Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a fixing band for preventing contamination of indwelling needles. Background Art
[0002] An indwelling needle, also known as an intravenous indwelling catheter, is commonly used in intravenous infusion therapy. It is a soft and slender tube with a sharp needle at one end for piercing the skin and entering the vein, and the other end is bifurcated. One end is a catheter hub for connecting to an infusion tube or other medical devices, and the other end is a vent tube for maintaining internal and external air pressure. Once successfully inserted into the vein, the sharp puncture needle is removed, leaving only the catheter part in the vein. The indwelling needle can avoid repeated puncture of the vein and facilitate continuous infusion therapy by medical staff.
[0003] During the process of medical staff performing infusion operations on patients through indwelling needles, it is necessary to first disinfect the orifice of the catheter hub, and then remove the disposable scalp needle on the infusion set, and connect the infusion tube to the catheter hub through a screw thread. The inventor of this application found that during the use of indwelling needles, after medical staff disinfect the catheter hub, they need to fix it with one hand to prevent it from contacting the patient's skin or clothing and causing contamination. During the process of the medical staff removing the disposable scalp needle on the infusion set with the other hand, the infusion tube is prone to contact with the palm of the medical staff and cause contamination. At the same time, the hand fixing the catheter hub may also shake and contact the patient during the removal process due to inattention, which may cause contamination. Content of the Utility Model
[0004] In order to solve the problem that indwelling needles are prone to contamination when used by medical staff, the utility model provides a fixing band for preventing contamination of indwelling needles, and the specific technical solution is as follows:
[0005] A fixing band for preventing contamination of indwelling needles, comprising: a wrist restraint band, one side of the wrist restraint band being a functional surface; a fixing component provided on the functional surface, the fixing component forming a cavity for placing an indwelling needle; a arching component provided on the functional surface, the arching component including an upper bridge plate, the upper bridge plate being capable of forming a convex curve, and the convex curve being capable of lifting the cavity away from the functional surface.
[0006] Further, the arching component further includes: a lower bridge plate provided between the upper bridge plate and the functional surface, a slideway being formed on the surface of the lower bridge plate in contact with the upper bridge plate, the length direction of the slideway being parallel to the length direction of the upper bridge plate, and the projection of the slideway on the upper bridge plate being at least capable of covering the upper bridge plate. The upper bridge plate can form a convex curve by sliding along the slideway. The arching component further includes a traction band with one end connected to the left end of the upper bridge plate. The length of the traction band is A, the length of the upper bridge plate is B, and the length of the slideway is C, where B < A < C. The traction band can pull the left end of the upper bridge plate to slide along the slideway on the surface of the lower bridge plate to form a convex curve. The material of the upper bridge plate is plastic.
[0007] Preferably, a fixed buckle is formed at the end of the slideway, and the fixed buckle can fix the other end of the traction belt.
[0008] Preferably, the width of the traction belt is E, the cross-section of the slideway is concave-like, the width of the opening of the slideway is F, the inner width of the slideway is H, the width of the upper bridge plate is G, F < E, F < G, E < H.
[0009] Preferably, the fixing assembly further includes a fixing member disposed on the upper bridge plate. When a retention needle is placed in the cavity, the fixing member can apply pressure to the surface of the retention needle to restrict the movement of the retention needle.
[0010] Preferably, there is an included angle between the center line of the cavity and the length direction of the wrist restraint belt.
[0011] Preferably, the two ends of the wrist restraint belt are detachably connected.
[0012] From the above technical solutions, the present utility model has the following beneficial effects:
[0013] In the present utility model, by providing a cavity for placing a retention needle, the retention needle can be fixed on the top surface of the upper bridge plate. Secondly, by setting the left end of the upper bridge plate to slide along the slideway, the distance between the two end points of the upper bridge plate is reduced, so that the upper bridge plate can form a convex curve, and the vertex of the convex curve is lifted away from the cavity and away from the functional surface, so that the cavity with the retention needle can be kept at a certain distance from the patient's wrist, thereby reducing the risk of the retention needle being contaminated, and at the same time releasing the hands of medical staff for further operations.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "inside", "outside", "upper", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0019] As Figures 1 to 2 shown, the embodiments of the present utility model include: a wrist restraint band 1, one side of the wrist restraint band 1 being a functional surface; a fixing assembly 2 provided on the functional surface, the fixing assembly 2 forming a cavity 22 for placing an indwelling needle 4; and an arching assembly 3 provided between the functional surface and the fixing assembly 2, the arching assembly 3 including an upper bridge plate 32 which can form a convex curve, and the convex curve can lift the cavity 22 away from the functional surface.
