Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a vascular access system and a limb vascular access fixing device. Background Art

[0002] Treatment of patients by establishing vascular access has been widely used in clinical practice. The most common one is temporary vascular access, such as indwelling needles, intravenous indwelling catheters, etc. Compared with traditional infusion needles, temporary vascular access can reduce the number of punctures, prolong the indwelling time, protect blood vessels, reduce the pain of patients, and improve the work efficiency of medical staff.

[0003] After the existing vascular access is punctured into the blood vessel, in order to prevent it from moving, the exposed vascular access is usually fixed with fixing devices such as dressings and bandages to prevent it from falling out or nursing safety hazards. However, there are two situations with the existing fixing devices. One is that only the retention head of the vascular access is fixed, and the exposed parts such as the catheter, infusion interface, and infusion clamp are not well fixed, resulting in the exposed parts often rubbing against bedding, clothing, etc. If it acts on pediatric patients, it is easy to cause grabbing and pulling, which increases the probability of safety hazards. The other is to wrap and fix all the exposed parts of the vascular access, but this fixing method makes the steps cumbersome and difficult to operate for nursing staff when performing infusion operations, which increases the workload of nursing staff, and the fixing device that wraps the infusion clamp and infusion connector needs to be frequently disassembled and fixed during the infusion operation, which is very likely to cause the curling, falling off, and non-stickiness of the fixing device, which greatly reduces the service life and greatly increases the consumption of the fixing device.

[0044] by Figure 1 Taking the angle of view shown as a reference, the second fixing part 30 is located at the lower side of the first fixing part 20 and the operating part 40. The right edge of the second fixing part 30 is fixed on the second surface 102, the left edge of the second fixing part 30 is provided with a self-adhesive structure (such as Velcro, self-adhesive dressing, etc.), and the corresponding part on the second surface 102 is also provided with a self-adhesive structure (such as Velcro, self-adhesive dressing, etc.), and the second fixing part 30 fixes the infusion clamp and the catheter through the self-adhesive structure at the left edge of the second fixing part 30 and the self-adhesive structure at the corresponding part on the second surface 102.

[0045] In some other optional embodiments, the upper edge and / or lower edge of the second fixing portion 30 may also be provided with a self-adhesive structure, and correspondingly, the corresponding portion on the second surface 102 is also provided with a self-adhesive structure to strengthen the firmness of the connection between the second fixing portion 30 and the second surface 102. The second fixing portion 30 may also be provided so that the left edge is fixed to the second surface 102, and the other edge is at least partially detachably connected to the second surface 102. The second fixing portion 30 may also be provided so that one side edge is fixed to the second surface 102, and all other portions are detachably connected to the second surface 102 through a self-adhesive structure. It should be understood that the material of the second fixing portion 30 can achieve the above-mentioned self-adhesive effects by adopting the prior art.

[0046] In some other optional embodiments, the shapes of the first fixing portion 20 and the second fixing portion 30 can also be set to various shapes such as circular, elliptical, polygonal, irregular, etc.

[0047] In some other optional embodiments, the first fixing portion 20 and / or the second fixing portion 30 may also be detachably connected to the second surface 102 as a whole via a self-adhesive structure.

[0048] It is important to understand that Figure 1 The dotted lines in FIG. 1 only represent the corresponding parts of the second surface 102 and the first fixing portion 20 and the second fixing portion 30 , and do not represent any openings, parts, etc.

[0049] In some embodiments, the operating portion 40 is disposed on the body 11 and includes an operating port 41 that extends from the first surface 101 to the second surface 102 . The exposed portion of the retention head is disposed in the operating port 41 and extends from the operating port 41 to the outside of the second surface 102 .

[0050] In this embodiment, the operation opening 41 is a narrow and long incision, and its shape can be almond-shaped, oval-shaped, rectangular, etc., or can be a slit. In some specific embodiments, the length of the operation opening 41 is about 3 cm.

[0051] In some embodiments, at least a portion of the main body 10 is transparent to form an observation window 111. The observation window 111 is located above or around the operation port 41 and is used to observe the situation at the puncture site of the indwelling head to prevent bleeding and other situations that cannot be detected.

[0052] In this embodiment, the observation window 111 is formed on the body 11 and is rectangular in shape and is located above the operation port 41 .

[0053] In some other optional embodiments, the observation window 111 may also be in an irregular shape such as a circle or a polygon. It should be understood that the material of the observation window 111 can achieve the above effect through the existing technology.

[0054] In some other optional embodiments, only one fixing portion may be provided, which may simultaneously cover the areas covered by the first fixing portion 20, the second fixing portion 30 and the operating portion 40, so as to simultaneously fix the infusion clamp, the catheter and the infusion connector, and may also cover the operating port 41, so as to further reduce the exposure of the vascular indwelling pathway after the setting is completed.

[0055] In some embodiments, a waterproof strip is further disposed on the periphery of the first surface 101 .

[0056] During specific use, it is first necessary to pass the exposed part of the blood vessel retention passage after puncture through the operation port 41 to the outside of the second surface 102. At this time, the retention head and the catheter connected to it that pass through the operation part 40 extend downward, and part of the catheter and the infusion clamp provided on the catheter extend downward to the part corresponding to the second fixing part 30. By bonding the self-adhesive part on the left edge of the second fixing part 30 to the corresponding self-adhesive part on the second surface 102, the infusion clamp and the corresponding part of the catheter are clamped between the second fixing part 30 and the second surface 102, thereby playing a fixing role and preventing the exposure from being touched or grabbed.

