Description

Technical Field

[0001] This utility model relates to a urine collector and belongs to the technical field of medical auxiliary devices. Background Technology

[0002] In clinical urine testing, both the initial and midstream urine samples play a crucial role in disease diagnosis and bacterial culture. However, current urine collection devices struggle to accurately and conveniently separate and collect the initial and midstream urine. Common collection methods have several drawbacks, such as relying on manual experience to differentiate collection stages, which is prone to errors and leads to inaccurate test results; existing collection devices are complex in structure, difficult to operate, and inconvenient for patients to use independently. Therefore, developing a device that is simple in structure, easy to operate, and can accurately separate and collect urine is of significant practical importance.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a urine collector that solves the problems of complex structure and difficult operation of urine collection devices in the prior art.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A urine collector includes a urine collection bottle and a urine collection funnel;

[0007] The urine collection funnel is fixed above the urine collection bottle by a detachable connection, and the urine collection funnel is equipped with a diversion component and an air guide tube;

[0008] The diversion assembly includes at least one separator, which is disposed at the bottom of the urine collection funnel and has at least one diversion gap communicating with the urine collection bottle and the urine collection funnel;

[0009] One end of the air guide tube passes through the diversion assembly and extends into the urine collection bottle, while the other end is connected to the outside to balance the air pressure inside and outside the urine collection bottle.

[0010] When the urine level in the urine collection bottle contacts the bottom of the air duct, the pressure difference prevents the urine from continuing to flow into the urine collection bottle through the diversion gap.

[0011] The present invention is further configured such that: the separator includes a baffle plate, a flow-dividing gap is formed between the two baffle plates, a cut is provided on one side of the baffle plate, and the cuts on the two adjacent baffle plates are respectively provided on both sides.

[0012] The present invention is further configured such that: the distance between two adjacent baffles in the diversion assembly is 10-20mm, and the area of ​​the cut is 40mm². 2 Up to 300mm 2 .

[0013] The present invention is further configured such that the cut shape of the baffle is one of a circle, a rectangle or an arc.

[0014] The present invention is further configured such that: the top of the urine collection funnel is provided with a lateral leak for guiding the middle section of urine to flow out to the outside.

[0015] The present invention is further configured such that the lateral leak and the air guide tube are spaced apart by a 90° arc in the circumferential direction of the urine collection bottle.

[0016] The present invention is further configured such that the detachable connection is a threaded connection, and the connection is provided with a sealing structure.

[0017] The present invention is further configured such that an annular protrusion is fixedly connected to the inner wall of the urine collection funnel.

[0018] The present invention is further configured such that the urine collection bottle and the urine collection funnel are made of transparent material, and the urine collection bottle is marked with a capacity scale.

[0019] The present invention is further configured such that the volume ratio of the urine collection funnel to the urine collection bottle is in the range of 1:2 to 1:4.

[0020] The beneficial effects of this utility model are:

[0021] 1. When urination begins, the initial urine flows through the reverse-positioned baffle in the diversion assembly, forming a laminar flow path and steadily flowing into the urine collection bottle along the diversion gap. At this time, the air duct maintains pressure balance, ensuring smooth urine flow. When the liquid level in the urine collection bottle rises to contact the bottom of the air duct, the urine seals the lower end of the air duct. At this point, the pressure difference between the external atmospheric pressure and the pressure inside the bottle acts on the diversion gap, creating resistance to the fluid and preventing subsequent urine from flowing further into the urine collection bottle. The middle stage of urine remains in the urine collection funnel under air pressure, achieving staged collection without cross-contamination.

[0022] 2. The baffle design of the diversion component, along with the 90° circumferential distribution of the air tube and side leak nozzle, prevents flow exchange during midstream urine drainage. This design eliminates the need for manual switching by the user; even non-professionals can complete sample separation through natural urination, significantly reducing operational complexity.

[0023] 3. The urine collection bottle and funnel are made of transparent material and have precise graduation markings on the bottle, allowing medical staff to directly observe the initial urine collection volume and determine in real time whether the sample meets the testing standards;

[0024] 4. The threaded connection structure is designed to ensure a tight seal, eliminating the risk of leakage between the urine collection funnel and the urine collection bottle, and facilitating high-temperature sterilization after disassembly;

[0025] 5. The annular ridge has a semi-circular cross-section. When the urine collection funnel is subjected to external pressure, the annular ridge, through its geometric rigidity, evenly distributes the stress throughout the entire wall of the urine collection funnel, avoiding localized deformation. For example, during high-temperature sterilization or threaded tightening, the annular ridge can effectively counteract the longitudinal bending moment caused by thermal expansion or mechanical torque.

