Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular, to a CVC fixing and anti-extubation device. Background Art

[0002] CVC refers to a percutaneous central venous catheter. In clinical treatment, CVC catheters are often used to infuse drugs and nutrients into patients. CVC must be properly fixed after placement. Once the catheter is accidentally pulled out or slipped, it will aggravate the patient's condition, increase the patient's hospitalization time and medical expenses. If it is not discovered in time or handled improperly, it may even affect the patient's life safety.

[0003] There are a lot of literatures discussing and analyzing the reasons for unplanned CVC extubation in patients, and taking corresponding preventive measures, such as using 3M fixing tape for secondary fixation, using SILOX catheter fixation stickers, strengthening observation of high-risk patients, strengthening health education for patients and their families, standardizing the operation of medical staff, etc. However, it is found in clinical work that the incidence of unplanned extubation is still very high;

[0004] In order to effectively reduce the risk of unplanned CVC extubation and avoid unplanned extubation, it is necessary to design a CVC fixed anti-extubation device. Utility Model Content

[0007] a second clamping block, forming a second groove corresponding to the first groove;

[0008] A base, used for supporting the first clamping block;

[0009] A flip cover, used to support the second clamping block, and one side of which is flippably disposed on the base;

[0010] The flip cover drives the second clamping block to flip together so that the second clamping block fits with the first clamping block to form a clamping state for fixing the CVC tube;

[0011] In the clamped state, the surfaces of the first groove and the second groove are at least partially in contact with the surface of the CVC tube;

[0012] When in use, it is only necessary to place the CVC tube in the first groove; the flip cover drives the second clamping block to flip together so that the second clamping block fits with the first clamping block; the CVC tube is fixed to the base through the interaction force between the first clamping block and the second clamping block; at the same time, the base can be fixed to the patient through a strap to prevent the CVC from being accidentally pulled out during the patient's daily movements.

[0013] Furthermore, the surfaces opposite to each other of the base and the flip cover are formed with sliding grooves corresponding to the first clamping block and the second clamping block;

[0014] The slide groove guides the first clamping block and the second clamping block to reciprocate along the radial direction of the CVC tube;

[0015] The first clamping block and the second clamping block are both connected to the bottom of the slide groove through an elastic member.

[0016] Furthermore, the elastic member is a spring, which always applies an elastic force to the first clamping block and the second clamping block to move closer to each other in the clamping state.

[0017] Further, a hinge hole is formed on the surface of the base;

[0018] The side wall of the flip cover forms a hinge rod corresponding to the hinge hole;

[0019] The hinge rod and the hinge hole are connected by a torsion spring, and a torsion force is always applied to keep the flip cover in an open state;

[0020] Wherein, a limiting structure is arranged on the base and the flip cover to prevent the flip cover from returning to its original position in the clamped state.

[0021] Furthermore, the limiting structure includes:

[0022] A limiting block is provided on the flip cover and is provided corresponding to the limiting groove formed on the surface of the base;

[0023] A buckle is arranged on the limiting block and is arranged corresponding to the clamping groove formed on the inner wall of the limiting groove;

[0024] An unlocking block is movably disposed on the inner wall of the card slot and partially protrudes from the side wall of the base;

[0025] The buckle and the limit block are connected by springs.

[0026] Furthermore, the card slot is located on the side wall of the limiting slot and penetrates the base in a direction away from the sliding slot;

[0027] After the limiting block is inserted into the limiting groove, the buckle is driven to be embedded in the groove under the action of the spring sheet to form a locked state of the flip cover.

[0028] Furthermore, the inner wall of the card slot is formed with a moving slot for guiding the unlocking block to slide along the extending direction of the card slot;

[0029] The unlocking block is partially embedded in the moving groove so that the unlocking block can only move along the moving groove;

[0030] The extension distance of the moving slot is always smaller than the extension distance of the card slot.

[0031] Furthermore, the side edge of the buckle forms an arc surface that interferes with the notch of the limiting groove.

[0032] Furthermore, the side walls of the base and the flip cover are both formed with arc grooves corresponding to the CVC tube.

[0033] Furthermore, straps are provided on both sides of the base.

