Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a fixation pad for preventing pressure injury to ECMO tubing. Background Technology
[0002] With the widespread application of extracorporeal membrane oxygenation (ECMO) technology in children, the prevention and treatment of related complications has become a focus of attention in the medical field. In clinical practice, ECMO tubing is often in prolonged contact with the patient's skin and soft tissues, easily leading to instrument-induced pressure injuries. This not only affects patient recovery but may also cause serious infections and further tissue damage. Currently available ECMO tubing fixation devices suffer from poor stability due to their materials and design, making them prone to displacement and affecting the safety of ECMO use. Therefore, a fixation pad to prevent instrument-induced pressure injuries to ECMO tubing is proposed to address the aforementioned problems. Utility Model Content
[0003] The purpose of this invention is to solve the problem that existing ECMO tubing fixing devices have poor tubing stability, are prone to displacement, and affect the safety of ECMO use. This invention proposes a fixing pad to prevent mechanical pressure damage to ECMO tubing.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A fixation pad for preventing pressure injury to ECMO tubing includes a fixation pad body, with two connecting brackets fixedly mounted on both sides of the fixation pad body, and two grooves symmetrically formed on the other side of the fixation pad body. The fixation pad also includes:
[0006] The pipe binding mechanism is installed on both sides of the fixing pad body. The pipe binding mechanism is used to bind and position two pipes passing through the two grooves. The pipe binding mechanism includes two first rotating rods and two second rotating rods. The first rotating rods and the second rotating rods are rotatably connected to the corresponding connecting frame. Both the first rotating rods and the second rotating rods are connected to the fixing mechanism. One end of the first rotating rod and one end of the second rotating rod are rotatably connected to the mounting frame. The same limiting band is fixedly installed on the two mounting frames at the same height. Two pressure pads are fixedly installed on one side of the limiting band, and one side of the pressure pads extends into the corresponding groove for pressing and limiting the pipes.
[0007] Furthermore, two limiting frames are fixedly installed on the other side of the fixing pad body, and the limiting straps pass through the corresponding limiting frames.
[0008] Furthermore, a fixation mechanism is connected to the tubing binding mechanism. The fixation mechanism is used to retract the tubing binding mechanism and simultaneously fix the fixation pad body to the patient's head.
[0009] Furthermore, the fixing mechanism includes a first connecting shaft and a second connecting shaft. The first connecting shaft is fixedly connected to the side of the two first rotating rods that are close to each other, and the second connecting shaft is fixedly connected to the side of the two second rotating rods that are close to each other. A fixing frame is rotatably sleeved on the first connecting shaft, and a through hole is provided on the fixing frame. A connecting plate is rotatably sleeved on the second connecting shaft, and a strap assembly is connected to the connecting plate. The strap assembly passes through the through hole and cooperates with the through hole.
[0010] Furthermore, the strap assembly includes a girdle fixedly installed on one side of the connecting plate, two support straps fixedly installed on the girdle, and the same connecting strap fixedly connected to the two support straps. The girdle, the two support straps and the connecting strap cooperate to secure the fixation pad body to the patient's head.
[0011] Furthermore, a fixing ring is fixedly installed on the belt, and one end of the belt passes through the fixing ring. A brake screw is threaded through the inner wall of one side of the fixing ring. The brake screw is used to position and brake the belt.
[0012] Furthermore, the fixing pad body includes an anti-slip support layer, a honeycomb mesh layer, and a skin-friendly layer that are fixed in sequence.
[0013] When using this fixation pad for preventing ECMO tubing pressure injury, first, pass the two tubings through their corresponding grooves. The side of the pad with the skin-friendly layer should be placed firmly against the patient's head. Then, pass the apron through the perforation and pull it. Pulling the apron causes the first and second connecting shafts to move via the fixation frame and connecting plate, which in turn rotates the two first and two second rotating rods. As the first and second rotating rods rotate, they pull and contract the connected limiting band, causing the pad to tend to move into the grooves. When the tubing is passed through the corresponding groove, the pressure pad can be used to press and limit the tubing. The surrounding strap, two support straps, and connecting strap work together to form a mesh belt effect. When the fixing pad is placed on the patient's head, the surrounding strap, two support straps, and connecting strap work together. By pulling the surrounding strap, the patient's head can be tied up, thus stably binding the fixing pad to the patient's head. Then, the brake screw can be rotated to move the brake screw. The brake screw and the fixing ring work together to position and clamp the surrounding strap, thus stably binding the surrounding strap to the patient's head.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The fixing pad for preventing instrumental pressure injury of ECMO tubing disclosed in this utility model, through the tubing binding mechanism, can simultaneously drive two first rotating rods and two second rotating rods to rotate by contracting the fixing mechanism, thereby contracting the limiting band and causing the pressure pad to tend to move into the groove. At this time, when the tubing is passed through the corresponding groove, the pressure pad can be used to press and limit the tubing.
[0016] 2. The fixing pad for preventing instrumental pressure injury of ECMO tubing disclosed in this utility model, through the fixing mechanism, can drive two first rotating rods and two second rotating rods to rotate respectively through the transmission cooperation of the first connecting shaft and the second connecting shaft when the strap assembly is contracted. At this time, the two limiting bands can be pulled to contract, thereby facilitating the binding and limiting of the two tubing.
