Patient body fluid collecting and metering device

Abstract

The invention discloses a patient body fluid collecting and metering device, and belongs to the technical field of medical equipment. The patient body fluid collecting and metering device comprises a liquid collecting bag body, a drainage mechanism matched with the liquid collecting bag body and a liquid discharging mechanism matched with the liquid collecting bag body. The patient body fluid collecting and metering device is characterized in that a patient body fluid drainage inlet is reserved on the upper portion of one side of the drainage mechanism, a patient body fluid drainage outlet is reserved on the lower portion of the side of the drainage mechanism, and the drainage mechanism comprises a liquid drainage cup seat, a liquid drainage cup, a liquid drainage pipe and a transition joint; and the liquid discharging mechanism comprises a liquid discharging pipe seat, a liquid discharging pipe, a liquid discharging valve and a liquid discharging valve limit seat. The patient body fluid collecting and metering device has the advantages that medical staff can be facilitated to grasp body liquid discharging amount of a patient in unit time accurately, and doctors can be facilitated to give a prescription to the patient or adjust therapeutic schedules; the patient body fluid collecting and metering device is convenient to manufacture, seal effect is improved, and leakage can be avoided; surrounding environment can be free of influence and affection; and the medical staff can be facilitated to sample for laboratory analysis.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a patient body fluid collection and metering device. Background technique [0002] The aforementioned patient body fluids such as urine and thoracoabdominal drainage fluid, etc., take the urine collector material for collecting patient urine as an example, which can be seen in large numbers in open Chinese patent documents, such as CN1282451C (medical use) for example. Semi-automatic urine metering storage), ZL02123886.3 (medical semi-automatic urine metering storage), ZL91225245.6 (disposable metering plastic urine bag), ZL94242826.9 (disposable precision metering double-chamber urine drainage device), ZL97211613 .3 (a bottle for measuring urine accumulation), ZL99209573.5 (urination measuring bottle), ZL01225226.3 (urine bag with accurate measurement) and ZL01268645.X (urine meter), etc. Take the equipment for collecting drainage fluid of patients after ...

AI Technical Summary

Problems solved by technology

[0004] Not limited to the patient body fluid collection devices listed above generally have the following disadvantages: First, because the liquid discharge valve cannot be matched with a metering device such as a metering pump, it affects the medical staff's accurate grasp of the patient's body fluid volume, and ultimately affects the patient's medication. Therapeutic effect, because there is a causal relationship between the doctor's medication and the degree and volume of the patient's fluid discharge, although there are scale lines on the bag body, there are often large errors in observation with the scale line; A part of the drain valve tube bundle, so the drain valve usually hangs and extends out of the edge of the bag, so it is vulnerable to damage to the drain valve in links such as packaging, transportation and storage, and also interferes with surrounding objects during clinical use The third is that the drainage pipeline and the liquid discharge valve are usually combined in the bag body production process, so not only the production is troublesome, but also there is a risk of leakage due to poor sealing and cooperation; the fourth is that there is no medical staff for A component that randomly samples a patient's body fluid for testing, so it is troublesome to take a small sample of body fluid