[0020] Specifically, the wrist restraint band 1 is worn on the patient's wrist, and the surface in contact with the patient's wrist is a contact surface. The material of this contact surface is selected as skin-friendly materials such as cloth (conventional technology) to avoid discomfort for the patient during long-term wearing. The other side of the wrist restraint band 1 is a functional surface, and the arching assembly 3 is connected to the functional surface by means of gluing or sewing. The arching assembly 3 includes an upper bridge plate 32, and the distance between the two ends of the upper bridge plate 32 can be close to make it arch into a convex curve. At the same time, the upper part of the upper bridge plate 32 is fixedly connected to the fixing assembly 2 by means of gluing or sewing. There are two cavities 22 formed on the upper surface of the fixing assembly 2 for placing the two bifurcated ports of the indwelling needle 4. On the one hand, the convex curve formed by the upper bridge plate 32 arching upward can lift the indwelling needle 4 placed in the cavity 22 away from the functional surface of the wrist restraint band 1, so that when the medical staff uses the indwelling needle 4 to connect the infusion tube, the indwelling needle 4 can be directly fixed at a certain distance from the patient's wrist, avoiding contamination of the indwelling needle 4 and facilitating the medical staff to remove the disposable scalp needle of the infusion set.
[0021] Furthermore, the connection mode of the two ends of the wrist restraint band 1 is a detachable connection, which can facilitate the medical staff to remove the embodiments of the present utility model from the patient's wrist and improve the care efficiency. Secondly, the structure of this detachable connection can be the adhesion between magic tapes, or the buckling between male and female buttons, and the wrist restraint band 1 can adjust the distance between the two ends according to the circumference of the patient's wrist, so as to make it fully fit the patient's wrist.
[0022] Furthermore, the fixing component 2 further includes a fixing member 21 disposed on the upper bridge plate 32. When the indwelling needle 4 is placed in the cavity 22, the fixing needle can apply pressure to the surface of the indwelling needle 4 to restrict the movement of the indwelling needle 4.
[0023] Specifically, in the embodiment of the present utility model, the fixing member 21 uses an elastic buckle to provide pressure to the indwelling needle 4. The indwelling needle 4 enters the inner cavity 22 of the buckle through the opening above the buckle. The protrusion in front of the buckle is used to restrict the bifurcation opening of the indwelling needle 4 and limit its forward and backward movement to prevent the indwelling needle 4 from falling off. Secondly, the fixing member 21 can also adopt the structure of an openable hairpin, and the spring elasticity of the hairpin provides pressure to the indwelling needle 4. Secondly, the fixing member 21 can also adopt the structure of an elastic band. The middle of the elastic band is separated to form two cavities 22 for placing the indwelling needle 4. The elastic band restricts the movement of the indwelling needle 4, so that the indwelling needle 4 can be stably fixed on the patient's wrist without using a sterile transparent dressing or tape to fix the indwelling needle 4, avoiding damage to the skin of the patient's wrist.
[0024] Furthermore, there is an included angle between the center line of the cavity 22 and the length direction of the wrist restraint band 1.
[0025] Specifically, in the embodiment of the present utility model, the included angle is preferably 45°. This included angle can make the pipe orifice of the catheter seat of the indwelling needle 4 deviate from the patient's wrist and then face the medical staff, which is convenient for the medical staff to disinfect the catheter seat and connect the infusion tube, improving the work efficiency of the medical staff.
[0026] Furthermore, the arching component 3 further includes a lower bridge plate 31 disposed between the upper bridge plate 32 and the functional surface. A slideway 33 is formed on the surface of the lower bridge plate 31 in contact with the upper bridge plate 32. The length direction of the slideway 33 is parallel to the length direction of the upper bridge plate 32, and the projection of the slideway 33 on the upper bridge plate 32 can at least cover the upper bridge plate 32. The upper bridge plate 32 can form a convex curve by sliding along the slideway 33.
