Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a deep vein double-lumen catheter fixing device. Background Art
[0002] Deep venous catheterization refers to a treatment method in which a catheter is inserted into the deep large veins and central veins through a relatively superficial vein. After the retention tube of the deep venous double-lumen catheter is placed in the patient's body, in order to avoid the risk of the tube falling out, the part remaining outside usually needs to be fixed to the patient's body. Traditional deep venous double-lumen catheter fixation is to pass sutures through the catheter butterfly buckle and sew them to the patient's skin for fixation, which will increase the patient's pain. There is also a risk of infection, and loose sutures may also lead to the risk of tube falling out.
[0003] To this end, we designed a deep vein double-lumen catheter fixation device. Utility Model Content
[0004] The purpose of the present invention is to provide a deep vein double-lumen catheter fixing device to address the deficiencies of the prior art and to solve the problems raised in the background art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deep vein double-lumen catheter fixing device, comprising a catheter butterfly buckle and a fixing patch, wherein a pair of sub-buckles are symmetrically fixedly installed on the back of both side plates of the catheter butterfly buckle, and a pair of female buckles are symmetrically fixedly installed on the front of the fixing patch, and the positional relationship between the two sub-buckles is the same as the positional relationship between the two female buckles, and the sub-buckles and the female buckles can be buckled with each other.
[0006] Preferably, a first catheter is inserted into the through hole above the catheter butterfly buckle, one end of the first catheter is connected to the bottom outlet of the tee, the two top inlets of the tee are connected to the second catheter, and the two second catheters are provided with catheter clamps.
[0007] Preferably, the fixing patch is a medical non-woven fabric fixing patch.
[0008] Preferably, the sub-button and the main button are circular magnetic buttons.
[0009] Preferably, the catheter clamp is a Robert clamp, and the two catheter clamps are of different colors.
[0010] Compared with the existing technology, the present invention provides a deep vein double-lumen catheter fixing device with the following beneficial effects:
[0011] The deep vein double-lumen catheter fixing device is provided with a fixing patch and a snap buckle between the fixing patch and the catheter butterfly buckle on the three-way piece. The fixing patch is adhered to the patient's skin, and then the snap buckles are fastened together to fix the outer part of the deep vein double-lumen catheter to the patient's body, thereby avoiding the risk of the tube coming off. The operation process is simple and convenient, and no stitches or sutures need to be sutured or removed when fixing or replacing the deep vein double-lumen catheter, which can alleviate the patient's pain and eliminate the risk of infection.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] See also Figure 1-Figure 3 , see Figure 1-Figure 3A catheter butterfly buckle 3 is fixedly installed on the tee piece 1, and a pair of sub-buckles 4 are fixedly installed on the back of the two side plates of the catheter butterfly buckle 3. The fixing patch 2 adopts a medical non-woven fabric fixing patch. The non-woven fabric fixing patch is moisture-proof, breathable and non-irritating. A pair of female buckles 5 are fixedly installed on the front of the fixing patch 2. The positional relationship of the two sub-buckles 4 is the same as that of the two female buckles 5. The sub-buckles 4 and the female buckles 5 can be buckled with each other. When fixing the deep vein double-lumen catheter, tear off the release film on the back of the fixing patch 2, and stick the adhesive back to the patient's skin. By buckling the sub-buckle 4 onto the female buckle 5, the tee piece 1 can be fixed to the fixing patch 2. On, the deep vein double-lumen catheter is fixed to the patient's skin. Compared with fixing the deep vein double-lumen catheter with sutures, this operation is simpler and will not cause pain to the patient. The sub-buckle 4 and the mother buckle 5 adopt circular magnetic buckles. The sub-buckle 4 will attract and buckle with each other when it is close to the mother buckle 5. Medical staff do not need to press with their fingers to buckle the sub-buckles with each other, so it will not cause discomfort to the patient. Moreover, the sub-buckles are not easy to loosen after being buckled, which can effectively avoid the risk of tube detachment. When the deep vein double-lumen catheter needs to be removed, the sub-buckle 4 can be separated from the mother buckle 5. Compared with removing sutures, the operation is simpler and the patient will not feel pain.
[0018] See also Figure 1 The bottom outlet of the tee 1 is connected to the first conduit 6, and the two top inlets of the tee 1 are connected to the second conduit 7. The two second conduits 7 are both provided with a conduit clamp 8. The conduit clamp 8 is a Robert clamp. The two conduit clamps 8 have different colors. The function of the conduit clamp 8 is to stop the flow in the second conduit 7. By setting the two conduit clamps 8 to two different colors, medical staff can help distinguish the two second conduits 7.
[0019] The working principle and usage process of the present invention are as follows: when using the deep vein double-lumen catheter fixing device, after placing the retention tube of the deep vein double-lumen catheter into the patient's body, select a position on the patient's skin close to the catheter butterfly buckle 3, tear off the release film on the back of the fixing patch 2, and then stick the fixing patch 2 to the skin position just selected, and finally move the sub-buckle 4 on the catheter butterfly buckle 3 close to the female buckle 5 on the fixing patch 2 so that the sub-buckle 4 and the female buckle are sucked together, and the deep vein double-lumen catheter is fixed. When the deep vein double-lumen catheter needs to be removed, the sub-buckle 4 can be separated from the female buckle 5, and the fixing patch 2 can be left on the patient's skin and can still be used to fix the deep vein double-lumen catheter.
[0020] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
