Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to the manufacturing of medical, surgical and veterinary instruments. Background Art
[0002] At present, when medical units such as hospitals conduct fecal tests, for the sampling of dry feces and liquid feces, the current sampling form is to use a rod-shaped sampling rod for dry feces and a dropper for liquid feces, with two sampling devices. For example, the Chinese patent with the publication number CN220124717U discloses a body fluid sample collection device, providing the following technical solution. The utility model discloses a body fluid sample collection device; the device includes a collection rod, a sampling progress indicating element and a sample absorber; a sample absorber is fixed to the outer end of the collection rod; the collection rod is a transparent tubular shape with an open outer end; the sampling progress indicating element is strip-shaped and installed in the inner cavity of the collection rod; the sampling progress indicating element contacts the sample absorber. In the utility model, the collection rod is set as a hollow transparent structure, and the long strip-shaped sampling progress indicating element is placed inside the collection rod; the long strip-shaped structure of the sampling progress indicating element can facilitate the user to observe its color change, so as to more clearly and accurately indicate the sufficiency of sample collection. The utility model is provided with an annular groove on the suction head installation part at the outer end of the collection rod. The annular groove can play a role in accommodating the adhesive, which helps to prevent the adhesive from flowing into and blocking the inner cavity of the collection rod during the process of bonding the sample absorber and the suction head installation part. This utility model patent well solves the problems such as easy leakage of the buffer solution and insufficient sampling amount during the fecal sampling process. However, the problem with this fecal sampler is that if the patient has liquid feces, it cannot meet the requirement of collecting enough samples, and using a dropper alone for sampling increases the cost of the dropper. Summary of the Utility Model
[0003] The purpose of the utility model is to propose a fecal sampling and detection device, which solves the problems of high cost, low efficiency and inconvenient and slow use, and achieves the purposes of low cost, high efficiency, high sampling and detection accuracy, high reliability and convenient and quick use.
[0004] To achieve the above purpose, the utility model adopts the following technical solution: A fecal sampling and detection device, characterized by comprising: a sampling device composed of a sampling rod and a soft rubber head, a sampling head is provided at the front end of the sampling rod, the end is connected to the soft rubber head, a sampling cover is provided on the outside of the connection between the sampling rod and the soft rubber head, and cavities that communicate with each other are provided inside both the sampling rod and the soft rubber head.
[0005] The advantage of this design is that the sampling head of the sampling device can improve the sampling efficiency and the amount of fecal residue. At the same time, the communicating cavity inside the sampling rod and the soft rubber head can facilitate the suction and discharge of the sample, enabling the use of only one device for collecting dry feces and liquid feces, thus improving the convenience and efficiency of use.
[0006] Preferably, the sampling head is a serrated sampling head, and a sampling hole is provided at the top. The cavity inside the sampling rod and the soft rubber head communicates with the sampling hole.
[0007] The advantage of this design is that the serrated sampling head can increase the contact area with feces, improving the sampling efficiency and the amount of fecal residue. Since liquid feces are in a flowing liquid state and are dispersed when collecting feces on paper or in the toilet, the sampling hole is designed to be close to the top and at a low height, so that even a small amount of feces can be higher than the sampling hole for sampling.
[0008] Preferably, the cavity inside the sampling rod is a sampling channel. The size of the sampling channel in the sampling head part is smaller than that in the non-sampling head part. The cavity inside the soft rubber head is an open cavity, and the sampling hole communicates with the open cavity through the sampling channel.
[0009] The advantage of this design is that the size difference of the sampling channel can facilitate the inhalation and storage of liquid feces through the soft rubber head. At the same time, the connectivity between the sampling hole and the sampling channel makes the suction and discharge of the sample smoother and more efficient.
[0010] Preferably, a sampling rod flange is provided at the end of the sampling rod, and sampling rod ribs are provided on the sampling rod flange. The soft rubber head is provided with a soft rubber head flange, and inner grooves and outer grooves are provided on the soft rubber head flange. The sampling rod flange is adapted to the soft rubber head flange, and the sampling rod ribs are snapped into the inner grooves for connection.
[0011] The advantage of this design is that the ribs of the sampling rod and the grooves of the soft rubber head cooperate. Since the soft rubber head is an elastomer, when the sampling rod is inserted into the soft rubber head, it is in a tight fit state, and a seal is formed between the soft rubber head and the sampling rod to enable sampling, and at the same time, it can prevent detachment. The flange of the sampling rod is mainly used for assembly limit to prevent the sampling rod from being inserted into the soft rubber head too long or too short during assembly, thus ensuring the consistency of assembly. The flange of the soft rubber head mainly plays a sealing role. When the sampling cap is tightened with the bottle body, a seal is formed by pressing the soft rubber head flange.
