Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an automatic blood pressure measuring device, and in particular to a cuff connection device suitable for use in an automatic blood pressure measuring device used when regularly visiting and measuring the blood pressure of a plurality of living organisms. It is related to.

One type of use of the conventional automatic blood pressure measuring device is periodic blood pressure measurement. This is carried out in a hospital or the like to observe blood pressure fluctuations of a living body (patient) over a long period of time, and is usually carried out at regular intervals on a plurality of living bodies. Conventionally, even in such periodic blood pressure measurements, like normal automatic blood pressure measuring devices, fluid is pumped through a cuff that is wrapped around a living body to compress a part of the living body, and then a part of the living body is compressed. A device was used in which a blood pressure needle body was integrally connected to the body of the blood pressure needle, which measures the blood pressure of a living body by discharging the pressure fluid in the cuff and releasing the pressure from the cuff.

For this reason, in conventional periodic blood pressure measurements, it is troublesome to wrap or remove the cuff for each living body. In addition, in conventional routine blood pressure measurement, each time the blood pressure measurement of each living body was completed, the measurement results obtained for that living body had to be recorded on a designated recording form, which made the entry process cumbersome. There was also a risk that incorrect blood pressure information would be mixed in due to typographical errors.

Problems to be Solved by the Invention On the other hand, as a means of dealing with the above-mentioned problems, it is possible to separate the automatic blood pressure measuring device into the main body of the blood pressure monitor and assemble the connecting parts provided therein. It is conceivable to provide a cuff connecting device that connects the cuff to the blood pressure needle main body to allow fluid circulation, and to connect the cuff to the blood pressure meter main body with the cuff connecting device when blood pressure is measured.

If the blood pressure measuring device is configured in this way, by leaving separate cuffs wrapped in advance around the living body that is subject to periodic blood pressure measurement, it is possible to easily connect each cuff to the blood pressure needle body using the cuff connecting device. It becomes possible to sequentially measure the blood pressure of each living body by simply connecting and releasing the cuff, and the conventional cumbersome operations of wrapping the cuff around the living body and removing it from the living body are no longer necessary. However, if the cuff connecting device that connects the blood pressure monitor itself simply has the function of connecting them, winding and removing the cuff becomes easy, thus reducing the time required for regular round blood pressure measurements. Although it was possible, it was not possible to omit the entry operation to record the measurement results.

Means for Solving the Problems The cuff connection device according to the present invention has been developed in view of the above circumstances, and its gist is to a cuff, the cuff being optionally connected to the cuff for pumping fluid into the cuff to compress the part of the living body, and then discharging the pressurized fluid in the cuff to release the compression by the cuff; In an automatic blood pressure measuring device equipped with a blood pressure monitor main body that automatically measures the blood pressure of a living body, the cuff and the blood pressure monitor main body each have a connecting part, and the connecting parts are combined with each other. , a cuff connection device for connecting the cuff to the blood pressure monitor main body so as to allow the fluid to flow therethrough, the cuff connection device comprising: (a) storage means provided at each connection portion on the cuff side and storing in advance identification information unique to the cuff; , (b) detection means provided at the connection part on the blood pressure monitor main body side and detecting the identification information stored in the storage means when the connection part is mutually combined with the connection part on the cuff side. It consists in including.

Function and Effect of the Invention By configuring the cuff connecting device in this way, it becomes possible to sequentially measure the blood pressure of multiple living organisms around which the cuff is wound by a simple operation of connecting and separating the cuff connecting device. Therefore, when an automatic blood pressure measuring device using this is used for regular round blood pressure measurements, in addition to shortening the time required for the regular rounds, when the cuff connecting device is connected to the blood pressure needle body, The detection means provided in the connection part on the blood pressure monitor main body side detects the identification information stored in advance in the storage means provided in the connection part on the cuff side, and the connected cuff is detected from the detected identification information. ,
In other words, it is possible to identify the living body around which the cuff is wrapped.
By storing the identification information and the blood pressure measurement result obtained when the cuff is connected as cents, - Eliminate the operation of writing the measurement result on a prescribed recording form every time blood pressure measurement of a living body is completed. I can do it.

Embodiment Hereinafter, one embodiment of the present invention will be described in detail based on the drawing numbers.

