Primary-secondary type medical semiautomatic drainage metering device

Abstract

The invention belongs to the technical field of medical instruments and discloses a primary-secondary type medical semiautomatic drainage metering device which comprises a box, a liquid storage bag, a box liquid drain valve, a drainage mechanism and a liquid storage bag liquid drain valve. A partition overflow port is formed on the upper portion of a box cavity partition which is arranged in a box cavity, a box cover is fixed on the upper portion of the box, an air film is arranged in a deflating hole which is arranged at the left end of the box cover, a drainage liquid guide-in port is arranged at the right end of the box cover in a matched manner, large-capacity metering scale marks and precise metering scale marks are arranged on one side of the box, a liquid storage bag adapting port is fixed on the upper portion on one side the liquid storage bag, liquid storage bag scale marks are arranged on one side and along the height direction of the liquid storage bag, the box liquid drain valve comprises a valve seat, a valve sleeve, a spiral sleeve and a valve core, the drainage mechanism comprises a catheter and a transition connector, and the liquid storage bag liquid drain valve is adapted with the middle of the bottom of the liquid storage bag. The primary-secondary type medical semiautomatic drainage metering device has the advantages that cost is reduced and expense burden of the medical instruments is reduced for patients, process metering and result metering can be performed simultaneously, intensity is improved, immediate sampling is facilitated, and attending intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a mother-in-law medical semi-automatic drainage metering device, which is used in clinical medical practice to measure urine of catheterized patients so that medical staff can understand the pathological conditions of patients. Background technique [0002] Earlier, drainage bags were commonly used in medical clinics. The structure is composed of plastic tubes (also known as ground drainage tubes) and plastic urine storage bags with large-capacity measurement marks. This drainage bag can only be refined because it cannot be measured correctly. Estimate the patient's urine volume, resulting in large errors, which will affect the quality of clinical monitoring, so it is gradually eliminated. [0003] Thus, there is a urine metering reservoir of a construction similar to that disclosed in the following documents. For example: the "medical semi-automatic urine ...

Problems solved by technology

[0005] The above-mentioned CN1282451C, CN200994924Y and CN202207340U, as well as CN2778276Y (a urine storage and metering device) not mentioned above, all have the following technical problems: First, because the only hard box is used, the urine storage capacity is limited However, if the volume of the box is to be increased, it is easy to increase the cost of manufacturing and use, and the consumption of raw materials is large, which will eventually lead to an increase in the medical expenses borne by the patient; The precision measurement effect of combining the process and the result. Third, because the structure of the liquid discharge valve of the box body is unreasonable, it is easy to be damaged during the packaging, transportation and storage of the finished product, and once the liquid discharge valve is damaged, the entire device will be scrapped ; Fourth, because it does not have the function of random sampling of drainage fluid, it causes confusion for medical staff when sampling
