Description

Blood pressure measuring device Technical Field The present invention relates to a blood pressure measuring device to be attached to a wrist. Background In recent years, blood pressure measurement devices for measuring blood pressure are used not only in medical facilities but also in households as a means for confirming health conditions. The blood pressure measuring device, for example, expands and contracts a cuff wrapped around an upper arm, a wrist, or the like of a living body, and detects the pressure of the cuff by a pressure sensor, thereby detecting vibration of an arterial wall to measure blood pressure. As such a blood pressure measuring device, a so-called integrated blood pressure measuring device is known in which a cuff and a device body for supplying a fluid to the cuff are integrally formed. Further, the integrated blood pressure measuring device may be a wearable device attached to the wrist. As a technique for attaching a blood pressure measurement device to a wrist, a technique for fastening and fixing a band provided in a device body to the wrist in a state in which a cuff is disposed inside the band is known. In addition, as such a blood pressure measuring device, a technique is known in which a collar is used between the cuff and the band in order to bring the inflated cuff into close contact with the wrist. In such a blood pressure measuring device, the cuff is fixed to the inner peripheral surface of the collar. In addition, japanese patent application laid-open No. 2019-118418 discloses a technique in which a collar and a cuff are fixed to a device body via a rear cover, and the cuff is connected to a flow path portion continuous with a pump fluid. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2019-118418 Disclosure of Invention Problems to be solved by the invention In the above-described blood pressure measuring device that is attached to the wrist using the band, the cuff and the band are separate, and therefore, when the user attaches the blood pressure measuring device to the wrist, the cuff and the band may be attached to the wrist so as to be offset relative to each other in the axial direction of the wrist along the longitudinal direction of the forearm. If the band and the cuff are offset in the axial direction of the wrist, the cuff is not pressed against the wrist properly when measuring the blood pressure, and the accuracy of blood pressure measurement may be lowered. Accordingly, an object of the present invention is to provide a blood pressure measuring device capable of preventing a decrease in blood pressure measurement accuracy. Technical proposal According to one aspect, there is provided a blood pressure measuring device to be attached to a wrist of a user, comprising a case having a case body, an attached portion provided at one of circumferentially symmetrical positions on an outer peripheral surface of the case body, a shaft portion provided at the other, the attached portion provided at a wrist side of the case body, a pump accommodated in the case body and in fluid communication with the attached portion, a cuff having a connection portion provided at a portion opposed to the wrist side of the case body and connected to the attached portion, the cuff being in fluid communication with the pump via the connection portion, and a band having a bag body accommodating the cuff therein and having a band shape wound around the wrist, the attachment portion having a hole provided at one end side in a longitudinal direction, one end portion of the attachment portion being fixed to the bag body and being in fluid communication with the attached portion, and a folded-back portion provided at a position from the one end side of the bag body to the other end portion being in a position shorter than the attachment portion, and a fixed portion being in fluid communication with the pump. The cuff is inflated by being supplied with a fluid, and includes a bag-like structure such as an air bag. According to this aspect, the cuff is disposed in the bag body. Therefore, when the blood pressure measuring device is attached to the wrist, even if the cuff moves in the axial direction of the wrist in the bag body, the cuff is accommodated in the bag body, and therefore the cuff can be appropriately pressed against the wrist. As a result, the blood pressure measurement accuracy can be improved. In the blood pressure measuring device according to the above aspect, there is provided the blood pressure measuring device, wherein the connected portion and the connecting portion are configured to be inserted from one side to the other side. According to this aspect, the connecting portion can be simply connected to the connected portion. In the blood pressure measuring device according to the above aspect, there is provided the blood pressure measuring device, wherein the mounting portion has flexibility. According to this aspect, the m
