Description

Quantitative dropper

This creation is about a quantitative dropper, especially a quantitative dropper with anti-overflow structure.

In major medical institutions and regional clinics, urine examination is one of the commonly performed inspection items, as an important diagnosis basis for clinicians. However, the urine collection process is quite inconvenient for patients. When collecting urine, the patient must first collect the discharged urine in the container, and then carefully pour it into the slender collection test tube. This process often contaminates the hand due to urine leakage or urine Inadvertently spilling out of the tube for collection and inspection results in the inability to obtain a sufficient amount of urine samples, especially for the elderly and patients with hands that are prone to tremor. Therefore, the urine extraction process needs to be improved.

In order to ensure that the collected urine can be poured into the collection test tube, a sampling cup with a beak tip on the market replaces the general paper cup, and the cup body edge is provided with a pointed groove, which is easy to align the collection test tube and pour urine liquid. However, in order to reduce the cost of materials, the height of the sampling cup at the tip of the bird’s beak is usually only half of the average paper cup. When the user is collecting urine discharged from the body, urine overflow often occurs and contaminates the hand. In addition, due to the test tube The tube diameter is small, and it is still difficult to avoid leakage of urine when pouring urine, and it is not easy to control the amount of urine poured.

In order to solve the problem of urine overflowing into the collection test tube, some medical units will provide a dropper to transfer the urine in the paper cup to the collection test tube to reduce the contamination of the hand. However, the general dropper capacity is small (generally about 3 mL), and it usually takes many times to collect enough urine specimens to the collection test tube, so it is often impossible to complete the pipetting at once, and although the dropper is attached There are scales, but because the dropper is too small, the scale is not clear, so it can not be clearly interpreted to quantify.

In addition, there is another automatic urine dispensing device that can transfer the patient's urine to the collection test tube, that is, the automatic urine dispensing device automatically absorbs the urine in the general paper cup and transfers the liquid to the collection test tube, and the patient does not need to Pour urine into the collection test tube on your own to improve the problem of accidentally overturning the urine to cause insufficient urine volume or contaminated hands. However, the price of automatic urine dispensing equipment is quite expensive and does not meet the cost considerations.

In view of the shortcomings of the conventional urine collection method that need to be improved, the creator of this case believes that it is necessary to design a quantitative dropper, which has the function of overflowing excess liquid. When the user draws excessive urine, the urine will not be quantitative The orifice of the dropper overflows and contaminates the user's hand, and excess urine will be stored in the liquid storage bladder, which does not prevent the quantitative dropper from quantifying.

That is, this creation provides a quantitative dropper, including a suction ball, a tube body and an overflow prevention part. Wherein, the tube system is arranged under the suction ball, the tube body includes a certain scale and a nozzle at the bottom end of the tube body; the overflow prevention part is arranged between the suction ball and the tube body, Or the upper position of the tube body, the overflow prevention part includes a first tube neck, a second tube neck and a liquid storage bladder; wherein, the first tube neck is in communication with the suction ball and the liquid storage bladder, or The suction tube is connected with the tube body; the second tube neck is connected with the liquid storage bladder and the tube body, and the second tube neck is arranged at a relative horizontal position of the maximum scale of the quantitative scale.

In a preferred embodiment, the scale volume of the quantitative scale is 5 to 20 mL.

In a preferred embodiment, the scale volume of the quantitative scale is 5 mL.

In a preferred embodiment, the scale volume of the quantitative scale is 11 mL.

In a preferred embodiment, the total length of the quantitative dropper is 17 to 23 cm.

In a preferred embodiment, the total length of the quantitative dropper is 18 to 21 cm.

In a preferred embodiment, the tube body further includes an upper tube body and a lower tube body, wherein the lower tube body is located below the upper tube body and the bottom is the nozzle, and the lower tube body occupies the tube The length of the body is 1/5 to 1/2, and the diameter of the lower pipe body is smaller than that of the upper pipe body.

In a preferred embodiment, the lower tube has an inverted cone shape.

In a preferred embodiment, at least 1/2 of the height of the liquid storage space of the liquid storage bladder is lower than the height of the second neck.

Compared with the conventional technology, the quantitative dropper of this creation is convenient for the user to transfer urine into the collection test tube, so as not to contaminate the hand, only a small number of aspirations are needed to complete the transfer of the urine sample to the collection test The test tube is accurate, and the scale is clearly visible due to the long body of the quantitative dropper.

