DETAILED DESCRIPTION

[0047] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention. Example

[0048] As attached Figure 1 To Attachment Figure 7 As shown:

[0049] The utility model provides a catheter fixing device, comprising a storage box 1;

[0050] Adhesive tape 2, wherein a plurality of adhesive tapes 2 are provided, and the plurality of adhesive tapes 2 are discretely fixedly connected to the front of the storage box 1;

[0051] A winding shaft 3, the winding shaft 3 is rotatably connected to the inside of the storage box 1;

[0052] A through hole 301 is provided, and the through hole 301 is provided at the center of the winding shaft 3;

[0053] The conduit 4 passes through the through hole 301, and the conduits 4 on the upper and lower sides of the through hole 301 are scattered and wound around the outside of the winding shaft 3, and the left and right ends of the conduit 4 pass through the left and right sides of the storage box 1;

[0054] A fixing block 12, the fixing block 12 is fixedly connected to the bottom of the storage box 1;

[0055] A fixing hole 1201, the fixing hole 1201 is provided inside the fixing block 12;

[0056] An automatic winding component is arranged inside the storage box 1.

[0057] Among them, the automatic winding components include:

[0058] The spiral spring 5, the inner end of the spiral spring 5 is coaxially fixedly connected under the winding shaft 3, and the outer end of the spiral spring 5 is fixedly connected to the storage box 1. The effect brought about is that the left and right ends of the catheter 4 are pulled outward at the same time, and the winding shaft 3 rotates, which can drive the spiral spring 5 to tighten.

[0059] Among them, the automatic winding component also includes:

[0060] A limit ratchet 6, which is coaxially fixedly connected to the winding shaft 3;

[0061] The limiting pawl 7 is rotatably connected to the top of the storage box 1, and the limiting pawl 7 is engaged with the limiting ratchet 6. The effect is that under the action of the ratchet and pawl transmission mechanism formed by the engagement of the limiting ratchet 6 and the limiting pawl 7, the winding shaft 3 can only rotate in one direction. Therefore, after loosening the left and right ends of the conduit 4, the winding shaft 3 will not rotate in the opposite direction under the rebound force of the spiral spring 5 itself, that is, the parts pulled out from the left and right ends of the conduit 4 will not retract into the storage box 1.

[0062] Among them, the automatic winding component also includes:

[0063] The return spring 701, the right end of the return spring 701 is fixedly connected to the left side of the rear end of the limit pawl 7, and the left end of the return spring 701 is fixedly connected to the inside of the storage box 1. The effect is that when the rear end of the limit pawl 7 is pulled to the left, the limit ratchet 6 and the limit pawl 7 will be disengaged, thereby driving the winding shaft 3 to rotate in the opposite direction under the rebound force of the spiral spring 5 itself, so that the part of the catheter 4 that is pulled out is retracted into the inside of the storage box 1.

[0064] The specific usage and function of this embodiment are as follows:

[0065] When it is necessary to use the catheter 4, the left and right ends of the catheter 4 are pulled outward at the same time, and the winding shaft 3 rotates. At this time, the volute spring 5 is tightened. After being pulled to a suitable length, the left and right ends of the catheter 4 are loosened. Under the action of the ratchet and pawl transmission mechanism formed by the engagement of the limit ratchet wheel 6 and the limit pawl 7, the winding shaft 3 can only rotate in one direction. Therefore, the winding shaft 3 will not rotate in the opposite direction under the force of the volute spring 5's own rebound, that is, the part pulled out of the left and right ends of the catheter 4 will not retract into the storage box 1, and then the adhesive tape 2 can be pasted on the patient's clothes or the patient's body; after use, the rear end of the limit pawl 7 is pulled to the left, which will make the limit ratchet wheel 6 disengage from the limit pawl 7, thereby driving the winding shaft 3 to rotate in the opposite direction under the force of the volute spring 5's own rebound, so that the part of the catheter 4 that is pulled out is retracted into the storage box 1. However, when the leaking part of the catheter 4 is felt to be too long, this method can also be used to retract a part of the catheter 4. It is simple and convenient to use, and avoids the inconvenience and squeezing caused by the leaking part of the catheter 4 being too long. Example

[0066] Based on the first embodiment, as shown in the attached Figure 1 To Attachment Figure 7 As shown, a fixing component is also included, and the fixing component is arranged under the fixing block 12.

[0067] The fixed components include:

[0068] A fixing belt 8, the fixing belt 8 is arranged under the fixing block 12;

[0069] Velcro hook surface 801, the Velcro hook surface 801 is arranged at the outer end of the fixing belt 8;

[0070] Velcro velvet 802, the Velcro velvet 802 is arranged on the inner end of the fixing belt 8, and its function is to wrap the fixing belt 8 around objects such as a hospital bed or an infusion stand, and then the fixing belt 8 can be fixed to these objects by sticking the Velcro hook surface 801 and the Velcro velvet 802 together.

[0071] The fixing components also include:

[0072] A fixing box 9, wherein the fixing box 9 is fixedly connected to the fixing belt 8;

[0073] A limit box 10, which is fixedly connected to the right side of the fixed box 9;

[0074] A latch 11, which is slidably connected to the interior of the fixing box 9;

[0075] A blocking piece 1101, the blocking piece 1101 is fixedly connected to the outside of the latch 11;

[0076] A limit spring 1102, the left end of the limit spring 1102 is fixedly connected to the right side of the baffle 1101, and the right end of the limit spring 1102 is fixedly connected to the inside of the limit box 10;

[0077] Pull ring 1103, the pull ring 1103 is fixedly connected to the right end of the pin 11, and its function is to pull the pin 11 to the right to drive the pin 11 to move to the right, and then insert the fixing block 12 into the fixing box 9, release the pull ring 1103, and under the action of the limit spring 1102, the blocking piece 1101 and the pin 11 return to their original positions, and the left end of the pin 11 is inserted into the fixing hole 1201, so that the fixing box 9 and the fixing block 12 are fixed together.

[0078] The specific usage and function of this embodiment are as follows:

[0079] When the storage box 1 is inconvenient to be too close to the patient's body, the fixing belt 8 can be wrapped around objects such as a hospital bed or an infusion stand, and then the fixing belt 8 can be fixed to these objects by sticking the Velcro hook surface 801 and the Velcro velvet surface 802 together. Then, pull the latch 11 to the right to drive the latch 11 to move to the right, and then insert the fixing block 12 into the fixing box 9, release the pull ring 1103, and under the action of the limit spring 1102, the baffle 1101 and the latch 11 return to their original positions, and the left end of the latch 11 is inserted into the fixing hole 1201, so that the fixing box 9 and the fixing block 12 are fixed together, which makes it convenient to keep the storage box 1 away from the patient's body, greatly enhancing its applicability.
