Description

Device for collecting and containing urine for

to analytical laboratories ".

  The subject of the invention is a device

  to collect and contain urine intended for laboratory

  analysis areas. Examination of urine is one of the most frequently performed laboratory tests This takes place in

  every time a complete picture of the

  the general clinical state of a subject or when specific conditions

  they require it, for example for the pregnancy test.

  To perform the urine examination, it is necessary to collect and transport to a laboratory a sample of the urine in question.

  to fulfill this very simple mission, there are difficulties

  important and well-known practices of those who

  are found in front of such a situation.

  In fact, it is first of all necessary to look for a clean container having reasonably small dimensions and which nevertheless presents a mouth not too small for

  that one can urinate without this becoming problematic.

  Also problematic is the search for means of closure

  appropriate container to prevent the exit, actually

Stable content.

  This research is overly painful

  and their result is most often unsatisfactory.

  The present invention aims to create a device of the type indicated for collecting and containing urine for analysis laboratories, this device avoiding the disadvantages mentioned in referring

  to devices currently in use.

  To this end, the invention relates to a

  positive type of the above type characterized in that it comprises a cylindrical container shaped test-piece, a plug having a body traversed by a first passage and a second passage, a funnel-shaped member having a mouth intended to

  from this bottom, as well as a closing element of the passages.

  The invention will be better understood with regard to

  of the following description and the accompanying drawings

  The section of passage 5 has a pre-

  determined and whose relation to the length of the passage is

  prepared to cause the formation of a stable urine meniscus

during the overturning of the container.

  The device 1 further comprises an organization

  The organ 9 is advantageously shaped like a funnel.

  made of plastic, for example polypropylene.

  funnel-shaped shaft 9 has a mouthpiece 10 for

  born to be associated with the first passage 5 More precisely

  the mouth 10 of the funnel-shaped member 9 is de-

  limited by a tubular portion 11 intended to be engaged to

force on the tubular part 8.

  The funnel-shaped member 9 is

  on the top wall 4a of the plug 4 by radial ribs

  reliefs generally designated 12.

  Opposite the second cylindrical passage 6, the plug 4 is provided with a thin tube 13 which is integral with the plug and made of the same material The tube 13 extends towards the bottom of the container 3 up to a predetermined distance

L of this background.

  The cap 4 is provided at its upper part with

  an annular flange 14 defining a seat 15 whose

  diameter and depth correspond to the diameter and the

  thickness of a disk 16, so that the disk 16 is

  The disc 16 thus constitutes a closing element for the passages 5 and 6. This disc 16 is made of the same material as the plug 4 and is connected to

  hinge with it by a thin flexible sail 17

  16 is provided at its center with a tubular portion 18

  to seal the tubular part

  8 when the disc 16 is inserted into the seat 15.

  For reasons that will be specified hereinafter, the mouth 10 of the funnel-shaped member is

  positioned so that when this organ is in its posi-

  With its upwardly flared upward direction -4- (see Fig. 1), this burr 10 and, consequently, the container 3, are oriented in a direction at an angle

  This angle is chosen equal to about 300.

  In addition, the funnel-shaped member 9 has a crushed shape along its flanks so as to

  to be flattened along a vertical plane of symmetry, this plane

  at an angle P with the vertical plane passing through the axis of the

  This angle P is chosen to be about 30.

  The cylindrical container 3 has a bottom portion, designated 19, having a narrowed section and

  provided with radial stiffening ribs 20.

  The outer shape of the cylindrical container

  3, and in particular its total length and section, are chosen to allow the use of this container in a

  conventional laboratory centrifuge.

  The operation of the device according to the invention is described below with reference to an initial condition shown in FIG. 1. The subject, man or woman who is to be subjected to the urine test, takes the device according to the invention. invention and arranges it as shown in Fig. 1, so that the funnel-shaped member

  The funnel-shaped device is easy to use on a ladies' bidet seized and handled by the container. The urine passes from the funnel 9 into the container 3 through the mouth 10 and the passage 5, while a corresponding volume of air leaves the container 3 through the thin tube 13, the annular groove 7 and the interval that the ribs 12 hold between the upper wall 4 has the

  cap 4 and the funnel-shaped member 9.

  -5- When level 2 has urine 2 in the

  black container 3 is stopped The container 3 is thus filled

  exactly the amount of urine you want.

  At this moment, the user reverses the dis-

  positive by transferring the remaining urine on the bottom of the organ 9 in the form of funnel During this operation, the urine can not leave the container 3 through the formation of a meniscus

  After the excess urine has been thrown away,

  the user separates the funnel-shaped member 9 from the recess

  green as needed, simply by removing the cap 4,

  without implying the removal, even involuntary, of

that 16.

  Thanks to its external shape, the reservoir

  can be mounted directly on the centrifuge.

  During the analyzes, the sediments are deposited on the bottom of the container 3, in the tubular part

19 with narrowed section.

  The main advantages of the device according to the invention are that it is fast to use, easy to close and eliminates all the operations of tranvasement This device also ensures the quick and easy taking of urine according to the exact amount necessary in the laboratory. -6-