In this embodiment, the pipetting step of the quantitative dropper 100 includes: first pressing the suction ball 10 to expel the gas therein, and while keeping the suction ball 10 pressed, place the nozzle 201 in the The liquid to be sucked is contained under the surface of the urine in the urine cup; then, the suction ball 10 is loosened, so that the urine is sucked into the tube body 20; finally, the quantitative dropper 100 is moved to be filled In the urine collection test tube, align the mouth 201 with the collection test tube, and then press the suction ball 10 again to discharge the urine in the tube body 20 into the collection test tube. The quantitative dropper 100 is easy to operate and prevents urine from contaminating the user's hand. In addition, as shown in FIG. 3, since the second neck 302 is set at a relative horizontal position of the maximum scale of the quantitative scale 202, when the urine is drawn into the urine 4 of the tube body 20 to be transferred, the urine When the amount exceeds the maximum scale of the quantitative scale 202 (as shown in the example 5mL shown in FIG. 3), the excess urine 5 will overflow to the reservoir sac 304 via the second neck 302, that is, the fluid sac 304 can be avoided Excess urine 5 exceeds the quantifiable scale volume range of the quantitative dropper 100, so that the quantitative dropper 100 can accurately control the amount of urine in the tube body 20, and make the urine that is finally discharged into the collection and testing test tube Desired volume. That is to say, the quantitative dropper 100 of this creation has the overflow prevention part 30, so that it can prevent overflow, and the quantitative is accurate.

Please refer to Figures 4, 5, 6 and 7, which are the oblique side view, front view and schematic diagram of the quantitative method (1) and (2) of the quantitative dropper according to the second embodiment of this creation.

In this embodiment, the quantitative dropper 200 includes a suction ball 10, a tube body 20, and an overflow prevention part 30. Wherein, the tube body 20 is arranged below the suction ball 10, the tube body 20 includes a certain scale 202 and a nozzle 201 at the bottom end of the tube body; the overflow prevention part 30 is arranged in the tube body In the upper position of 20, the anti-overflow part 30 includes a first tube neck 301, a second tube neck and 302 a liquid storage bag 304; wherein, the first tube neck 301 communicates with the suction ball 10 and the tube body 20; the second neck 302 is connected to the reservoir 304 and the body 20, and the second neck 302 is set at the relative horizontal position of the maximum scale of the quantitative scale 202, as shown in Figures 6 and 7 It is shown that the second neck 302 is at a relative horizontal position with a maximum scale of 5 mL of the quantitative scale 202.

In this embodiment, the pipetting step of the quantitative dropper 200 includes: first pressing the suction ball 10 to expel the gas therein, and while keeping the suction ball 10 pressed, place the nozzle 201 in the The liquid to be sucked is contained under the surface of the urine in the urine cup; then, the suction ball 10 is released to allow the urine to be sucked into the tube body 20; finally, the quantitative dropper 200 is moved to be filled In the urine collection test tube, align the mouth 201 with the collection test tube, and then press the suction ball 10 again to discharge the urine in the tube body 20 into the collection test tube. The quantitative dropper 200 is easy to operate and prevents urine from contaminating the user's hands. In addition, as shown in FIGS. 6 and 7, since the second neck 302 is disposed at a relatively horizontal position of the maximum scale of the quantitative scale 202, when the urine 4 to be transferred into the tube body 20 is drawn When the urine volume is greater than the maximum scale of the quantitative scale 202 (as shown in the example 5mL shown in FIGS. 6 and 7), excess urine 5 will overflow to the reservoir 304 via the second neck 302, which is the reservoir The capsule 304 can prevent the excess urine 5 from exceeding the quantifiable scale volume range of the quantitative dropper 200, so that the quantitative dropper 200 can accurately control the amount of urine in the tube body 20, and finally discharged into the collection test tube Urine is the desired volume. That is to say, the quantitative dropper 200 of this creation has the overflow prevention part 30, which can prevent overflow, and the quantitative is accurate.

In this creation, the quantitative dropper 100 and 200 are used to pipette urine samples, that is, the urine in the urine container is quantitatively moved to the collection test tube. In addition, the quantitative droppers 100 and 200 of this creation can also be used to pipette other liquids, such as liquid drugs, blood, etc., that is, without causing the quantitative dropper 100 and 200 or the liquid sucked to deteriorate, This creation does not limit the liquids that the quantitative dropper 100 and 200 are used for pipetting, which is described here first. The quantitative dropper 100 and 200 can be integrally formed, the material of which is general medical plastic equipment, such as polyethylene, polyvinyl chloride, polymethyl methacrylate, polyethylene, silicone, polyester polymer, Polytetrafluoroethylene or polyurethane, etc., and this creation is not limited to these, among which polyethylene is preferred, which has the advantage of low cost.

In this creation, the quantitative scale 202 is the quantitative scale for the quantitative dropper 100 and 200, which can be set on the outer side of the tube body 20, and this creation is not limited.

