Description

Technical Field

[0001] This utility model relates to the field of human life necessities, and in particular to medical auxiliary equipment, especially an anticoagulation tube placement auxiliary bending connection device. Background Technology

[0002] Clinically, for patients with portal vein embolism after liver transplantation, an anticoagulant catheter is implanted in the abdomen, and anticoagulant heparinized saline is administered. The anticoagulant catheter is connected to an extension tube via a connector, and the heparinized saline container is connected to the extension tube. The saline solution is pumped into the patient's body sequentially through the extension tube, connector, and anticoagulant catheter to achieve anticoagulation therapy. The connector is then secured to the patient's abdomen with tape. However, this method has the following drawbacks:

[0003] 1. Anticoagulation catheters are usually thin, rigid tubes with high elasticity. After the anticoagulation catheter is connected to the connector by a plug-in method, the connector and extension tube sag due to gravity, forcing the anticoagulation catheter to bend. The elastic force generated by the bending of the anticoagulation catheter can easily cause the anticoagulation catheter to fall out of the connector, affecting the treatment.

[0004] 2. The joint is fixed to the patient's abdomen with tape for a long time, which can easily cause pressure sores due to skin compression, and the tape is not firmly attached. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary bending connection device for anticoagulant tube placement, which aims to solve the technical problems in the prior art where the elastic force generated by bending the anticoagulant tube easily causes the anticoagulant tube to come out of the joint, and the joint easily compresses the skin, causing pressure sores.

[0006] An anticoagulant insertion tube auxiliary bending connection device includes an adhesive sheet with adhesive on its back and a turntable on its front, the turntable being rotatably connected to the adhesive sheet. A connector is provided on the turntable, one end of which has an auxiliary bending sleeve, and the other end has an extension tube. The outer diameter of the auxiliary bending sleeve and the extension tube are the same, and the auxiliary bending sleeve, connector, and extension tube are sequentially connected. One or more transverse latches and one or more longitudinal latches are provided around the center of the adhesive sheet at the edge of its front side. Both the transverse and longitudinal latches can be matched and engaged with the outer diameter of the auxiliary bending sleeve or the extension tube. The device also includes an anticoagulant insertion tube, one end of which is connected to the human body, and the other end of which passes through the auxiliary bending sleeve and is then inserted into one end of the connector.

[0007] Furthermore, the top edge of the front side of the adhesive patch is provided with an upward marking.

[0008] Furthermore, there are two vertical clips, which are respectively located on the left and right sides of the adhesive sheet; there are two horizontal clips, which are respectively located at the upper left and upper right corners of the adhesive sheet.

[0009] The working principle of this utility model:

[0010] The adhesive patch is applied to the patient's abdomen. The open end of the anticoagulant catheter is inserted into the tube of the auxiliary bending sleeve and connected to the corresponding end of the connector. The auxiliary bending sleeve is then engaged in the longitudinal and / or transverse clips on one side according to the required bending angle. At this time, the engagement point of the auxiliary bending sleeve is compressed and contracted, thereby bringing the inner wall of the auxiliary bending sleeve into contact with the outer wall of the anticoagulant catheter. The friction between the auxiliary bending sleeve and the anticoagulant catheter is used to fix the anticoagulant catheter, preventing it from coming out of the connector.

[0011] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0012] 1. The anti-condensation tube and connector of this utility model are connected by an auxiliary bending sleeve that is fitted over the anti-condensation tube. The friction between the inner wall of the auxiliary bending sleeve and the outer wall of the anti-condensation tube prevents the anti-condensation tube from coming out of the connector.

[0013] 2. The auxiliary bending sleeve of this utility model can be snapped onto the horizontal and / or vertical buckles according to the bending angle requirements, thereby fixing the bending arc and preventing the anti-condensation tube from straightening back due to elasticity.

[0014] 3. The adhesive patch of this utility model avoids direct contact between the connector and the patient's skin, increases the contact area, and avoids pressure sores. Attached Figure Description

[0022] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0023] like Figures 1 to 6 As shown, this embodiment provides an anticoagulant catheter insertion auxiliary bending connection device, including a circular adhesive patch 1. The adhesive patch 1 is made of medical plastic sheet, and the back of the adhesive patch 1 is covered with adhesive. The adhesive patch 1 can be attached to the patient's body by means of adhesive, avoiding direct contact between the connector 3 and the patient's skin, increasing the contact area, dispersing pressure, and avoiding pressure sores.

[0024] The front of the adhesive sheet 1 is provided with a turntable 2, which is rotatably connected to the adhesive sheet 1. A connector 3 is snapped onto the turntable 2. The outer ring of one end of the connector 3 is heat-fused to one end of the auxiliary bending sleeve 4. The other end of the auxiliary bending sleeve 4 is open. The other end of the connector 3 is inserted into one end of the extension tube 5. The outer diameters of the auxiliary bending sleeve 4 and the extension tube 5 are the same. The auxiliary bending sleeve 4, the connector 3, and the extension tube 5 are connected in sequence.