[0012] Preferably, sampling cap ribs are provided inside the sampling cap. The sampling cap is adapted to the soft rubber head, and the sampling cap ribs are snapped into the outer grooves for connection.
[0013] The advantage of this design is that the rib connection between the sampling cover and the soft rubber head can enhance the stability and sealing performance of the device, avoid sample leakage, and ensure the reliability and accuracy of sampling.
[0014] Preferably, the size of the sampling rod part inside the sampling cover is larger than that of the sampling rod part outside the sampling cover, and the size of the sampling channel inside the sampling cover is larger than that of the sampling channel outside the sampling cover.
[0015] Preferably, a sealing ring is provided at the end of the sampling rod near the sampling cover.
[0016] The advantage of this design is that the sealing ring can effectively prevent sample leakage and ensure the accuracy and reliability of sampling. The setting of the sealing ring can ensure that the sample will not leak during the sampling process and maintain the integrity and purity of sampling.
[0017] Preferably, the sampling device is adapted to be equipped with a detachable detection device.
[0018] The advantage of this design is that the combined use of the sampling device and the detection device improves the convenience and efficiency of detection. By integrating the detection device, the operation steps are reduced and the pollution risk during sample transfer is minimized, thus enhancing the reliability and accuracy of detection.
[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows.
[0020] 1. Through the design of the communicating cavity inside the sampling rod and the soft rubber head, and the combined use of the serrated sampling head and the sample suction holes, the device can effectively increase the contact area with feces and improve the sampling efficiency. This design makes it more convenient and efficient to collect dry feces and liquid feces, and different states of samples can be processed without replacing the device.
[0021] 2. Through the flange connection between the sampling rod and the soft rubber head and the rib connection design between the sampling cover and the soft rubber head, the overall stability and reliability of the device are significantly enhanced. This connection method can effectively prevent loosening and falling off during sampling, reduce the risk of sample leakage, and ensure the accuracy and reliability of sampling.
[0022] 3. By integrating the specially designed soft rubber head with the sampling rod, only one device is needed to collect dry feces and liquid feces, which improves the convenience and efficiency of use. Description of the Drawings

Detailed implementation manners
[0028] To make the objectives, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings. The proportions of the components are not drawn according to the actual proportions, and the proportions and dimensions shown in the drawings should not limit the essential technical solutions of the present utility model. These embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific embodiments described.
[0029] See Figures 1-4 As shown, a fecal sampling and detection device, characterized in that it includes: a sampling device composed of a sampling rod and a soft rubber head, a sampling head is provided at the front end of the sampling rod, the end is connected to the soft rubber head, and a sampling cover is provided outside the connection between the sampling rod and the soft rubber head, and cavities communicating with each other are provided inside both the sampling rod and the soft rubber head.
[0030] Existing fecal sampling and detection techniques, although they have to some extent solved problems such as the easy leakage of buffer solution and insufficient sampling volume during the fecal sampling process, still have many significant drawbacks and limitations. First of all, the current techniques cannot simultaneously meet the sampling requirements for both liquid feces and dry feces. The physical properties of liquid feces make the sampling process difficult, which also poses a challenge to obtaining a sufficient sample volume. In some medical situations, such as the detection and research of digestive tract diseases, the acquisition of liquid fecal samples is crucial. However, the existing sampling and detection devices do not take this into account, resulting in limitations in practical applications. Secondly, the existing sampling and detection devices require the use of a dropper for sampling separately, which undoubtedly increases the complexity of the sampling process and also increases the cost of the dropper. The cooperative use of multiple instruments not only makes the whole process cumbersome but also may affect the accuracy of the collected samples. In addition, this method also requires considering the storage and management issues of the dropper, increasing additional economic and time costs. In the existing technology, a rod-shaped sampling rod is used for sampling dry feces, while a dropper is needed for liquid feces. This means that two different sampling devices need to be used, which not only increases the cost but also reduces the work efficiency. This method also increases the risk of sample contamination when switching devices. Therefore, the objective of the present utility model is to provide a fecal collector that can be used for both dry and liquid feces with low cost, quickness, and convenience in view of these problems. The design concept of the present utility model is to adopt a device that can simultaneously handle the sampling of dry feces and liquid feces to eliminate the deficiencies of the existing technology, improve the sampling efficiency, reduce the cost, and at the same time provide a more accurate and reliable sample collection process.
