Description

Technical Field

[0001] This utility model belongs to the field of medical testing equipment technology, specifically, it relates to a stool routine collection device. Background Technology

[0002] Hospital stool routine collection devices use clean, dry, disposable collection tubes or various types of stool collection instruments. Patients collect samples into these containers, and hospital nurses manually add barcodes before sending them to the laboratory for testing. Stool routine tests typically include: color, consistency, odor, parasites, fecal occult blood (FOB), and transferrin (TF). While tests for color, consistency, odor, and parasites require judgment based on the actual stool sample and microscopic examination, tests for fecal occult blood (FOB) and transferrin (TF) use different methodologies. FOB and TF tests primarily employ colloidal gold methods, requiring a small amount of stool to be dissolved in saline solution and added dropwise for testing.

[0003] Therefore, when a patient's specimen arrives at the laboratory, in addition to performing tests on color, properties, odor, and parasites, the laboratory staff also need to manually transfer the collected stool sample to another collection tube containing saline solution for testing fecal occult blood (FOB) and transferrin (TF). During the transfer process, since the new collection tube containing saline solution does not have the patient's relevant information or barcode, the laboratory staff need to manually enter this information into the testing instrument. This process is prone to errors and mislabeling, and the opening of the tube can produce an odor, causing discomfort to the testing personnel and affecting work efficiency.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a routine stool collection device. The basic concept of the technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows:

[0006] A routine stool collection device includes a tube body, a tube cap, a sealing cap, a partition, a pressing mechanism, and a resilient pressing airbag. The top of the tube body is open, and the bottom is a drip outlet. The tube cap and the sealing cap are threaded to the top and bottom of the tube body, respectively, to seal the tube body. The partition is set on the inner wall of the tube body and divides the inner cavity into an upper cavity and a lower cavity. The upper cavity is used to hold the stool collection, and the lower cavity is used to hold physiological saline.

[0007] The pressing mechanism includes a pressing rod, the bottom end of which penetrates the tube cap and extends into the upper cavity, the top end of which and a section of the rod body are located outside the tube cap, the partition is provided with a permeable membrane, and the bottom end of the pressing rod can pierce the membrane and extend into the lower cavity; the pressing airbag is embedded in the side wall of the tube body in the lower cavity.

[0008] Furthermore, the pressure rod consists of a thick rod and a thin rod. The top end of the thick rod is connected to the pressing plate, and the bottom end is coaxially connected to the top end of the thin rod. The tube cap has an outward-facing central blind hole. The thick rod is coaxially fitted into the blind hole and slidably connected to it. The bottom end of the thin rod slides through the bottom of the blind hole and extends into the upper cavity. The membrane is coaxially arranged with the thin rod.

[0009] Furthermore, the pressing mechanism also includes a spring, which is sleeved on the thin rod, with the bottom end of the spring connected to the bottom surface of the blind hole and the top end of the spring connected to the bottom surface of the thick rod.

[0010] Furthermore, the partition plate is provided with a through hole, the membrane is connected to the bottom sidewall of the hole to seal the through hole, and a sealing plate is sleeved on the outer wall of the thin rod, the sealing plate can slide tightly inside the through hole.

[0011] Furthermore, the bottom end of the thin rod is provided with a bucket, and the outer bottom surface of the bucket is provided with a pointed tip.

[0012] Furthermore, it also includes a pressure cap, which is detachably connected to the top of the nozzle cap.

[0013] Furthermore, the compression airbag is spherical or ellipsoidal.

[0014] Furthermore, the compression airbag is made of rubber.

[0015] Furthermore, the partition is positioned at the vertical midpoint of the tube, and the volume of the saline solution does not exceed three-quarters of the lower cavity capacity.

[0016] Furthermore, the outer wall of the tube is provided with a capacity scale.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0018] This invention divides the traditional single-lumen tube into two, using a thin membrane to separate the two lumens. A puncture in the membrane connects the two lumens, combining a disposable dry sampler and a sampler containing physiological saline into one unit. This eliminates the need to replace the sampler, avoiding transcription errors. A pressing mechanism allows for rapid mixing of the sample and physiological saline within the tube, reducing discomfort for testing personnel. Furthermore, a pressing airbag enables drip dispensing, facilitating the removal of the test solution. This convenient operation simplifies procedures for laboratory staff and improves work efficiency.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0032] like Figures 1 to 3 As shown, the stool collection device described in this embodiment includes a tube body 1, a tube cap 2, a sealing cap 3, a partition 4, a pressing mechanism, a pressing airbag 9, and a pressing cap 8. The top of the tube body 1 is open, and the bottom is a drip outlet. The tube cap 2 and the sealing cap 3 are used to seal the top and bottom drip outlets of the tube body 1, respectively, and can be tightened by screwing. The partition 4 is set on the inner wall of the tube body 1 to divide the inner cavity into an upper cavity and a lower cavity. The upper cavity is used to hold the stool collection material, and the lower cavity is used to hold physiological saline 7. The upper cavity is smaller and the lower cavity is larger. Preferably, the partition 4 is set at the vertical midpoint of the tube body 1, and the volumes of the upper and lower cavities are nearly the same. The volume of physiological saline 7 in the lower cavity does not exceed three-quarters of the lower cavity's volume. Of course, this is just an example. Generally, the stool collection material is about 30-50g, and the physiological saline is about 3-5ml. The volume can be set according to actual needs.