[0025] The end of the extension tube 5 is plugged with a cap, which is then opened and connected to the heparinized saline delivery system.

[0026] This embodiment is used in conjunction with an anticoagulant catheter 10 implanted in the patient's abdomen. The anticoagulant catheter 10 is a thin, rigid tube. One end of the anticoagulant catheter 10 is connected to the human body, and the other end of the anticoagulant catheter 10 is inserted into the tube of the auxiliary bending sleeve 4 and then inserted into the inner ring of one end of the connector 3. This allows the auxiliary bending sleeve 4 to be fitted over the anticoagulant catheter 10. The friction between the inner wall of the auxiliary bending sleeve 4 and the outer wall of the anticoagulant catheter 10 prevents the anticoagulant catheter 10 from coming out of the connector 3, and also protects the anticoagulant catheter 10 from breakage during connection. Heparinized saline is connected to the open section of the extension tube 5 and is pumped into the patient's body sequentially through the extension tube 5, connector 3, and anticoagulant catheter 10 to achieve anticoagulation therapy.

[0027] On the edge of the front of the adhesive sheet 1, one or more horizontal snaps 7 and one or more vertical snaps 6 are arranged around the center of the adhesive sheet 1; both the horizontal snaps 7 and the vertical snaps 6 can be matched and snapped with the outer diameter of the auxiliary bending sleeve 4 or the extension tube 5; in this embodiment, there are two vertical snaps 6, which are respectively arranged on the left and right sides of the adhesive sheet 1; there are two horizontal snaps 7, which are respectively arranged at the upper left corner and the upper right corner of the adhesive sheet 1; the vertical snaps 6 on the left side and the horizontal snaps 7 at the upper left corner form one group, and the vertical snaps 6 on the right side and the vertical snaps 6 at the upper right corner form another group. When the auxiliary bending sleeve 4 is snapped with the snaps, one group can be selected to snap the auxiliary bending sleeve 4 onto one side of the adhesive sheet 1, thereby fixing the curvature of the auxiliary bending sleeve 4 and preventing the anti-condensation tube 10 inside the auxiliary bending sleeve 4 from coming out of the joint 3 due to elastic straightening.

[0028] In the storage state, rotating the turntable 2 causes the connector 3 to be placed horizontally. The auxiliary bending sleeve 4 sequentially engages with the longitudinal buckles 6 and transverse buckles 7 on the left side, and the extension tube 5 sequentially engages with the longitudinal buckles 6 and transverse buckles 7 on the right side. This fixes both the auxiliary bending sleeve 4 and the extension tube 5 to the front of the adhesive sheet 1, reducing storage space while securing the auxiliary bending sleeve 4 and the extension tube 5. The package includes a packaging bag 9, which is sterilized at the factory and placed in a packaging bag in a storage state for easy transportation and safe storage. When using, the packaging bag 9 is torn open to remove the package.

[0029] The top edge of the front of the adhesive patch 1 is marked with an upward indicator 8 to indicate the direction of adhesion.

[0030] How to use this embodiment:

[0031] When using, tear open the packaging bag 9 and take out the embodiment. At this time, the embodiment is in the storage state. The auxiliary bending sleeve 4 is sequentially connected to the longitudinal buckle 6 and the transverse buckle 7 of the left group. The extension tube 5 is sequentially connected to the longitudinal buckle 6 and the transverse buckle 7 of the right group. Remove the auxiliary bending sleeve 4 and the extension tube 5 from the buckles respectively, and rotate the turntable 2 to make the connector 3 vertical. Then, peel off the protective film on the adhesive back of the adhesive patch 1 and stick it to the patient's abdomen. Insert the open end of the anticoagulant catheter 10 into the tube of the auxiliary bending sleeve 4 and connect it to the corresponding end of the connector 3. Lock the auxiliary bending sleeve 4 into the longitudinal buckle 6 and / or transverse buckle 7 on one side according to the required bending angle. At this time, the locking point of the auxiliary bending sleeve 4 is compressed and contracted, making the inner wall of the auxiliary bending sleeve 4 in close contact with the outer wall of the anticoagulant catheter 10. The friction between the auxiliary bending sleeve 4 and the anticoagulant catheter 10 secures the anticoagulant catheter 10, preventing it from dislodging from the connector 3. The extension tube 5 hangs naturally. After opening the cap, the open end of the extension tube 5 connects to the external heparin saline delivery system. The heparin saline delivery system includes, but is not limited to, an infusion pump and an infusion needle, thereby pumping heparin saline into the patient's body sequentially through the extension tube 5, connector 3, and anticoagulant catheter 10 to achieve anticoagulation therapy.
