Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Example 1 visual tracheal cannula 1
As shown in fig. 1 and 3, a visual tracheal cannula comprises a tube body and a sleeve bag, wherein the tube body comprises a flexible patient end 1, a machine end 3 and a tube cavity 2 extending from the patient end 1 to the machine end, the sleeve bag 4 is arranged at the flexible patient end 1, an inflation channel is arranged on the inner wall of the tube body, the inflation channel is connected with an inflation head outside the tube body, a socket of the cannula is a bevel 8 (an inclined opening), the bevel end is provided with a proximal end 82 and a distal end 81, an adjacent but non-communicated accommodating cavity 11 and an flushing channel 13 are arranged along the inner wall of the tube body extending from the bevel proximal end 82 to the head of the tube cavity, the shape of the tube body can be changed in various ways, for example, as shown in fig. 1, the tube cavity 2 is arc-shaped, the arc-shaped cavity is provided with an outer peripheral area 9 and an inner peripheral area 10 which are arranged on the outer peripheral area 9 of the tube cavity; for example, the lumen is also arc-shaped, but the accommodating cavity and the flushing channel are arranged in the peripheral area, and for example, the shape of the lumen can be linear in some cases, for example, when a supporting spring is arranged in the lumen, the shape of the lumen can be freely changed, so that the catheter body provided by the invention is suitable for any shape of cannula. However, the fact that the receiving cavity 11 for receiving the camera 12 extends from the proximal end 82 of the bezel is important because the existing visible cannula is formed with the receiving cavity at the inner wall of the tube extending from the distal end, which inevitably causes the defect of stiffening of the insertion head, and the "outer peripheral region", "inner peripheral region" and "proximal end" and "outer end" described herein are not limited to one arcuate line or one nearest point, but rather a broad definition, such as proximal end, distal end refers to one region, not one nearest or farthest point, as long as the object of the present invention is achieved. The terms "proximal" and "distal" as used herein are intended to have a reference point relative to a user, with "distal" meaning a position, direction or orientation generally away from the user, and with the term "proximal" meaning a position, direction or orientation generally toward the user.
The camera 12 is built in the accommodating cavity 11, in order to ensure the visualization of the camera 12, it is necessary to ensure that the accommodating cavity 11 is open, the opening direction of the accommodating cavity is consistent with that of the bevel opening, as shown in fig. 2, the accommodating cavity extends along the proximal end 82 of the bevel opening, and the end face of the opening of the accommodating cavity is flush with the proximal end of the bevel opening, which is also important, because if the accommodating cavity opening for accommodating the camera is retracted a small distance together with the camera, physiological tissues can touch the uneven part of the bevel opening during the insertion process, and wounds are easily caused to patients.
To achieve visualization, the distance of the camera head retracting inwards relative to the opening of the accommodating cavity or the proximal end of the bevel opening cannot be too large, and research finds that: when the camera 12 is retracted inwards by 1-2mm relative to the opening end of the accommodating cavity, namely the camera is also retracted inwards by 1-2mm relative to the proximal end of the bevel, for example, 1mm, in the process of performing intubation, firstly, the soft advantage of the bevel is not destroyed by the hard camera, the defect of hardening of the guide head caused by implantation of the camera is avoided, and the clinical effect is good; secondly, the visual effect is optimal. In addition, the size of the accommodating cavity is matched with that of the camera, and various mounting means are adopted, including glue is adhered to the side wall of the accommodating cavity, and other modes such as clamping or screw fixing can be adopted. Meanwhile, the camera can be wrapped by transparent materials, so that the camera is prevented from being directly contacted with human secretion; thus, the flexible characteristic of the flexible patient end is maintained, the defect of stiffening of the intubated patient end caused by the existing visual camera device is eliminated, and the optimal visual effect can be achieved.
As shown in fig. 2, the open end surface of the accommodating cavity 11 is flush with the proximal outline of the bevel, and does not bulge or retract; in addition, the junction of the opening end 110 of the accommodating cavity and the edge of the proximal end of the bevel 8 is in smooth transition, so that the socket of the visual cannula forms an inclined opening 8 with an elliptical edge, the advantage of the soft bevel is not changed, the flexible patient end is reserved, the insertion process is light and labor-saving, the operation of doctors is convenient, and the pain of patients is relieved.
As shown in fig. 1, the accommodating cavity further comprises a wire harness 17 connected with the camera, the wire harness 17 partially penetrates through the lumen 2, and a USB connector 18 connected with the tail of the wire harness is used for realizing an image transmission function; the camera is provided with a light source for illuminating a glottis or facilitating photographing, in one embodiment of the invention, the inner diameter of the accommodating cavity is smaller than 0.5mm, the camera is a CMOS camera with a fixed focal length, and the light source adopts an LED lamp. The patient end side wall is provided with a Murphy's hole 19 and the machine end 3 of the cannula is provided with a joint 31.
Example 2 visual tracheal cannula 2
This embodiment provides a clear function of the camera at any time on the basis of embodiment 1, as shown in fig. 3, showing a sectional view of the patient end, for flushing the camera at the end, preferably the flushing channel 13 is arranged adjacent to the receiving cavity 11, and "adjacent" means adjacent to but not communicating with the inner wall of the tube body as a whole, i.e. they are arranged at intervals, in the embodiment provided by the invention, the receiving cavity is laterally spaced from the inner wall of the flushing channel in the peripheral area of the tube body by a distance of 1-2mm, the flushing channel 13 is provided with a flushing hole 14 bent towards the camera 12 and communicating with the receiving cavity 11 at a position close to the proximal end of the bevel, and the flushing hole 14 is arranged at the end of the flushing channel 13 and is substantially flush with the camera 12, which means substantially flush for achieving the flushing effect. As shown in fig. 1, when the flushing channel 13 extends to the middle upper part of the tube body, the outside of the tube body is connected with the flushing channel and provided with a flushing tube 15 and a flushing connector 16, wherein the flushing connector is used for connecting flushing equipment such as a syringe and the like; therefore, the corrosion of the flushing liquid to the wire harness connected with the camera can be avoided, the stroke of the flushing liquid can be reduced, the impulse of the flushing liquid is ensured, and the cleaning force is high.
In addition, the inventor of the present invention optimally designs the flushing hole, and through repeated screening experiments, it is found that, as shown in fig. 3, the accommodating cavity 11 and the flushing channel 13 extend along the inner wall of the pipe cavity, and the flushing channel 13 bends 30-90 ° towards the camera at a position close to the proximal end of the bevel opening; at this time, two kinds of flushing holes are formed, the flushing holes being perpendicular and inclined with respect to the camera. In an optimized embodiment of the present invention, as shown in fig. 3, the lateral separation distance between the accommodating cavity 11 and the flushing channel 13 is 1.5-1.6mm, and the flushing channel 13 is bent at 50-75 degrees near the bevel opening to point to the camera 12, so as to form an inclined flushing hole 14 for flushing the camera. At this time, the inclination of the flushing holes has the following obvious advantages compared with flushing holes having other inclinations or being vertical: 1. the flushing force is maximum, and impurities of the camera are completely flushed by using liquid or gas with small flow, so that no residue exists; 2. the cleaning agent can directly face the direction of the camera and directly wash away sundries of the camera without any offset, and 3, no additional washing structure is added, and the inner wall of the tube body is skillfully designed, so that the structure is light, and the pain of a patient in the treatment process is greatly relieved.
In addition, the inflation device provided by the invention can comprise an inflation channel, an inflation catheter 5, an indication air bag 6, a single-phase valve 7 and the like, and belongs to the prior art.
