Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pathological specimen liquid collection device. Background Art

[0002] In the field of modern medicine, the collection of pathological specimens is a crucial process, which is directly related to the accuracy and efficiency of pathological diagnosis. The traditional pathological specimen collection device usually includes a specimen liquid storage bucket and a bucket cover, and the bucket cover is designed with a pressing structure to collect the liquid by pressing. Although this design is simple, there are some significant problems in practical application.

[0003] This pressing structure performs poorly in terms of sealing and stability, and is prone to leakage or contamination of the specimen fluid, which not only affects the accuracy of liquid collection, but may also pose a threat to the safety of the operator.

[0004] In addition, the traditional push-type barrel cover is also limited in the speed of liquid extraction. Due to its design limitations, the liquid extraction process is usually slow and cannot meet the needs of fast and efficient pathological specimen processing. This is particularly inefficient when dealing with a large number of specimens, which seriously affects the overall process and timeliness of pathological diagnosis.

[0005] The disclosure of the above background technology content is only used to assist in understanding the concept and technical solution of the utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Utility Model Content

[0006] The present application provides a pathological specimen liquid collection device, which is used to solve the problems of poor sealing, poor stability and low liquid collection efficiency of traditional pathological specimen liquid collection devices.

[0007] In order to achieve the above purpose, this application adopts the following technical solutions:

[0008] A pathological specimen liquid collection device comprises: a specimen liquid storage barrel, a hose, a water pump, and a siphon tube. The specimen liquid storage barrel comprises a barrel body and a barrel cover, and the barrel cover is detachably connected to the bottle mouth of the barrel body; a first through hole and a second through hole are opened on the top surface of the barrel cover; one end of the hose is penetrated through the first through hole and extends into the barrel body, and the connection between the hose and the first through hole is sealed; the input port of the water pump is sealed and connected with the other end of the hose, and the water pump has a water outlet pipe; one end of the siphon tube is penetrated through the second through hole and extends into the barrel body, and the connection between the siphon tube and the second through hole is sealed; the siphon tube has a siphon ball, and a one-way valve is arranged in the siphon ball. The one-way valve is used for external air to enter the barrel body through the siphon tube to prevent the air inside the barrel body from flowing out.

[0009] In the embodiment of the present application, when the water pump starts to operate, a low-pressure area is generated inside the hose, forming a negative pressure to extract liquid. The one-way valve allows external air to enter the barrel through the siphon to prevent the air inside the barrel from flowing out. In this way, a vacuum can be prevented from forming inside the barrel, and the barrel structure can be prevented from being damaged by the vacuum. It ensures that external air can enter when the liquid is extracted, and prevents the internal air from flowing out when the liquid is not extracted, thereby avoiding the leakage of irritating odors and improving the sealing and stability of the liquid extraction. In addition, the rapid extraction of the water pump increases the liquid extraction speed, meeting the needs of efficiently processing a large number of specimens.

[0010] In some possible implementations, the barrel body is a transparent member, so that it is convenient to observe the liquid level in the barrel body and adjust the position of the siphon tube so that the siphon tube is located above the liquid level.

[0011] In some possible embodiments, the barrel body and the barrel cover are detachably connected by threaded engagement. In this way, the structure is simple, and it is easy to assemble, clean and maintain.

[0012] In some possible implementations, the water pump has an operating table, and an electronic button is arranged on the upper surface of the operating table. In this way, the electronic button can be used to control the water pump, thereby improving the convenience of operation.

[0013] In some possible implementations, the water outlet pipe is made of stainless steel, which can improve the durability and safety of the water outlet pipe and reduce the risk of pollution caused by pipeline corrosion. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1 The embodiment of the present application discloses a pathological specimen liquid collection device, including: a specimen liquid storage barrel 1, a hose 3, a water pump 2, and a siphon 4. The specimen liquid storage barrel 1 includes a barrel body 11 and a barrel cover 12, and the barrel cover 12 is detachably connected to the bottle mouth of the barrel body 11; the top surface of the barrel cover 12 is provided with a first through hole and a second through hole; one end of the hose 3 is passed through the first through hole and extends into the barrel body 11, and the connection between the hose 3 and the first through hole is sealed. Exemplarily, the connection between the hose 3 and the first through hole can be sealed by heating a sealant, an O-ring seal, or a crimping connection.