[0026] 6. The flared shape at the top of the urine collection funnel matches the curvature of the web between the thumb and index finger of an adult's hand. When the user holds it, the thumb and index finger naturally fit into the edge of the flared shape, maintaining a stable grip even in wet and slippery environments. Attached Figure Description

[0032] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0033] like Figures 1-4As shown, a urine collector includes a urine collection bottle 1 and a urine collection funnel 2. The urine collection funnel 2 is detachably connected to the top of the urine collection bottle 1. Both the urine collection bottle 1 and the urine collection funnel 2 are made of transparent material, and the urine collection bottle 1 is marked with volume graduations 3. The volume ratio of the urine collection funnel 2 to the urine collection bottle 1 ranges from 1:2 to 1:4. The transparent material of the urine collection bottle 1 and the urine collection funnel 2, along with the precise graduations on the bottle, allows medical personnel to directly observe the initial urine collection volume and determine in real time whether the sample meets the testing standards.

[0034] Preferably, the detachable connection is a threaded connection, and the connection point is equipped with a sealing structure (not shown in the figure), such as a sealing ring. The threaded connection structure ensures that there is no risk of leakage between the urine collection funnel 2 and the urine collection bottle 1, and facilitates high-temperature sterilization after disassembly. An annular protrusion 4 is fixedly connected to the inner wall of the urine collection funnel 2. The cross-section of the annular protrusion 4 is semi-circular. When the urine collection funnel 2 is subjected to external pressure, the annular protrusion 4 distributes the stress evenly to the entire wall of the urine collection funnel 2 through its geometric rigidity, avoiding local deformation.

[0035] The urine collection funnel 2 is provided with a diversion component 5 and an air guide tube 6. The diversion component 5 includes two separators, which are located at the bottom of the urine collection funnel 2 and have at least one diversion gap 8 connecting the urine collection bottle 1 and the urine collection funnel 2.

[0036] The separator includes baffles 7, and two baffles 7 cooperate to form a flow-dividing gap 8. The spacing between two adjacent baffles 7 in the flow-dividing assembly 5 is 10-20mm, and the area of ​​the cut 9 is 40mm². 2 Up to 300mm 2 A cutout 9 is provided on one side of the baffle 7. The cutout 9 of the baffle 7 is circular, rectangular, or arc-shaped. The cutouts 9 on two adjacent baffles 7 are respectively located on both sides.

[0037] The air delivery tube 6 is fixedly connected to the side wall of the urine collection funnel 2. One end of the air delivery tube 6 passes through the diversion assembly 5 and extends into the urine collection bottle 1, while the other end is connected to the outside to balance the air pressure inside and outside the urine collection bottle 1. When the urine level in the urine collection bottle 1 contacts the bottom end of the air delivery tube 6, the pressure difference prevents the urine from continuing to flow into the urine collection bottle 1 through the diversion gap 8.

[0038] The urine collection funnel 2 has a side leak 10 at the top to guide midstream urine outwards. The side leak 10 and the air duct 6 are spaced at a 90° arc around the circumference of the urine collection bottle 1, and the side leak 10 and the cut 9 of the top baffle 7 are spaced at a 180° arc around the circumference of the urine collection bottle. The air duct 6 and the side leak 10 are circumferentially distributed at 90° to prevent flow exchange during midstream urine drainage. The cut 9 and the side leak 10 are circumferentially distributed at 180° to prevent urine from flowing out between the baffles 7 during midstream urine drainage.

[0039] The implementation principle of this utility model is as follows:

[0040] When urination begins, the initial urine flows through the reverse-positioned baffle 7 cut 9 in the diversion assembly 5, forming a laminar flow path, and steadily flows into the urine collection bottle 1 along the diversion gap 8. At this time, the air duct 6 maintains pressure balance, ensuring smooth urine flow. When the liquid level in the urine collection bottle 1 rises to contact the bottom of the air duct 6, the urine seals the lower end of the air duct 6. At this point, the pressure difference between the external atmospheric pressure and the pressure inside the bottle acts on the diversion gap 8, creating resistance to the fluid and preventing subsequent urine from flowing further into the urine collection bottle 1. The middle stage of urine remains in the urine collection funnel 2 under the action of air pressure, achieving staged collection without cross-contamination.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
