Embodiment 1

[0014] Embodiment 1: This embodiment is in figure 1 In the process, the pressure sensing signal (6) of the contact position of the needle contact position of the puncture needle tube (1) is transmitted to the physiological saline in the hose (2) filled with physiological saline, and then the pressure sensing signal (7) transmitted by the physiological saline Pass it to the pressure sensing device (3), after the pressure sensing device (3) converts the pressure into data, it transmits the pressure digital signal (8) to the display alarm device (4), and at the same time, the display alarm device (4) sends it to the pressure sensing device (3 ) is powered by the DC power output (5). combine figure 2 , to further illustrate the structure and principle of the pressure sensing device in this technical solution, in figure 2 In the process, one end of the hose for filling normal saline is put on the pressure guiding tube (201), and the hose nut (202) is tightened by rotating clock...

Embodiment 2

[0016] Example 2: In Figure 5 Among them, the pressure data signal line and the pressure sensing device power supply line (208) use their own power supply battery 1 (501) to provide DC power for themselves and the pressure sensing device, and at the same time receive the pressure data signal. After internal analysis and processing, the power supply green indicator The light (301) is on to indicate that the device has been powered and is in normal operation; the green indicator light (305) of the arriving vein is on, indicating that the current needle contact position is a vein; the red indicator light of the arriving artery (306) is on, indicating that the current needle contact position has been reached artery.

[0017] Below by embodiment 3, in conjunction with attached image 3 , Image 6 , Figure 7 , further specifying the technical solution of the present invention.

Embodiment 3

[0018] Example 3: In Image 6 In the process, the power supply of the pressure sensing part is provided by the power supply battery 2 (610), and one end of the hose for filling physiological saline is put on the pressure guiding tube (201), and the hose nut (202) is tightened by rotating clockwise to fix the hose. Open the valve (203), let the pressured physiological saline enter the sensing area of ​​the pressure sensor (204), pull up the deflation rubber plug (206), the rubber head at the bottom lifts up the gap, and discharge the gas from the exhaust port (207) , pull 3 times to ensure that the exhaust is complete. The pressure sensor (204) senses the pressure change, and after being processed by the sensor transmission unit (205), the signal is sent out through the built-in pressure data wireless transmitting antenna (609). combine Figure 7 , to further illustrate the specific realization of the display alarm device, in Figure 7 Among them, the jack 220VAC input (401)...

Abstract

The invention provides a method and a device for instructing deep venous puncture and catheterization in severe case emergency medical treatment. A hose containing normal saline is arranged behind a puncture needle tube, pressure in the contact position of a needle head is conducted by the normal saline, pressure in the contact position of the needle head is sensed in real time by a pressure sensor and displayed on a displaying and alarming device, the position of the needle head operated by a doctor is promoted according to differences of pressure changes in arteries, veins and non-blood vein positions, in particular, an alarm can be given out in time when the needle head is contacted with the arteries, besides, the doctor has experience, and accordingly, the puncture success rate is stabilized and increased; the device is compact, does not influence other operations and is convenient to use; the device contacted with a patient is non-electrified equipment, the pressure sensing device and the display alarming device are connected through a data line, and the safety of the patient is improved.

Description

technical field [0001] The invention relates to a method and a device for instructing deep vein puncture and catheterization for medical emergency rescue, in particular to a method and a device for guiding catheterization by real-time monitoring of needle contact position pressure. Background technique [0002] In patients with complex and changeable conditions, ordinary peripheral venous channels are difficult to meet the needs of rapid drug administration and infusion. The establishment of a large venous channel can provide a rapid infusion route and monitor central venous pressure. At the same time, it can be used for right heart catheterization , Hemodialysis and other treatments are fully prepared. The deep vein is a large blood vessel near the heart, and the tube in this position is an ideal channel for hemodynamic monitoring, infusion, intravenous hypertrophy, cardiopulmonary resuscitation, and placement of a cardiac pacing catheter. Current methods include physician...
