Description

Multifunctional infusion set

technical field

The utility model belongs to the field of medical devices, in particular to a multifunctional infusion set, in particular to a multifunctional infusion set capable of rapid infusion of medicinal liquid and pressure monitoring, and is especially suitable for clinical departments such as first aid in operating rooms and severe cases. Emergency infusion and pressure monitoring of patients.

Background technique

Clinically, it is often necessary to monitor the patient's central venous pressure before and during the operation to determine the functional status of the peripheral circulation and cardiac pump. Continuous observation of changes in central venous pressure has important guiding significance for the treatment of shock. It is suitable for severe shock with difficulty in judging the cause; unexplained oliguria or anuria; severe water and electrolyte disorders, difficult to maintain balance; massive fluid replacement and blood transfusion.

Monitoring central venous pressure while infusion has important clinical significance. At present, central venous pressure monitoring is generally fixed on the infusion stand with a glass tube with a diameter of 0.8-1.0 cm and a ruler engraved with cmH2O or a pressure measuring tube with a scale, connected to a medical multi-channel rotary valve three-way switch and A connecting tube, one end is connected to the infusion set, and the other end is connected to the central venous catheter. This monitoring method has more consumables and requires multiple connections, which is time-consuming and laborious. In addition, the drip rate of ordinary infusion sets is relatively slow, and the infusion bag needs to be squeezed to meet the flow rate requirements during emergency infusion.

Utility model content

The technical problem to be solved by the utility model is that it is inconvenient to monitor the venous pressure during the infusion process and the ordinary infusion set cannot meet the requirements during the emergency infusion. It provides a multifunctional infusion set suitable for emergency infusion and pressure monitoring.

In order to achieve the above object, the solution adopted by the utility model is: a multifunctional infusion set, including a puncture device, a tee, a drip funnel, a flow regulator, a liquid medicine filter, and a screw joint, which are connected into one body through a catheter, and the liquid medicine A multi-channel three-way rotary valve is also arranged on the conduit between the filter and the screw joint.

Two ports of the multi-channel three-way rotary valve of the utility model are respectively connected to a liquid medicine filter and a screw joint through a conduit, and a protective cap is provided on the remaining port.

The catheter size of the utility model is 3.4mm in inner diameter and 4.8mm in outer diameter.

The puncture device of the utility model is provided with a sheath outside, and the sheath is made of PE material.

The key accessories of the catheter of the infusion set, the drip funnel and the liquid medicine filter of the utility model adopt TPE material or TOTM plasticized PVC material.

The puncture device of the utility model adopts ABS material.

The utility model is equipped with a multi-channel three-way rotary valve on the conduit between the liquid medicine filter and the spiral joint. When the central venous pressure and other pressure monitoring is required, one side port of the medical multi-channel rotary valve can be opened to connect the pressure measuring tube. For monitoring, its connection is convenient. At the same time, when needed, the multi-channel three-way rotary valve can be used for dosing, which is convenient for rapid drug administration in emergency situations. The pipeline size of the infusion set is larger than that of ordinary infusion sets, which can meet the requirements of rapid infusion during emergency infusion, without squeezing the infusion bag, saving time and effort; if there is no need for emergency infusion, the flow rate can be adjusted through the flow regulator of the pipeline , infuse according to the flow rate of the conventional infusion set. In addition, all the materials of the infusion set of the utility model adopt medical materials that do not contain DEHP plasticizers through market verification, which effectively avoids the harm of DEHP plasticizers to the human body.

Detailed ways

The main parts of the utility model multifunctional infusion device are puncturer 2, tee 5, dripping funnel 6, flow regulator 7, liquid medicine filter 8, and screw joint 10, which are connected into one body by conduit 3. The conduit between 8 and the screw joint 10 is also provided with a multi-channel three-way rotary valve 9 . The trocar 2 is provided with a sheath 1 outside. The conduit between the tee 5 and the puncturer 2 is provided with a clamp 4 for controlling the liquid in the infusion set bottle (bag) to enter the dripping funnel 6 . The intravenous infusion needle 11 is connected to the infusion pipeline through the screw joint 10, and its connection is reliable and convenient.

Two ports of the multi-channel three-way rotary valve 9 are respectively connected to the liquid medicine filter 8 and the screw joint 10 through conduits, and a protective cap 91 is provided on the remaining port. The protective cap 91 has a protective effect on the port of the multi-channel three-way rotary valve. When the port is used, the protective cap is opened to connect to a pressure measuring device or to perform emergency drug administration. It is easy to operate by setting a clamp on the conduit between the multi-channel three-way rotary valve 9 and the liquid medicine filter 8 .
