Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a visual guide wire. Background Art

[0002] Intubation is a commonly used technique in clinical anesthesia or emergency treatment. The tube is made of relatively soft PVC. To facilitate insertion, a guide wire is needed to plasticize the tube before insertion. The commonly used intubation methods for clinical nasogastric tubes are as follows: blind insertion, which has high requirements on the operator, is difficult, has a low success rate, and also increases the patient's pain; X-ray guided intubation, due to the radiation of X-rays, the patient needs to be moved to the X-ray room; ultrasound guided intubation, which requires the cooperation of ultrasound equipment. Since direct vision is not possible, the operator is required not only to have relevant ultrasound knowledge, but also to have rich experience and skilled operation techniques. In view of the above situation, the invention of the visual guide wire can effectively alleviate the drawbacks of conventional intubation. The visual guide wire is to place a camera and a light source at the top of the guide wire. However, the current minimum diameter of a medical camera is 1mm. After the camera and light source are set at the top of the guide wire, the diameter of the guide wire is much larger than 1mm. According to the reasonable ratio of the inner and outer diameters of the nasogastric tube, the inner diameter of the commonly used tubes is basically less than 1mm, and the diameter of the matching guide wire is 0.8mm. It is difficult to install the existing 1mm diameter camera plus light source on the 0.8mm guide wire. At present, the traditional solution is to use fiberoptic bronchoscopes, but fiberoptic bronchoscopes are expensive and general grassroots hospitals do not have this equipment. At this time, other medical means will be used for treatment, which will not only bring inconvenience to clinical operations and delay rescue time, but also increase the patient's additional trauma and economic burden. How to overcome the above problems has become a major technical bottleneck. Summary of the invention

[0003] The object of the present invention is to provide a visual guide wire to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A visual guide steel wire comprises a pipe and a guide steel wire. The pipe is sleeved on the guide steel wire and also comprises a fixed disk. The fixed disk is sleeved on the guide steel wire. The fixed disk comprises a disk body, a nut, a locking sleeve and a pagoda joint. The disk body is provided with a water inlet hole. One end of the disk body is detachably connected to the locking sleeve, and the other end of the disk body is detachably connected to the pagoda joint. The nut is detachably connected to the locking sleeve, and the pipe is detachably connected to the pagoda joint. The guide steel wire comprises a plug, a wire core shaft, an outer shell, a spring outer shell, a light beam fiber and a pixel fiber. The wire core shaft, the light beam fiber and the pixel fiber are all connected to the plug and are arranged inside the spring outer shell. The outer shell is wrapped around the outside of the spring outer shell.

[0006] Preferably, it also includes a host, which includes a casing, a control panel, a display screen, a battery, a decoder, a charging port, a socket and a plurality of buttons. The display screen is arranged on the front side of the casing, the control panel, the battery and the decoder are all arranged inside the casing, the charging port is arranged on the top of the casing, the plurality of buttons are arranged on the side of the casing, the socket is arranged on the bottom of the casing, and the guide wire is pluggable and connected to the socket.

[0007] Preferably, the casing comprises an upper casing and a lower casing, and the upper casing and the lower casing are detachably connected.

[0008] Preferably, the number of buttons is 3-5.

[0009] Preferably, threads are provided at both ends of the inner part of the disc body, and the locking sleeve and the pagoda joint are connected to the two ends of the disc body through threads.

[0010] Preferably, the locking sleeve is provided with a plurality of open grooves along the circumferential axial direction at one end of the connecting nut, and a sealing ring is provided inside.

[0011] Preferably, a fixing frame and a cable tie are provided on the fixing plate, and the cable tie is wound around the fixing frame.

[0012] Preferably, the cable tie is a Velcro cable tie.

[0013] The present invention adopts the above structure and has the following advantages: the host and the guide wire adopt a pluggable connection mode. After the host and the guide wire are connected, they can be used as a stand-alone device. The host is provided with a display screen, and the connection mode can be set on the display screen to monitor the connection status and display the operation image. The host can also rely on its own network connection device to connect to the APP of a mobile phone or tablet computer to monitor the intubation image and record the intubation video to prevent medical disputes. The guide wire adopts a plug that matches a conventional fiberoptic bronchoscope, and the guide wire can also be directly inserted into the fiberoptic bronchoscope and used in conjunction with the fiberoptic bronchoscope.

[0014] The fixed plate is adjustable on the guide wire and is equipped with a detachable pagoda joint, which can be used with pipes of different diameters and lengths and has a wide range of applications. A water inlet hole is provided on the fixed plate, and water or lubricating fluid can be injected into the gap between the pipe and the guide wire to flush the guide wire head during intubation to prevent organ mucus from blocking the visual effect, or to lubricate the guide wire when pulling it out to avoid damage to the patient's organs.

[0015] The use of a clustered built-in guide wire increases the longitudinal support force of the wire and facilitates intubation. The wire core shaft, beam fiber and pixel fiber are integrated in the spiral spring housing. The mature technology of optical fiber is used to make the beam fiber and pixel fiber smaller in diameter, so that the overall diameter of the guide wire can be controlled to be thinner, which is suitable for the inner diameter of most pipes. Compared with micro lenses, it has lower costs and wider applications. BRIEF DESCRIPTION OF THE DRAWINGS
