[0024] Example 1

[0025] Reference Figure 1-4This utility model provides an embodiment of a portable PICC measuring ruler, comprising a storage housing 1 and a short-side measuring ruler 2 and a long-side measuring ruler 3. A winding wheel 4 and a pin 5 are provided in the middle of the storage housing 1. Multiple sets of short-side measuring rulers 2 and long-side measuring rulers 3 connected by dotted grooves 6 are provided on the inner side of the winding wheel 4. The short-side measuring rulers 2 and long-side measuring rulers 3 are connected and fixed by connectors 7. The length of the short-side measuring ruler 2 is 10cm, and the length of the long-side measuring ruler 3 is 50-60cm. Both the short-side measuring ruler 2 and the long-side measuring ruler 3 are made of flexible transparent plates. An outlet end 8 is provided at the bottom end of the storage housing 1, and a bottom shell 9 is provided on the bottom surface of the outlet end 8.

[0026] The bottom surface of the short side measuring ruler 2 is provided with an adhesive layer 10, and the two ends of the long side measuring ruler 3 are provided with dotted grooves 6. The short side measuring ruler 2 and the long side measuring ruler 3 are folded and placed inside the storage housing 1 through the connector 7.

[0027] The top surface of the storage housing 1 is provided with a groove 11. The storage housing 1 is cylindrical and is composed of two symmetrical housings. The inner edge surfaces are respectively provided with corresponding slots and plugs for docking and fixing. The winding wheel 4 is fixed to the middle of the inner side of one side of the storage housing 1. The middle of the winding wheel 4 is provided with a slot corresponding to the plug 5.

[0028] The storage housing 1 and the winding wheel 4 are assembled together. The winding wheel 4 is also assembled together with the short side measuring ruler 2 and the long side measuring ruler 3. The short side measuring ruler 2 and the long side measuring ruler 3 are wound into the inside of the winding wheel 4 in a ring. The storage housing 1 and the outlet end 8 are integrated. A rectangular outlet is provided on the inside of the outlet end 8. Both are made of silicone material.

[0029] The outlet end 8 and the bottom shell 9 are fixedly connected. The bottom shell 9 is a rectangular shell made of silicone material. A storage groove 12 is provided inside the bottom shell 9. The storage groove 12 is U-shaped. An alcohol swab 13 is provided inside the storage groove 12. The alcohol swab 13 includes a packaging bag and a swab.

[0030] Specifically, its structure comprises a storage housing 1, a short-side measuring scale 2, a long-side measuring scale 3, a winding wheel 4, a pin 5, a dotted groove 6, a connector 7, an outlet end 8, a bottom shell 9, an adhesive layer 10, a groove 11, a storage slot 12, and alcohol swabs 13, forming a portable PICC measuring scale. Multiple integrated PICC measuring scales, consisting of the short-side measuring scale 2 and the long-side measuring scale 3, are placed inside the storage housing 1 and wound up by the winding wheel 4. The flexible layer of the short-side measuring scale 2 and the long-side measuring scale 3 enables the winding effect, and the connector 7, being made of the same material as the short-side measuring scale 2 and the long-side measuring scale 3, allows for bending. The short-side measuring scale 2 and the long-side measuring scale 3 are then used... To measure the patient's arm circumference and ensure the appropriate size of the selected puncture catheter, the connector 7 allows the short-side measuring ruler 2 and the long-side measuring ruler 3 to rotate, enabling medical staff to take accurate measurements. A pin 5 is inserted into the middle of the take-up reel 4 to fix the take-up reel 4 and simultaneously close the two outer shells of the housing 1 for fixed positioning. When medical staff need to use the PICC measuring ruler, they pull it out from the outlet end 8 via the dotted groove 6. At this time, the take-up reel 4 releases the PICC measuring ruler until the dotted groove 6 is torn, allowing a complete PICC measuring ruler to be removed. The connector 7 facilitates the rotation and adjustment of the short-side measuring ruler 2 and the long-side measuring ruler 3 for medical staff to use in measurements. The outlet end 8 is used to pull out the PICC measuring scale. Because the connector 7 is located at the end of the short side measuring scale 2 and the long side measuring scale 3, it has a certain protrusion. When the PICC measuring scale is pulled out from the outlet end 8, the dotted groove 6 is close to the connector 7, which will pull out the connector 7 end of the next PICC measuring scale. The outlet end 8 is made of silicone and has a certain degree of flexibility. It can pull out the connector 7 under pressure, but it is not easy to insert it. At this time, the connector 7 of the next PICC measuring scale is used to block the outlet end 8 to prevent dust from entering. The bottom shell 9 is used to store alcohol wipes 13. The adhesive layer 10 is used to fix the connection when the short side measuring scale 2 and the long side measuring scale 3 are folded. The adhesive layer 10 is linear. The design facilitates the separation of the short-side measuring ruler 2 and the long-side measuring ruler 3 without damaging them. After separation, the measuring rulers can be rotated for use. The groove 11 allows easy opening of the two sides of the storage housing 1 to add the measuring rulers inside the winding wheel 4 for future use. The storage slot 12 is used to stack multiple alcohol wipes 12. The alcohol wipes 13 can be used to disinfect the measuring rulers before use and can also be used to disinfect other medical tools. This design allows the portable PICC measuring ruler system to effectively carry multiple measuring rulers for use, ensuring efficient storage, immediate access, and reduced risk of cross-infection. It also facilitates disinfection for medical staff, effectively improving overall work efficiency.

[0031] Working principle: When in use, open the two sides of the storage housing 1 through the groove 11, place the PICC measuring scale that has been wound up on the winding wheel 4, pull the connector 7 of the end of the PICC measuring scale to the outside of the outlet end 8, and then place the half of the housing with the pin 5 into the middle of the winding wheel 4, and fix the storage housing 1 together. This allows for the storage of multiple PICC measuring scales for easy use. Then, insert the alcohol swabs 13 into the storage slot 12 for use by medical staff when needed. When measurement is required, pull out the PICC measuring ruler connector 7 at the outlet end 8 until it reaches the dotted groove 6. Then pull out the connector 7 of the next PICC measuring ruler. The outermost PICC measuring ruler can be peeled off along the dotted groove 6 for use. When using the PICC measuring ruler, the adhesive layer 10 will only stick to the bottom edge of the short side measuring ruler 2. The short side measuring ruler 2 and the long side measuring ruler 3 can be separated by a slight pull and rotated and adjusted with the connector 7. After that, take out an alcohol swab 13 from the bottom of the storage slot 12, tear open the packaging, and then disinfect the PICC measuring ruler before measurement.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