[0033] The pressing mechanism includes components such as a pressure rod and a spring 66. The pressure rod consists of a thick rod 61 and a thin rod 62, both of which are cylindrical. Referring to the attached diagram, the top of the thick rod 61 is connected to a pressing plate 63, which is located above the pipe cap 2 at a distance. The bottom of the thick rod 61 is coaxially connected to the top of the thin rod 62, effectively transitioning from thick to thin. The pipe cap 2 has an outward-facing blind hole, which is cylindrical and coaxial with the cap 2, meaning the cap's central axis is coaxial. The thick rod 61 is coaxially fitted within the blind hole and slidably connected thereto. The bottom of the thin rod 62 slides through the bottom of the blind hole and extends into the upper cavity. The thick rod 61 slides within the blind hole, while the thin rod 62 is slidably connected to the bottom surface of the blind hole. Spring 66 is sleeved on thin rod 62. The bottom end of spring 66 is connected to the bottom surface of blind hole, and the top end of spring 66 is connected to the bottom surface of thick rod 61. Spring 66 can both hold thick rod 61 and provide rebound force when thick rod 61 is compressed. Therefore, spring 66 can be in its natural state, that is, without external force, spring 66 is only subjected to the weight of thick rod 61. Of course, limiting mechanisms can also be set. Preferably, when spring 66 is in a compressed state, a vertical slide is provided on the side wall of blind hole, and a protrusion that cooperates with the slide is provided on the side wall of thick rod 61. The protrusion is limited and guided by the slide, which can both guide the sliding and limit the movement, keeping spring 66 in a compressed state.

[0034] The partition plate 4 is provided with through holes, which are also round holes and coaxial with the thin rod 62. The film is connected to the side wall of the hole bottom to seal the through hole. A sealing plate 65 is sleeved and installed on the outer wall of the thin rod 62, and the sealing plate 65 can slide tightly in the through hole. The film is a penetrable film. When the through hole is sealed, the upper cavity and the lower cavity are independent of each other. When the film is penetrated, the upper cavity and the lower cavity can be connected. Here, the sealing plate 65 can block the through hole, that is, when the thin rod 62 moves, it will move the sealing plate 65. When it slides tightly with the through hole, the hole can be sealed, separating the upper and lower cavities and making them independent of each other. The film here can be a plastic film, which can not only achieve the purpose of sealing but also be convenient to pierce. In addition, in order to facilitate sampling with the thin rod 62, a digging bucket 64 is provided at the bottom end of the thin rod 62. The outer bottom surface of the digging bucket 64 is provided with a pointed head. The digging bucket 64 is conducive to sampling, and the pointed head can facilitate piercing the film.

[0035] In the initial state of the collector, the pressing cap 8 is screwed to the top end of the pipe mouth cover 2 and covers the thick rod 61 and the pressing plate 63. As shown in the attached drawing, the pipe mouth cover 2 is provided with a flange and is generally in the shape of a Chinese character 'Shen'. The part below the flange is screwed to the pipe body 1, and the part above the flange is screwed to the pressing cap 8. Here, the flange can not only facilitate the screwing of the pipe mouth cover 2 but also make the collector applicable to an automatic labeling machine. When labeling, the flange can make the collector be stuck for machine labeling. When the patient collects a sample, there is no need to press the thick rod 61 part, and the pressing cap 8 can play a protective role to avoid accidental touch. When the patient uses it for sampling, the pipe mouth cover 2 (with the pressing cap 8) is unscrewed from the pipe body 1, and the digging bucket 64 of the thin rod 62 is used to sample the stool. After sampling according to the relevant sampling operation method, the sample is stored in the upper cavity. Then the pipe mouth cover 2 is covered back and tightened for sealing, and then the collector can be sent to the inspection collection place. After the patient's specimen enters the laboratory, when the staff in the testing department operates, the pressing cap 8 is unscrewed, the pressing plate 63 is pressed down, the digging bucket 64 will pierce the film and bring the sample into the lower cavity. Due to the rebounding force of the spring 66, it can be pressed multiple times to bring a sufficient amount of sample into the lower cavity. When the physiological saline 7 in the lower cavity is mixed with the sample, it needs to be shaken evenly. At this time, it is necessary to keep the lower cavity separated from the upper cavity, and the tight fit between the sealing plate 65 and the partition plate 4 ensures the independent sealing of the lower cavity. As a preference, a clamping mechanism (not shown in the attached drawing) is provided on the pressing plate 63 and the pipe mouth cover 2. When it is necessary to shake and mix after pressing, the clamping mechanism can make the two be clamped to keep the upper and lower cavities independent, or a mechanism similar to a pressing pen. The purpose is to keep the position of the sealing plate 65 unchanged when shaking and mixing. It should be noted that the clamping mechanism and the pressing pen, etc. are all commonly used structures in the prior art. Here in this example, only their applications are given, and the specific structures are not described in detail here.

[0036] An elastically recoverable pressure bladder 9 is embedded in the side wall of the lower chamber tube 1. The pressure bladder 9 can be made of rubber or silicone, with rubber being preferred. The tube body 1 is generally made of a rigid material. The pressure bladder 9 is spherical or ellipsoidal and is embedded in the side wall of the tube body 1. When the bladder is squeezed, it increases the pressure inside the chamber, which, in conjunction with the drip nozzle, achieves the effect of a dropper. Two pressure bladders 9 can be provided, which conforms to the pinching action of two fingers when performing a dripping operation. The setting of the pressure bladder 9 enables a dropper-like operation, facilitating the dripping of the mixture in the lower chamber. Moreover, the size of the bladder can be set according to needs, determining the amount of mixture dripped with each squeeze. In addition, when the chamber is sealed, the bladder can act as a buffer chamber to accommodate small fluctuations in the pressure inside the chamber. Preferably, the outer wall of the tube body 1 is provided with a volume scale, which can be used as a measurement reference for both the upper and lower chambers.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
