Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer for medical clinical tests, and more particularly to a timer for medical clinical tests for measuring erythrocyte sedimentation rate, which is capable of sequentially and continuously measuring a large number of time values.

Erythrocyte sedimentation rate measurement measures the rate at which red blood cells in blood injected into a specified glass tubule descend within 1 and 2 hours, and is considered an essential testing method in medical clinical diagnosis. Erythrocyte sedimentation rate measurements in hospitals and clinics are generally performed at 10 times a day.
Up to 50 people are tested, and in cases such as mass testing, more than 100 people are often tested in a day.

Since such a large number of tests are usually performed in conjunction with other medical work, using a conventional clock or a single timer has the drawback of requiring great care. Currently, there is also a multi-timer (multi-tone minute clock) for clinical testing as a compound timer. Measures the passage of time by rotating the . However, when this type of timer is used for measurement tasks such as erythrocyte sedimentation rate measurement, which is relatively simple but requires many consecutive repetitions, it requires a large number of pins and requires insertion operations. It has the drawback that it is complicated to use due to the narrow work involved, and it is cumbersome and difficult to use for measuring erythrocyte sedimentation rate.

This invention involves attaching a plurality of timepieces in parallel to a main shaft rotating at a constant speed, which are loosely fitted when not measuring, can be crimped during measurement, and can rotate integrally with the main shaft, and are equipped with notification switches corresponding to the timepieces. They are arranged side by side, and when each timer stick reaches the timekeeping position as the main shaft rotates, the timer stick presses the alarm switch to close the circuit, and corresponds to the rotatable position of the timer stick. A timer for medical clinical testing that is suitable for medical clinical testing, particularly for measuring erythrocyte sedimentation rate, which eliminates the above drawbacks by providing a timer for medical clinical testing characterized by having a storage case with a notch attached externally to the main shaft. The purpose is to provide

In FIG. 1, which shows a partially cutaway perspective view of an embodiment of the present invention, and FIG. 2, which shows an enlarged view of part A in FIG. be. In this embodiment, the driving force motor 1 is used, but a spring or other method may be used. 2 is the motor rotation axis. 3 is a main shaft connected to the motor rotating shaft 2; The main shaft 3 is made of a lightweight tube made of aluminum, synthetic resin, or the like, and the outer circumferential surface of the main shaft 3 may be covered with an elastic material such as rubber or sponge, or may have an uneven surface. 4
is a timepiece, which includes a cylinder 5 having a threaded through hole approximately in the center extending from the outer diameter to the inner diameter, and a pin having one end screwed into the through hole and a knob 7 formed at the other end. It is formed to be rotatable integrally with the main shaft 3 by loosely fitting into the main shaft 3 when not measuring, and by pressing the tip 8 of the screw of the knob body 7 against the main shaft 3 during measurement. Although the tip 8 is not pointed in FIG. 2, it may be pointed.

The clock stick 4 has 1, 2, and 3 on the knob part of the head, respectively.
Record the numbers of ... and attach any number of rods, such as 10 to 30, in parallel, corresponding to the glass tube for the erythrocyte sedimentation measuring rod to be measured on the main shaft 3. Further, as shown in FIG. 3, the timekeeping rod 4 includes a cylindrical body 5 having a through hole formed approximately in the center from the outer diameter to the inner diameter, and a small hole formed on the outer peripheral surface of the cylindrical body 5 corresponding to the through hole. A cylinder 9, a pin body 6 that is slidably fitted into the small cylinder 9, has a tip 8 at one end and a knob body 7 at the other end, and connects the small cylinder 9 and the knob body 7. The spring 10 may be formed to loosely fit onto the main shaft 3 when not measuring, and to be rotatable integrally with the main shaft 3 by pressing the tip 8 of the screw of the knob body 7 against the main shaft 3 during measurement. Next, as shown in FIG. 4, the timepiece 4 consists of a hairpin body 13 consisting of a bent part 11 that engages with the outer peripheral surface of the main shaft 3 and a cylindrical body 12 having an inner diameter smaller than the outer diameter of the main shaft 3. During measurement, the cylindrical body 12 loosely fits onto the main shaft 3 and slides in the direction of the main shaft 3 during measurement, thereby connecting the hairpin body 13 and the main shaft 3.
It may also be formed so that it can be rotated integrally with the main shaft 3 by being crimped together. 14 and 15 are notification switches;
4 is a flexible conductor, and 15 is a fixed continuous conductor. Flexible conductor 14 and fixed continuous conductor 1
5 are spaced apart from each other by about 0.5 to 10 mm, and are arranged in parallel to each other, substantially parallel to the axial direction of the main shaft 3, and having substantially the same length as the main shaft. In this embodiment, the fixed continuous electrical conductor 15 is composed of one piece, but it may be composed of two or more fixed electrical conductors parallel to each other. The flexible conductor 14 is made of stainless steel, steel, copper, or other conductive and elastic coil springs. Fixed continuous conductor 1
5 is a rod-shaped body or thin plate made of stainless steel, steel, copper, or other conductor. The flexible continuum 14 and the fixed continuous conductor connect with bell, buzzer, chime, and lamp circuits. Reference numeral 16 denotes a storage case made of plastic, which extends from the motor 1 to the other end bearing portion 17 having a bearing, and is externally installed on the main shaft 3 cylindrical body 5, the flexible conductor 14, the fixed continuous conductor 15, etc. Storage case 16
In FIG. 1, the side surface is semicircular, but the side surface may be substantially triangular as shown in FIG. 1
Reference numeral 8 denotes notches, which are formed in the storage case 16 in correspondence to the rotatable positions of the timepieces 4 and corresponding to the number of timepieces 4. A time scale 19 is provided on the outer periphery of the spindle storage case 16 to indicate the time required from when the timer 4 is crimped to the spindle 3 to when a notification such as a buzzer, bell, chime lamp, etc. is issued. Reference numeral 20 denotes a lamp, which is installed at the top of the storage case 16 in FIG. 5, but it can be installed at any location.