[0017] 3. The fixation pad for preventing ECMO tubing instrument pressure injury disclosed in this utility model can tighten the two limiting straps by pulling the surrounding straps, thereby binding the two tubing. At the same time, the fixation pad body can be tied to the patient's head, thereby fixing the tubing and keeping it in a stable position so that the tubing will not easily shift.

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0025] Example 1, as Figures 1-3 The fixing pad shown includes a fixing pad body 1, with connecting brackets 2 fixedly mounted on the left and right sides of the fixing pad body 1 by welding or screws. Two grooves 7 are symmetrically formed on the outer sides of the front and rear sides of the fixing pad body 1. Multiple anti-slip protrusions can be provided on the inner walls of the grooves 7 to accommodate and position the ECMO tubing. A tubing binding mechanism is designed to achieve tubing binding and positioning. This mechanism includes two first rotating rods 18 and two second rotating rods 181, which are rotatably connected to their corresponding connecting brackets 2 via bearings. One end of each of the two first rotating rods 18 and two second rotating rods 181 is rotatably connected to a mounting bracket 3, which is welded or screwed onto the rotating rod. A limiting band 4 is fixedly mounted on the two mounting brackets 3 at the same height by sewing or adhesive. Two pressure pads 5 are fixedly mounted on one side of the limiting band 4 by sewing or strong adhesive. The pressure pads 5 are made of a soft and elastic material, and one side extends into the corresponding groove 7 to compress and limit the tubing.
[0026] A fixing mechanism was designed to retract the limiting band 4. This mechanism includes a first connecting shaft 8 and a second connecting shaft 81, which are fixedly connected to the adjacent sides of the two first rotating rods 18 and the two second rotating rods 181 by welding, respectively. A fixing bracket 11 is rotatably sleeved on the first connecting shaft 8, and the fixing bracket 11 has through holes drilled in it. A connecting plate 10 is rotatably sleeved on the second connecting shaft 81, and the connecting plate 10 is also fixedly mounted on the second connecting shaft 81 by welding or screws. A strap assembly is connected to the connecting plate 10.
[0027] The strap assembly includes a bandage 12 fixedly mounted on one side of the connecting plate 10. Two support straps 13 are sewn onto the bandage 12, and the ends of the two support straps 13 are fixedly connected to the same connecting strap 14 by sewing or adhesive. The bandage 12, the two support straps 13, and the connecting strap 14 cooperate to form a mesh belt effect, used to secure the fixation pad body 1 to the patient's head. A fixing ring 15 is fixedly mounted on the bandage 12, with one end of the bandage 12 passing through the fixing ring 15. A threaded hole is drilled on one inner wall of the fixing ring 15, and a braking screw 16 is threaded through it. The braking screw 16 is used to position and brake the bandage 12, ensuring that the fixation pad can be stably secured to the patient's head.
[0028] This application can be used in the field of medical device technology, or in other fields applicable to this application.
[0029] Example 2, an improvement on Example 1: The fixing pad for preventing instrumental pressure damage to ECMO tubing has two additional limiting brackets 6 fixed to one side of the groove 7 on the fixing pad body 1 by welding or screws. A limiting band 4 passes through the corresponding limiting bracket 6. In this way, the limiting bracket 6 can limit the limiting band 4, ensuring that the limiting band 4 remains connected to the fixing pad body 1, thus enabling the tubing to be bound and limited.
[0030] The fixation pad body 1 includes an anti-slip support layer 9, a honeycomb mesh layer 17, and a skin-friendly layer 19, which are fixed in sequence. The skin-friendly layer 19 is used to directly contact the patient's skin (increasing the microporous structure and combining it with an antibacterial coating to reduce moisture and bacterial growth from prolonged skin contact) and prevent allergies. The honeycomb mesh layer 17 is disposed between the anti-slip support layer 9 and the skin-friendly layer 19 to reduce the shear force of the ECMO tubing on soft tissue (adjusting the shear elastic modulus to distribute the pressure evenly). The anti-slip support layer 9 is used to stabilize the ECMO tubing.
[0031] When using this fixation pad to prevent pressure injury from ECMO tubing, the two ECMO tubing lines are passed through the two grooves 7 respectively. Then, the circumference strap 12, support strap 13, and connecting strap 14 are pulled to place the fixation pad body 1 on the patient's head. The circumference strap 12, the two support straps 13, and the connecting strap 14 work together to secure the fixation pad body 1 to the patient's head. After tightening the circumference strap 12, the brake screw 16 is rotated to move it. This allows the circumference strap 12 to be positioned and clamped using the cooperation of the brake screw 16 and the fixing ring 15. At this time, under the contraction action of the strap assembly, the two first rotating rods 18 and the two second rotating rods 181 are rotated through the transmission cooperation of the first connecting shaft 8 and the second connecting shaft 81, thereby pulling the two limiting straps 4 to contract. The pressure pads 5 on the limiting straps 4 then move into the grooves 7 to compress and limit the tubing, ensuring that the tubing will not damage the patient's skin due to movement or external force.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
