Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims. In the following examples, the end closer to the patient is defined as the proximal end, and the end further from the patient is defined as the distal end

Example 1

As shown in fig. 1, the operation protection device for a bedside fiberoptic bronchoscope disclosed in this embodiment includes a bendable and telescopic protection hose 1, and in this embodiment, the protection hose 1 includes a fold section 1-1, a first straight section 1-2 located at a proximal end of the fold section 1-1, and a second straight section 1-3 located at a distal end of the fold section 1-1. The structure of the fold section 1-1 refers to the structure of the elbow part of the suction pipe which can be bent and extended commonly used at present, and the integral bending and extension of the protective hose 1 are realized through the fold section 1-1. In order to ensure the bending and stretching effect of the protection hose 1 as a whole, the length of the corrugated section 1-1 can be designed to be L, assuming that the protection hose 1 has an overall length

Or is

The specific length is determined according to specific requirements.

The straight pipe section I1-2 is connected with the joint component I2, and the straight pipe section II 1-3 is connected with the joint component II 3. In the embodiment, the connection mode between the straight pipe section I1-2 and the joint component I2 is the same as the connection mode between the straight pipe section II 1-3 and the joint component II 3. The following description is made of the connection between the straight pipe sections one 1-2 and the fitting assembly one 2:

the inner wall of the end part of the straight pipe section I1-2 is provided with a circle of semicircular bulge I1-1-1, and the outer wall of the end part is provided with a circle of semicircular bulge II 1-1-2. It should be noted that after reading the present application, the number of the semicircular projections one 1-1-1 and the semicircular projections two 1-1-2 can be arbitrarily set by those skilled in the art according to the requirement.

The first connector component 2 comprises a hollow first body, and the middle part of the first body is provided with a hollow bayonet 2-1. The bronchoscope penetrates through the first body and then is clamped into the bayonet 2-1, and is tightly matched with the first body and the bayonet 2-1. A circle of clamping grooves I2-2 are wound around the bayonet 2-1. A circle of semicircular groove I2-3 and a circle of semicircular groove II 2-4 are respectively arranged on the groove walls at the two sides of the clamping groove I2-2. The number of the semicircular grooves I2-3 and the semicircular grooves II 2-4 corresponding to the semicircular protrusions I1-1-1 and the semicircular protrusions II 1-1-2 can also be determined according to requirements. The semicircular grooves I2-3 correspond to the semicircular bulges I1-1-1 one by one, and the semicircular grooves II 2-4 correspond to the semicircular bulges II 1-1-2 one by one.

Since the protection hose 1 is made of soft plastic, the joint assembly one 2 is generally made of hard plastic. Therefore, the end part of the straight pipe section I1-2 can be clamped into the clamping groove I2-2 through the deformation of the material, the semicircular bulge I1-1-1 can be clamped into the semicircular groove I2-3, and the semicircular bulge II 1-1-2 can be clamped into the semicircular groove II 2-4. The connection firmness between the straight pipe section I1-2 and the connector assembly I2 can be improved and a certain sealing effect can be achieved by arranging the semicircular bulge I1-1-1, the semicircular bulge II 1-1-2, the semicircular groove I2-3 and the semicircular groove II 2-4.

The straight pipe sections II 1-3 and the joint assembly II 3 are connected and fixed through the structure, and the details are not repeated. Except that the construction of the second connector assembly 3 differs from the first connector assembly 2 described above.

The second joint component 3 is used for forming detachable connection with a silica gel cover of the extension pipe, and in combination with fig. 3, the second joint component 3 includes a second hollow main body, and the distal end of the second main body is the groove for connecting with the second straight pipe section 1-3, which is not described herein again. The proximal end of the second connector component 3 is provided with a plurality of clamping sheets 9 arranged along the circumferential direction, and a certain gap is formed between every two adjacent clamping sheets 9. In order to ensure the connection effect, the height of the clamping sheet 9 is not too high (i.e. the length along the axial direction of the second connector assembly 3), in this embodiment, the height of the clamping sheet 9 is 5mm, and meanwhile, the gap between two adjacent clamping sheets 9 is not too large, in this embodiment, the gap is 1.5 mm. The end of each tab 9 is formed with a hook formation 10. Since the second connector component 3 is usually made of rigid plastic and thus has a certain elasticity, when the silicone cover is snapped into the opening formed by all the snap tabs 9, all the snap tabs 9 will simultaneously expand outward and generate a restoring force due to the material, so that all the snap tabs 9 will be fastened on the outer circumferential surface of the silicone cover along the circumferential direction under the restoring force. Meanwhile, all the hook structures 10 are clamped on the outer circumferential surface of the silica gel cover due to the reasonable height setting of the clamping sheets 9. Because the utility model discloses can abandon after once using, consequently the condition of joint piece 9 can not exist and relapse the joint, ensures that joint piece 9 can not be because of repeated deformation fracture.

