avoided, and the hygiene and convenience of sampling are improved. The design of the sealing tube 1 allows the stool extractor and the sampling spoon 21 to be effectively stored separately, avoiding the contamination of the sampling spoon 21 when not in use, and also facilitating the storage and carrying of the sampling spoon 21 and the extractor.
[0043] Also includes a connecting seat 3, such as Figure 4 As shown, a connecting tube 53 is fixed at the middle position of the tail end of the removal paddle 5, and the connecting tube 53 is fixedly connected to the side wall of the end of the connection seat 3; the length of the connecting tube 53 is greater than the width of the C-shaped spring piece 52, and a gap is left between the C-shaped spring piece 52 and the connection seat 3. The function of the connection seat 3 and the connecting tube 53 is to provide a stable connection structure, so that the removal paddle 5 is more stable and fixed during use, thereby avoiding the inconvenience and risk of operation caused by the shaking or displacement of the removal paddle 5. Moreover, the length of the connecting tube 53 is designed to be greater than the width of the C-shaped spring piece 52, and a gap is left between the C-shaped spring piece 52 and the connection seat 3, so that it can be ensured that the compressed C-shaped spring piece 52 has enough space for movement during operation, so that the C-shaped spring piece 52 will not come into direct contact with the connection seat 3 when deformed, and it can be ensured that the C-shaped spring piece 52 can be deformed freely when subjected to external force, forming a C-shaped clamping cavity, which is helpful for removing dry and hard feces. Its main function is to provide a fixed point for the connecting tube 53, and also provide space for the deformation of the C-shaped spring piece 52.
[0044] For example, Figure 4 and Figure 5As shown, the connecting seat 3 is a hollow structure, and a side wall of a strip-shaped structure is provided on one side of the side facing the C-shaped clamping cavity in the middle position of the removal paddle 5. One end of the hollow expanding part 51 located at the tail end is connected to the hollow structure, and the other end is a closed structure; this design enables the hollow expanding part 51 to be connected to the hollow structure of the connecting seat 3, thereby forming a closed channel, and the surface wall of the hollow expanding part 51 is provided with a plurality of liquid holes arranged along the I-shaped structure. It also includes an extruder, which includes a rubber hollow bladder 4 with a corrugated structure. The corrugated structure design of the rubber hollow bladder 4 makes it have good elasticity and extrusion performance, and can effectively control the flow of the softener during use. One end of the rubber hollow bladder 4 is a closed structure, and the other end is connected to a guide tube 41, which is filled with softener. The guide tube 41 is fixedly connected to the end of the connecting seat 3 facing away from the connecting tube 53; the guide tube 41, the space inside the connecting seat 3 and the hollow expanding part 51 constitute a softener outlet passage. When taking out, the rubber hollow bag 4 can be squeezed, and the rubber hollow bag 4 is compressed and deformed, so that the softener filled in the rubber hollow bag 4 can be squeezed out from the guide tube 41 into the connecting seat 3, and the softener can be released at multiple points during the removal process through these liquid holes, so that the effective transmission of the softener can be achieved. The softener uses the same ingredients as the enema, and has a softening and lubricating effect, thereby softening dry and hard stools, reducing friction and damage during the removal process, and safely removing dry and hard stools to avoid damage to the anus or rectum.
[0045] The design of the hollow expansion portion 51 can further expand the contact area of the softener and improve the softening effect. The arrangement of the liquid holes allows the softener to be evenly sprayed on the stool surface, avoiding insufficient or excessive local softening caused by concentrated spraying. In this way, dry and hard stool can be softened more effectively, reducing damage to the anus and rectum during sampling.
[0046] Since the rubber hollow capsule 4 is soft in texture, it is easy to be compressed during the extrusion process. Figure 6 As shown, a guide rod 43 is fixed on the closed structure inside the rubber hollow bag 4, and the guide rod 43 is a cross structure. The guide rod 43 slides and fits with the inner wall of the guide tube 41; as long as the rubber hollow bag 4 is compressed, the guide rod 43 can be driven to slide along the axial direction inside the guide tube 41, so that the guiding support of the guide rod 43 can be used to ensure that the rubber hollow bag 4 is not compressed. By providing an extruder, the stool can be softened in real time during the process of removing dry and hard stool, avoiding the problem of difficulty in removing stool caused by the lack of softening means in traditional extractors. Therefore, the technical solution of the present application solves the problem of removing dry and hard stool while reducing the risk of damage to the patient's anus and rectum, and improving the accuracy and effectiveness of sampling.
[0047] At the same time, a sealing film 42 is provided on the inner wall of one end of the guide tube 41 close to the rubber hollow bladder 4, and a spike portion for piercing the sealing film 42 is provided at the end of the guide rod 43. Before sampling, the softener in the rubber hollow bladder 4 is in a sealed state. When in use, the spike portion of the guide rod 43 pierces the sealing film 42. At the same time, the guide rod 43 is a cross structure, which does not affect the softener flowing along the guide tube 41.
[0048] A plurality of rod bodies 31 are fixed on a side wall of the connecting seat 3 connected to the guide tube 41 and distributed circumferentially around the guide tube 41. The rod bodies 31 are bent along the radial direction toward the guide tube 41 to set a curved portion. By setting a plurality of curved portions of the rod bodies 31, when squeezing the rubber hollow capsule 4, the middle finger and the ring finger of one hand are pressed against the curved portions of the two rod bodies 31. In this way, the thumb is pressed on the outer wall of the end of the rubber hollow capsule 4 to apply force and compress, so that the softener is quickly squeezed out of the rubber hollow capsule 4.
[0049] Furthermore, the outer diameter of the connecting seat 3 is set to be equal to the inner diameter of the storage cavity 12. The purpose is to insert the removal paddle 5 into the storage cavity 12 after the defecation is taken out, and the connecting seat 3 is inserted into the storage cavity 12 to fit tightly with the inner wall of the storage cavity 12. The removal paddle 5 after the defecation is taken out can be sealed in the storage cavity 12 to avoid excessive smell, and then discarded as medical waste and processed centrally.
[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
