Technical Field
The utility model relates to the technical field of medical instruments, in particular to a central venous pressure measuring ruler.
Background
The Central Venous Pressure (CVP) is the pressure in the right atrium and the thoracic segments of the superior and inferior vena cava, and can be clinically used for judging the comprehensive conditions of blood volume, cardiac function and blood vessel tension of patients. The central venous pressure measurement unit is generally in centimeters of water (cmH)2O), the currently used assay methods in clinical use are: connecting the infusion apparatus with a physiological saline bottle, exhausting gas in the infusion tube, closing the infusion apparatus, and filling the infusion tube with the solutionThe pressure measuring device is connected with a conduit inserted into a patient, the infusion tube is tightly attached to the pressure measuring ruler and is kept vertical, the zero scale line of the pressure measuring ruler is ensured to be in the same horizontal line with a pressure measuring standard point in the patient, the infusion device is separated from the physiological saline bottle, the infusion tube is communicated with the atmosphere, the flow regulator on the infusion tube is opened by lifting the infusion device with one hand, at the moment, liquid in the infusion tube flows into the patient, and the scale value of the pressure measuring ruler corresponding to the liquid level of the water column when the liquid level of the water column in the infusion tube is lowered to be stable is the pressure value.
The method for measuring the central venous pressure commonly used in clinic needs to be matched with a measuring ruler. Chinese patent No. CN 205697781U discloses a multifunctional medical ruler, in which a measuring ruler is provided with a groove for placing an infusion tube, and the change of the liquid level in the infusion tube can be read through the scale close to the groove. Chinese patent No. CN 211094060U discloses a pressure measuring scale in body cavity, which is provided with an aligning rod to ensure that the measuring scale is in a vertical state when measuring the venous pressure.
However, the existing central venous pressure measuring ruler does not have the function of automatically reading and displaying the measuring result, so that the data of the graduated scale needs to be read by naked eyes in the measuring process, and the problem of inaccurate reading exists.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model provides a central venous pressure measuring scale which comprises a first measuring scale and a second measuring scale, wherein one end of the first measuring scale is buckled with one end of the second measuring scale through a rotary lock catch.
As an improvement, the system also comprises a signal processor electrically connected with the miniature photoelectric sensor.
As a further improvement, the device also comprises a display screen electrically connected with the signal processor.
As a further improvement, the rotary lock enables the first and second measuring scales to be fixed in position relative to each other under a condition of being perpendicular to each other.
As a further improvement, a hose groove is arranged along the first measuring scale.
As a further improvement, the miniature photoelectric sensor is a groove-type photoelectric sensor.
As a further improvement, the device also comprises a battery box and a switch.
The central venous pressure measuring scale provided by the utility model can sensitively reflect the central venous pressure change of a patient, has the function of automatically displaying the measuring result, is simple and quick in operation process, and avoids errors possibly caused by reading by naked eyes.

Detailed Description
The present invention will be explained more specifically with reference to the drawings and embodiments.
Some embodiments relate to a central venous pressure measuring ruler, which can automatically display the measuring result, and the structure of the ruler is shown in fig. 1, and comprises a first measuring ruler (1) and a second measuring ruler (2), wherein one end of the first measuring ruler is buckled with one end of the second measuring ruler through a rotating lock (3), and a plurality of micro photoelectric sensors (preferably OPTEK OPB350W25Z) (4) are uniformly arranged on the surface of the first measuring ruler along a straight line, and the width of a middle groove of the micro photoelectric sensors is 4.8-6.3 mm. A lead is embedded in the first measuring scale (photoelectric sensors, leads and other components are integrated on a circuit board, and the circuit board is arranged in the first measuring scale), a plurality of micro photoelectric sensors are connected in parallel, the circuit is as shown in figure 2, and outputs signals to a signal processor at the other end of the first measuring scale, and the signal processor converts the photoelectric signals into central venous pressure (cmH)2O) data and transmitted to a display screen, preferably a LED digital display screen, which may be provided at the end of the first measuring scale remote from the rotary latch.
The edges of the first measuring scale (1) and the second measuring scale (2) are provided with scales which take centimeters as units and start from zero, and when the two scales are opened to form a right angle, the zero scale lines of the two scales are superposed.
During the use, open two rulers of central venous pressure dipperstick, place first dipperstick perpendicularly, the second dipperstick level is placed, places the coincidence point of the zero scale mark of two rulers at patient's axillary midline fourth rib, and transfer line (hose) are perpendicular with the body surface, hug closely first dipperstick and place in between photoelectric sensor's light projector and photic device. When the number on the display screen is stable, the central venous pressure of the patient is read. The scales on the first and second measuring scales may assist the operator in accurately marking the location of the pressure measurement standard point on the patient's body (the fourth rib of the axillary midline).
In some embodiments, the signal processor is embedded within the first measuring scale and the display screen is placed within a display screen window on the second measuring scale.
In some embodiments, the rotary lock catch is provided with a slot, so that the first and second measuring scales can be fixed in position relative to each other under the condition of being perpendicular to each other, and the two scales are kept in a perpendicular state.
In some embodiments, the first measuring scale is provided with a hose groove.
When in use, the transfusion tube (hose) is placed in the hose groove.
In some embodiments, the micro-photoelectric sensor is a groove-type photoelectric sensor, the light projector is arranged on one side of the inner side of the groove, the light receiver is arranged on the opposite side of the inner side of the groove, and the infusion tube (hose) can be placed in the groove of the photoelectric sensor during use.
In some embodiments, the central venous pressure measurement ruler is provided with a battery box and a switch.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
