Problems solved by technology

[0007] However, in the process of making this kind of latex bag, on the one hand, the temperature needs to be kept for 1 or 2 hours during molding, the production time is long, and the temperature in the working environment is high; on the other hand, toxic gas will be emitted into the air, causing environmental pollution
At the same time, the molded latex bags and latex tubes will still emit an unpleasant smell
At the same time, the price of latex raw materials has risen sharply in recent years, which has also caused an increase in costs.

Embodiment 1

[0028] Embodiment one: see attached figure 2 And attached image 3 As shown, an inflatable bag for measuring blood pressure includes a rectangular airtight bag body 1, two ventilation tubes 3 fixedly connected and communicated with the bag body, the bag body is made of polyvinyl chloride, and consists of two surfaces and It consists of 4 sides, one of which has an integrated bending structure, and the other three sides are sealed and connected to the two surfaces through a heat-press bonding structure 2; There are two holes 4, and one end of the two vent pipes is respectively sealed and connected to the edge of the holes through a thermocompression bonding structure 2.

[0029] The manufacturing method of this embodiment is,

[0030] (1) Cut the polyvinyl chloride calendered film into pieces of the same size and shape as the unfolded surface of the air bag (for example, cut into 225mm x 240mm pieces), and the thickness of the polyvinyl chloride film is between 0.5mm and 0.8...

Abstract

The present invention discloses an inflatable bag for measuring blood pressure and its making method. It includes a rectangular closed bag body and two air tubes which are fixedly connected with said bag body and communicated each other. It is characterized by that the described bag body is made up by using polyvinyl chloride, and the described air tubes are rubber tubes.

Description

technical field [0001] The invention relates to a component of a measuring device for diagnostic purposes, in particular to an inflatable bag in a device for measuring cardiac and vascular pressure. Background technique [0002] Blood pressure is an important indicator when diagnosing human health conditions. The blood flowing in the blood vessel is the same as the water flowing in the flat and smooth river channel. Usually there is no sound, but when the blood or water flows through the narrow pipe to form a vortex, it can make a sound. The sphygmomanometer for measuring human blood pressure is based on this principle Designed. [0003] At present, the indirect measurement method is commonly used to measure blood pressure clinically. The sphygmomanometer used is composed of three parts: a balloon, a cuff and a manometer. An inflatable bag is arranged in the cuff, and is respectively connected with the balloon and the manometer through two pipelin...
