Description

The present invention relates to a small sphygmomanometer with a low battery replacement frequency.

Conventionally, AA type batteries, AAA type batteries, NiCd batteries (rechargeable), etc. have been used for battery-driven blood pressure monitors (automatic blood pressure monitors). In particular, in the case of a sphygmomanometer using AA batteries, AAA batteries, etc., there is a problem that the use frequency limit is limited to about 200 times and it takes time to replace the battery (Patent Document 1: Japanese Patent Laid-Open No. Hei 9-1990). No. 38054, Patent Document 2: JP-A-11-56798). On the other hand, recently, an oxyride battery has been developed for a digital camera as a power source battery having a predetermined current and a long battery life. However, the application of oxyride batteries to sphygmomanometers has not yet been found.

The present invention has been made in view of such circumstances, and an object thereof is to provide a sphygmomanometer (automatic sphygmomanometer) with less battery replacement frequency.

In order to achieve the above object, the sphygmomanometer according to the present invention is an arm insertion type sphygmomanometer that measures blood pressure by automatically pressurizing a cuff by driving a pressurizing pump using a battery as a power source, and the battery is an oxyride battery. It is characterized by being. The wrist sphygmomanometer is characterized in that most of the surface of the main body curved in the circumferential direction of the wrist is used as a display unit for blood pressure values, pulse values, etc., using an oxyride battery as a power source. Features. In the sphygmomanometer in which the cuff band and the main body are integrated, the oxyride batteries in the main body are distributed to both ends of the main body, and both batteries are positioned at the same height when viewed from the cuff band. It is characterized by that. In addition, a portable continuous blood pressure monitor that measures blood pressure by automatically pressurizing a cuff by using a battery as a power source to automatically pressurize a cuff, wherein the battery is an oxyride battery.

According to the sphygmomanometer of the present invention, the battery replacement frequency is halved in normal use as compared with the conventional automatic sphygmomanometer. On the other hand, if the replacement frequency is the same, especially in the case of a wrist blood pressure monitor, the battery can be changed from, for example, AA type to AA type, and the size and weight can be further reduced.

<Comparison test>
In the arm insertion type sphygmomanometer shown in FIG. 1 (a), the number of times of normal use using AA alkaline batteries and the number of times of normal use using AA oxyride batteries Compared. When using AA alkaline batteries (4 batteries: 270 g per battery), it can be confirmed that it can be used 300 times, and when using AA oxyride batteries (4 batteries: 92 g per battery), 300 times can also be confirmed. It was confirmed that it can be used. From this result, it is possible to use AA oxyride batteries instead of AA alkaline batteries if the number of times of use is the same. In that case, the weight of the power battery becomes 1/3, and the sphygmomanometer is reduced in weight. Miniaturization can be achieved. Specifically, the weight is about 1100 gw including the battery, and the weight can be reduced to almost half. Thus, the size and weight can be reduced by changing the AA alkaline battery to the AA oxyride battery and the AA alkaline battery to the AAA oxyride battery. Normally, the wrist blood pressure monitor shown in Fig. 1 (b) uses AA batteries. However, if the number of times of use is the same, AA oxyride batteries can be applied, and the size and weight can be reduced. When an AA oxyride battery is used, the battery replacement frequency is about ½.

Here, an example of the oxyride battery will be briefly described. In an alkaline battery made of a metal positive electrode can, a positive electrode mixture housed in the positive electrode can, and a gelled zinc negative electrode material disposed opposite to the positive electrode mixture via a separator, a carbon-based substance powder is formed on the inner surface of the positive electrode can. A conductive material layer containing a cobalt-based substance powder as a main component is formed. The cobalt-based material contained in the conductive material layer is at least one selected from the group consisting of metallic cobalt, cobalt oxyhydroxide, dicobalt trioxide, cobalt monoxide, and cobalt hydroxide. Moreover, the compounding ratio of the carbon-based material and the cobalt-based material is 1 to 10 parts by mass of the cobalt-based material with respect to 100 parts by mass of the carbon-based material. Further, the positive electrode active material is a nickel hydroxide-based material, and particularly contains nickel oxyhydroxide. Moreover, a positive electrode mixture contains manganese dioxide and nickel oxyhydroxide, The compounding ratio is 20-90 wt% of manganese dioxide, and 80-10 wt% of nickel oxyhydroxide. The positive electrode mixture contains 3 to 8 parts by weight of graphite with respect to 100 parts by weight of the active material. The oxyride battery described above is an example, and the present invention is not limited to this.

  The comparative test showed an example of an arm insertion type sphygmomanometer, but a wrist type sphygmomanometer using AA alkaline batteries (using two) as shown in FIG. 1 (b), as shown in FIG. 1 (c). Portable AA sphygmomanometer using AA alkaline batteries (use 4), portable continuous measurement for 24 hours using AA alkaline batteries (use 4) (measured intermittently every 15 minutes, for example) It has been confirmed that it can also be applied to measuring devices, and can also be applied to other types of blood pressure monitors, such as blood pressure meters that automatically measure and display blood pressure after manually pressing a cuff with a rubber ball, etc. However, the present invention is not limited to this embodiment.

It is an external appearance perspective view of the Example of this invention. It is a block diagram of the Example of this invention.
