Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The vacuum urine collection cup provided in the embodiments of the present application will now be described.

Please refer to fig. 1, 2 and 3, which are schematic structural views of a vacuum urine collecting cup. The vacuum urine collecting cup comprises a cup body 1, a cup cover 2 and a liquid sucking needle 3, wherein a liquid sucking pipe 4 is arranged on the cup cover 2; the liquid suction needle 3 comprises a liquid suction nozzle 5 and a needle head 6 which are coaxially arranged, and one side of the liquid suction nozzle 5, which is close to the needle head 6, radially protrudes to form a supporting boss 7; the bottom of the liquid suction pipe 4 is provided with a contraction port 8 with the gradually reduced inner diameter for clamping the liquid suction nozzle 5, and the inner wall of the contraction port 8 is provided with a back-off 9 matched with the support boss 7.

During the assembly, the pipette tip 5 is down, puts into pipette needle 3 from pipette 4 top, and the support boss 7 of pipette needle 3 is contradicted in the top of back-off 9, then gives pipette needle 3 decurrent thrust, and the support boss 7 of pipette needle 3 is extruded and is crossed back-off 9, gets into back-off 9 below, and the bottom of pipette tip 5 is by 8 bottom centre clamps of shrink mouth that the internal diameter reduces. The reverse buckle 9 is matched with the contraction port 8 to fix the pipette tip 5 in the pipette 4, and the pipette tip 5 is partially exposed out of the bottom of the pipette 4. When in use, the arrangement of the reverse buckle 9 can also prevent the liquid suction needle 3 from being taken out when the vacuum tube is pulled out. And, when destroying after using, operating personnel only need handheld bowl cover 2, lightly hit the imbibition needle 3 and expose the part, and the support boss 7 atress of imbibition needle 3 breaks away from back-off 9 restriction, and the imbibition needle 3 can be poured out to upset bowl cover 2, accomplishes the separation of imbibition needle 3 and bowl cover 2, convenient operation, and operating personnel is difficult for receiving the pollution, clean health.

Referring to fig. 4 and 5, the reverse buckle 9 includes a middle platform 10 protruding from the inner wall of the contraction opening 8, an upper transition platform 11 connecting the upper end of the middle platform 10 and the inner wall of the contraction opening 8, and a lower transition platform 12 connecting the lower end of the middle platform 10 and the inner wall of the contraction opening 8. The advantage of transition platform 11, lower transition platform 12 in setting up is avoided because there is production error, causes the support boss 7 size of imbibition needle 3 big or little to lead to the combination of imbibition needle 3 and bowl cover 2 too loose or tension, probably lead to the imbibition needle 3 to produce the condition of rocking in pipette 4. During assembly, the supporting boss 7 of the liquid suction needle 3 firstly butts against the upper transition table 11, then moves downwards to the middle platform 10 along with the extrusion of the upper transition table 11, then enters the lower transition table 12, and finally is clamped at a proper position on the lower transition table 12.

In one embodiment, referring to fig. 5, preferably, an included angle a between the middle platform 10 and the upper transition table 11 is 10 ° to 13 °, and an included angle B between the middle platform 10 and the lower transition table 12 is 10 ° to 13 °. In the included angle range, the combination of the liquid suction needle 3 and the cup cover 2 is more stable and is not easy to shake. And on the basis of ensuring that the liquid suction needle 3 cannot be brought out by the vacuum tube, the liquid suction needle can be easily separated from the cup cover 2 after the bottom is stressed.

In one embodiment, referring to fig. 3, the inner wall of the bottom of the constriction 8 has an inner taper 13 of 6%, and the inner wall of the bottom of the liquid suction nozzle 5 has an outer taper 14 of 6%, which are tightly fitted to form a sealed structure, so as to prevent urine leakage.

In one embodiment, referring to fig. 3, a radial support block 15 is disposed below the inverted buckle 9 on the liquid suction nozzle 5, and a tightening support section 16 for holding the radial support block 15 is disposed at the middle section of the contraction opening 8. The radial supporting blocks 15 can be provided with a plurality of radial supporting blocks which are circumferentially distributed on the outer surface of the liquid suction nozzle 5; the radial support blocks 15 may also be an integral annular structure, also distributed on the outer surface of the liquid suction nozzle 5. Further, the outer diameter of the radial supporting block 15 is smaller than the outer diameter of the supporting boss 7 and larger than the outer diameter of the bottom of the liquid suction nozzle 5.

In one embodiment, the upper transition table 11 and the lower transition table 12 may be a slope or arc structure, and more preferably, referring to fig. 6, each of the upper transition table 11 and the lower transition table 12 is composed of a plurality of steps 17. That is to say, the upper transition table 11 and the lower transition table 12 are composed of a plurality of small bosses, and one boss can be better clamped with the support boss 7 of the liquid suction needle 3 with production errors to form a holding state.

Further, in one embodiment, the included angle C between the straight line of the steps 17 and the middle platform 10 is 10 ° to 13 °.

The utility model relates to an ingenious has changed the thread bonding mode of pipette 4 on imbibition needle 3 and bowl cover 2, avoids manual back-out imbibition needle 3, causes the contaminated problem of operating personnel. The liquid suction pipe 4 is provided with a supporting boss 7 protruding in the radial direction, the bottom of the liquid suction pipe 4 is provided with a contraction port 8, and the contraction port 8 is internally provided with a reverse buckle 9, so that the liquid suction needle 3 enters the reverse buckle 9 under the condition of stress and is clamped between the contraction port 8 and the reverse buckle 9. When in use, the arrangement of the reverse buckle 9 can also prevent the liquid suction needle 3 from being taken out when the vacuum tube is pulled out. And, when destroying after using, operating personnel only need handheld bowl cover 2, lightly hit the imbibition needle 3 and expose the part, and the support boss 7 atress of imbibition needle 3 breaks away from back-off 9 restriction, and the imbibition needle 3 can be poured out to upset bowl cover 2, accomplishes the separation of imbibition needle 3 and bowl cover 2, convenient operation, and operating personnel is difficult for receiving the pollution, clean health. Furthermore, the structure of the reverse buckle 9 is optimally designed, the upper transition table 11 and the lower transition table 12 are additionally arranged, and the situation that the liquid suction needle 3 shakes in the liquid suction tube 4 possibly due to the fact that the size of the support boss 7 of the liquid suction needle 3 is too large or too small due to production errors and the combination of the liquid suction needle 3 and the cup cover 2 is too loose or too tight is avoided. The upper transition table 11 and the lower transition table 12 are preferably formed by a plurality of steps 17. Namely, the upper transition table 11 and the lower transition table 12 are composed of a plurality of small bosses, and one boss can be better clamped with the support boss 7 of the liquid suction needle 3 with production errors to form a holding state.

The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present application and are intended to be included within the scope of the present application.