[0031] As Figure 1 shown in an embodiment, Figure 1 is a schematic structural diagram of a sampling device according to an embodiment of the present utility model. The present utility model designs a fecal sampling and detection device, and its design core lies in its versatility and sealing performance, which can effectively collect dry feces and liquid feces, while ensuring the purity of the sample and preventing leakage. The device of the present utility model includes two main parts, namely a sampling rod and a soft rubber head, which are connected to each other to form an integral sampling system. The front end of the sampling rod is equipped with a serrated sampling head, and this design can effectively contact the feces and collect a sufficient sample, especially suitable for the collection of dry feces. The end of the sampling rod is connected to a soft rubber head. To ensure the sealing performance, a sealing ring is provided at one end of the sampling rod close to the sampling cover. In addition, a sampling cover is provided on the outer side of the connection between the sampling rod and the soft rubber head, and mutually communicating cavities are provided inside both the sampling rod and the soft rubber head, allowing the sample to move freely inside the device, which is suitable for the collection and transmission of liquid feces.
[0032] Such a design brings several significant benefits:
[0033] First, the serrated sampling head increases the surface area in contact with the stool, which allows even harder dry stool to be sampled effectively. The serrated edge can easily cut into the stool, making the collection process more efficient. The serrated shape also helps to retain more samples, which is particularly important for subsequent testing and analysis. Secondly, the interconnected cavity design of the sampling rod and the soft rubber head simplifies the process of sample absorption and discharge. This structural design allows stool samples to be sucked from the sampling head and temporarily stored in the cavity, reducing the risk of leakage and contamination during sample transfer. This is particularly critical for thin stool, as liquid or semi-liquid samples are more likely to leak and cause contamination. Third, the setting of the sealing ring greatly improves the sealing performance of the system. During the sampling process, especially when carrying or transporting samples, the effective seal prevents sample leakage and ensures the integrity of the sample. This not only protects the sample from external contamination, but also reduces the biosafety risks that may be posed to the operator. Finally, the integrated design of the sampling rod and the soft rubber head increases the stability of the sampling device, allowing the operator to handle the sample more easily and safely. The design of the sampling cover not only further strengthens the sealing of the device, but also provides a safe sealing environment for the samples after sampling.
[0034] In general, the design of this stool sampling and testing device fully considers the convenience, efficiency and safety of the operation. Through meticulous design thinking, the efficiency and quality of stool sample collection are significantly improved, while the difficulty and cost of operation are reduced, which helps to greatly improve work efficiency in the field of medical testing.
[0035] like Figure 2 In one embodiment shown, Figure 2 This is a cross-sectional view of a sampling device of an embodiment of the utility model. The design of a stool sampling and detection device designed by the utility model ingeniously integrates multiple functions, aiming to improve the flexibility, reliability and efficiency of sampling. The device of the utility model is composed of a sampling rod and a soft rubber head, wherein the front end of the sampling rod is designed with a serrated sampling head for effectively cutting and collecting stool samples. The sample suction hole on the sampling head, and the interconnected cavities inside the sampling rod and the soft rubber head are for facilitating the absorption and transfer of samples. The connection between the sampling rod and the soft rubber head is equipped with a sampling cover, which increases the sealing of the entire device. In terms of internal structure design, the cavity inside the sampling rod is defined as a sampling channel, and its size design shows a trend of gradually increasing from the sampling head to the end, especially the sampling channel located in the inner part of the sampling cover, which is larger than the part located outside the sampling cover, forming a structure similar to a storage cavity. In addition, a sealing ring is provided at the position of the sampling rod near the end of the sampling cover, which further enhances the sealing performance of the device.
