First embodiment
Fig. 1 is a schematic cross-sectional view of a liquid collection device according to a first embodiment of the present invention. As shown in fig. 1, the liquid collecting device according to the first embodiment of the present invention has a handle 1, a sampling rod 13, and an absorber 2 coated on the outer peripheral wall of the sampling rod 13, the absorber 2 including an outer layer absorber 21 and an inner layer absorber 22, the inner peripheral wall of the outer layer absorber 21 and the outer peripheral wall of the inner layer absorber 22 being bonded to each other, the density of the outer layer absorber 21 being smaller than the density of the inner layer absorber 22; the inner absorbent body 22 has radially stretchable axial insertion holes 23.
The handle 1 in the present invention is generally cylindrical and serves to provide a gripping area for the sampler to operate the liquid collection device. Of course, the handle 1 may be provided in other three-dimensional shapes for easy gripping, such as a square column.
The sampling rod 13 in the invention is preferably a cylinder, and the peripheral wall of the sampling rod is coated with the absorber 2, and can be directly or indirectly fixedly connected with the end part of the handle 1. The sampling rod 13 may be injection molded from a plastic such as polypropylene or polymethyl methacrylate. In particular, the handle 1 and the sampling rod 13 may be integrally injection molded to reduce the number of assembled parts and simplify the assembly process.
The main function of the outer absorbent body 21 according to the invention is to absorb the liquid sample and release the liquid in a subsequent test. Suitable outer absorbent densities are in the range of 0.035-0.20 g/cm 3, too high a density and too low a porosity of the outer absorbent 21 may result in insufficient liquid absorption, and a high density outer absorbent 21 may have a higher hardness and may cause discomfort to the person being sampled. When the density of the outer absorbent body 21 is too low, the outer absorbent body 21 is difficult to manufacture, and insufficient capillary force of the outer absorbent body 21 with too low a density may cause difficulty in sampling. The outer absorbent 21 is soft and has sufficient capillary force, has a high sampling speed and a large collection amount, and can easily release the collected liquid sample after radial extrusion, by selecting a proper density according to application requirements.
The main function of the inner absorbent body 22 according to the invention is to support the softer outer absorbent body 21 and to form a radially telescopic axial insertion hole 23, which allows easy assembly of the absorbent body 2 and other components of the liquid acquisition device, greatly reducing the manufacturing costs and improving the reliability of the product. The axial insertion hole 23 which can radially stretch can radially expand under the action of external force so as to increase the inner diameter of the insertion hole 23 and facilitate the insertion and assembly of the sampling rod 13. After the sampling rod 13 is assembled in place, the receptacle 23 may be radially retracted back to tightly cover the peripheral wall of the sampling rod 13, forming a tight fit.
The inner absorbent layer 22 has a density of 0.15-0.45 grams/cm 3. If the density of the inner absorbent member 22 is too low, the strength is insufficient, and the absorbent member is easily detached from the sampling rod 13. Too high a density of the inner absorbent layer 22 can result in too low a radial stretch of the receptacles to be assembled. The inner absorbent body 22 has a wall thickness of 0.2-3.5mm, and a smaller absorbent body 2 is suitable because the device is mainly used for collecting liquid samples of parts of the human body such as the mouth, nasal cavity, cervix, vagina, etc. The thinner inner layer absorber 22 wall thickness facilitates reducing the absorber diameter, facilitating the fabrication of smaller liquid acquisition devices; the larger wall thickness of the inner absorbent 22 is advantageous for increasing the strength of the inner absorbent 22, and is suitable for manufacturing applications requiring higher strength of the inner absorbent 22, such as liquid collecting devices that need to extrude the liquid collected in the absorbent 2.
According to the liquid collecting device of the present invention, the absorber 2 comprises the inner layer absorber 22 with higher density and the outer layer absorber 21 with lower density, which are both made of two-component fiber bonding, preferably two-component fiber with sheath-core structure or eccentric-core structure, such as polyethylene/polypropylene fiber, polyethylene/polyester fiber, etc., and the chemically inert polyethylene is used as the sheath of the fiber, so that the absorption of the detected component in the liquid sample can be reduced, and the sensitivity of the subsequent test can be improved. The inner wall of the outer layer absorber 21 and the outer wall of the inner layer absorber 22 are bonded to each other, and the outer layer absorber can be prevented from falling off during assembly or use.
According to the liquid collecting device of the present invention, the axial compression strength of the absorber 2 is greater than the radial compression strength. With this structure, the liquid collected in the absorber 2 can be squeezed out in a radially compressed manner.
The liquid collecting device also comprises an upper baffle 12 and a lower baffle 14 which are arranged at two ends of the sampling rod 13, and the upper baffle 12 is fixedly connected with the end part of the handle 1.
The cross-sectional area of the lower baffle 14 decreases from top to bottom, and the maximum cross-sectional area of the lower baffle 14 is greater than the inner diameter of the receptacle 23 and less than the maximum expanded inner diameter of the receptacle 23.
