Description

Dropping funnel device with automatic exhaust function

Technical Field

The utility model belongs to medical infusion equipment, and particularly relates to a dropping funnel device with automatic exhaust.

Background

At present, in the field of infusion heating, common bubble detection and removal methods in the market are as follows: the air bubble generated by heating is temporarily stored in an exhaust drip chamber, the air detection device detects whether the air in the exhaust drip chamber reaches an alarm threshold value, if the air in the exhaust drip chamber reaches the alarm threshold value, the flow path is immediately clamped, the air bubble is manually sucked out by an exhaust valve above the exhaust drip chamber through an injector, and then the flow path is re-opened, so that the purposes of detecting and removing the air bubble are achieved. However, this method has several problems:

1. relying on manual work, the operation is time-consuming;

2. each time of exhaust needs to consume one injector, which increases the operation cost of the patient;

3. manual exhaust requires untimely manual intervention, personnel cannot leave, and the exhaust needs to be prepared at any time, so that great inconvenience is brought to nurses;

4. aspiration of air multiple times using a syringe is prone to bacterial invasion, affecting patient health.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a dropping funnel device with automatic exhaust, which can automatically exhaust air in the process of transfusion or blood transfusion.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the utility model provides a take automatically-exhausting's dropping funnel device, includes the exhaust dropping funnel, exhaust dropping funnel upper portion one side is equipped with the inlet, and the lower extreme is equipped with the liquid outlet, and the top is equipped with discharge valve, and this discharge valve is including the ventilative fungus membrane of drainage and the gas vent that is located the ventilative fungus membrane top of drainage, is equipped with the check valve on the gas vent.

The lower part in the exhaust drip chamber is provided with a blood and blood component filter covered on the liquid outlet.

The pore diameter of the filter pores of the hydrophobic breathable bacterial filter membrane is not more than 0.22 mu m.

The dropping funnel device with the automatic exhaust function has the following advantages:

1. the air exhaust valve formed by the hydrophobic breathable bacterial filtering film and the one-way valve realizes the automatic air elimination problem in the process of transfusion or blood transfusion, and reduces the labor cost;

2. by adopting the automatic bubble removal function of the utility model, the infusion efficiency in the infusion process can be effectively improved, the continuous and smooth operation of the infusion process is ensured, and powerful support is provided for avoiding the intra-operative hypothermia of a patient under the condition of high-flow infusion heating;

3. by adopting the automatic bubble removal function, bubbles can be automatically removed without using an additional injector for matching, so that the treatment cost of a patient is reduced;

4. the air vent valve and the hydrophobic and breathable bacteria filtering membrane which are opened in one direction can always keep the tightness of a flow path, avoid the risk of bacterial invasion and stop the infection risk of a patient;

5. through the blood and blood component filter at the bottom, tiny bubbles in the liquid can be filtered out and can be continuously discharged upwards after large bubbles are formed on the surface of the filter screen in a gathering way.

Drawings

The utility model is described in detail below with reference to the attached drawings and detailed description:

FIG. 1 is a schematic view of the structure of an exhaust drip chamber of the present utility model;

FIG. 2 is a schematic view of a partial (top) construction of the exhaust drip chamber of the present utility model;

FIG. 3 is a schematic perspective view of the blood and blood component filter of the present utility model.

Detailed Description

The automatic exhaust dropping funnel device is shown in fig. 1-2, and comprises an exhaust dropping funnel 1, wherein one side of the upper part of the exhaust dropping funnel 1 is provided with a liquid inlet 2, a liquid inlet pipe 3 can be connected through the liquid inlet 2, the lower end of the exhaust dropping funnel is provided with a liquid outlet 4, a liquid outlet pipe 5 can be connected through the liquid outlet 4, the top end of the exhaust dropping funnel is provided with an exhaust valve 6, and the exhaust valve 6 comprises a hydrophobic and breathable bacterial filter membrane 7 and an umbrella-shaped one-way valve 8 which is arranged radially and positioned above the hydrophobic and breathable bacterial filter membrane 7. Medical liquid flows into the exhaust drip chamber 1 through the liquid inlet pipe 3 and the liquid inlet 2, air in the medical liquid entering the exhaust drip chamber 1 automatically rises, and is firstly discharged outwards automatically by pushing the upper one-way valve 8 through the hydrophobic air-permeable bacterial filter 7 of the exhaust valve 6 (the exhaust path is shown by a dotted arrow in fig. 3). The filter pore size of the hydrophobic and air-permeable bacterial filter 7 can be selected to be nominally 0.22 μm or smaller, and can pass only air, and external bacteria cannot enter, and the check valve 8 can also function to prevent the entry of external air.

As shown in fig. 1 and 3, the lower part of the inside of the exhaust drip chamber 1 is provided with a blood and blood component filter 17 covered on the liquid outlet 4, which is in a tubular structure, the periphery is provided with a filter screen 19 spaced from the inner wall of the exhaust drip chamber 1, the upper end is closed, the inside and the lower end are communicated with the liquid outlet 4, the medical liquid flowing out can be filtered in a large area through the filter 17, and fine bubbles in the medical liquid can be filtered on the filter screen of the blood and blood component filter 17, and the fine bubbles are gathered to form large bubbles and then rise and are discharged by the exhaust valve 6. For example, the total area of the screen of the filter is not less than 10cm ² The wire diameter of the filter screen is 100+/-10 mu m, the aperture is 200+/-20 mu m, and the tissue form is single warp and single weft.

In summary, compared with the prior art, the drip chamber device with automatic exhaust has the following advantages:
