Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a detection pressure take-out port of a pressure sensor for measuring a cuff pressure provided on a substrate on which electronic components are mounted, and a cuff provided in a container. The present invention relates to an improved sphygmomanometer in which a flexible cuff pressure extracting tube that connects a pressure and an air circuit having the same pressure is prevented from being kinked (the tube is collapsed and the passage is blocked).

[Prior Art] Conventionally, the inside of the cuff of a sphygmomanometer with a built-in electric pump has a predetermined low pressure that is not directly involved in blood pressure measurement, and when the cuff pressure is, for example, 20 mmHg or less, the cuff pressure is increased or decreased. In order to efficiently perform the operation in a short time, the air is directly moved into and out of the cuff from the electric pump or the open valve. Therefore, as shown in FIGS. 5 and 6, the detection pressure take-out port 3a of the pressure sensor 3 for measuring the cuff pressure attached to the substrate 2 provided in the container 1 and the cuff provided in the container 1 are shown. The pressure and an air circuit (not shown) having the same pressure are connected by a flexible cuff pressure take-out tube 4 which passes through the lower side of the substrate 2.

[Problems to be Solved by the Invention] However, the space through which the pressure take-out tube 4 is passed must be an extremely thin space due to the restriction due to the miniaturization of the container. Therefore, the tube often bends at the time of assembly, causing a kink 4a, which often causes pressure. It may not be possible to measure. Therefore, it is necessary to take great care in assembling the tube so as not to cause a kink, but it has not been possible to achieve perfection. Also, kinks can occur over time.

In order to solve this problem, the present invention provides a dedicated connector between the detection pressure extraction port of the pressure sensor for measuring the cuff pressure and the flexible cuff pressure extraction tube which is passed through the lower side of the substrate, and the kink of the tube is provided. It is intended to provide a blood pressure monitor that can be prevented.

[Means for Solving the Problems] A sphygmomanometer of the present invention includes a pressure sensor having a detection pressure extraction port in a part, an air circuit airtightly connected to a cuff,
A sphygmomanometer having a connecting means for airtightly connecting the detection pressure take-out port and the air circuit in a container, wherein the connecting means has one end extending in one direction and the one direction. A connector having rigidity is provided, which has another end formed to extend in a substantially orthogonal direction and a ventilation hole formed to extend from the one end to the other end, and one end of the connector has the detection pressure extraction port. It is characterized in that it is hermetically connected to the port.

[Operation] The connector is rigid and has one end formed to extend in one direction, the other end formed to extend in a direction substantially orthogonal to the one direction, and from the one end to the other end. And a ventilation hole formed by extension. Therefore, in the sphygmomanometer of the present invention, the air circuit that is airtightly connected to the cuff can be connected to the connecting means provided with the connector that is airtightly connected to the detection pressure output port of the pressure sensor, and the cuff pressure output can be obtained. Prevents kink of the tube.

The connector may have any shape except for both ends as long as it can be attached to a sphygmomanometer.

[Example] (Example 1) As shown in FIG. 1, a blood pressure monitor of Example 1 according to the present invention is
A short tubular detection pressure extraction port 3a of a pressure sensor 3 for measuring the cuff pressure, which is passed through a hole 2a formed in the substrate 2, and a flexible cuff pressure extraction tube 4 which is an air circuit airtightly connected to the cuff. L-shaped hole 5a as a connecting means for air-tightly connecting and

Connector 5 has fitting protrusions 1b, 1 provided on the lower portion 1a of the container.
Supported by b.

Therefore, after connecting the connector 5 and the short tube 6 to each other, the connector 5 and the cuff pressure extracting tube 4 are connected to each other, and the fitting projections 1b and 1b are used to position the connector 5 in the lower portion 1a of the container, and one port 5b. Position it facing upwards.
Then, the detection pressure take-out port 3a of the pressure sensor 3 mounted on the substrate 2 so as to cover the substrate 2 may be inserted into the short tube 6 almost linearly and connected to prevent kink of the tube and facilitate connection. The assemblability can be improved.

As the material of the connector 5, hard plastic, aluminum, stainless steel, brass or the like is used.

(Embodiment 2) As shown in FIG. 2, a blood pressure monitor according to Embodiment 2 of the present invention is
When the detection pressure take-out port 3a is inserted and connected to the short tube 6 which is fitted and connected to the port 5b, the short tube 6
Since the plug-in connection becomes impossible when the pipe is tilted, the short tube 6 has a gap to be fitted and connected to the port 5b, extends beyond the port 5b, and has a slight gap to the short tube 6. The point that the connector 5 having rigidity is provided with the short tube tube fall prevention wall 5d that is provided so as to surround the short tube tube 6 and that regulates the short tube tube 6 so that the short tube tube 6 does not become unconnectable. This is different from the first embodiment.
