SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a subcutaneous negative pressure drainage device to solve the technical problem of the subcutaneous drainage method using an empty needle to extract accumulated fluid.

The subcutaneous negative pressure drainage device comprises a negative pressure container, a measuring pot and a remaining needle, wherein the lower end of the negative pressure container is provided with a first switch valve; the lower end of the metering kettle is connected with the upper end of the negative pressure container through a first pipe section, and the upper end of the metering kettle is connected with the indwelling needle through a second pipe section; a second switch valve is arranged on the first pipe section; a flow sensor is clamped outside the second pipe section, and a flow regulating valve is also arranged on the second pipe section;

the subcutaneous negative pressure drainage device also comprises a third pipe section, one end of the third pipe section is connected with the upper end of the metering kettle, the lower end of the third pipe section is connected with the first pipe section, and a third switch valve is arranged on the third pipe section.

Furthermore, a check valve is arranged at one end of the second pipe section connected with the metering kettle.

Further, the second pipe section is connected with the indwelling needle through a threaded joint.

The utility model has the beneficial effects that:

1. the subcutaneous negative pressure drainage device of the utility model utilizes the negative pressure container to provide drainage pressure difference, and utilizes the remaining needle to replace a disposable puncture needle, thereby greatly reducing puncture times and causing little harm to patients; can realize continuous drainage and timely discharge hydrops, and is favorable for wound healing of patients.

2. The subcutaneous negative pressure drainage device has the advantages that the drainage speed can be measured by the flow sensor and can be adjusted by the flow adjusting valve, so that medical staff can conveniently adjust the drainage speed according to the set total drainage amount and drainage time, and the operation convenience of drainage work is improved.

3. According to the subcutaneous negative pressure drainage device, the volume scales are arranged on the metering kettle, so that the volume of drainage liquid discharged into the negative pressure container can be conveniently recorded, and the check valve is arranged at the inlet end of the metering kettle, so that the liquid in the metering kettle cannot flow back, and the pollution caused by backflow can be avoided.

Detailed Description

The utility model is further described below with reference to the figures and examples.

As shown in the figure, the subcutaneous negative pressure drainage device comprises a negative pressure container 1, a first switch valve 2 arranged at the lower end of the negative pressure container, a measuring pot 3 and a remaining needle 4, wherein scales for measuring the volume of drainage liquid are arranged on the measuring pot, and a suspension band 5 is also arranged on the measuring pot; the lower end of the measuring pot is connected with the upper end of the negative pressure container through a first pipe section 6, and the upper end of the measuring pot is connected with the indwelling needle through a second pipe section 7; a second switch valve 8 is arranged on the first pipe section; the second pipe section is externally clamped with a flow sensor 9, and is also provided with a flow regulating valve 10. The flow sensor can be a clamp type flow sensor in specific implementation, and the clamp type flow sensor can be reused, so that cost can be saved.

The subcutaneous negative pressure drainage device also comprises a third pipe section 11, one end of the third pipe section is connected with the upper end of the metering kettle, the lower end of the third pipe section is connected with the first pipe section, and a third switch valve 12 is arranged on the third pipe section.

In this embodiment, the first switch valve, the second switch valve and the third switch valve have the same structure, and each of the first switch valve, the second switch valve and the third switch valve includes a valve body 13, a cylindrical valve core 14, a valve core rubber sleeve 15 and a handle 16, the valve body is provided with an inlet and an outlet which are opposite to each other, the valve core rubber sleeve is fixed outside the cylindrical valve core, the valve core rubber sleeve and the cylindrical valve core are provided with valve holes 17 which are radially communicated, the valve core rubber sleeve and the cylindrical valve core penetrate through the valve body and are in running fit with the valve body, the valve core rubber sleeve plays a role in sealing and can prevent drainage fluid from leaking, and the handle is fixed on the end of the cylindrical valve core. When the handle is rotated to enable the valve hole to be opposite to the inlet and the outlet on the valve body, the switch valve is opened; when the handle is rotated to make the valve hole and the inlet and the outlet on the valve body dislocated, the switch valve is closed.

This embodiment subcutaneous negative pressure drainage device hangs drainage container and measurement kettle in the bedside through the suspender during use, presss from both sides flow sensor on the second pipeline section, then will keep somewhere the needle puncture to subcutaneous drainage portion, opens the third ooff valve again and makes and form the negative pressure in the measurement kettle, utilizes the negative pressure drainage. The flow adjusting method in the drainage process comprises the following steps: the drainage flow is calculated according to the set drainage amount and the drainage time, then the drainage flow is adjusted through the flow adjusting valve, and the flow sensor is observed, so that the actual drainage flow is consistent with the drainage flow obtained through calculation. In the drainage process, when the volume in the metering kettle rises to a certain degree, the first switch valve can be opened, and drainage liquid in the metering kettle is discharged into a negative pressure container with larger volume below for storage; the volume data of the drainage fluid discharged each time can be conveniently recorded through the scales on the metering pot so as to be convenient for reference of doctors.

Subcutaneous negative pressure drainage device in this embodiment, the puncture injury that causes patient is few, can drainage in succession, in time gets rid of the hydrops, is favorable to patient's wound healing, and the control drainage volume that can be more accurate can reduce medical staff work load.

As an improvement to the above, a check valve 18 is arranged at the end of the second pipe section connected with the measuring pot, and the check valve can prevent the drainage liquid in the measuring pot from flowing back and prevent reverse flow pollution.

As a modification to the above, the second tube section is connected with the retention needle through the threaded joint 19, and the retention needle in the modification can be separated from other parts of the subcutaneous negative pressure drainage device, so that when the first puncture fails, the retention needle can be replaced to puncture again, and other parts of the subcutaneous negative pressure drainage device do not need to be discarded, thereby saving the cost.
