Description

Technical Field

[0001] The utility model relates to the technical field of infusion needle fixers, in particular to a bone marrow cavity puncture infusion needle fixer. Background Art

[0002] Bone marrow intracavitary infusion is a basic requirement for the treatment of critically ill patients. In the past, it was mainly achieved through intravenous access, based on the method and principle of establishing veins in "8 parts and 16 points throughout the body" so that different patients can be selected under different circumstances. However, even the most convenient and quickest points require professional medical staff to complete, and may be limited by certain conditions and difficult to meet the "Platinum Ten Minutes" requirement.

[0003] Commonly used puncture sites The puncture sites reported in the literature are the tibia, ilium, sternum, etc., and some people choose the humerus, femur, clavicle and tibial medial malleolus according to personal experience. The upper end of the tibia is often used in adults, and the most commonly used puncture point is about 3 cm below the tibial plateau. Warren et al.'s research shows that the distal tibia, distal femur, and proximal humerus can also be used as infusion sites, and their efficacy is similar to that of veins; the ilium, sternum, and clavicle, which are rich in red bone marrow, can also be used, but they are not as convenient as the long bones of the limbs and have a high success rate. In short, as long as the bone marrow cavity can be entered, many parts can establish a bone marrow cavity access.

[0004] With the clinical application of bone marrow puncture and infusion technology in critically ill patients, it was found that the bone puncture needle was not well fixed during bone marrow puncture and infusion at the tibia. Now, thickened cotton pads combined with multi-layer spinning stacks are used for fixation. In the absence of favorable support from hard materials, the bone puncture needle position is easily shifted, resulting in fluid extravasation and compartment syndrome or osteomyelitis. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a bone marrow puncture infusion needle holder comprises a first fixing component and a second fixing component, wherein a first groove is arranged on the inner side wall of the first fixing component;

[0006] A second groove is provided on the inner side wall of the second fixing component, and the first groove on the first fixing component and the second groove on the second fixing component constitute an infusion needle accommodating cavity;

[0007] A fixing strap 1 is disposed on the outer sides of the first fixing component and the second fixing component.

[0008] Furthermore, a second fixing strap is provided at the bottom ends of the first fixing component and the second fixing component.

[0009] Furthermore, a plurality of first fixing grooves are arranged on the outer side of the first fixing component, and a plurality of second fixing grooves are arranged on the outer side of the second fixing component, so as to fix the placement of the first binding belt.

[0010] Furthermore, the first fixing component and the second fixing component are both made of silicone material.

[0011] The advantages of the utility model compared with the prior art are:

[0012] The utility model properly fixes the bone marrow puncture infusion needle by means of the first fixing component and the second fixing component, and fixes it by means of the fixing strap one, and fixes it on the tibia skin by means of the fixing strap two, thereby ensuring that the bone marrow puncture indwelling needle does not shift or fall off, thereby achieving the purpose of safe infusion, and further facilitating the smooth rescue process of critically ill patients.