[0027] The left end of the slideway 33 is aligned with the left end of the upper bridge plate 32, and the right end of the slideway 33 extends beyond the right end of the upper bridge plate 32. When the right end of the upper bridge plate 32 is fixed on the upper surface of the lower bridge plate 31, the left end of the upper bridge plate 32 slides along the slideway 33 on the upper surface of the lower bridge plate 31, so that the distance between the two ends of the upper bridge plate 32 is reduced, and then the upper bridge plate 32 bulges upward to form a convex curve. As described above, this convex curve can lift the indwelling needle 4 off the upper surface of the lower bridge plate 31. It should be noted that the length of the slideway 33 can be equal to the length of the lower bridge plate 31, that is, the left and right ends of the slideway 33 can be through, and of course, the left and right ends of the slideway 33 can also be non-through, as long as it does not prevent the left end of the upper bridge plate 32 from sliding along.
[0028] Further, the arching component 3 further includes a traction belt 34 with one end connected to the left end of the upper bridge plate 32. The length of the traction belt 34 is A, the length of the upper bridge plate 32 is B, and the length of the slideway 33 is C. B < A < C. The traction belt 34 can pull the left end of the upper bridge plate 32 to slide along the slideway 33 on the surface of the lower bridge plate 31 to form a convex curve.
[0029] Specifically, the traction belt 34 drives the left end of the upper bridge plate 32 to slide, and the traction belt 34 moves within the slideway 33. Therefore, the length of the slideway 33 is the largest. The length of the traction belt 34 cannot exceed the slideway 33, otherwise the other end of the traction belt 34 cannot be fixed at the end of the slideway 33, and the convex curve of the upper bridge plate 32 cannot be stably maintained. The length of the traction belt 34 should also be greater than the length of the upper bridge plate 32, otherwise there is no extra part of the traction belt 34 for medical staff to use to pull the traction belt 34. The traction belt 34 is the power source for reducing the distance between the two end points of the upper bridge plate 32.
[0030] Further, the material of the upper bridge plate 32 is selected as plastic.
[0031] Specifically, while forming a convex curve, plastic can maintain a certain bearing capacity at its top for carrying the indwelling needle 4.
[0032] Further, a fixed buckle 35 is formed at the end of the slideway 33, and the fixed buckle 35 can fix the other end of the traction belt 34.
[0033] Specifically, the left end of the traction belt 34 pulls the left end of the upper bridge plate 32 to slide to the right. When the upper bridge plate 32 forms a convex curve that meets the requirements, the right end of the traction belt 34 can fix the position of the left end of the upper bridge plate 32 through the fixed buckle 35, so that the upper bridge plate 32 can stably maintain the convex curve, facilitating medical staff to release their hands for the next operation.
[0034] Further, the width of the traction belt 34 is E, the cross-section of the slideway 33 is concave-like, the width of the opening of the slideway 33 is F, the internal width of the slideway 33 is H, and the width of the upper bridge plate 32 is G. F < E, F < G, E < H.
[0035] Specifically, the traction belt 34 being wider than the opening of the slideway 33 but narrower than the inside of the slideway 33 enables the traction belt 34 to always slide within the slideway 33. The slideway 33 can limit the outward movement of the traction belt 34. The slideway 33 being narrower than the upper bridge plate 32 can prevent the upper bridge plate 32 from falling into the slideway 33. Furthermore, if the upper bridge plate 32 falls into the slideway 33, the slideway 33 can also limit the movement of the upper bridge plate 32 into the lower bridge plate 31, improving the stability of the movement of the upper bridge plate 32 in forming a convex curve.
[0036] Further, the connection method at both ends of the wrist restraint band is a detachable connection.
[0037] Specifically, the connection mode at both ends of the wrist restraint band can be Velcro connection or button connection, and it can adjust the binding strength with the patient's wrist.
[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
[0039] The technologies, shapes, and structures not described in detail in the present invention are all well-known technologies.
