Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to a PICC maintenance and operation device. Background Technology

[0002] PICC (Peripherally Inserted Central Catheter) involves inserting a catheter into a vein in the arm, directly into a large vein near the heart. This avoids direct contact between chemotherapy drugs and the arm veins, and the rapid blood flow in the large vein quickly dilutes the chemotherapy drugs, preventing vascular irritation. PICC catheters can be left in place for up to a year and require professional maintenance every 7 days. During maintenance, the patient's upper limb is typically kept in a 90° abduction position. Since there is currently no dedicated PICC maintenance station to support the patient's upper arm, conventional office tables are commonly used. This makes the procedure very inconvenient for both patients and medical staff, taking 15-20 minutes and significantly impacting patient comfort. Especially in cases of limb contractures, assistance is needed to lift and stabilize the patient's forearm, adding an element of safety. Furthermore, long-term PICC maintenance can lead to occupational injuries such as lumbar muscle strain and frozen shoulder in medical staff. Utility Model Content

Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] Example

[0029] This embodiment provides a PICC maintenance and operation device, such as... Figure 1 and Figure 2 As shown, the support includes a first support plate 1, a second support plate 2, a third support plate 3, a first locking member 4, a second locking member 5, a limiting member 6, and a bracket 7. The second support plate 2 is fixed to the upper end of the bracket 7 and its two ends are rotatably connected to the first support plate 1 and the third support plate 3, respectively. The first locking member 4 can lock the first support plate 1 in a horizontal state, and the second locking member 5 can lock the third support plate 3 in a horizontal state, so that the upper surfaces of the first support plate 1, the second support plate 2, and the third support plate 3 form a support surface that fits against a horizontally extended arm. The first support plate 1 can rotate upward to a position perpendicular to the second support plate 2 and is fixed by the first locking member 4 to limit the forearm in a vertical state. The third support plate 3 can rotate downward to a position perpendicular to the second support plate 2 to allow the upper arm to suspend. The limiting member 6 is located at the end of the first support plate 1 and is used to limit the wrist to the first support plate 1 to keep the forearm in a vertical state.

[0030] The PICC maintenance device of this embodiment, by setting an upwardly rotatable first support plate 1, allows the patient's forearm to be supported in a vertical position during PICC maintenance, thereby helping the patient maintain arm stability during PICC maintenance. In particular, by setting a limiting member 6, the wrist of the patient with limb contracture can be limited on the first support plate 1, keeping the patient's forearm in a vertical position without the need for assistance from others, thus effectively improving the stability and safety of PICC maintenance for patients with limb contracture. In addition, by setting a downwardly rotatable third support plate 3, the upper arm can be suspended in the air, facilitating large-area disinfection around the upper arm insertion site without requiring the patient to lift the upper arm themselves or with the assistance of others.

[0031] To accommodate patients with different arm lengths, the position of the limiting member 6 on the first support plate 1 is adjustable. Preferably, as follows: Figure 2As shown, the limiting member 6 includes a strap 61, a hanging ring 62, and a hanging shaft 63. The hanging shaft 63 is fixed to one side of the first support plate 1, and its direction is the same as the length direction of the first support plate 1. The hanging ring 62 is located at one end of the strap 61 and is sleeved on the outer periphery of the hanging shaft 63. The hanging ring 62 can move along the hanging shaft 63 so that the position of the strap 61 and the wrist corresponds to each other, so as to limit the wrist of patients with different arm lengths. Compared with setting a telescopic structure on the first support plate 1 to adapt to different arm lengths, the movable limiting member 6 in this embodiment can make the operation more stable and faster.

[0032] To ensure patient comfort, the strap 61 should not be too tight between the strap and the patient's wrist. This is to prevent the strap from slipping down when the forearm is in a vertical position. Figure 2 As shown, the outer periphery of the hanging shaft 63 is provided with a plurality of first slots 631 that match the hanging ring 62, and the strap 61 can be limited to the first slots 631 by the hanging ring 62 and remain in the position corresponding to the wrist.

[0033] like Figure 2 As shown, the other end of the strap 61 is closably connected to the first support plate 1 via a buckle 64. For example, the buckle 64 is a Velcro or snap fastener. The snap fastener and snap fastener are respectively located at the other end of the strap 61 and the bottom of the first support plate 1. When the patient's position does not require the use of the limiting member 6, the strap 61 is located at the bottom of the first support plate 1 to ensure close support for the patient's forearm; when it is necessary to limit the patient's wrist, the buckle is opened, the strap 61 is wrapped upwards around the patient's wrist, and then the buckle is locked. The operation is simple, convenient, and highly flexible.

[0034] like Figure 3 As shown, the first locking element 4 includes a locking block 41 and a second locking groove 42 that matches the locking block 41. The locking block 41 is slidably connected to the bottom of the first support plate 1, and the second locking groove 42 is formed on the second support plate 2. The second locking groove 42 includes a horizontal groove 421 and a vertical groove 422. When the first support plate 1 provides horizontal support for the patient's forearm, one end of the locking block 41 is inserted into the horizontal groove 421, locking the first support plate 1 in a horizontal state. When it is necessary to assist the patient's forearm in maintaining a vertical state, the locking block 41 is slid at the bottom of the first support plate 1, pulling the locking block 41 out of the horizontal groove 421. The first support plate 1 is rotated upward to make the patient's forearm in a vertical state, and the locking block 41 is slid downward to insert one end of the locking block 41 into the vertical groove 422, thereby locking the first support plate 1 in a vertical state to assist the patient's forearm in maintaining the required vertical posture.

[0035] Preferred, such as Figure 3As shown, the first locking member 4 also includes a spring 43, which is located at the other end of the locking block 41 and fixed in the sliding groove of the first support plate 1 that matches the locking block 41, so as to push one end of the locking block 41 into the locking groove 42, making the structure of the first locking member 4 more stable and easier to operate.

[0036] like Figure 1 and Figure 4 As shown, the second locking member 5 includes a convex ring rotatably fitted onto the upper end of the bracket 7. A protrusion 51 is radially arranged on the outer periphery of the convex ring, and the protrusion 51 is used to lock the third support plate 3 in a horizontal state. In use, simply rotate the convex ring on the bracket 7 so that the protrusion 51 is located at or away from the bottom of the third support plate 3, thereby locking the third support plate 3 in a horizontal support state or allowing it to rotate downwards. The structure is simple and the operation is convenient.

[0037] To accommodate patients of different body types, arm lengths, and catheter placement sites, the stent 7y is equipped with a lifting mechanism to adjust the height of the support surface. For example, as shown... Figure 1 As shown, the support 7 includes upper and lower support rods. The opposite ends of the upper and lower support rods are provided with opposite external threads. The upper and lower support rods are connected by a sleeve 71. The sleeve has internal threads on both sides that match the external threads of the upper and lower support rods. By rotating the sleeve clockwise or counterclockwise, the height of the support surface can be adjusted, which not only improves the patient's comfort but also helps caregivers protect the back muscles and shoulder joints, reducing occupational injuries.

[0038] To further improve the efficiency of maintenance operations, such as Figure 1 As shown, the PICC maintenance operation device in this embodiment is also equipped with an instrument tray 8. The instrument tray 8 is rotatably connected to the bracket 7 and located below the second support plate 2. It is specifically used to place sterile items used during maintenance, which makes it easier for nursing staff to establish and protect the sterile area during operation.

[0039] The PICC maintenance and operation device in this embodiment is also equipped with casters with locking devices at the bottom, allowing for easy movement and flexible use. Furthermore, considering the need for direct intravenous infusion after maintenance, a retractable infusion stand can be installed on the bracket 7.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