In this creation, the scale volume mentioned is the volume for the quantitative dropper 100 and 200 for quantitative use, not the overall volume of the tube body 20. Specifically, when the scale capacity of the quantitative dropper 100 and 200 is 5 mL, the tubes 20 of the quantitative dropper 100 and 200 can have integers of the scale of 1 to 5, respectively, that is, the quantitative range can be 1 to 5 mL, can be used to quantify to 1 mL, 2 mL, 3 mL, 4 mL or 5 mL.

In this creation, the scale volume of the tube 20 is 1 to 20 mL, such as 1 mL, 2 mL, 3 mL, 4 mL, 5 mL, 6 mL, 7 mL, 8 mL, 9 mL, 10 mL, 11 mL, 12 mL, 13 mL, 14 mL, 15 mL, 16 mL, 17 mL, 18 mL, 19 mL or 20 mL, but this creation is not limited to this range; and, the scale capacity of the tube 20 is better 5 to 20 mL, more preferably 5 mL or 11 mL. Since the universal urine collection test tube has a capacity of 12 mL (approximately 10 mL is sufficient for inspection during collection), the appropriate urine collection volume is 10 to 12 mL, and 11 mL is preferred. Therefore, when the maximum scale volume of the quantitative dropper 100 and 200 of this creation is 11 mL, only a pipette can be used to draw enough urine; similarly, when the maximum volume of the quantitative dropper 100 and 200 of this creation is The scale volume is 5 mL, and only two operations are needed to draw enough urine. Therefore, the quantitative dropper 100 and 200 of this creation can overcome the conventional technology. The quantitative dropper has a small capacity (about 3 mL), which requires Defects caused by inconvenient operation and inaccurate dosage due to multiple pipetting.

In this creation, the total length of the quantitative dropper 100 and 200 is 17 to 23 cm, such as 17 cm, 17.5 cm, 18 cm, 18.5 cm, 19 cm, 19.5 cm, 20 cm, 20.5 cm, 21 cm, 21.5 cm, 22 cm, 22.5 cm or 23 cm, but this creation is not limited to these ranges; the total length of the quantitative dropper 100 and 200 is preferably 18 to 21 cm. The total length of the quantitative dropper 100 and 200 in this creation is convenient for the user to take and hold the quantitative dropper 100 and 200 in operation. In addition, the quantitative droppers 100 and 200 of this creation have a relatively long and narrow shape, so that the liquid sucked in fully exerts surface tension and adhesion to the wall of the tube. At the same time, with the help of atmospheric pressure, the liquid is not easy to overflow out of the tube.

In this creation, as shown in Figures 3, 6 and 7, at least 1/2 of the height of the liquid storage space of the liquid storage capsule 304 is lower than the height of the second neck 202, when the quantitative dropper 100 And when 200 absorbs urine exceeding the maximum scale of the quantitative scale 202, the excess urine 5 can overflow and be stored in the reservoir 304. If the height of the liquid storage space of the liquid storage capsule 304 is higher than that of the second tube neck 202, the space of the excess urine 5 that the liquid storage capsule 304 can store is too little.

Please refer to Figure 8, which is a schematic diagram of the appearance of the tube body 20 as shown in the figure:

In this creation, the tube body 20 includes an upper tube body 20A and a lower tube body 20B; wherein, the lower tube body 20B is located below the upper tube body 20A and the bottom is the nozzle port 201, and the lower tube body 20B accounts for The length of the tube 20 is 1/5 to 1/2 of the length, and the diameter of the lower tube 20B is smaller than the diameter of the upper tube 20A. As shown in FIG. 8(A), the length of the lower tube 20B accounts for about 1/2 of the length of the tube 20; as shown in FIG. 8(B), the length of the lower tube 20B accounts for about 20 of the tube 1/4 of the length. Further, as shown in FIG. 8(B), the shape of the lower tube 20B is preferably an inverted cone, that is, the closer to the nozzle 201, the smaller the diameter of the lower tube 20B. Due to the small diameter of the lower tube 20B, the liquid sucked into the tube body 20 is less likely to overflow out of the tube due to capillary action.

In summary, the quantitative dropper of this creation facilitates the user to transfer urine from the urine cup into the collection test tube, so as not to contaminate the hand, and only requires a small number of pipetting times to collect the required urine test The body volume makes the urine collection process more user-friendly, and the urine sample collection volume is more accurate, avoiding the situation of oversampling or undersampling.

The above has made a detailed description of this creation, but the above is only one of the preferred embodiments of this creation, but it cannot be used to limit the scope of the implementation of this creation, that is, all equals to the patent application of this creation Changes and modifications should still fall within the scope of this patent.
