Abstract
Description
Technical Field
[0001] This application relates to the field of PICC placement auxiliary equipment technology, and in particular to a PICC placement treatment vehicle with a limb fixation device. Background Technology
[0002] PICC placement, or peripherally inserted central catheter placement, involves inserting a catheter into a vein in the arm and then directly into a large vein near the heart. This avoids direct contact between chemotherapy drugs and the veins in the arm. In addition, the high blood flow in the large vein can quickly dilute the chemotherapy drugs and prevent them from irritating the blood vessels.
[0003] When inserting a PICC line, the patient's arm needs to be extended. During routine PICC insertion, a medical assistant is required to lift the patient's arm on the side of insertion. This not only consumes medical and nursing resources but may also cause discomfort to the patient, increasing the patient's tension and affecting the patient's cooperation in the insertion. It can also worsen vascular conditions, such as causing vasospasm and vasoconstriction.
[0004] The prior art discloses a utility model patent with publication number CN215021359U, which discloses a PICC bedside catheter placement auxiliary device. This device uses a foldable support plate to support the patient's arm. However, this prior art has the following drawbacks: First, medical equipment and medications that need to be used are usually placed on the top of the vehicle beforehand. Before the support plate is folded, it is located on the top of the vehicle, which affects the advance preparation of medications. Second, the head of the hospital bed is usually against the wall. When using this device, the drawer side needs to be away from the wall, but the support plate can only be folded to one side. This means that during use, the support plate can only be folded to provide auxiliary support for the right arm. If catheter placement is needed for the left arm, the drawer needs to be facing the wall, making the drawer unusable. However, when placing a PICC catheter, the left or right arm needs to be selected based on the patient's history of arm injury, surgical history, and dominant arm. Therefore, the solution of this prior art does not take into account the selection of the left or right arm when placing a PICC catheter. Utility Model Content

[0039] Example
[0040] This embodiment provides a PICC placement treatment cart with a limb fixation device, see reference. Figure 1 As shown, it includes a vehicle body 1, a limb fixation component 2, and a vertical adjustment device 3.
[0041] The vehicle body 1 has a centrally located empty layer 11, within which a connecting column 12 extending vertically is provided. That is, the vehicle body 1 comprises a first part and a second part, connected by the connecting column 12. The first part is located above the empty layer 11, and the second part is located below the empty layer 11. The first part can be a plate-like structure, forming a medication placement platform 13 at its top. The medication placement platform 13 is used to pre-load the medications and medical equipment required for PICC line insertion.
[0042] Specifically, refer to Figure 2 As shown, the limb fixation assembly 2 includes a support plate 21, a pull-out plate 22, and a limiting member 23. The support plate 21 includes a base plate 211 and connecting portions 212. Connecting portions 212 are provided on both sides of the base plate 211, and the connecting portions 212 protrude upward along the surface of the base plate 211. Each connecting portion 212 has through holes 213 corresponding to connecting posts 12. There are four connecting posts 12, distributed at the four corners of the vehicle body 1. Correspondingly, there are four through holes 213 on each connecting portion 212, with two through holes 213 on each connecting portion 212. The connecting posts 12 pass through the corresponding through holes 213, allowing the connecting portion 212 to be movably connected to the connecting post 12 in the vertical direction.
[0043] The connecting part 212 has a horizontally extending guide groove 214 on its side. The two sides of the pull-out plate 22 are respectively inserted into the guide groove 214, so that the pull-out plate 22 moves horizontally and connects with the connecting part 212. The two ends of the connecting part 212 are respectively provided with limiting members 23, and the two ends of the pull-out plate 22 are respectively provided with limiting holes 221 that are adapted to the limiting members 23. The pull-out plate 22 can be pulled outward from both ends of the connecting part 212, and then inserted into the corresponding limiting hole 221 by the corresponding limiting member 23 to restrict the position of the pull-out plate 22. This allows the pull-out plate 22 to be pulled out from the corresponding side regardless of whether the treatment cart is placed on the left or right side of the bed, so that the left or right arm can be placed accordingly.
[0044] Continue to refer to Figure 1 As shown, the vertical adjustment device 3 is located below the support plate 21. Specifically, one end of the vertical adjustment device 3 is connected to the second part of the vehicle body 1, and the other end is connected to the support plate 21. The height of the support plate 21 can be adjusted by the vertical adjustment device 3, thereby adjusting the pull-out plate 22 to a suitable height for the patient. In this embodiment, the vertical adjustment device 3 can be a hydraulic cylinder or an electric push rod, or other mechanisms capable of vertical adjustment.
[0045] The PICC insertion treatment cart with a limb fixation device provided in this embodiment can pull out pull-out plates 22 from both sides of the cart. The pull-out plates 22 can be pulled out from the corresponding direction depending on whether the left or right arm is selected during PICC insertion, thereby supporting the corresponding arm and accommodating both left and right arm options. The limb fixation component 2 is located in the hollow layer 11 in the middle of the cart body 1. The pull-out plates 22 are pulled out during use, without occupying space on the top of the cart, facilitating the preparation of medications and medical equipment in advance.