[0022] The input port of the water pump 2 is sealed and connected to the other end of the hose 3, and the water pump 2 has a water outlet pipe 22; one end of the siphon tube 4 is inserted into the second through hole and extends into the barrel body 11, and the connection between the siphon tube 4 and the second through hole is sealed and connected; the connection between the siphon tube 4 and the second through hole can be designed with reference to the connection between the hose 3 and the first through hole, which will not be repeated here. The siphon tube 4 has a siphon ball 41, and a one-way valve is arranged in the siphon ball 41. The one-way valve is used for external air to enter the barrel body 11 through the siphon tube 4 to prevent the air inside the barrel body 11 from flowing out.

[0023] Among them, when the water pump 2 starts to operate, a low-pressure area is generated inside the hose 3, forming a negative pressure to extract liquid. The one-way valve allows external air to enter the barrel body 11 through the siphon 4, preventing the air inside the barrel body 11 from flowing out. In this way, it is possible to prevent the formation of a vacuum inside the barrel body 11 and prevent the structure of the barrel body 11 from being damaged by the vacuum. Ensure that external air can enter when extracting liquid, and prevent internal air from flowing out when not extracting, thereby avoiding the leakage of irritating odors and improving the sealing and stability of liquid extraction. In addition, through the rapid extraction of the water pump 2, the liquid extraction speed is increased, meeting the needs of efficiently processing a large number of specimens.

[0024] See also Figure 1 In some embodiments, the barrel body 11 is a transparent member. For example, the barrel body 11 may be an acrylic member. Of course, the present application is not limited thereto. In other embodiments, the barrel body 11 may also be a polycarbonate member or a polyethylene member. In this way, it is convenient to observe the liquid level in the barrel body 11 and adjust the position of the siphon tube 4 so that the siphon tube 4 is located above the liquid level.

[0025] In some embodiments, the barrel body 11 and the barrel cover 12 are detachably connected by threaded engagement. In this way, the structure is simple, easy to assemble, and easy to clean and maintain.

[0026] In some embodiments, the water outlet pipe 22 is a stainless steel part. In this way, the durability and safety of the water outlet pipe 22 can be improved, and the risk of pollution caused by pipeline corrosion can be reduced.

[0027] See also Figure 1 On the basis of any of the above embodiments, the water pump 2 has an operating table, and the upper surface of the operating table is provided with an electronic button 21. In this way, the electronic button 21 can be used to control the water pump 2, thereby improving the convenience of operation.

[0028] When in use, the medical staff opens the specimen bag and places it at the outlet pipe 22 of the water pump 2. By operating the electronic button 21 on the water pump 2, the amount of formalin liquid extracted from the barrel 11 is controlled to ensure that the specimen tissue is properly soaked. After the extraction is completed, the water pump 2 is closed and the specimen bag is sealed, which effectively reduces the volatilization of formaldehyde and protects the medical staff from irritation.

[0029] To sum up, the pathological specimen liquid collection device disclosed in the embodiment of the present application mainly controls the liquid collection through the electronic button 21. The specimen liquid flows directly into the specimen bag at a uniform speed through the pipeline, and the risk of specimen liquid spilling is reduced. In addition, there is no need to perform traditional liquid collection operations such as removing the cover and pressing during the liquid collection process, which effectively avoids the contact between the specimen liquid and medical staff. After the liquid collection is completed, the device is closed and the mouth of the specimen bag is directly tightened, which effectively reduces the volatilization and flow of formaldehyde in the air, thereby reducing the irritation to the eyes and nasopharynx of medical staff, and effectively reducing the harm of the specimen liquid to medical staff. The liquid collection process is more convenient and quick, and the dosage is better controllable. While improving work efficiency, it can also effectively reduce resource waste.

[0030] The above describes the utility model and its implementation methods, which is not restrictive. What is shown in the full text is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
