Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a PICC placement and fixation device. Background Technology

[0002] PICC (Peripherally Inserted Central Catheter) placement involves inserting a flexible, relatively long catheter into a vein above the elbow and advancing it along the vein until the tip reaches a major blood vessel, specifically a central vein near the heart. It is widely used for patients requiring long-term intravenous infusion, chemotherapy, nutritional support, and other treatments. PICC placement offers advantages such as minimal invasiveness, low infection rate, and broad applicability, and has gradually become a commonly used intravenous therapy method in clinical practice.

[0003] After a PICC line is implanted in a patient, a fixation wing and a connector are provided in the shoulder area. The fixation wing and the connector are connected by an extension tube. In order to facilitate the patient's normal movement and to prevent the PICC line from being pulled, medical staff currently fix it by applying a transparent dressing. However, when medical staff perform actions such as administering intravenous infusions, they can easily pull the fixation wing when inserting or removing the connector. Since the fixation wing is directly connected to the tubing inside the patient's body, this greatly increases the risk of the PICC line shifting. Utility Model Content

[0004] In view of this, the present invention provides a PICC catheter fixation device, which aims to better fix the external catheter and prevent the PICC catheter from shifting.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A PICC placement fixation device is characterized by comprising an arm sleeve for securing it to a patient's arm, the arm sleeve having a window for exposing the patient's arm, a first support fixed to one side of the middle portion of the arm sleeve for securing a PICC placement connector, a spacer provided within the window, and a second support fixed to the spacer for securing a PICC placement fixing wing.

[0007] With the above structure, the connector and fixation wing of the PICC tube are fixed by two support bases respectively, which can ensure that the connector and fixation wing will not easily shake when the patient moves. In addition, when medical staff need to plug or unplug the connector, the design of the secondary support base can ensure that the fixation wing will not be easily pulled, thereby ensuring that the tube placed in the body will not shift in position.

[0008] Preferably, the second support base has two locking posts at its top, arranged side by side, with an installation gap between them. This installation gap is used to secure the side wings of the fixed wing. This structure further ensures that the drag force on the connector prevents the fixed wing from moving, thus effectively preventing PICC tube misalignment.

[0009] Preferably, the arm sleeve has two transverse straps extending along its length and a longitudinal strip perpendicularly connected between the middle sections of the two transverse straps. The middle sections of the two transverse straps and the two longitudinal strips form the window, and the two ends of the spacer are respectively fixed between the two longitudinal strips. This structure reduces the contact area with the patient's arm, ensuring breathability for the patient's arm.

[0010] Preferably, the arm sleeve is fitted with an anti-slip pad on one side that is in close contact with the patient's arm. This structure increases the friction between the arm sleeve and the patient's arm, preventing the arm sleeve from shifting and causing the PICC line to deviate.

[0011] Preferably, the anti-slip pad is a silicone pad. This structure increases the friction between the arm sleeve and the arm while ensuring patient comfort.

[0012] Preferably, a transparent dressing is adhered to the outer surface of the window. This structure effectively secures the externally inserted PICC line, preventing it from shifting and causing displacement of the internally inserted PICC line.

[0013] Preferably, the two ends of the transverse strap are elastic bands, and the two ends of the transverse strap are connected as one piece by Velcro. This structure allows the arm sleeve to be more stably fixed to the patient's arm.

[0014] Preferably, the armband surface has several breathable micropores. This structure makes the armband more breathable, thus ensuring wearing comfort.

[0015] Preferably, the partition divides the window into an upper region and a lower region, with the first support seat positioned on the outer side of the upper region. This structure creates a hollow area between the two supports, further ensuring that the drag force on the connector prevents the fixed wing from moving, thus effectively preventing PICC tube displacement.

[0016] Preferably, the spacer strip, transverse binding strip, and longitudinal strip are integrally formed. This structure makes the entire arm sleeve structure more stable.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The PICC tube fixing device provided by this utility model uses two support seats to fix the connector and fixing wing of the PICC tube respectively. Even if the connector is accidentally pulled, within a certain range of force, the pulling force will not be transmitted to the fixing wing on the second support seat, thereby reducing the risk of the tube being displaced or accidentally pulled out.

[0019] 2. The window is divided into upper and lower areas by a partition strip, and two support bases are respectively set at both ends of the upper area. This creates a hollow area between the connector and the fixed wing. When medical staff need to plug or unplug the connector, the hollow area design further ensures that the fixed wing will not be easily pulled, thereby ensuring that the internal tube will not shift position.

[0027] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0028] like Figure 3As shown, after a PICC line is implanted, a connector 8 and a fixation wing 9 are pre-installed on the patient's arm 7. The connector 8 and the fixation wing 9 are connected by an extension tube 10. A flexible tube 11 is connected to the end of the fixation wing 9 furthest from the extension tube 10, and the distal end of the flexible tube 11 extends into the patient's body. The connector 8 has a trumpet-shaped structure, with the extension tube 10 connected to its smaller end and the other end open outwards. The fixation wing 9 includes a rod-shaped fixation rod 9a and side wings 9b extending outwards from the middle of the fixation rod 9a. In conventional technology, only the fixation wing 9 is adhesively fixed to the upper arm; accidental pulling of the connector 8 can easily lead to accidental tube pull-out and insertion displacement. The PICC insertion fixation device provided in this embodiment is used to fix the entire part exposed outside the patient's body, namely the connector 8 and the fixation wing 9.

