In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
As shown in fig. 1 and 2, the visual hard laryngoscope sheath of the present disclosure comprises a sheath body 1 and an endotracheal tube fixing mechanism.
The bushing body 1 comprises a front support section 11 and a middle resilient section 12. The front supporting section 11 corresponds to the free end of the tube core of the visual hard laryngoscope, and the transparent part 110 is arranged on the front supporting section 11. The transparent part 110 is abutted against the camera of the visual hard laryngoscope.
The front support section 11 and the middle resilient section 12 may be made of the same material. For example, the front support section 11 and the middle elastic section 12 are both made of transparent rubber. The thickness of the front support section 11 may be slightly greater than the thickness of the middle elastic section 12, so that the front support section 11 has a greater force-bearing deformation capability, and the transparent part 110 of the front support section 11 is prevented from being broken by the tube core. The elastic deformation capability of the middle elastic part 12 enables the length of the sleeve body 1 to be adjusted within a certain range, so that the purpose of changing the length of the sleeve body 1 is achieved.
Alternatively, the front support section 11 and the middle elastic section 12 are made of different materials. For example, the front support section 11 is made of PMMA (polymethyl methacrylate), and the middle elastic section 12 is made of silicone. The shape of the front supporting section 11 made of PMMA is stable, and the front supporting section can be stably supported on a camera of a visual hard laryngoscope, so that the shooting clarity of the camera is ensured, and the camera is prevented from being influenced by the reflection of light of the front supporting section 11. The elastic deformation capability of the middle elastic section 12 enables the length of the sleeve body 1 to be adjusted within a certain range, so that the purpose of changing the length of the sleeve body 1 is achieved.
The tracheal catheter fixing mechanism comprises a tracheal catheter fixing main body 2. The tracheal catheter fixing body 2 is connected with the free end of the middle elastic section 12, and a tube core through hole 21 is arranged on the tracheal catheter fixing body 2. The core of the visual hard laryngoscope can be inserted into the cannula main body 1 from the core through hole 21. In general, the die through-hole 21 may be a shape that facilitates the penetration of a die having a certain curvature.
The tracheal catheter fixing body 2 can be fixed on a tube core of the visual hard laryngoscope in a mode of interference fit, elastic cap clamping and the like.
The endotracheal tube fixing body 2 may be made of a material having a certain hardness, for example, a phenolic plastic or a polyurethane plastic. Generally, the hardness and the elastic modulus of the endotracheal tube fixing body 2 are larger than those of the middle elastic section 12.
The connection between the tracheal catheter fixing body 2 and the middle elastic segment 12 can be realized by plastic welding or injection molding.
The connecting end of the endotracheal tube can be positioned on the endotracheal tube fixing main body 2. In specific implementation, the tracheal catheter can be positioned on the tracheal catheter fixing main body 2 in a sleeving and fixing mode; alternatively, the endotracheal tube may be positioned on the endotracheal tube fixing body 2 by means of an annular pressing member; still alternatively, the endotracheal tube may be positioned on the endotracheal tube fixing body 2 by a clip.
After the sleeve of the visual hard laryngoscope is sleeved on the tube core of the visual hard laryngoscope, the position of the tracheal catheter fixing mechanism on the tube core can be changed through the elastic deformation of the front supporting section 11 and/or the middle elastic section 12, so that the tracheal catheter fixing mechanism can adapt to the fixing requirements of tracheal catheters of different models. Moreover, the visual hard laryngoscope sleeve of this disclosure can be folded and accomodate.
After the endotracheal tube intubate is accomplished, can pull out the hard laryngoscope sleeve pipe of visual hard laryngoscope tube core for the tube core keeps clean state.
In one embodiment of the visual hard laryngoscope sleeve of the present disclosure, in order to improve the elastic deformation capability of the middle elastic section 12 on the basis of ensuring the support performance of the front support section 11 and the stability of the cooperation with the tube core, the elastic modulus of the front support section 11 is 30-1000 times of the elastic modulus of the middle elastic section 12.
Furthermore, the front support section 11 is made of hard plastic, and the middle elastic section 12 is made of silica gel or rubber. The hard plastic may be, for example, a phenolic plastic, a polyurethane plastic, an epoxy plastic, or the like. The transparent part 110 may be a PMMA plate. The transparent part 110 made of PMMA material has good optical performance, and is beneficial to improving the shooting clarity of the camera of the visual hard laryngoscope.
To promote ease of use of the visual hard laryngoscope sheath, the length of the front support section 11 may be 2-10% of the length of the sheath body 1.
In one embodiment of the visual hard laryngoscope sheath of the present disclosure, as shown in fig. 1, the core penetration hole 21 has a support portion 211 and a flared portion 212, the support portion 211 and the flared portion 212 are disposed opposite to each other, and the hardness of the support portion 211 is greater than that of the flared portion 212. The inner diameter of the core through-hole 21 is gradually reduced in a direction toward the middle elastic segment 12.

The support portion 211 may be made of a rigid plastic such as a phenolic plastic or a polyurethane plastic, and the flared portion 212 may be made of a material similar to that of the middle resilient section 12. Thus, when the core having a certain curvature passes through the endotracheal tube fixing body 2, it can smoothly enter the tube main body 1 in cooperation with the flared portion 212 having a certain elastic deformability. Also, the support portion 211 can effectively and reliably provide support to the core when the endotracheal tube fixing body 2 is fixed to the core of the visual hard laryngoscope.

The fixing member 4 may be, for example, a snap ring or a hoop. The endotracheal tube fixing mechanism is reliably fixed to the tube core by means of pressing and applying force to the endotracheal tube fixing body 2.
Further, the fixing member 4 is a bolt threadedly coupled with the endotracheal tube fixing body 2. By rotating the fixing member 4, the end of the fixing member 4 can be pressed against the flared portion 211 located outside the tube core, so that the tube core is pressed against the supporting portion 211, and the fixing of the endotracheal tube fixing body 2 and the tube core is realized.
In one embodiment of the visual hard laryngoscope sleeve of the present disclosure, as shown in fig. 2, the inner wall of the tube core perforation 21 is provided with a circumferential protrusion 22 which is in interference fit with the tube core of the visual hard laryngoscope. The annular bulge 22 can ensure the tight fit of the tube core through hole 21 and the tube core of the visual hard laryngoscope, and prevent the tracheal catheter fixing body 2 from sliding off uncontrollably.
In one embodiment of the disclosed visual hard laryngoscope sleeve, the endotracheal tube fixing body 2 is provided with an annular wall 23, and the annular wall 23 is used for sliding fit with the endotracheal tube. The annular wall 23 is disposed around the main body 1 of the cannula and the connecting end of the endotracheal tube is slidably engaged with the inner or outer wall surface of the annular wall 23. The annular wall 23 is typically made of a rigid material, such as a rigid plastic, which has some supportive nature. The provision of the annular wall 23 facilitates better positioning of the endotracheal tube by the endotracheal tube fixing body 2.
In one embodiment of the visual hard laryngoscope sleeve of the present disclosure, the endotracheal tube fixing mechanism further comprises an inflation tube 3, and the inflation tube 3 is mounted on the endotracheal tube fixing body 2. The inflation pipeline 3 can be communicated with the tracheal catheter, so that the function of inflating the tracheal catheter is realized.