First, FIG. 1 shows the state of use of an automatic blood pressure control device equipped with a cuff connection device 10, which is an embodiment of the present invention. In the figure, reference numeral 12 denotes a bag-shaped cuff, which is wrapped in advance around the arms, etc. of a plurality of living organisms (not shown). 14 is a portable blood pressure monitor body, which is equipped with a BOSE 1G for supplying fluid such as air to the cuff 12, and also includes a fluid supply/drainage device, a blood pressure measurement circuit, a measurement data storage device, a power source, etc. Built-in. The distal end of the hose 16 and the cuff 12 are connected via a cuff connecting device IO, as shown.

As shown in FIG. 2, the cuff connection device 10 consists of a cuff side connection part 18 on the cuff 12 side and a main body side connection part 2o on the blood pressure monitor main body 14 side, which are detachable from each other. As shown in FIGS. 3 and 4, it has the shape of a longitudinal flat plate with mating surfaces 22 and 24 facing each other.

The cuff-side connecting portion 18 is made up of a back member 26 housed in the space of the cuff 12 and a front member 28 placed outside the cuff 12, and protrudes outward from the connecting portion attachment hole 30 of the cuff 12. The boss portion $2 of the back member 26 is fitted into a recess 34 formed on the back surface of the front member 28 and fixed by adhesive, thereby being airtightly attached to the cuff 12.

Further, an L-shaped hose connection part 36 is integrally formed on the back surface (the surface opposite to the combination surface 24) of the main body side connection part 20, and the hose 1 is attached to the tip of the hose connection part 36.

When the combination surfaces 22 and 24 are brought into close contact with each other, the cuff-side connecting portion 18 is concentrically connected to the connecting portion attachment hole 30 of the cuff 12 so as to connect the space inside the cuff 12 to the hose 16. A hole 46 is formed, and a through hole 48 is formed in the main body side connection portion 20 through the hose connection portion 36. Through these vent holes 46, 48 and the hose 16, fluid such as air is forced into the cafe 2 from the blood pressure monitor body 14, and fluid forced into the cuff 12 is discharged. In the case of the blood pressure monitor body 14, the blood pressure of the living body is automatically determined based on the change in the magnitude of the pulse wave obtained during the blood pressure increase process or the blood pressure decrease process, for example, the change in the magnitude of pressure vibration within the cuff 12. The determined blood pressure is displayed on the display unit 50 (FIG. 1) and is also stored in a memory of a storage device such as a RAM bank. Note that the fluid is pumped into the cuff 12 and the fluid is discharged from there by a fluid supply/drainage device consisting of a pump, a discharge valve, etc. provided in the blood pressure monitor main body 14, and pulse wave detection and Blood pressure is determined by a blood pressure measurement circuit including a pressure sensor and a microcomputer provided in the blood pressure monitor body 14, which are well known and essential for understanding the present invention. Since this is not a specific matter, a detailed explanation thereof will be omitted. Moreover, in FIG. 1, 49 is a start push button for starting blood pressure measurement, and 51 is a stop push button used when stopping blood pressure measurement midway.

As shown in FIG. 3, on the combination surface 22 of the cuff side connection part 18, two annular protrusions 52 are formed concentrically at the opening of the through hole 46, and the main body side connection Part 20
As shown in FIG. 4, on the combination surface 24, two annular grooves 54 are formed concentrically at the opening of the through hole 48, corresponding to the annular protrusion 52. Further, an annular sole member 56 is attached between the two annular a54 of the main body side connecting portion 20, and as shown in FIG. 1
8 and 20, the annular projection 52 is fitted into the annular groove 54, and the seal member 56 is pressed against the annular portion 58 between the annular projections 52. By fitting these annular protrusions 52 into the annular groove b4 and pressing the sole member 56 against the annular portion 58, airtightness is maintained between the combination surfaces 22 and 24, and the through hole 4
6 (48), fluid is efficiently pumped from the blood pressure monitor main body 14, and the discharge of fluid from the cuff 12 can be well controlled. be.