[0029] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, a PICC placement and fixation device includes an arm sleeve body 1, which is used to fix it to the patient's arm 7. The arm sleeve body 1 has a window 1a formed on it, which exposes the patient's arm 7. The connector 8, the fixing wing 9, the extension tube 10, and the hose 11 are all exposed through the window 1a. A first support base 2 is fixedly installed on one side of the middle part of the arm sleeve body 1. The connector 8 is fixedly clipped into the first support base 2. A spacer 1b is provided in the window 1a. A second support base 3 is fixedly installed on the spacer 1b. The fixing wing 9 is fixedly clipped into the second support base 3.

[0030] With this design, the connector 8 and the fixed wing 9 are fixedly connected by the first support 2 and the second support 3 respectively. Even if the connector 8 is accidentally pulled, within a certain range of force, the pulling force will not be transmitted to the fixed wing 9 on the second support 3, thereby reducing the risk of displacement of the internal tube or accidental tube removal.

[0031] Furthermore, such as Figure 6 and Figure 7 As shown, the top of the second support base 3 has two locking posts 3a arranged side by side, with an installation gap 3b formed between them. The fixing rod 9a is fitted into the two locking posts 3a, and the side wing 9b is positioned within the installation gap 3b. In this embodiment, the structure of the first support base 2 is the same as the overall structure of the second support base 3, and will not be described again here.

[0032] When medical staff exert a large pulling force on connector 8, extension tube 10 can be pulled first to offset part of the pulling force. When the pulling force is too large, causing extension tube 10 to start pulling fixed wing 9, since side wing 9b is set within the two installation gaps 3b, fixed wing 9 cannot be pulled, thus ensuring that the tube 11 inside the patient's body will not be pulled and will not shift.

[0033] like Figure 2 As shown, the arm sleeve body 1 has two transverse straps 1c extending along its length and a longitudinal strip 1d vertically connected between the middle sections of the two transverse straps 1c. The middle sections of the two transverse straps 1c and the two longitudinal strips 1d form a window 1a. The two ends of a spacer strip 1b are respectively fixed between the two longitudinal strips 1d. In this embodiment, the transverse straps 1c, the longitudinal strips 1d, and the spacer strip 1b are integrally formed. This design reduces the contact area between the arm sleeve body 1 and the patient's arm 7, ensuring the breathability and comfort of the patient's arm 7.

[0034] like Figure 2 As shown, in this embodiment, the partition 1b divides the window 1a into an upper region 1a1 and a lower region 1a2, and the first support 2 is located on the outside of the upper region 1a1. By setting the two support 2 at the two ends of the upper region 1a1 respectively, a hollow area is formed between the connector 8 and the fixing wing 9. When medical staff need to plug or unplug the connector, the hollow area design further ensures that the fixing wing 9 will not be easily pulled, thereby ensuring that the internal tube will not shift position.

[0035] Furthermore, such as Figure 2 As shown, an anti-slip pad 6 is fixedly installed on one side of the arm sleeve 1 that is in close contact with the patient's arm 7. The anti-slip pad 6 is a silicone pad. The anti-slip pad 6 can increase the friction between the arm sleeve 1 and the patient's arm 7, ensuring that the arm sleeve 1 will not shake after being strapped to the patient's arm 7, thereby ensuring that the PICC tube is stably installed without displacement. In addition, the design of the silicone pad can also ensure the comfort of wearing the arm sleeve 1.

[0036] In this embodiment, when the connector 8 and the fixed wing 9 are fixedly installed on the first support base 2 and the second support base 3 respectively, a transparent adhesive tape 4 is also attached to the outer surface of the window 1a. Specifically, the transparent adhesive tape 4 is attached to the lower area 1a2. This design allows the hose 11 connected to the fixed wing 9 to be fixedly installed, further preventing the PICC tube from shifting.

[0037] In this embodiment, the two ends of the transverse binding strip 1c are elastic bands, such as... Figure 2 As shown, Velcro 5 is installed on the upper surface of one end of the arm sleeve body 1 and the lower surface of the other end. With this design, the arm sleeve body 1 is more stably tied to the patient's arm 7 through the design of the elastic band and Velcro 5.

[0038] In addition to being secured by Velcro 5, the components can also be secured by magnetic attraction or pin buckles. In this embodiment, Velcro 5, anti-slip pad 6, first support 2, and second support 3 are all secured to the arm sleeve body 1 by sewing. Alternatively, they can be secured to the arm sleeve body 1 by adhesive.

[0039] In this embodiment, the surface of the arm sleeve 1 is also formed with several breathable micropores to further ensure the breathability of the entire arm sleeve 1.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