Referring to fig. 4, it can be seen from fig. 4 that the distal end of the second connector component 3 has a groove structure similar to that of the first connector component 2, and the detailed description thereof is omitted. The second body of the second joint component 3 is internally provided with a first guide plate 3-1, a bowl-shaped sealing element 8 and a second guide plate 3-1 from the far end to the near end in sequence. The bowl-shaped sealing member 8 is made of medical grade silicone and thus has a certain elasticity. The bottom of the bowl-shaped sealing member 8 is cut to form a scoring structure 8-1, and the scoring structure 8-1 may be Y-shaped, herringbone-shaped, cross-shaped, or other shapes. The first guide plate 3-1 is provided with a first guide hole which is opposite to the scratch structure 8-1. The bronchoscope insertion tube penetrates through the first guide hole and then is guided to the scratch structure 8-1 of the bowl-shaped sealing part 8, and the bronchoscope insertion tube pushes the scratch structure 8-1 open and then continuously penetrates into a second guide hole in the second guide plate 3-2. Otherwise, when the diagnosis and treatment are finished, the bronchoscope insertion tube is pulled out of the artificial airway, and after the bronchoscope insertion tube is pulled out of the bowl-shaped sealing piece 8, the scratch structure 8-1 can be automatically closed by the elasticity of the material to form sealing again due to the fact that the bowl-shaped sealing piece 8 has certain elasticity, so that the bronchoscope insertion tube pulled out of the artificial airway and the body of a patient can be relatively sealed in the protective hose 1.

When the silica gel cover is clamped into the opening formed by all the clamping sheets 9, the second guide plate 3-2 is attached to the silica gel cover, and the guide holes in the second guide plate 3-2 are aligned with the through holes in the silica gel cover. In order to increase the attaching effect, an adhesive layer can be additionally arranged on the second guide plate 3-2, the second guide plate 3-2 is adhered to the silica gel cover through the adhesive layer, and the firm connection degree of the second joint component 3 and the silica gel cover can be increased while the attaching effect is increased. At the moment, the bronchoscope insertion tube which is out of the bowl-shaped sealing part 8 can enter the artificial airway through the guide hole II on the guide plate II 3-2 and the through hole on the silica gel cover, and then enters the body of a patient to diagnose.

Example 2

With reference to fig. 5, the present embodiment differs from embodiment 1 in that: in this embodiment, the protection hose 1 is a plastic film hose 4 that can be bent and stretched at will, and the plastic film hose 4 is made of polyurethane (TPU), so that the protection hose can be freely contracted and extended while being completely closed.

To match the plastic foil hose 4, the first connector part 2 and the second connector part 3 do not have a corresponding groove structure, but instead are replaced by a connection structure shown in fig. 5, which includes a metal ring 5, and the lower half of the metal ring 5 is fixed to the outer circumferential surface of the first connector part 2 or the second connector part 3. The fixing manner of the metal ring 5 on the first joint element 2 or the second joint element 3 may be various, for example, a ring groove may be formed on the first joint element 2 or the second joint element 3, and the lower half portion of the metal ring 5 is embedded therein, and after reading the present application, the skilled person may also adopt other conventional manners to fix the metal ring 5 to the first joint element 2 or the second joint element 3. The upper half of the metal ring 5 is folded outward in a natural state. The end part of the outward turning part of the metal ring 5 is provided with N circles of tooth-shaped bulges 6, and N is more than or equal to 3. Meanwhile, N circles of tooth-shaped grooves 7 matched with the tooth-shaped protrusions 6 are formed in the outer circumferential surface of the first joint component 2 or the second joint component 3. After the end part of the plastic film hose 4 is sleeved outside the first connector component 2 or the second connector component 3, the upper half part of the metal ring 5 is turned inwards until the tooth-shaped protrusions 6 are clamped into the tooth-shaped grooves 7, so that the end part of the plastic film hose 4 can be firmly clamped between the metal ring 5 and the outer circumferential surface of the first connector component 2 or the second connector component 3.

The other structures and operation principles of this embodiment are the same as those of embodiment 1, and are not described herein again.
