Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent intracranial pressure monitoring system. Background Art

[0002] Increased intracranial pressure can cause brain herniation crisis, which can cause death of patients due to respiratory and circulatory failure. Therefore, it is very important to measure intracranial pressure in time for patients with potential risks. In the existing technology, self-tapping screws are used to measure intracranial pressure. On the one hand, this solution damages the patient's meninges and causes new pain. On the other hand, since it is connected to the skull with threads, it cannot form a good seal. When the internal pressure is high, body fluids such as cerebrospinal fluid may overflow and cause pollution.

[0003] The existing technology conducts detection inside the skull through a pressure measuring end, and then connects to an electrocardiograph through a wired circuit. Although the accuracy of data transmission through wires can be guaranteed, it is very inconvenient during long-term (5-7 days) monitoring, and the wires are easily tangled, which restricts many brain movements.

[0004] In view of the above problems, it is necessary to propose improvements to the existing dura mater pressure measurement, improve the fixing method so as to no longer cause harm to the human body, improve the information connectivity method so that the patient can move more freely, thereby helping to improve the safety and comfort of the pressure measurement operation. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose an intelligent intracranial pressure monitoring system, which transmits wirelessly and fixes by negative pressure, and does not need to be connected and fixed to the skull with threads, so as to solve the pain caused by hard fixation to the skull in the prior art and the inconvenience caused by wired connection.

[0006] The present invention is achieved through the following technical solutions:

[0007] The intelligent intracranial pressure monitoring system includes a shell, an adsorption device arranged at the bottom of the shell and a pressure measuring device arranged in the shell, wherein the shell is an inverted bowl structure, the adsorption device includes a negative pressure chamber and a negative pressure pump, the negative pressure chamber is an annular groove arranged at the mouth of the bowl body and extends into the bowl wall, the negative pressure pump is an exhaust pump arranged in the inner cavity of the bowl body and connected to the negative pressure chamber, annular sealing rings are arranged on the notches on the left and right sides of the annular groove, the inner cavity of the shell is provided with a sealing partition which divides the inner cavity of the shell into two independent upper and lower cavities, the pressure measuring device includes a pressure measuring rod, a signal processor and a pressure display, the pressure measuring rod is vertically sealed and fixed on the sealing partition, one end of which is located in the upper cavity and the other end extends out of the lower cavity, a pressure measuring sensor is arranged at the end of the lower cavity, the signal processor is arranged on the sealing partition and is connected to the pressure measuring sensor through a wire, and the pressure display is arranged outside the shell and is connected to the signal sensor through a wire.

[0008] Furthermore, a guide cone is provided at the front end of the pressure sensor.

[0009] Furthermore, a maintenance opening is provided on the top of the housing, and a sealing cover is threadedly connected to the maintenance opening.

[0010] Furthermore, the sealing cover is made of transparent material.

[0011] Furthermore, the lower cavity is provided with a pressure sensor, and the exhaust pump is provided with pipelines for supplying and exhausting air to the lower cavity.

[0012] Furthermore, the signal processor has a Bluetooth transmission function module.

[0013] The beneficial effects of the present invention are:

