Problems solved by technology

The existing problems of this instrument are: first, the body fluid flowing out from the catheter is easy to stick to the wall of the liquid receiving tube, so the liquid drop may not just fall on the electrode seam, resulting in inaccurate counting; The size of the droplet is not easy to control, so the droplet may pass through the gap (the droplet is too small) or no longer drip after connecting the electrode gap (the droplet is too large), causing it to be impossible to count; However, when counting a very small amount of body fluid experiment, the scale is too thick, so it cannot be accurately quantified; fourth, the socket of the liquid receiving tube is connected to the atmosphere, and it is not sealed, and it is easy to volatilize when there is little body fluid

Embodiment 1

[0012] like figure 2 As shown, a device for quantitative counting of body fluids includes a liquid receiving vessel 5, a liquid receiving tube 2 and a diameter-expanding part 3 of the liquid-receiving tube, an internal thread at the upper end of the liquid-receiving vessel and an external thread at the lower end of the expanding part of the liquid-receiving tube Axial docking; positive and negative electrodes are provided in the cavity of the expanded diameter part 3 of the liquid receiving tube, respectively, and electrically connected to the terminal posts 10 arranged symmetrically in the diameter direction outside the upper end of the expanded diameter part of the liquid receiving tube. The liquid receiving pipe 2 is an inverted circular truncated structure, and the nozzle at the lower end of the circular pedestal communicates with the inner cavity of the enlarged diameter part of the liquid receiving pipe. The positive and negative electrodes include the first electrode wi...

Embodiment 2

[0015] like figure 2 As shown, the device of the present invention also includes an intermediate pipe 12, the upper end of the intermediate pipe is an internal thread, which can be axially connected with the external thread of the enlarged diameter part 3 of the liquid receiving pipe; Axial connection. The lower end of the inner cavity of the intermediate tube is provided with a bracket 15, which can be used to place measuring cups of different ranges when performing counting of a small amount of body fluid, and can accurately read the capacity, thus overcoming the inability to accurately quantify a small amount of body fluid due to the fact that the scale 7 of the liquid receiving vessel is too thick Shortcomings.

Embodiment 3

[0017] On the basis of Embodiment 2, another improvement of the present invention is that a cover 13 is provided at the upper end nozzle of the round table of the liquid receiving tube. volatilization; when opened, the drainage catheter can be easily inserted. It is also possible to have a gap 11 along the generatrix of the round platform on the circumference of the nozzle at the upper end of the liquid receiving tube, and when the cover 13 is closed, the drainage catheter can be inserted from the gap.

[0018] The working principle of the device of the present invention is: after the drainage catheter is inserted into the nozzle (or gap 11) at the upper end of the round table of the liquid receiving tube 2, the body fluid flows out from the catheter, and drops onto the droplet guide 14 through the lower end of the round table of the liquid receiving tube 2. , and is guided to the axial distance between the first electrode wire 4 and the second electrode wire 8, the positive a...

Abstract

The invention discloses a device for quantitatively counting body fluid, comprising a liquid receiving vessel, a liquid receiving tube and a hole enlargement part of the liquid receiving tube, wherein the liquid receiving vessel is axially connected with the hole enlargement part of the liquid receiving tube in a detachable manner; the inner cavity of the hole enlargement part of the liquid receiving tube is provided with a positive electrode and a negative electrode which are electrically connected to a binding post which is symmetrical to the outboard diameter direction of the upper part ofthe hole enlargement part of the liquid receiving tube. The invention is characterized in that the liquid receiving tube is an inverted round table structure; the pipe orifice at the lower part of the round table is communicated with the inner cavity of the hole enlargement part of the liquid receiving tube; the positive electrode and negative electrode comprise a first wire electrode and a second wire electrode which pass through the axial center line; an axial spacing is reserved between the first wire electrode and the second wire electrode, wherein the lower end of the first wire electrode is connected with the binding post outside the upper end of the hole enlargement part of the liquid receiving tube in a V-shaped manner; the upper end of the first wire electrode is provided with a liquid drop conductor which is just arranged below the pipe orifice at the lower end of the liquid receiving tube; the upper end of the second wire electrode is connected with another binding post outside the upper end of the hole enlargement part of the liquid receiving tube; and the lower end is opposite to the center of the bottom of the liquid receiving vessel.

Description

technical field [0001] The invention relates to a quantitative counting instrument, in particular to a quantitative counting device for sweat, urine, gland fluid, bile and other body fluids in medical experiments. Background technique [0002] At present, in the field of medical research, the accuracy of medical experiments on animals is becoming higher and higher, and there is no accurate and standard method for quantitative counting of sweat, urine, glandular fluid, bile and other body fluids in functional experiments. Body fluid test counting and quantitative instruments such as figure 1 As shown. It includes the liquid receiving vessel, the liquid receiving pipe and the enlarged diameter part of the liquid receiving pipe. The liquid receiving vessel is connected with the enlarged diameter part of the liquid receiving pipe through threads. Two relatively curved positive and negative electrodes (connected to the terminal on the outer side of the upper end of the extension...
