Description

Technical Field

[0001] This utility model relates to a protective restraint device for PICC lines, belonging to the field of medical device technology. Background Technology

[0002] Peripherally Inserted Central Catheter (PICC) is a key technology in modern clinical intravenous therapy. Its core principle is to precisely insert the catheter tip into the superior vena cava via a peripheral vein in the upper limb (usually the basilic vein, median cubital vein, or cephalic vein), effectively avoiding vascular damage caused by repeated punctures. However, catheter displacement due to upper limb movement during patient catheterization has become a critical challenge in clinical nursing. Currently, various restraint devices are widely used by those skilled in the art to address this issue, but existing restraint devices suffer from the following three major technical drawbacks:

[0003] Firstly, traditional dressings and fixation bandages often use a flat, close-fitting design. During the patient's elbow flexion and extension, the fabric's insufficient elasticity leads to a curling rate as high as 63.2%.

[0004] Secondly, the lack of a visual monitoring window for fixation devices makes it easy to delay the early identification of signs of infection at the puncture site (such as local redness, swelling, and effusion) in daily care. According to statistics from the US CDC, this leads to a 17% increase in the incidence of catheter-related bloodstream infections (CRBSI).

[0005] Third, the method of fixing the drug infusion port is relatively rigid. When connecting the infusion device, the dressing needs to be removed repeatedly, resulting in an average of 2.3 unnecessary catheter disturbances per day. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a PICC pipeline protective restraint device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A PICC pipeline protective restraint device, comprising:

[0009] A restraint sleeve for restraining the PICC tube A on the upper arm, wherein an inner elastic band is sewn inside one end of the restraint sleeve, and a fixing hook, Velcro strip and a first magnetic buckle are sewn on the surface of the restraint sleeve.

[0010] A visible piece sewn to the restraint sleeve, a connecting strip sewn on one side surface of the visible piece, a second magnetic snap sewn onto the connecting strip and magnetically attached to the first magnetic snap, and a tightening assembly sewn onto the visible piece, the tightening assembly including a Velcro strap sewn to the visible piece and a pull-out elastic band passing through the Velcro strap;

[0011] A restraint glove is sewn to one end of a restraint sleeve, and a tightening buckle is sewn onto one end of the restraint glove.

[0012] Preferably, one end of the restraint sleeve extends into the inside of the restraint glove, and a loop is sewn onto the outer side of the restraint sleeve near the fastening buckle.

[0013] Preferably, the annular belt has an annular groove inside, and the surface of the annular belt has a hole communicating with the groove.

[0014] Preferably, the belt groove of the ring belt is provided with an adjustable tension band, which passes through the belt hole.

[0015] Preferably, the visible sheet is a dome structure.

[0016] Preferably, the surface of the restraint sleeve has a viewing opening covered by a viewing sheet.

[0017] Preferably, hook holes with an elliptical orthographic projection are provided at both ends of the pull-out elastic band.

[0018] Preferably, one end of the fixing hook is a "U"-shaped hook, and one end of the fixing hook passes through the hook hole.

[0019] Preferably, the restraint sleeve is provided with an adjustable telescopic component.

[0020] Preferably, the telescopic component is a bellows structure.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] (1) This utility model has been repeatedly improved based on clinical use. The restraint sleeve is used to restrain the PICC tube on the patient's upper arm. It is elastic, can adapt to the three-dimensional shape of the patient's arm, and has excellent fit and extensibility. While restraining the patient's range of motion, it increases comfort and necessary joint mobility. The inner elastic band is sewn into one end of the restraint sleeve, and the surface is sewn with a fixing hook, Velcro strip and a first magnetic snap. Combined with the design of the restraint sleeve, it can effectively prevent the edge from rolling up during use and achieve a good fixation effect.

[0023] (2) The visual film connected to the restraint sleeve in this utility model has the following advantages: First, the visual film is designed with a dome structure, allowing for all-around observation of the puncture site. As a monitoring window, it facilitates timely monitoring of the patient's puncture site, enabling timely treatment of any signs of infection and preventing delays in treatment. Second, after the visual film covers the PICC tube, the first and second magnetic buckles are connected by magnetic adsorption, and the Velcro strap and Velcro strip are bonded together. The end of the pull-out elastic band is fitted onto one end of the fixing hook, keeping the visual film stable and preventing accidental opening of the visual film during use, which could lead to infection at the puncture site. It also effectively prevents unnecessary disturbance to the catheter. In addition, the visual film can be opened at any time for operation when connecting the infusion device, making operation convenient. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 3This utility model provides a protective restraint device for PICC lines, including a restraint sleeve 3 for restraining the PICC line A on the upper arm 1. One end of the restraint sleeve 3 has an inner elastic band 31 sewn inside, and its surface is sewn with a fixing hook 34, a Velcro strip 33, and a first magnetic buckle 32. The positions of the fixing hook 34, Velcro strip 33, and first magnetic buckle 32 can be adjusted according to actual needs, and the shape and size of the first magnetic buckle 32 and the second magnetic buckle 42 can also be adjusted according to actual requirements. The restraint sleeve 3 is worn on the upper arm 1, with the end near the inner elastic band 31 featuring a loose, ring-shaped elastic design for easy placement on the outside of the upper arm 1. The inner elastic band 31 effectively increases the elasticity and prevents the restraint sleeve 3 from shifting or curling during use.