[0057] Furthermore, while the infusion clamp and part of the catheter are fixed by the second fixing portion 30, the catheter located at the second fixing portion 30 is bent to the left and extended upward, so that the other end of the catheter and the infusion connector connected thereto are located on the left side of the operation port 41, i.e., the position corresponding to the first fixing portion 20. By bonding the self-adhesive portion on the right edge of the first fixing portion 20 to the corresponding self-adhesive portion on the second surface 102, the catheter at the end and the infusion connector connected thereto are clamped between the first fixing portion 20 and the second surface 102, thereby fixing the infusion connector and preventing it from being exposed to touch or grabbing.

[0058] It should be understood that the bending direction of the catheter needs to be compatible with the relative position between the first fixing portion 20 and the operating portion 40 .

[0059] When infusion is required, the first fixing part 20 only needs to be opened, the infusion tube is connected to the infusion connector, and then the first fixing part 20 is closed again, and the connected infusion connector is clamped between the first fixing part 20 and the second surface 102. When the flow rate needs to be adjusted, the second fixing part 30 only needs to be opened, and after adjusting the flow rate to a suitable flow rate through the infusion clip, the second fixing part 30 is closed again, and the adjusted infusion clip and the catheter are clamped between the second fixing part 30 and the second surface 102.

[0061] In this embodiment, no observation window is set on the main body 10b. The operating port 41b of the operating portion 40b is rectangular, and its size covers the operating port 41 and the observation window in the first embodiment, so that the operating port 41b can be used to pass the retention head and serve as an observation window.

[0062] The operating portion 40b further includes a covering portion 42b for covering the operating port 41b. The covering portion 42b is in a sheet shape in this embodiment, and at least a portion of the covering portion 42b is detachably connected to the second surface 102b.

[0065] In this embodiment, the covering portion 42b is made of a transparent, breathable existing material to ensure that the puncture situation can be observed through the operation port 41b to prevent the blood vessel indwelling passage from turning over, falling out, etc.

[0066] In some embodiments, the covering portion 42b is slightly larger than the operating port 41b to ensure complete coverage of the operating port 41b.

[0067] In some other optional embodiments, the covering portion 42b may also be circular, elliptical, polygonal, irregular, etc. The covering portion 42b may not completely cover the operation port 41b, but only cover the lower end of the operation port 41b, so that only the part where the indwelling head is inserted is covered and protected during use, and the upper opening is exposed as an observation window for observation.

[0068] Figure 3 The limb vascular access fixation device 1c in the third embodiment of the utility model is shown. The differences between the limb vascular access fixation device 1c and the limb vascular access fixation device 1 in the first embodiment include:

[0069] A portion of the periphery of the first fixing portion 20c is fixed on the second surface 102, and a first receiving opening is defined between the remaining portion of the periphery and the second surface 102c. The infusion connector can be received between the first fixing portion 20c and the second surface 102c through the first receiving opening.

[0070] Specifically, in this embodiment, the left edge, the upper edge and the right edge of the first fixing portion 20c are all fixed on the second surface 102c, and a first receiving opening is defined between the lower edge and the second surface 102c, so that a shape similar to a pocket with an opening downward is formed between the first fixing portion 20c and the second surface 102c, and the infusion connector is inserted upward between the first fixing portion 20c and the second surface 102c and taken out during infusion.

[0071] In some embodiments, part of the periphery of the second fixing portion may also be fixed on the second surface 102c, and a second receiving opening is defined between the remaining periphery and the second surface 102c, and the infusion clamp is received between the second fixing portion and the second surface 102c through the second receiving opening.

[0076] In this embodiment, the portion of the second surface 102d covered by the first fixing portion 20d overlaps with the portion of the second surface 102d occupied by the operating portion 40d, so that when the first fixing portion 20d covers the second surface 102d, it also covers the operating portion 40d.

[0077] Specifically, the size of the first fixing portion 20d in the length direction of the main body 10d is matched with the size of the second fixing portion 30d in the length direction of the main body 10d. The operating portion 40d includes an operating port 41d, which is narrow and long, and its length is matched with the size of the first fixing portion 20d in the length direction of the main body 10d, and is slightly smaller than the size of the first fixing portion 20d in the length direction of the main body 10d. The longer operating port 41d makes the position of the indwelling head on the operating port 41d adjustable, and thus the infusion connector can be flexibly adjusted to be located on the left or right side of the indwelling head, which is convenient for medical staff to choose operation.

[0078] In some embodiments, the part of the main body 10d on the upper side of the operation port 41d is made of existing transparent materials to form an observation window 111d, and the size of the observation window 111d in the length direction of the main body 10d is adapted to the size of the operation port 41d in the length direction of the main body 10d to ensure that the part of the indwelling head can be observed through the observation window 111d no matter where it is located in the operation port 41d. Correspondingly, at least part of the first fixing portion 20d is also made of transparent material to correspond to the observation window 111d.

[0079] In this embodiment, the first fixing portion 20d is entirely made of transparent material.

[0080] The utility model also constructs a vascular access system for establishing a temporary vascular access for a patient. The vascular access system includes a vascular indwelling access and any one of the vascular access fixing devices in any of the above embodiments. The vascular access fixing device 1 in the first embodiment is now taken as an example to describe the vascular access system in detail.

[0081] The vascular indwelling passage includes an infusion clamp, an infusion connector, a catheter and an indwelling head, wherein the two ends of the catheter are respectively connected to the infusion connector and the indwelling head, the indwelling head is used to puncture the patient's skin, the infusion connector is used to connect to the infusion tube, and the infusion clamp is used to adjust the flow rate. The indwelling head is inserted into the operating part 40, and the infusion clamp and / or the infusion connector box / or the catheter is accommodated between at least one fixed part and the second surface 102.

[0082] Specifically, the infusion clamp and part of the catheter are fixed between the second fixing portion 30 and the second surface 102, and the infusion connector and part of the catheter are fixed between the first fixing portion 20 and the second surface 102. It can be understood that the above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the utility model.
