Description

Technical Field

[0001] The utility model relates to the technical field of leg puncture tube fixation, in particular to a leg puncture tube fixation device. Background Art

[0002] Intra-aortic balloon pumping (IABP) involves inflating the balloon during diastole, increasing aortic diastolic pressure and coronary artery pressure, which increases myocardial blood and oxygen supply. Before cardiac contraction, the balloon deflates, decreasing aortic pressure, cardiac afterload, cardiac ejection resistance, and myocardial oxygen consumption. [1] Coronary heart disease is a common and frequent cardiovascular disease. The main pathological changes are varying degrees of coronary artery stenosis, myocardial ischemia, and an imbalance between myocardial oxygen supply and demand. IABP can effectively increase myocardial blood supply and reduce oxygen consumption, benefiting patients with coronary heart disease the most.

[0003] When using the IABP pump, the patient's knees need to be kept straight, and the patient usually relies on himself to keep his legs straight. However, during the treatment process, it is difficult for the patient to actively keep his legs straight for a long time, which affects the use of the IABP pump. At the same time, there are multiple sets of tubes in the thigh, and the tubes are usually fixed to the patient's skin with tape. However, in the process of fixing the tubes, the tubes are messy when fixed with tape, and the tubes cross each other, affecting the medical staff's real-time observation of the situation in each tube. At the same time, the messy tubes make it difficult for medical staff to quickly distinguish between the tubes.

[0004] The utility model with patent number CN212730674U discloses a multi-purpose medical tube fixing device, including a tube fixing component and a limb fixing component. The tube fixing component is located above the limb fixing component and is used to fix medical tubes; the limb fixing component is located on the human limbs and is used to fix the multi-purpose medical tube fixing device to the human limbs or head and neck; the tube fixing component includes a fixing chassis, a tube fixing seat and a size adjustment device; the fixing chassis is a flat structure and is fixed to the limb fixing component; the tube fixing seat is fixed above the fixing chassis, and a medical tube fixing groove is provided in the middle of the tube fixing seat for passing medical tubes; the size adjustment device is located on the tube fixing seat and is used to adjust and fix medical tubes of different specifications; the medical tube passes through the medical tube fixing groove, and then the adjusting bolt is rotated to move the position of the fixing block connected to the adjusting screw through the adjusting screw, thereby firmly fixing the medical tube located in the medical tube fixing groove, and then the entire device is fixed to the patient's limbs or head and neck through a fixing belt. In this patent, the medical management is clamped in the fixed groove by adjusting the screw, but during use, after the fixing belt is connected and fixed to the patient's limbs, the position of the fixed groove is fixed accordingly, so that the position of the medical tube clamped in the fixed groove is fixed accordingly. In the case where there are multiple sets of medical management on the patient, the tubes intersect with each other and have different connection positions with the patient. In the above patent, since the position of the fixed groove on the patient's limb is fixed, it is difficult to adjust the position of the fixed groove according to the position and direction of each tube to adapt to the fixation needs of different management.

The elastic bag expands during inflation, so that the inner lining 8 on the fixing sleeve 1 is in close contact with the patient's skin. At this time, the radial direction of the elastic bag is the same as the direction of movement of the patient's leg. Since the elastic bag expands and is connected to the patient's leg through the restraint belt 2, the fixing sleeve 1 is supported by the elastic bag. Since the fixing sleeve 1 is rolled into a circle and restrained on the outside of the patient's leg, the patient's leg cannot bend, and the patient's leg is kept in a straight state.

[0027] For further information, see Figure 3 The fixing plate 4 includes a flexible adjustment rib 401, a silicone sleeve 402 arranged outside the flexible adjustment rib 401, and a connecting piece 403 arranged at the bottom end of the silicone sleeve 402; the fixing piece 5 is fixedly installed on the silicone sleeve 402; the connecting piece 403 is detachably connected to the fixing sleeve 1.

[0033] Preferably, the elastic sheet 501 is made of metal, and the two groups of elastic sheets 501 are fixed on the silicone sleeve 402 in a “V” shape.

[0034] In the above arrangement, after changing the position of the fixing member 5 by bending the flexible adjustment rib 401, when fixing the pipeline, it is fixed in the limiting channel 6 between the two sets of elastic sheets 501, and the pipeline is clamped by the elastic sheets 501, thereby fixing different pipelines.

[0035] In this embodiment, the fixing sleeve 1 is supported by the inflated elastic bag, and the restraint belt 2 is used to connect the fixing sleeve 1 to the patient's knee (knee), thereby restricting the patient's legs and keeping the patient's legs in a straight state; according to the position of the pipeline connected to the patient, the fixing plate 4 is separated from the fixing sleeve 1, the position of the fixing plate 4 on the fixing sleeve 1 is adjusted, and the flexible adjustment rib 401 can be bent, so that the position of the fixing part 5 on the same group of fixing plates 4 is changed, so that different pipelines can be fixed.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