[0031] The visual film 4, sewn to the restraint sleeve 3, can be made of transparent plastic or other transparent and clinically acceptable materials, such as a 0.2mm thick medical polyurethane film with 92% light transmittance. The visual film 4 can also be designed as a dome structure to allow for 360-degree shadowless observation of the puncture area. The visual film 4 has an openable design, facilitating puncture procedures on the upper arm 1, dressing changes for the PICC line, and observation of the skin condition at the puncture site. A connecting strip 41 is sewn to one side of the visual film 4, and a second magnetic snap 42 is sewn onto the connecting strip 41. This second magnetic snap 42 is connected to the first magnetic snap 32 via magnetic attraction, ensuring the stability of the visual film 4 during use. Furthermore, a tightening assembly is sewn onto the visual film 4, consisting of a Velcro strap 7 sewn to the visual film 4 and a pull-out elastic band 8 passing through the Velcro strap 7. By stretching and pulling the elastic band 8, the Velcro strap 7 can be tightly bound to the visible piece 4, preventing the visible piece 4 from loosening, thereby effectively restraining the PICC tube A.

[0032] This invention also includes a restraint glove 2 sewn to one end of the restraint sleeve 3, with a tightening buckle 21 sewn to one end. Wearing the restraint glove 2 on the palm effectively restricts hand movement, working in conjunction with the restraint sleeve 3 to achieve comprehensive restraint of the upper limb arm 1. The tightening buckle 21 further enhances the restraining effect. The restraint glove 2, restraint sleeve 3, and visible panel 4 in this invention are all made of elastic transparent material, such as silicone.

[0033] In one embodiment of this invention, one end of the restraint sleeve 3 extends into the interior of the restraint glove 2. A loop 5 is sewn onto the outer side of the restraint sleeve 3 near the tightening buckle 21. The loop 5 has an annular groove inside and a hole a communicating with the groove on its surface. An adjustable elastic band 6 is provided within the groove of the loop 5, passing through the hole a. By adjusting the adjustable elastic band 6 within the loop 5, the tightness can be precisely controlled, thus ensuring that the cup-shaped opening of the restraint sleeve 3 near the restraint glove 2 is in an adjustable elastic restraint state to accommodate the needs of different patients.

[0034] In one embodiment of this utility model, a viewing port b covered by a viewing sheet 4 is provided on the surface of the restraint sleeve 3 to facilitate observation of the skin at the puncture site and the PICC tube A.

[0035] In another embodiment of this utility model, both ends of the pull-out elastic band 8 are provided with hook holes that are elliptical in orthographic projection. One end of the fixing hook 34 is in the shape of a "U"-shaped hook. After this end passes through the hook hole, both ends of the pull-out elastic band 8 are stretched outward, and its end is sleeved on the outside of the fixing hook 34, thereby limiting the pull-out elastic band 8 and preventing it from being overstretched or loosened.

[0036] The working principle and usage process of this utility model are as follows:

[0037] When performing PICC surgery on the upper limb arm 1 and inserting the PICC tube A, first put the restraint sleeve 3 on the upper limb arm 1, and at the same time put the restraint glove 2 on the palm. The inner elastic band 31 can increase the elasticity and tension, effectively preventing the restraint sleeve 3 from shifting or curling.

[0038] Open the viewing window 4. At this time, the skin of the upper limb arm 1 restrained by the restraint sleeve 3 is partially exposed, which facilitates the upper limb PICC surgery. Insert one end of the PICC tube A into the skin.

[0039] After the puncture is completed, the visual sheet 4 is covered, so that the first magnetic buckle 32 and the second magnetic buckle 42 are connected by magnetic attraction, thereby keeping the visual sheet 4 stable.

[0040] Both the Velcro binding strap 7 and the Velcro strip 33 are sewn with adhesive Velcro, which are then bonded together to further enhance the stability of the viewing film 4.

[0041] The two ends of the pull-out elastic band 8 are stretched outwards and their ends are fitted onto the outside of one end of the fixing hook 34, thereby limiting the pull-out elastic band 8 and increasing the stability of the visible sheet 4.

[0042] The adjustable elastic band 6 within the ring 5 can be adjusted to suit different patients. Specifically, pulling the adjustable elastic band 6 outward from the ring 5 tightens the ring 5; pulling the ring 5 outward further loosens it. Thus, the cup-shaped opening of the restraint sleeve 3 near the restraint glove 2 is in an adjustable, elastic restraint state to meet the needs of different patients.

[0043] like Figure 4 As shown, in another embodiment, the restraint sleeve 2 is provided with an adjustable telescopic component 35, the main function of which is to adjust the length according to the length of the upper limb arm 1 of different patients. A structure that can achieve this function in the prior art can be selected. In this embodiment, an accordion structure is selected.

[0044] In summary, this invention features a visual upper limb restraint design for observing the puncture site. The restraint sleeve 3 and restraint glove 2 restrain the upper limb arm 1. When the visual panel 4 is opened, the skin of the upper limb arm 1 restrained by the restraint sleeve 3 is partially exposed, facilitating upper limb PICC surgery and daily observation. When it is necessary to restrain the PICC tube A, the visual panel 4 is closed, and the magnetic attraction between the first magnetic buckle 32 and the second magnetic buckle 42, as well as the adhesive connection between the Velcro strap 7 and the Velcro strip 33, combined with the pull-out elastic band 8 being fitted onto the fixing hook 34, ensures that the visual panel 4 remains stable and effectively protects the PICC tube.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
