Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a PICC catheter maintenance hand support. Background Art

[0002] During PICC catheter maintenance, the patient's arm is placed on a hand rest to maintain it in a fixed position, and then the PICC catheter is maintained. However, since PICC catheterization is typically performed at the basilic vein above the elbow joint, the disinfection range during PICC catheter maintenance is 10-20 cm. If the outer side of the arm is not suspended after disinfection, it can be difficult for the disinfectant on the skin to dry, affecting the observation of the catheter position and causing the PICC catheter to slip out. This is also detrimental to the patient's comfort and operator convenience. When the patient is wearing long-sleeved clothing, during PICC catheter maintenance, the patient's sleeve and / or the chest portion of the clothing will move closer to the PICC catheter installation location as the patient moves. Generally, after the sleeve and / or the chest portion of the clothing move closer to the PICC catheter installation location, the sleeve and / or the chest portion of the clothing will come into contact with the disinfectant on the patient's arm, causing the disinfection to fail and contaminating the patient's clothing. In severe cases, the sleeve and / or the chest portion of the clothing can hook onto the PICC catheter, causing the PICC catheter to be pulled, slipped, or broken. Therefore, there is a need to improve the safety of PICC catheter maintenance.

[0003] In the prior art, for example, utility model CN206675670U is a PICC maintenance hand rest. In this patent, the first support portion is used to support the upper arm, and the second support portion is used to support the forearm. It can simultaneously fix and support the upper arm and forearm of the patient undergoing PICC maintenance, and can adjust the support height and position according to the patient's needs. However, when the patient wears long-sleeved clothes, the patient's sleeves and / or the chest part of the clothes will move closer to the installation position of the PICC catheter as the patient moves; generally, this will cause the disinfection to fail and the patient's clothes to be contaminated; in severe cases, it will cause the PICC catheter to be pulled, slipped or broken.

[0033] Examples, such as Figure 1 As shown,

[0034] A PICC catheter maintenance hand support includes a support plate 1, one end of which is provided with a support pad 2, the support pad 2 being used to elevate the patient's catheter arm so that the disinfected skin area on the patient's catheter arm is suspended in the air, and further includes:

[0035] a baffle 3, which is arranged at the other end of the support plate 1 and is used to prevent the chest part of the patient's clothes from moving closer to the PICC catheter;

[0036] The hook assembly 4 is arranged on the baffle 3, and the hook assembly 4 is used to hook and fix the sleeves of the patient's clothes.

[0037] When maintaining the PICC catheter, the patient places his forearm on the support pad 2, and the support pad 2 limits the movable position of the patient's arm to facilitate medical staff to maintain the PICC catheter. After the patient places his forearm on the support pad 2, the patient's chest is against the baffle 3, and the baffle 3 blocks the chest part of the patient's clothes from moving close to the PICC catheter. Then, the sleeves of the patient's clothes are hooked and fixed by the hook component 4, and the movable position of the sleeves is limited by the hook component 4 to prevent the sleeves from moving close to the PICC catheter. In this technical solution, the chest part of the patient's clothes is blocked and the sleeves of the patient's clothes are hooked and fixed, which prevents the sleeves or / and the chest part of the clothes from moving close to the installation position of the PICC catheter, thereby improving the safety of the PICC catheter maintenance process.

[0038] As a preferred embodiment, Figure 1-Figure 2 As shown, the support pad 2 is provided on the support plate 1 in the following manner:

[0039] Slide grooves 11 are respectively provided on both sides of the support plate 1, and a U-shaped seat 21 is integrally provided at the bottom end of the support pad 2. The inner side of the U-shaped seat 21 is clearance-matched with the support plate 1, and sliders 22 are also integrally provided on the inner walls on both sides of the U-shaped seat 21. The sliders 22 are slidably connected in the slide grooves 11, so that the position of the support pad 2 relative to the baffle 3 can be adjusted according to the length of the patient's arm by sliding adjustment along the support plate 1 through the U-shaped seat 21.

[0040] Different patients have different arm lengths, and the position of the support pad 2 relative to the baffle 3 needs to be adjusted according to the patient's arm length to effectively prevent the sleeves and / or the chest part of the clothes from approaching the installation position of the PICC catheter; therefore, a slide groove 11 is provided on both sides of the support plate 1, and a U-shaped seat 21 is integrally provided at the bottom end of the support pad 2. The U-shaped seat 21 is slidably connected to the slide groove 11 through a slider 22, so that the support pad 2 can be slid and adjusted along the support plate 1 according to the patient's arm length to effectively prevent the sleeves and / or the chest part of the clothes from approaching the installation position of the PICC catheter; and the inner side of the U-shaped seat 21 is clearance-matched with the support plate 1, and the sliding connection of the slider 22 and the slide groove 11 ensures the connection stability between the support pad 2 and the support plate 1.

[0041] As a preferred embodiment, Figure 2As shown, a handle bolt 23 is also connected through the U-shaped seat 21 , and the end of the handle bolt 23 abuts against the support plate 1 by being screwed. The handle bolt 23 is used to fix the position of the U-shaped seat 21 on the support plate 1 .

