Detailed Description

In order to explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following embodiments are described in detail with reference to the accompanying drawings.

An infusion apparatus for measuring central venous pressure, as shown in fig. 1, comprises a disposable infusion apparatus, the disposable infusion apparatus comprises a bottle stopper puncture outfit 11 for connecting a liquid medicine bag, a drip cup 12, a flow regulator 13, a spiral connector 14, a connecting pipeline 15 and a branch pipeline 21 arranged on the disposable infusion apparatus, the branch pipeline 21 is provided with the bottle stopper puncture outfit 11 for connecting a physiological saline bag, the disposable infusion apparatus and the branch pipeline 21 are both provided with a clamp 22, and one side of the clamp 22, which is far away from the liquid medicine bag, on the branch pipeline 21 is provided with a breathable waterproof hole 23 which can be opened and closed; the connecting line 15 is provided with a scale 16 at a portion between the drip chamber 12 and the screw port 14.

The utility model discloses an among the transfusion system of survey central venous pressure, each part of disposable transfusion system, bottle plug puncture ware, drip kettle, flow regulator, screw connector and connecting line, except that the pipeline need connect the branch pipeline, all the other parts all are the same with the ordinary disposable gravity type transfusion system of market.

The utility model discloses a survey transfusion system of central venous pressure when using, liquid medicine bag and normal saline bag are connected respectively to two bottle stopper puncture wares, and spiral interface connects and keeps somewhere the pipeline that the needle equals the human body to connect.

The utility model discloses a survey transfusion system of central venous pressure divide into the infusion and survey central venous pressure two kinds of states. Most of the time is in the state of infusion, and the rest of the time is in the state of measuring central venous pressure. When the infusion set is in an infusion state, if the infusion set needs to be switched to a state of measuring central venous pressure, the clamp on the disposable infusion set needs to be closed firstly, the clamp on the branch pipeline is opened, the physiological saline passage is formed, after the physiological saline washes the liquid medicine in the shared pipeline, the clamp on the branch pipeline is closed, the physiological saline of the pipeline below the clamp does not go downwards any more, after the breathable waterproof hole needs to be opened, the physiological saline of the pipeline below the clamp can continue to go downwards, the liquid level is continuously reduced, and the reading can be carried out after the physiological saline tends to be stable. In the measuring process, the scales need to be kept vertical, and conversion is needed if the scales cannot be vertically inclined. After the measurement is finished, the ventilating waterproof hole is closed, the clamp on the disposable infusion apparatus is opened, and the liquid medicine can flush the physiological saline in the shared pipeline until normal infusion is finished after flushing. When the secondary measurement is needed, the clamp on the disposable infusion apparatus is closed, the clamp on the branch pipeline is opened, some physiological saline is supplemented, then the clamp on the branch pipeline is closed, the physiological saline of the pipeline below the clamp after the breathable waterproof hole is needed to be opened continues to go downwards, the liquid level is continuously reduced, and the reading can be carried out again after the physiological saline tends to be stable.

The utility model discloses a survey transfusion system of central venous pressure can easily realize the infusion and survey the switching of central venous pressure, need not frequently pull out and insert the liquid medicine bag, has avoided the contact with external fungus environment, easy operation, quick convenience.

The connection of the branch line 21 and the disposable infusion set is located above the drip cup 12.

In order to realize the switching between infusion and central venous pressure measurement and reduce the shared pipeline of liquid medicine and physiological saline, the joint of the branch pipeline and the disposable infusion apparatus should be as lower as possible, but the speed of dropping liquid must be controlled and the speed of dropping liquid can not be observed, and a drip cup and a flow rate controller cannot be arranged, so that the joint of the branch pipeline and the disposable infusion apparatus is only positioned above the drip cup.

As a specific embodiment, as shown in fig. 2, the air-permeable waterproof hole 23 includes a through hole 231, an air-permeable waterproof film 232 covering the through hole 231, and a plug 233 provided in association therewith.

When the clamps of the disposable infusion apparatus and the branch pipeline are closed, the part below the clamp of the branch pipeline is not communicated with the outside atmospheric pressure, so that the liquid level does not drop any more, the breathable waterproof hole can be communicated with the atmosphere after being opened, and meanwhile, the physiological saline is prevented from overflowing from the hole. The breathable waterproof film is made of common commercial materials on the market. When not needed, the plug can be plugged to cut off the communication with the external atmospheric pressure.

Optionally, as shown in fig. 3, the length of the plug 233 is slightly smaller than the depth of the through hole 231, the end of the plug 233 located outside the through hole 231 is connected with a handheld rod 234, and the cross-sectional diameter of the handheld rod 234 is smaller than that of the plug 233; the sleeve 24 is sleeved at a position corresponding to the through hole 231 outside the branch pipeline 21, the sleeve 24 can rotate around the branch pipeline 21, the sleeve 24 is provided with a long groove 241 arranged along the rotation direction, the width of the long groove 241 is larger than the section diameter of the handheld rod 234 and smaller than the section diameter of the plug 233, and one end of the long groove 241 is formed into a notch 242 with the size larger than the section diameter of the plug 233.

In order to keep the plug to be convenient to plug and pull out and prevent the plug from falling off accidentally, the sleeve is further arranged, when the sleeve rotates to the position where the notch corresponds to the plug, the plug can be operated through the handheld rod, and when the plug is located in the through hole, the sleeve rotates to the position where the notch is not right opposite to the plug, so that the plug can be prevented from falling off accidentally. The long groove can be rotated conveniently and can be fixed in an auxiliary mode.

Optionally, the plug 233 is made of an elastic material, and the plug 24 is in interference connection with the through hole 231. Not only is the plugging and unplugging convenient, but also the air leakage of the gap between the plug and the outer wall of the accommodating space can be further prevented.