[0046] Specifically, the bottom of the guide groove 214 is flush with the surface of the base plate 211, and the bottom of the pull-out plate 22 abuts against the upper surface of the base plate 211. This ensures that the entire bottom surface of the pull-out plate 22 abuts against the upper surface of the base plate 211, providing more comprehensive support for the pull-out plate 22 and improving its stability.
[0047] Specifically, refer to Figure 4As shown, the limiting component 23 includes a base 231, a rotating handle 232, and a limiting rod 233. The base 231 is mounted on the connecting part 212. The rotating handle 232 is connected to the limiting rod 233. The limiting rod 233 is threaded to the base 231 and passes through the connecting part 212 into the guide groove 214, allowing the limiting rod 233 to be inserted into the limiting hole 221 to restrict the relative movement of the pull-out plate 22 and the connecting part 212. A through hole is provided at the position of the guide groove 214 of the connecting part 212, allowing the limiting rod 233 to pass through the base 231 and then through the hole into the guide groove 214. When it is necessary to pull out the pull-out plate 22, the limiting rod 233 is separated from the limiting hole 221 by rotating the rotating handle 232. After the pull-out plate 22 is pulled out, rotating the rotating handle 232 allows the limiting rod 233 to be inserted into the limiting hole 221, positioning the pull-out plate 22 and ensuring its stability.
[0048] Specifically, a pressure plate 234 is connected to the limiting rod 233. The pressure plate 234 is located above the pull-out plate 22 and is used to press the pull-out plate 22 tightly onto the bearing plate 21. (Refer to...) Figure 3 As shown, when the limit rod 233 is rotated into the limit hole 221, the pressure plate 234 presses onto the pull plate 22, pressing the pull plate 22 onto the bearing plate 21. The pressure plate 234 and the bearing plate 21 clamp the pull plate 22, ensuring the stability of the pull plate 22.
[0049] Specifically, refer to Figure 5 As shown, the limiting rod 233 includes a first rod body 235 and a second rod body 236. One end of the first rod body 235 has an assembly section, forming a first stepped surface 237 between the assembly section and the first rod body 235. The end of the assembly section has a threaded hole. The end of the second rod body 236 has a threaded section, forming a second stepped surface 238 between the threaded section and the first rod body 235. The pressure plate 234 is sleeved on the assembly section, and the threaded section is connected to the threaded hole, causing the first stepped surface 237 and the second stepped surface 238 to clamp the pressure plate 234. When assembling the pressure plate 234, the first rod body 235 can be inserted into the guide groove 214 first, then the pressure plate 234 can be sleeved on the assembly section, and finally the second rod body 236 can be installed. This allows the pressure plate 234 to be installed on the limiting rod 233, placing the pressure plate 234 inside the guide groove 214.
[0050] Specifically, the guide groove 214 is provided with a plurality of rotating wheels 215 arranged along the length of the guide groove 214, and the rotating wheels 215 press against the pull-out plate 22. By setting the rotating wheels 215, the process of pulling out the pull-out plate 22 is made smoother. Furthermore, when the pull-out plate 22 is pulled out to the correct position, the pressure plate 234 presses the pull-out plate 22 firmly against the support plate 21, avoiding the upward pressure generated by the cantilever of the pull-out plate 22 and the arm on the rotating bearing of the rotating wheels 215, and preventing the rotating bearing from being damaged by excessive pressure.
[0051] Specifically, the pull-out plate 22 is equipped with restraint straps 222 at both ends. The two restraint straps 222 correspond to the left or right arm respectively, and can restrain the patient's arm on the pull-out plate 22 to prevent arm movement during catheter insertion and thus avoid interference. The restraint straps 222 can be secured using a fastener or Velcro.
[0052] Specifically, continue to refer to Figure 1 As shown, the second part includes a drawer 14, which has a nine-compartment layout. Medicines and medical supplies can be stored in the drawer 14.
[0053] Specifically, the second part has a trash can 15 at its bottom. The bottom of the trash can 15 is suspended, and two rotating shafts 17 are connected to both sides. The rotating shafts 17 are connected to the second part. The rotating shafts 17 are located on the center line of the side of the trash can 15, and the bottom of the trash can 15 has a counterweight 16. Because the rotating shafts 17 are located on the center line of the side of the trash can 15, the counterweights 16 can keep the trash can 15 with its opening facing upward. When the trash can 15 needs to be used, the bottom of the trash can 15 can be pushed by foot, causing the trash can 15 to rotate around the rotating shafts 17, thereby turning the opening of the trash can 15 to face outward. After throwing away the trash, the foot can be removed, and the trash can 15 will automatically rotate back to the closed state.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
