Description

Technical Field

[0001] The utility model belongs to the technical field of airway tubes, in particular to a disposable laryngeal mask airway tube. Background Art

[0002] The disposable laryngeal mask airway tube is a ventilation device mainly used in general anesthesia, sedation and first aid. It is inserted into the patient's throat to establish an artificial airway to ensure that the patient can breathe smoothly during surgery or treatment. Compared with traditional endotracheal intubation, the laryngeal mask airway tube is easier to operate and causes less irritation to the throat and trachea, thereby reducing the risk of complications.

[0003] During the operation, the tracheal tube needs to be placed in the laryngeal mask and placed together with the tracheal tube into the human airway, and then the cuff is inflated through the inflation tube to fix the position of the cuff. However, the inflation tube of the existing laryngeal mask airway tube is separated from the tracheal tube. Because the inflation tube is relatively thin and the inflation port is provided with a one-way valve and an indicator airbag, the inflation tube will shake and even separate from the cuff, thereby affecting the progress of the operation.

It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] refer to Figures 1 to 3 , a disposable laryngeal mask airway tube, comprising a mask bag 1, the mask bag 1 is connected to a tracheal tube 2, the mask bag 1 is also connected to an inflation tube 3, the inflation port of the inflation tube 3 is provided with an indicator balloon and a one-way valve, the end of the tracheal tube 2 away from the mask bag 1 is connected to a connecting pipe 4, the connecting pipe 4 is detachably connected to a clamping member 5, and the clamping member 5 is provided with a clamping assembly 6 for fixing the inflation tube 3;

[0026] The connecting tube 4 includes a connecting portion 41 and a raised portion 42. The raised portion 42 is sleeved on the surface of the connecting portion 41 and divides the connecting portion 41 into two sections. One end of the connecting portion 41 is plugged into the end of the tracheal tube 2 away from the cuff 1.

[0027] The tube clamp 5 includes an upper clamp 51 and a lower clamp 52 . The upper clamp 51 is sleeved on a section of the connecting portion 41 away from the tracheal tube 2 , and the lower clamp 52 is located on a section of the connecting portion 41 close to the tracheal tube 2 and is plugged into the upper clamp 51 .

[0028] The present invention is provided with an upper clamping piece 51 and a lower clamping piece 52. The upper clamping piece 51 is sleeved on a section of the connecting portion 41 away from the tracheal tube 2, and the lower clamping piece 52 is located at a section of the connecting portion 41 close to the tracheal tube 2. When the lower clamping piece 52 is inserted into the upper clamping piece 51, the upper clamping piece 51 and the lower clamping piece 52 clamp the protrusion 42, so that the entire tube clamp 5 is connected to the connecting tube 4. Through this arrangement, the tube clamp 5 can be reused and can also cooperate with the clamping assembly 6 to fix the position of the inflation tube 3.

[0029] It should be noted that the tube clamp 5 may be disinfected after each use.

[0030] Furthermore, an inserting block 9 is connected to the surface of the lower clamping member 52 , and a slot 10 is provided on the surface of the upper clamping member 51 , into which the inserting block 9 is inserted.

[0031] Furthermore, a pressure plate 11 is slidably connected to the inner wall of the slot 10, and a second elastic member 12 is connected to the surface of the pressure plate 11 on the side away from the plug 9. The other end of the elastic member 12 is fixedly connected to the inner wall of the slot 10. The surface of the pressure plate 11 on the side close to the lower clamp 52 is inclined, and the plug 9 is located in the slot 10 and has a hook protruding on the surface of the side away from the pressure plate 11. A hook groove is provided on the inner wall of the slot 10, and the pressure plate 11 squeezes the plug 9 so that the hook is inserted into the hook groove.

[0032] In actual use, when the insert block 9 is inserted into the slot 10, it first contacts the inclined surface of the pressure plate 11, thereby driving the pressure plate 11 to move. When the insert block 9 is fully inserted into the slot 10, due to the force of the elastic member 12, the pressure plate 11 will press the insert block 9 and insert the hook portion of the insert block 9 into the hook groove.

[0033] It should be noted that, due to the cooperation between the hook portion and the groove and the arrangement of the pressing plate 11 and the second elastic member 12 , the inserting block 9 can be prevented from falling out of the slot 10 .

[0034] refer to Figure 4 and Figure 5The clamping assembly 6 is provided with two groups and is connected to the lower clamping member 52. The two groups of clamping assemblies 6 include a clamping block 61 and an elastic member 62. The clamping blocks 61 are slidably connected to the clamping tube member 5. The two ends of the elastic member 62 are respectively connected to the clamping block 61 and the clamping tube member 5. The two groups of clamping blocks 61 are symmetrically arranged. The corresponding surfaces of the two groups of clamping blocks 61 are provided with clamping grooves. The two groups of clamping grooves form a closed ring. The side of the two groups of clamping blocks 61 away from the tracheal tube 2 is inclined. The inflation tube 3 contacts the inclined surface of the clamping block 61 to push the two groups of clamping blocks 61 away from each other. The inflation tube 3 moves between the two groups of clamping grooves and is fixed by the inner wall of the clamping groove.

[0035] Furthermore, a groove 8 is provided on the surface of the lower clamp 52, and mounting grooves 63 are provided on both sides corresponding to the groove 8. The two groups of clamping blocks 61 are respectively slidably connected in the two groups of mounting grooves 63, and the two ends of the elastic member 62 are respectively connected to the inner wall of the mounting groove 63 and the surface of the clamping block 61.

[0036] In actual use, after the cuff 1 is inflated, the inflation tube 3 is directly pushed toward the clamping block 61. First, the inflation tube 3 will contact the inclined surface of the clamping block 61, so that the two groups of clamping blocks 61 move away from each other until the inflation tube 3 moves into the clamping groove. The two groups of clamping blocks 61 clamp the inflation tube 3 under the action of the elastic member 62 to fix the inflation tube 3 and prevent it from shaking.

[0037] Furthermore, the elastic member 1 62 and the elastic member 2 12 are both compression springs.

[0038] refer to Figure 5 and Figure 6 Two sets of unlocking components 7 are provided on the lower clamping member 52, and the two sets of unlocking components 7 are respectively connected to the two sets of clamping blocks 61. The two sets of unlocking components 7 include triggering members 71. Pressing the triggering member 71 makes the two sets of clamping blocks 61 move away from each other, thereby taking out the inflation tube 3 in the clamping groove.

[0039] Furthermore, the unlocking assembly 7 also includes a connecting rod 72 and a tension spring 73. The corresponding two side surfaces of the lower clamping member 52 are provided with a sliding groove 74. The two groups of connecting rods 72 are slidably connected to the inner walls of the two groups of sliding grooves 74 respectively. One end of the connecting rod 72 is connected to the trigger member 71, and the trigger member 71 extends to the outside of the sliding groove 74. The other end of the connecting rod 72 is connected to a group of clamping blocks 61 away from the connecting rod 72. The tension spring 73 is sleeved on the surface of the connecting rod 72. One end of the tension spring 73 is fixedly connected to one side surface of the trigger member 71 located in the sliding groove 74, and the other end is fixedly connected to the inner wall of the sliding groove 74.

[0040] It should be noted that the unlocking components 7 are staggered and can respectively drive the two groups of clamping blocks 61 to move relative to each other.

[0041] During actual use, the operator's thumb and index finger press the trigger member 71 simultaneously to drive the two groups of clamping blocks 61 to move away from each other. At this time, the inflation tube 3 can be taken out of the clamping groove.

[0042] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