Therefore, in this embodiment, by aligning the timepiece 4 with an appropriate scale 19 and rotating the knob 7, the tip 8 engages with the elastic material or irregularities on the outer circumferential surface of the main shaft 3, and the timepiece 4 is moved to the main shaft 3. Crimp. Therefore, the timer 4 rotates together with the main shaft 3, and after a predetermined time has elapsed, the timer 4 rotates with the flexible conductor 1.
4 and further rotates in the same direction, the flexible conductor 14 is pressed against the fixed continuous conductor 1.
5, and a circuit such as a bell, buzzer, chime, lamp, etc. is activated to notify the measurer of the passage of a predetermined time.

Furthermore, if the timepiece rod 4 and the main shaft 3 are left without being crimped, the timer rod 4 will continue to rotate together with the main shaft 3, and the timer rod 4 will press the flexible conductor 14 and the fixed continuous conductor 15. Continuing, since the flexible conductor 14 is made of a coil spring, the flexible conductor 1
4 absorbs the pressing force of the time clock 4 while deforming as a spring, and continues to contact and press the fixed continuous conductor 15, during which time a circuit such as a bell continues to function and make a ringing sound. However, when the pressure between the timepiece rod 4 and the main shaft 3 is released, the contact pressure between the flexible conductor 14 and the timepiece rod 4 is released, and the deformation of the flexible conductor 14 is restored by the restoring force of the coil spring. When configured in this way, the structure is simpler and cheaper than installing independent switches according to the number of clock rods 4, and the ringing of the alarm can be heard without destroying the switches. It is possible to continuously measure multiple different lengths of time.

FIG. 6 shows a first timer for medical clinical examinations equipped with a flexible conductor 14 and a fixed continuous conductor 15.
Another embodiment of the figure B section is shown. In this embodiment, the fixed continuous conductor 15 is formed by alternately forming a plurality of conductor parts 21 and a plurality of elastic non-conductor parts 22.
The conductor portion 21 is made of the outer peripheral surface of a thin rod or plate made of stainless steel, steel, copper, or the like. Elastic nonconductor portion 22
is an insulating material such as vinyl or rubber with a thickness of 0.1 to 3 mm on the outer circumferential surface of the conductor portion 21 at the intersection with the direction of rotation in which the clock rod 4 rotates by being crimped with the main shaft 3.
For example, it is made by covering a small vinyl tube. Therefore, the elastic non-conductor 22 prevents the unavoidable contact between the flexible conductor 14 and the fixed continuous conductor 15 when there is no contact between the timekeeping rod 4 and the flexible continuous conductor 14, and the bell, Buzzer, chime, lamp, etc. circuits do not work.

Since this invention has the configuration and operation described above, when this invention is used to measure the erythrocyte sedimentation rate, the medical clinical test timer according to the invention is installed in front of the blood sedimentation table, and the timer corresponds to the number of the blood sedimentation rod stand to be measured. It is extremely easy to read because it uses a numbered clock stick 4.

The size of the device and the number of timer rods can be easily adjusted to match the blood sedimentation table, and the dimensions and spacing of the knobs of the timer rods can also be adjusted to dimensions that are easy to operate. Even in busy times, accidents such as misunderstanding measurements do not occur. That is, the present invention is capable of continuously and reliably measuring multiple periods of time with simple operations, has a simple configuration, and can be manufactured at low cost without taking up much space.
