Embodiment 1

[0014] like Figure 1 to Figure 2 The liquid injection tube for the invasive pressure monitoring sensor shown includes the liquid injection tube body 1 provided with the tapered tube 1-1-1, the tapered tube 1-1, and the tapered tube 1-1 are respectively connected by three connecting bands 2 to have three The arc braces positioned and locked at the bottom of the tube body 4 have the same shape as the three arc braces, namely arc braces 3, arc braces 5 and arc braces 6; The matching arc-shaped block 3-1 and the bottom lining plate 3-3 connected with the arc-shaped block 3-1, each bottom lining plate 3-3 in this embodiment is provided with a radial protrusion 3-4 ; The outer wall of the arc-shaped block 3-1 is provided with a buckle 3-2 and a toothed buckle belt 3-5; The toothed buckle belt 6-1 on the outer wall of the block is buckled together, and the toothed buckle belt 3-5 on the outer wall of the arc block 3-1 is interlocked with the buckle 5-1 on the outer wall of another ...

Embodiment 2

[0016] like image 3 and Figure 4 The shown needle tube matched with the injection tube of the invasive pressure monitoring sensor includes a tube body 4 with a nipple 4-1, and the nipple 4-1 of the tube body 4 is matched with the tapered tube 1-1 of the injection tube body 1, The bottom of the pipe body 4 is provided with three radial grooves, and the widths of the radial grooves correspond to the widths of the three radial protrusions on the three arc-shaped backing plates 3-3 respectively.

[0017] During use, after the nipple 4-1 on the pipe body 4 is inserted into the tapered pipe 1-1, three arc-shaped braces are mounted on the bottom of the pipe body 4, so that the radial direction on the bottom lining plate of the three arc-shaped braces The protrusions are respectively embedded in the three radial grooves at the bottom of the tube body 4, and then the toothed buckles on the adjacent arc-shaped blocks are sequentially connected with the buckles to fix the needle tube ...

Abstract

The invention provides an invasive pressure monitoring sensor liquid injection tube and a needle tube matching the same and belongs to the technical field of medical instrument manufacture. The invasive pressure monitoring sensor liquid injection tube comprises a liquid injection tube body with a taper tube; the taper tube is connected with a plurality of arc-shaped supports for locating and locking of the bottom of a tube body; each arc-shaped support comprises an arc-shaped block matching the side wall of the tube body and a bottom liner plate connected with the arc-shaped block, wherein the bottom liner plate is at least provided with one radial protrusion; each arc-shaped block is provided with a clamping buckle and a toothed fastening belt on the outer wall. The problem in the prior art that the conventional invasive pressure monitoring sensor liquid injection tube often causes falling-off of a needle tube is solved.

Description

technical field [0001] The invention relates to the technical field of medical device manufacturing, in particular to a liquid injection tube used for an invasive pressure monitoring sensor and a needle tube matched with it. Background technique [0002] The role of the invasive pressure monitoring sensor is to monitor the invasive blood pressure of the human body, such as arterial pressure, central venous pressure, pulmonary artery pressure, and left coronary artery pressure, and directly obtain the physiological parameter of blood pressure, which can be used for clinical diagnosis and treatment of diseases. Provide an objective basis for predicting the prognosis. An injection tube with a switch is provided on the invasive pressure monitoring sensor, and at the end of the injection tube, there is a conical tube matched with the needle nipple of the syringe; when in use, the needle cone must be inserted through the needle nipple On the conical tube, various medicaments can ...
