Abstract
The utility model relates to a disposable infusion apparatus capable of measuring the central venous pressure of a patient. The disposable infusion apparatus is characterized by comprising an infusion tube, a Murphy's tube is arranged on the upper portion of the infusion tube, a bottom port used for being connected with a deep vein port is arranged at the bottom of the infusion tube, graduations are arranged in the middle of the infusion tube, and the graduation range is -10-30cm. The disposable infusion apparatus is simple in structure and convenient to use, can be used for infusion, and can also be used for measuring the central venous pressure of the patient.
Description
Technical field
But this utility model relates to a kind of disposable measuring central venous pressure transfusion device in the medical instruments field.
Background technology
The central venous pressure of human body refers to the pressure of human body right atrium and superior and inferior vena cave thoracic cavity section, and its normal value is 5-12cmH2O.Clinically, can judge whether patient's blood volume is not enough according to the height of human body central venous pressure, or whether cardiac function is incomplete, and comes thus speed and the quantity of regulating transfusion, blood transfusion.At present the mensuration of central venous pressure has two kinds of instrument measuring method and ordinary surveying methods.Instrument measuring method causes and can't promote on a large scale clinically because of the special instrumentation and testing module of needs, therefore commonly uses clinically simplified method measuring center venous pressure.Easy central venous pressure measurer is made of the slide calliper rule with pointer usually, needs to cooperate infusion bottle that normal saline is housed etc. to use simultaneously, is inconvenient to use and time-consuming.The measuring device that uses at present in addition generally is the independent measurement central venous pressure, patient is infused need use respectively two kinds of medical apparatus and instruments with measurement of central venous pressure, therefore operates complicatedly, and use cost is high, has also increased the infected chance of patient.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, but a kind of disposable measuring central venous pressure transfusion device is provided, and is simple in structure, easy to use, both can be used for transfusion, also can be used for the measuring center venous pressure.
For solving above technical problem, the technical solution of the utility model is: but disposable measuring central venous pressure transfusion device, its difference is: it comprises tube for transfusion, the top of described tube for transfusion is provided with Murphy tube, the bottom of tube for transfusion is provided be used to the bottom interface that connects dark vein interface, the tube for transfusion middle part is provided with scale, and scale range is-10cm～30cm that the mark color in 5cm in the scale of described tube for transfusion～12cm scope is different from other scale color.
The contrast prior art, beneficial features of the present utility model is: simple in structure, easy to use; Both can be used for transfusion, also can be used for the measuring center venous pressure.
Description of drawings
Fig. 1 is this utility model embodiment overall structure sketch map;
Wherein: 1-tube for transfusion, 2-Murphy tube, 3-bottom interface, 4-scale.
The specific embodiment
By reference to the accompanying drawings this utility model is described in further detail below by the specific embodiment.
Please refer to Fig. 1, but the disposable measuring central venous pressure transfusion device of this utility model, it comprises tube for transfusion 1, the top of described tube for transfusion 1 is provided with Murphy tube 2, the bottom of tube for transfusion 1 is provided be used to the bottom interface 3 that connects dark vein interface, tube for transfusion 1 middle part is provided with scale 4, and scale 4 scopes are-10cm～30cm.
Preferably, the mark color in 5cm～12cm scope is different from other scale color in the scale 4 of described tube for transfusion 1.
Preferably, on the tube for transfusion 1-distance of 10cm graduation mark place and tube for transfusion 1 bottom is 30cm～40cm, the distance of 30cm graduation mark place and Murphy tube 2 is 50cm～70cm.
In this utility model, scale unit is centimetre that least unit is millimeter.During transfusion, the tube for transfusion top connects infusion bottle, and the bottom interface of tube for transfusion connects dark vein interface; When needing the measuring center venous pressure, vertically place tube for transfusion, then 0 graduation mark on the tube for transfusion is aimed at patient's midaxillary line the 4th intercostal, the tube for transfusion top is separated with infusion bottle, treat that liquid level in the tube for transfusion drops to place, a certain plane and stablizes when motionless, read the tube for transfusion scale value at this place, plane; After finishing using, tube for transfusion bottom interface separated getting final product with dark vein interface.Secondary pollution has been avoided in disposable use after the whole tube for transfusion packaging sterilizing, has improved health and safety.
This utility model has been simplified operating procedure, saves the operating time, has reduced cost; Both can measure the human body central venous pressure, can directly to human transfusion, also can suspend transfusion in order to measure at any time the central venous pressure of human body again.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
