Embodiment 1

[0032] An interventional pressure probe verification device, such as figure 1 Shown, includes airtight body and airtight lid.

[0033] The sealed tank, such as figure 2 As shown, it is a cylinder made of metal material. The upper opening is formed at one time, and a sealing ring groove and external thread are provided; a heating plate is installed in the middle, and the wire of the heating plate is externally connected for temperature control. As shown in the figure, the inner wall of the tank (avoiding the opening position) encapsulates the electric heater, and the electric heater protrudes from the through hole of the sealing cover when it is powered on, so as to ensure uniform temperature in a certain area in the cavity.

[0034] The sealed can lid, such as image 3 As shown, there is an internal thread, which is engaged by the thread and sealed with a rubber ring to seal the opening of the tank. It has a vent with an inner diameter of 3-10mm, connected to the air circu...

Embodiment 2

[0041]An interventional pressure probe verification device includes a sealed tank body and a sealed tank cover.

[0042] The sealed tank body is a cylinder made of metal material. The upper opening is formed at one time, and a sealing ring groove and an external thread are provided; it does not need a built-in heating plate device, and the sealed tank is placed in a temperature control range of 1-2 In heating devices such as constant temperature baths and high and low temperature test chambers, the vacuum structure can keep the internal temperature of the chamber relatively stable.

[0043] The sealing tank cover has an internal thread, which is engaged with the thread and uses a rubber ring to seal the opening of the tank body. It has a vent, connected to the air circuit and a digital pressure controller, to precisely control the pressure in the sealed tank. It has a platinum resistance inlet, and the platinum resistance is used as a temperature sensor for precise temperatur...

Abstract

The invention discloses an involvement type pressure probe calibration device which comprises a tan cover and a tank body which are matched to form a closed space. The tank cover comprises at least one assembling hole, and the bottom of the assembling hole is provided with an elastic material ring with a hole for sealing and provided with a sealing plug matched with the elastic material ring with the hole; the sealing plug is used for assembling an involvement type pressure probe so as to enable the rubber ring with the hole to deform to form mechanical extrusion seal with the involvement type probe. The device probe is easy to disassemble, the sealing effect is good, the adopted parts can form the standard size, and mechanical production is facilitated. Multi-probe sealing can be achieved, and the working efficiency is improved; in the sealing process, no impurity is introduced, and pollution to the involvement type pressure probe is avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment, and more specifically relates to an interventional pressure probe verification device. Background technique [0002] The use of interventional medical pressure probes can make the most realistic measurement of various physiological pressures such as arterial pressure, central venous pressure, pulmonary artery pressure, left coronary artery pressure and intracranial pressure, and provide guidance for the diagnosis and treatment of patients' conditions. [0003] At present, most of the commercially available interventional medical pressure probes use optical fiber sensors and microelectronic sensors, and the outside is covered with polymer catheters. In order to reduce the damage to the patient's body, these probes are characterized by small outer diameters and long tube lengths, and many of them have thicker ends and thinner tubes. Before leaving the factory, these probes must be verified and cal...
