Description

Integrated intracranial pressure sensor bougie

Technical Field

The utility model relates to an intracranial pressure sensor bougie, more specifically, the utility model relates to an intracranial pressure sensor bougie of medical integral type.

Background

The intracranial pressure monitoring provides a basis for accurately judging the change condition of intracranial pressure (ICP) caused by space occupying lesions such as intracranial tumors, intracranial wounds, intracerebral hemorrhage and the like in clinic, and can meet the requirements of diagnosis, treatment and prognosis judgment. Intracranial pressure monitoring is therefore of great clinical importance. The catheter of rear end is lived to the current intracranial pressure sensor bougie response head end in the market for metal protective sheath parcel and bonds through glue and become integrative, and the inside encapsulation pressure response chip of metal sheath, catheter and metal protective sheath exist a step in the bonding position, and the step of sensor head end may block at the bone edge when the postoperative sensor takes out, can't take out. In addition, the catheter and the metal protective sleeve are bonded through glue, so that the situation of poor bonding can occur, the metal protective sleeve and the catheter are separated in the using process, and the metal protective sleeve is in the risk of falling in the brain tissue.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art's is not enough, and aim at provides an intracranial pressure sensor bougie of integral type to expect can solve the bougie and block at the bone reason when the postoperative takes out, can't take out or the problem that metal protective sheath drops in the use.

In order to solve the technical problem, the utility model adopts the following technical scheme:

The utility model provides a pair of technical scheme is:

A special fixture for intracranial pressure sensor production, comprising: a conduit (1), a pressure sensing mechanism (2),

The catheter (1) is tubular, a closed opening at the front end (8) is in a cone shape, a hole (3) is formed in the surface of a catheter body at the front end (8), the pressure sensing mechanism (2) is arranged in an inner cavity of the catheter and is tightly fixed, the pressure sensing mechanism (2) is connected with a lead (4), and the lead penetrates out of an opening at the rear end of the catheter through the inner cavity of the catheter; the pressure sensing mechanism (2) is composed of a base (5) and a chip (6), the chip (6) is fixed on the base (5), and a protective layer (7) is arranged on the pressure sensing surface of the chip; the chip (6) is connected with the lead (4), and the chip (6) is communicated with the outside through the hole (3) on the surface of the catheter tube body to monitor the pressure.

The material of the conduit (1) is a high polymer material, which is: TPU, PE, silica gel, PA or modified PA.

The protective layer (7) is a soft rubber layer, and comprises the following components: and (3) a silica gel material.

The chip (6) converts the pressure value on the pressure sensing surface into the change of resistance, current, voltage or capacitance, and transmits the change to external equipment through a lead.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Examples

As shown in fig. 1, the integrated intracranial pressure sensor probe comprises: the catheter comprises a catheter (1) and a pressure sensing mechanism (2), wherein the catheter (1) is tubular, the front end (8) is closed and is in a cone shape, a hole (3) is formed in the surface of a catheter body at the front end (8), and the pressure sensing mechanism (2) is arranged in an inner cavity of the catheter and is tightly fixed. As shown in figure 1, the pressure sensing mechanism (2) is positioned right below a pipe body hole (3) of the catheter, the pressure sensing mechanism (2) is connected with a lead (4), and the lead (4) penetrates out of an opening at the rear end of the catheter through an inner cavity of the catheter. The pressure sensing mechanism (2) is composed of a base (5) and a chip (6). As shown in fig. 2, the chip (6) is fixed over the base (5), wherein the protective layer (7) on the surface of the chip (6) is a soft adhesive layer made of a silicone material. The chip (6) is connected with the lead (4). The base (5) may be of unitary construction or, as shown in figures 5 and 6, the base (5) may be provided with a recess to ensure that the chip (6) is emptied, without the accuracy of the pressure measurement being affected by changes in the stress of the base (5) or by the heat generated by the chip itself. The chip (6) is communicated with the outside through the hole (3), and the chip (6) can convert the pressure value on the pressure sensing surface into the change of resistance, current, voltage or capacitance and transmit the change to external equipment through a lead. The chip (6) is provided with a protective adhesive layer at the joint of the chip and the lead (4) and the base (5), so that the phenomenon that the pressure value cannot be effectively transmitted due to the fact that the lead (4) is connected with the chip through a connecting line to fall off is prevented. As shown in fig. 4, the catheter (1) is a tube with a closed tip and an awl shape, and is made of a high polymer material: TPU, PE, silica gel, PA or modified PA. Catheter (1) formula structure as an organic whole just can not have the phenomenon that the metal protective sheath drops in the use to and when the postoperative doctor took out the sensor, can not block and the phenomenon that can't take out, very big reduction patient's risk.

Although the invention has been described herein with reference to the illustrated embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More specifically, various variations and modifications may be made to the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure herein. In addition to variations and modifications in the component parts and/or arrangements, other uses will also be apparent to those skilled in the art.
