Embodiment Construction
[0020] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0021] Referring to Fig. 1, the pressure detection device is composed of a pump door 5 with a pump door pressure block 1 and a pressure sensor 8 with a pressure contact 2, wherein the pressure sensor 8 is installed on the mounting plate 6 through the mounting hole 65, and the pump The door 5 and the mounting plate 6 are connected together through a hinge 9 . The infusion tube 10 is interposed between the pump door pressing block 1 and the pressure contact 2 .
[0022] As shown in Figure 1, two L-shaped briquetting block fixing parts 4 opposite to each other are arranged on the surface 51 of the pump door 5, and the T-shaped pump door briquetting block 1 is arranged between the two briquetting block fixing parts 4, and Its transverse protruding part 11 is squeezed against on the two transverse parts 41 of pressure block fixing part 4 by the elastic forc...

The invention discloses a pressure detector used for a perfusion tube, including: a pump gate, the first surface of which is provided with a pump gate lock block; and a pressure transducer arranged on a mounting panel by a mounting hole and provided with a pressure contact which extends out of the second surface of the mounting panel; the first surface is opposite to the second surface, the pump gate is connected with the mounting panel and can rotate relatively to the mounting panel, wherein, the first surface of the pump gate is provided with two fixing parts for the lock block, which are spaced, the pump gate lock block is extruded between the two fixing parts for the lock block by the elasticity of a spring; and two lug bosses which are opposite to each other are symmetrically arranged on the mounting panel around the mounting hole. The pressure detector can ensure the stability of the matching between the pump gate lock block and the contact of the pressure transducer in the long-term use, avoid the error of the measuring of perfusion pressure, and avoid damage to patients.
Description
technical field [0001] The invention relates to a pressure detection device, in particular to a pressure detection device for medical infusion tubes. Background technique [0002] The medical pump is a kind of infusion auxiliary medical equipment, which is suitable for various infusion occasions that require precise control of infusion speed and infusion volume. Influence, based on the consideration of patient safety, the infusion pressure detection device is used to monitor the infusion pressure in various infusion tubes, so that when the pressure in the infusion tube exceeds the allowable pressure range, the sound and light alarm will be triggered in time to prompt the medical staff to deal with it to ensure the safety of patients . [0003] Most of the infusion tube pressure detection devices in the prior art adopt a split structure, which is composed of a pressure sensor and a pump door pressing block, and the two are connected by a hinged device. When in use, the pres...