In order to simplify the assembly process and reduce the cost, the handle 1, the sampling rod 13, the upper baffle 12 and the lower baffle 14 are integrally formed in this embodiment, and preferably injection molding is adopted. The absorber 2 is used for absorbing liquid to be detected, and the absorber 2 is provided with an axial jack which can be radially stretched, and the cross section of the lower baffle 14 decreases from top to bottom, so that the maximum cross section of the lower baffle 14 is larger than the inner diameter of the jack 23 and smaller than the maximum expanded inner diameter of the jack 23. Preferably, the cross section of the lower end of the lower baffle 14 is set smaller than the cross section of the insertion hole 23 in the inner layer absorber 22, when the lower baffle 14 is inserted into the insertion hole 23 of the inner layer absorber 22, the insertion hole 23 is radially opened, so that the lower portions of the lower baffle 14 and the sampling rod 13 can smoothly pass through the insertion hole 23, and after the lower baffle 14 completely passes through the insertion hole 23, the insertion hole 23 is radially retracted. Since the maximum cross section of the lower baffle 14 is larger than the cross section of the insertion hole 23, the absorber 2 cannot escape from the lower baffle. After the liquid sample is sampled, the liquid sample can be directly used for subsequent testing.
The cross section of the lower baffle 14 is preferably circular or a polygon of approximately circular shape. The longitudinal section of the lower baffle 14 is preferably trapezoidal, circular arc or the like. In the present embodiment, the lower baffle 14 is provided with a trapezoidal longitudinal section.
Second embodiment
Fig. 2 is a schematic cross-sectional view of a liquid collection device according to a second embodiment of the present invention. The present embodiment is similar to the first embodiment in structure, and the same parts as those of the first embodiment are not described in detail in the description of the present embodiment.
As shown in fig. 2, in the liquid collecting device of the present embodiment, the front end of the absorber 2 is formed in a spherical crown shape, the wall thickness of the inner layer absorber 22 is 0.2mm, and if the strength of the inner layer absorber 22 needs to be increased, the wall thickness of the inner layer absorber 22 can be increased appropriately. The liquid collection device of the embodiment is suitable for collecting samples at human body parts with smaller space and more sensitivity. Such as nasal, cervical, vaginal, etc.
In the liquid collecting device of this embodiment, an indicating component 3, such as a protonic color-changing test paper, is disposed between the upper end of the absorber 2 and the upper baffle 12, so that the collecting state of the absorber on the liquid sample can be observed in real time during sampling, so as to be convenient for judging whether the sample collection is completed.
In the present embodiment, the longitudinal section of the lower baffle 14 is provided in a circular arc shape.
Third embodiment
Fig. 3 is a schematic cross-sectional view of a liquid collection device according to a third embodiment of the present invention. The present embodiment is similar to the first embodiment in structure, and the same parts as those of the first embodiment are not described in detail in the description of the present embodiment.
As shown in fig. 3, this embodiment is similar to the first embodiment. The liquid collection device of this embodiment is used for collecting saliva in the oral cavity for drug abuse detection, the density of the outer layer absorber 21 is about 0.08 g/cm 3, the density of the inner layer absorber 22 is 0.35 g/cm 3, and the wall thickness is 1.5mm, so that the inner layer absorber 22 has higher strength. In the present embodiment, the lower baffle 14 is provided with a trapezoidal longitudinal section.
In the present embodiment, in the process of manufacturing the absorber 2, the fiber arrangement direction may be controlled so that the axial compressive strength of the absorber 2 is greater than the radial compressive strength.
Fig. 4 is a schematic structural view of a liquid collecting container which is matched with a liquid collecting device of a third embodiment of the present invention. As shown in fig. 4, when the absorber 2 absorbs enough liquid, a mating liquid collecting container 4 as shown in fig. 4 is inserted, and the handle 1 is pressed down so that the absorber 2 is radially compressed, thereby squeezing the liquid in the absorber 2 into the liquid collecting container 4.
In particular, as shown in fig. 4, the liquid collecting container 4 used in cooperation with the liquid collecting apparatus shown in fig. 3 includes a liquid collecting chamber 41, and a compressing portion for radially compressing the absorber 2 disposed in the liquid collecting chamber 41. The compression portion includes a conical inlet 42, a radial compression chamber 43 provided at a lower portion of the inlet 42, and a liquid discharge port 44 provided near a boundary between the inlet 42 and the radial compression chamber 43. The liquid discharge port 44 communicates with the liquid collection chamber 41. The diameter of the upper baffle plate 2 is basically equal to the diameter of the absorber 2 after being fully radially compressed, the inner diameter of the radial compression cavity 43 is slightly larger than the diameter of the absorber 2 after being fully radially compressed, and the maximum cross-sectional diameter of the lower baffle plate 14 is smaller than the diameter of the absorber 2 after being fully radially compressed. The upper baffle 12 is provided with a large strength so as to press the absorber 2 into the liquid collection container 4.

In the radial compression chamber 43, the absorber 2 is sufficiently radially compressed, and the absorbed liquid is sufficiently released and flows into the liquid collection chamber 41 through the liquid discharge port 44, thereby completing the liquid collection work. The collected liquid sample was used for subsequent detection.