Further, as shown in FIG. 2, the cuff side connecting portion 18 has a memory storage space 62 formed in such a state that the opening of the combination surface 224 is closed with a lid member 60.
An EFROM (rewritable ROM) 66 as a storage means is housed in the memory housing space 62 and is always urged toward the lid member 60 by an elastic member 64 . This EP ROM 66 is housed in the memory housing space 62 with the terminals 68 facing the lid member 60, and the terminals 68 are placed in the portion of the lid member 60 corresponding to each terminal 68 of this EFROM 66 on the combination surface. A through hole 70 is formed to expose the portion 22.

In the EPROM 66 accommodated in the memory accommodation space 62 in this way, unique identification information file (TD code) for identifying the cuff 12 is stored in advance.

On the other hand, as shown in FIG. 2, on the main body side connection part 20, connection terminals 72 as detection means are provided in a state of being protruded from the combination surface 24 corresponding to each terminal of the EPROM 66. is provided. These connection terminals 72
For example, the leads are integrally molded with the connection part 20 with the other end exposed at the distal end surface of the hose connection part 36, and the leads are inserted into the bows 16 at the exposed parts on the hose connection part 36 side. It is connected to the blood pressure monitor main body 14 via a line 74. In a state where both the connecting portions 18 and 20 are connected, each connecting terminal 72 is inserted into the through hole 70 of the lid member 60 and brought into contact with each terminal 68 of the EPROM 66.

That is, when measuring the blood pressure of a living body, as shown in FIG. , the EPROM 66 is connected to the blood pressure monitor main body 14 via a connection terminal 72 and a lead wire 74, and identification information unique to the cuff 12 stored in advance in the EPROM 66 is detected by the connection terminal 72. The data is read into the blood pressure monitor main body 14 via a lead wire 74. And this EPR
The identification information read from the OM 66 is stored in a storage device such as the RAM block along with the blood pressure value determined for the living body.

Note that when the connecting terminal 72 and the terminal 68 of the EPROM 66 are in contact with each other, the EPROM 66 is configured to be able to press the elastic member 64 and retreat.
is not pressed against the terminal 68 of the EPROM 66- with more force than necessary, and therefore the connection terminal 72 and the
OM66 will not be damaged.

As is clear from the above description, according to the blood pressure measurement device equipped with the cuff connection device 10 according to the present embodiment, when measuring blood pressure, the main body side connection portion is attached to the connection portion 18 of the cuff 12 that has been wound around the living body in advance. 20, the blood pressure of the living body can be measured, and when blood pressure measurement is completed, simply disconnecting the connection allows the blood pressure measurement of the next living body to be performed. In other words, if such an automatic blood pressure measuring device is used for periodic blood pressure measurements, individual cuffs 12 can be wrapped around multiple living organisms to be measured in advance, allowing for extremely simple operation. It is possible to change the living body to be measured,
Compared to the case of using a conventional blood pressure measuring device which requires cumbersome operations such as winding and removing the cuff 12 for each living body, the time required for periodic round blood pressure measurements can be significantly shortened.

Furthermore, as described above, the cuff 12 is wrapped around the living body.
The main body side connection part 2 of the blood pressure monitor main body 14 is connected to the cuff side connection part 18 of the blood pressure monitor main body 14.
By simply connecting 0, the unique identification information of the cuff 12 is stored in the storage device along with the blood pressure value determined for that living body, so the results can be updated each time the blood pressure measurement of an individual living body is completed, unlike conventional methods. This eliminates the need to enter information into a designated recording form. This also reduces the time required for regular patrols. Note that the latest blood pressure data stored in the storage device in the blood pressure monitor main body 14 is transferred and stored in the blood pressure analysis and recording device in which long-term blood pressure information for each living body has already been recorded after the regular round blood pressure measurement is completed. However,
At this time, since the blood pressure data of each living body is stored in the storage device in the blood pressure monitor main body 14 together with the identification information unique to the cuff 12 as described above, if the memory is RAM punctured, tape, etc., the blood pressure data By simply transferring the data to the blood pressure analysis and recording device, or if the memory is a RAM or the like fixedly provided in the blood pressure monitor body 14, the contents can be transferred to the blood pressure analysis and recording device using a cable or the like. This makes it possible to automatically perform data processing on blood pressure data for each living body, such as determining blood pressure trends and the presence or absence of abnormalities. The patient's name and ID code number are used as identification information, but if a unique number attached to the cuff 12 is used, the unique number must be matched in advance to the living body around which the cuff 12 is wrapped. Just leave it there. Therefore, compared to the case where the blood pressure values recorded using a circulating light are input into a microcomputer or the like and data processing is performed, there is an advantage that the mixing of incorrect information due to input errors is completely eliminated.