[0036] This design has several significant benefits:
[0037] First, the serrated sampling head combined with the suction holes greatly improves the efficiency and quality of sampling. The serrated shape can easily cut into dry or sticky feces, while the suction holes facilitate sucking the collected samples into the sampling channel. This design enables the device to be applicable to fecal sampling of different natures (dry and wet), expanding the scope of application. Second, the gradually increasing design of the sampling channel, especially the formation of a structure similar to a storage cavity within the sampling cover, provides a large space for the collection and temporary storage of dilute fecal samples. This not only enables the collection of a sufficient amount of dilute fecal samples to meet the detection requirements but also reduces the possibility of sample leakage during sampling. Moreover, the design of the sampling cover and the sealing ring greatly enhances the sealing and reliability of the entire device. During sampling and sample transfer, sealing is crucial for ensuring the purity of the sample and avoiding cross-contamination. The sampling cover not only effectively protects the sample in the sampling channel but also reduces the risk of sample leakage during operation. The addition of the sealing ring further ensures a tight fit between the sampling cover and the sampling rod, thus providing double protection. In addition, this design also demonstrates a high degree of user-friendliness and operational convenience. By integrating the serrated sampling head, suction holes, and gradually expanding sampling channel, operators can sample different types of feces more easily and efficiently. Especially when a large number of dilute fecal samples need to be quickly collected to meet urgent detection requirements, the advantages of this design are particularly obvious. Therefore, a fecal sampling and detection device designed by the present utility model shows significant advantages in improving sampling efficiency and quality, ensuring the sealing and safety of samples, and optimizing the user operation experience. Through careful design and ingenious structural arrangements, it can not only meet the sampling requirements of dry and wet fecal samples of different types but also provide a more convenient and efficient operation experience while ensuring the quality and safety of samples. The innovation of this fecal sampling and detection device is of great significance and value for fecal sample collection and analysis in the fields of medical and health, disease diagnosis, etc.
[0038] As Figure 3 shown in an embodiment, Figure 3An exploded view of a sampling device according to an embodiment of the present utility model. A fecal sampling and detection device designed by the present utility model is a system composed of multiple carefully designed components, aiming to provide a simple, efficient and hygienic sample collection method. The device of the present utility model includes a sampling rod and a soft rubber head, which are connected by a precisely designed connection mechanism. The front end of the sampling rod is equipped with a serrated sampling head for cutting into and sampling feces, and the sample suction hole at its top is connected to the internal cavity to facilitate the suction of the sample. The end of the sampling rod is designed with a sampling rod flange with convex ribs, and the soft rubber head is provided with a matching soft rubber head flange with inner and outer grooves. The convex ribs on the sampling rod flange are snapped into the inner groove of the soft rubber head flange, enabling the two to be tightly and firmly connected. This connection mechanism not only ensures the stability between the sampling rod and the soft rubber head, but also facilitates their separation when needed for cleaning or component replacement. Another key part of the sampling device is the sampling cover, which is also designed with convex ribs inside, and the sampling cover is adapted to the shape of the soft rubber head, and its convex ribs are snapped into the outer groove on the soft rubber head flange, further improving the overall stability and sealing of the device. This tight combination helps prevent the collected sample from leaking during transportation or processing, ensuring the safety and purity of the sample. In addition, a sealing ring is provided at the position of the sampling rod near the sampling cover end, which enhances the sealing of the entire device in the closed state, further ensuring that no contamination or leakage occurs during sampling and transportation. The design of the interconnected cavities inside the sampling rod and the soft rubber head being connected to the sample suction hole enables liquid or semi-solid samples to be easily sucked into the internal cavity through the sample suction hole and released through the same channel when needed. This feature is very suitable for handling more fluid samples such as loose feces. In summary, a fecal sampling and detection device designed by the present utility model realizes multi-functional sampling requirements through careful design, improves the convenience of operation and the safety of the sample, and at the same time its unique connection mechanism and sealing design ensure the high efficiency of the sampling process and the reliability of the sample.

A fecal sampling and detection device includes: a sampling device composed of a sampling rod and a soft rubber head, the front end of the sampling rod is provided with a sampling head, the end is connected to the soft rubber head, and a sampling cover is provided outside the connection between the sampling rod and the soft rubber head. The inside of the sampling rod and the inside of the soft rubber head are both provided with interconnected cavities. The sampling device is adapted to a detachable detection device.
[0040] The usage method of the device of the present utility model is as follows:
[0041] 1. When collecting dry feces, insert the sampling rod into the fecal sample, and the serrated sampling head enhances the adsorption to the feces, so that the feces remain on the sampling head;
[0042] 2. When collecting dilute feces, press the soft rubber head to expel the air in the cavity of the soft rubber head. When the pressure of the soft rubber head decreases, inhale the sample. When transferring the sample to the bottle, press the soft rubber head to discharge the sample.
[0043] The utility model is not limited to the above embodiments. No matter what changes are made in its shape or material composition, as long as the structural design provided by the utility model is adopted, it is a deformation of the utility model and should be considered within the protection scope of the utility model.