[0014] The present invention arranges an annular groove at the bottom of the shell, and then fixes the pressure measuring device in the annular groove by means of negative pressure, thereby avoiding the situation in which the prior art uses a threaded hard connection to cause damage to the patient's skull; at the same time, a display is arranged on the shell, so that the pressure result can be directly displayed without the need for transmission, thereby avoiding the inconvenience caused by the wired transmission in the prior art; in addition, the pressure of the lower cavity is always kept within a range that does not affect the intracranial pressure through the suction and exhaust operations on the lower cavity, thereby ensuring the accuracy and reliability of the detected pressure.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0026] In the above description of the present invention, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0028] like Figure 1-6 As shown, an embodiment of the present invention is: an intelligent intracranial pressure monitoring system 1, comprising a shell 2, an adsorption device arranged at the bottom of the shell and a pressure measuring device arranged in the shell, the shell is an inverted bowl body structure, the adsorption device comprises a negative pressure chamber 3 and a negative pressure pump 4, the negative pressure chamber is an annular groove arranged at the mouth of the bowl body and extending into the bowl wall, the negative pressure pump is an exhaust pump arranged in the inner cavity of the bowl body and connected to the negative pressure chamber, annular sealing rings 5 ​​are arranged on the notches on the left and right sides of the annular groove, the inner cavity of the shell is provided with a sealing partition 6 that divides the inner cavity of the shell into two independent cavities, the upper cavity 7 is located above, and the lower cavity 8 is located below, the pressure measuring device comprises a pressure measuring rod 9, a signal processor 10 and a pressure display 11, the pressure measuring rod is vertically sealed and fixed on the sealing partition, one end of the pressure measuring rod is located in the upper cavity, and the other end extends out of the lower cavity, a pressure measuring sensor 16 is arranged at the end of the lower cavity, the signal processor is arranged on the sealing partition and is connected to the pressure measuring sensor through a wire, and the pressure measuring display is arranged outside the shell and is connected to the signal sensor through a wire.

[0029] The pressure measuring rod is a circular tube, and the wire is set in the inner cavity of the pressure measuring rod. It passes through the pressure measuring rod to connect the two ends for data transmission. Of course, in order to achieve sealing, the area outside the wire in the pressure measuring rod can be sealed to prevent cerebrospinal fluid from entering and causing contamination.

[0030] When implementing this embodiment, the hair of the patient's detection area can be shaved first, and then the pressure measuring rod can be inserted into the detection opening, so that the pressure measuring sensor contacts the internal environment of the brain, and the shell is pressed against the scalp. At this time, the exhaust pump is started to exhaust the air in the negative pressure chamber, slowly form a negative pressure, and finally fix the shell on the scalp. After completion, the exhaust pump is stopped and the installation is completed. At this time, the pressure measuring sensor continuously detects the pressure signal and continuously sends the data to the signal processor. The signal processor amplifies, filters, and converts the data, and then sends the result to the display screen for display.

[0031] The above process completes fixation through negative pressure, which will not cause new trauma to the patient, making it easier for the patient to accept. At the same time, the test results are directly displayed on the outer shell and do not need to be transmitted to the outside by wire, thus forming a wireless usage state, allowing patients to use it more freely and have relatively more space for activities.

[0032] When possible, a guide cone 12 is provided at the front end of the pressure sensor, which can be easily introduced into the intracranial cavity through the guidance of the front end, thereby reducing trauma and even requiring no special drilling for operation.

[0033] As an improvement of this embodiment, a maintenance opening is provided on the top of the housing, and a sealing cover 13 is threadedly connected to the maintenance opening, so that the housing can be opened through the sealing cover for maintenance.

[0034] As a further improvement of this embodiment, the sealing cover is made of a transparent material, such as glass or transparent plastic, so that the situation inside can be observed from the outside, thereby performing timely processing.

[0035] As a further improvement of this embodiment, the lower cavity is provided with a pressure sensor 14, and the exhaust pump is provided with a pipeline for supplying and exhausting gas to the lower cavity. When the pressure sensor finds that the pressure of the lower cavity is greater than the required pressure, the gas can be discharged through the exhaust pump to reduce the pressure of the lower cavity. Otherwise, the gas needs to be increased.

[0036] This solution can make the air pressure in the lower cavity be reasonably adjusted, such as reaching normal atmospheric pressure, or being greater than normal atmospheric pressure, or being less than normal atmospheric pressure, that is, adjusting the pressure relationship between intracranial pressure and external air pressure so that the detected value of intracranial pressure is always the true value.

[0037] As a further improvement of this embodiment, the signal processor has a Bluetooth transmission function module, which can transmit signals with an external Bluetooth receiving terminal 15, thereby realizing wireless communication, which is convenient for medical staff to understand and monitor in real time.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