Although one embodiment of the present invention has been described above, this is literally an illustration, and the present invention should not be interpreted as being limited to this specific example.

For example, in the above embodiment, the cuff side connecting portion 18 has the host portion 32 of the back member 26 fitted into the recess 34 of the front member 28,
Although the cuff side connection part 18 was attached airtightly to the cuff 12 by being fixed with adhesive, it is only necessary to attach it airtightly to the cuff 12, so there is no need to remove it.
Various structures may also be adopted.

Further, in the embodiment described above, the hose connection part 36 is integrally formed with the main body side connection part 20, but the hose connection part 36 may be formed separately. In this case, the connecting portion of the connecting terminal 72 with the lead wire 74 is connected to the through hole 4 of the main body side connecting portion 20.
What is necessary is just to provide it so that it is exposed at 8. Of course, this is not the only case; the connecting portion of the connecting terminal 72 and the lead wire 74 may be exposed outside of the through hole 48 or the internal space of the hose 16, and the lead wire 74 may also be connected to the hose 16. It may be placed outside.

Further, in the embodiment, the annular protrusion 52 formed on the cuff side connecting portion 18 and the annular groove 5 formed on the main body side connecting portion 2o
4 and the sealing member 56 attached between the two annular grooves 54, the airtightness of the through hole 46 (4, 8) was maintained. Various structures can be adopted for the sealing mechanism.

Further, in the above embodiment, the EPROM 66 has an elasticity fJ+A
By being elastically supported by '64, the connecting terminal 72 comes into elastic contact with the terminal 68 of the EPROM 66, thereby preventing the connecting terminal 72 and the EPROM 66 from being damaged. By firmly attaching each connecting terminal 72 to the connecting portion 18 and elastically attaching each connecting terminal 72 to the main body side connecting portion 2o via an elastic member such as a spring, the connecting terminal 72 and B P'
The terminals of the ROM 66 may be brought into elastic contact.

Furthermore, the same effect can be expected even if the contact terminal 72 itself is made to have elastic force.

Further, in the above embodiment, the EPROM 66 is used as a storage means.
was adopted, but the storage means were non-volatile RAM with fixed contents and resistor ROM.

Barcodes, other electrical markings such as holes or protrusions displaying symbols,
Optical or mechanical storage means may be used.

However, just as a barcode reader is used as a barcode detection means, a photocoupler 3 corresponding to the storage means is used.
It is necessary to employ a detection means such as a micro switch.

Further, in the embodiment described above, the connection between the cuff side connecting portion 18 and the main body side connecting portion 20 is performed by engaging the engaging claws 38 and 40 formed thereon with the engaging grooves 42 and 44. However, instead of these, both the connecting parts 18 and 20 are connected by providing a clip mechanism on one of the connecting parts and a clipped part on the other, and having the clipped part gripped by the clip mechanism. You can do it like this.

Furthermore, in the embodiment, the hose 16 is connected to the blood pressure monitor main body 14.
The distal end of the hose 16 is connected to the cuff 12 via the cuff connection device 10, but the cuff connection device 10 may be provided in the middle of the hose 16, or the cuff 2 A boce 16 may be provided on the side, and the end thereof opposite to the cuff 12 may be connected to the blood pressure monitor main body 14 via the cuff connection device 10. In addition, when a part or all of the hose 16 is installed in the cuff 2 measurement, a hose fixing means such as a fastener or a rubber snap device is attached to the cuff 12 so that the hose 16 does not interfere with the movement of the living body during measurement. Alternatively, it is preferable to provide the hose 16 at the distal end of the hose 16 so that its end can be detachably fixed to the cuff 12 while the hose 16 is wound around the cuff 12.

Although others are not listed, it goes without saying that the present invention can be implemented in various modifications and improvements without departing from the spirit thereof.