[0042] After the support pad 2 is slidably adjusted along the support plate 1 according to the patient's arm length, when the patient's forearm is placed on the support pad 2, the support pad 2 is in an movable state. When the patient's arm moves, the support pad 2 will cause displacement changes, which is not conducive to medical staff to perform maintenance operations; therefore, a handle bolt 23 is connected through the U-shaped seat 21, and when the support pad 2 is slidably adjusted along the support plate 1 according to the patient's arm length, the handle bolt 23 is loosened so that the end of the handle bolt 23 does not abut against the support plate 1, and the U-shaped seat 21 is in an movable state; after the support pad 2 is slidably adjusted into place according to the patient's arm length, the handle bolt 23 is tightened so that the end of the handle bolt 23 abuts against the support plate 1, and the U-shaped seat 21 is in an immovable state.

[0043] As a preferred embodiment, Figure 3 As shown, it also includes a baffle 5, on which a plurality of connecting hooks 51 are fixedly connected, and on the baffle 3 a plurality of connecting rings 31 are fixedly connected, and the connecting hooks 51 are hooked with the connecting rings 31. The baffle 5 is used to prevent the disinfectant from dripping and contaminating the patient's clothes and / or pants.

[0044] During the maintenance of the PICC catheter, disinfectants are used. After the disinfectants drip and contaminate the patient's clothes and / or pants, they are difficult to clean. Therefore, a blocking cloth 5 is connected to the baffle 3 through the cooperation of the connecting ring 31 and the connecting hook 51. The patient's forearm is placed on the support pad 2, and after the sleeves of the patient's clothes are hooked and fixed, the connecting hook 51 is hooked and connected to the connecting ring 31, so that the blocking cloth 5 is blocked above the patient's upper arm and / or sleeve, so as to prevent the disinfectant from dripping and contaminating the patient's clothes and / or pants, thereby reducing the burden on the patient.

[0045] As a preferred embodiment, Figure 1 and Figure 4 As shown, the hook assembly 4 includes two limiting hooks 41, which are connected to the baffle 3. The two limiting hooks 41 are located on both sides of the support plate 1. The limiting hooks 41 are used to hook the patient's sleeves to avoid contaminating the skin disinfection area.

[0046] When maintaining the PICC catheter, the patient's sleeve is rolled up to the upper arm, and the patient's forearm is placed on the support pad 2, and then the sleeve is hooked with the two limit hooks 41. The limit hooks 41 limit the movable position of the sleeve to prevent the sleeve from approaching the installation position of the PICC catheter.

[0047] Further, if Figure 4-Figure 5 As shown, the limiting hook 41 is connected to the baffle 3 in the following manner:

[0048] A limiting slot 32 is provided on the baffle 3, and both sides of the tail of the limiting hook 41 are hinged in the limiting slot 32. A connecting port 42 is provided in the middle position of the tail of the limiting hook 41, and a connecting shaft 43 is integrated in the connecting port 42. A torsion spring 44 is passed through the connecting shaft 43, and one end of the torsion spring 44 abuts against the limiting hook 41, and the other end of the torsion spring 44 abuts against the slot wall of the limiting slot 32.

[0049] The arm widths of different patients are different, and the position of the limit hook 41 needs to be able to be adaptively adjusted to correspond to different arm widths; therefore, the tail of the limit hook 41 is hinged in the limit slot 32, and a torsion spring 44 is provided between the limit hook 41 and the limit slot 32. Through the elastic support of the torsion spring 44, the heads of the two limit hooks 41 are tilted toward the middle position and moved closer to each other; after the patient's forearm is placed on the support pad 2, the two limit hooks 41 are respectively opened to both sides to adapt to the arm widths of different patients. The torsion spring 44 applies a slight elastic force, so that the heads of the two limit hooks 41 are against the patient's arm. The elastic force applied by the torsion spring 44 is relatively small and will not cause pinching of the patient's arm.

[0050] Further, such as Figure 1 As shown, the support pad 2 is configured as an arc-shaped support pad, and a flexible backrest cushion Ⅰ 24 is further provided on the inner side of the arc-shaped support pad.

[0051] The height of the support pad is set to 10-15 cm. The support pad is used to raise the patient's arm for tube placement, so that the skin in the disinfection area is suspended in the air to prevent contamination.

[0052] The arc-shaped support pad can fit the patient's forearm, and the flexible cushion Ⅰ24 arranged on the inner side of the arc-shaped support pad contacts the patient's forearm, thereby enhancing the patient's comfort during the PICC catheter maintenance process through shape adaptation and flexible buffering.

[0053] Further, such as Figure 1 As shown, the baffle 3 is configured as an arc-shaped baffle, and a flexible cushion II 33 is further provided on the inner side of the arc-shaped baffle.

[0054] The curved baffle can fit the patient's chest, and the flexible cushion II 33 provided on the inner side of the curved baffle contacts the patient's forearm, thereby enhancing the patient's comfort during the PICC catheter maintenance process through shape adaptation and flexible cushioning.

[0055] As a preferred embodiment, the length of the support plate 1 is set to 15-30 cm. By setting the length of the support plate 1 to 15-30 cm, sufficient clearance is ensured between the baffle 3 and the support pad 2, while limiting the overall length and reducing the space occupied, making it easier to store and move.

[0056] As a preferred embodiment, the length of the baffle 3 is set to 20 cm. By setting the length of the baffle 3 to 20 cm, the blocking effect on the chest part of the patient's clothes is guaranteed, and the space occupied by the baffle 3 is greatly limited, so that it is easy to store and move.

[0057] The above description is merely a preferred embodiment of the utility model and is not intended to limit the technical solution of the utility model. Those skilled in the art will readily appreciate that the utility model is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the technical solution of the utility model shall be included within the scope of protection of the utility model.