[0061] A first groove a1 is formed on the surface of the first clamping block 1, and the first groove a1 is configured as an arc shape corresponding to the CVC; in this embodiment, two first grooves a1 are provided; wherein the number of the first grooves a1 can be set according to actual conditions; a second clamping block 2 is provided at a position opposite to the first clamping block 1, and a second groove a2 corresponding to the first groove a1 is formed on the surface of the second clamping block 2;

[0062] Specifically, the CVC fixed anti-extubation device also includes a base 3 for supporting the first clamping block 1 and a flip cover 4 for supporting the second clamping block 2; wherein any one side of the flip cover 4 is flipped and arranged on the base 3; the side walls of the base 3 and the flip cover 4 are both formed with a circular arc groove a3 corresponding to the CVC tube 100; wherein the surface of the first groove a1 and the surface of the second groove a2 are not lower than the surface of the circular arc groove a3;

[0063] Through the design of the above solution, as long as the rotating cover 4 drives the second clamping block 2 to flip in the direction close to the first clamping block 1, and the second clamping block 2 is fitted with the first clamping block 1, a clamping state for fixing the CVC tube 100 is formed; wherein, in the clamping state, the surfaces of the first groove a1 and the second groove a2 are at least partially in contact with the surface of the CVC tube 100; thus, the CVC tube 100 is fixed;

[0064] Among them, two straps 5 are fixed on both sides of the base 3, and the device can be fixed on the patient through the setting of the straps 5; it can be understood that the two straps 5 are passed around the patient's neck and fixed in the form of Velcro or buckles, so that the CVC tube 100 can be directly fixed on the patient through the device to prevent extubation due to the patient's daily movements.

[0065] In some embodiments, the surface portion located at the base 3 is concave to form a slide groove a31 corresponding to the first clamping block 1; the surface portion located at the flip cover 4 opposite to the base 3 is also concave to form a slide groove a31 corresponding to the second clamping block 2; the slide groove a31 guides the first clamping block 1 and the second clamping block 2 to reciprocate along the radial direction of the CVC tube 100; specifically, the first clamping block 1 and the second clamping block 2 are both connected to the bottom of the slide groove a31 through an elastic member 6; wherein the elastic member 6 is a spring, which always gives an elastic force to the first clamping block 1 and the second clamping block 2 to approach each other in the clamping state;

[0066] Through the above scheme, in the clamping state, the CVC tube 100 is wrapped by the first groove a1 and the second groove a2; under the elastic force of the elastic member 6, the first clamping block 1 and the second clamping block 2 are squeezed against each other, giving the CVC tube 100 a certain squeezing force, so that it is fixed more stably.

[0067] In some embodiments, a hinge hole a9 is formed on the surface of the base 3, and a hinge rod 91 corresponding to the hinge hole a9 is formed on the side wall of the flip cover 4; the hinge rod 91 is connected to the hinge hole through a torsion spring 9, and always applies a torque to the flip cover 4 in an open state; wherein, a limiting structure is provided on the base 3 and the flip cover 4 to prevent the flip cover 4 from resetting in a clamped state;

[0068] Specifically, the limiting structure includes: a limiting block 71, a buckle 72, and an unlocking block 73;

[0069] The relative surfaces of the base 3 and the flip cover 4 are partially concave to form a limiting groove a7, and the surface of the flip cover 4 is partially convex to form a limiting block 71 arranged corresponding to the limiting groove a7; after the flip cover 4 is turned over, the limiting block 71 can be inserted into the limiting groove a7; the inner wall portion located in the limiting groove a7 penetrates the base 3 in the direction away from the slide groove a31 to form a clamping groove a71, and the surface of the limiting block 71 is moved to the buckle 72 corresponding to the clamping groove a71; wherein the buckle 72 is connected to the limiting block 71 by a spring sheet 74, and the spring sheet 74 always gives the buckle 72 an elastic force away from the limiting block 71; preferably, the side of the buckle 72 forms a circular arc surface a72 that conflicts with the notch of the limiting groove a7; when the circular arc surface a72 of the buckle 72 conflicts with the notch of the limiting groove a7, the buckle 72 can be driven to retract into the limiting block 71;

[0070] When the locking cam 71 is in the unlocking state, the locking cam 72 is in the unlocking state, and the locking cam 72 is locked in the unlocking state.

[0071] More specifically, an unlocking block 73 that contacts the buckle 72 is movable on the inner wall of the slot a71, and the unlocking block 73 partially protrudes from the side wall of the base 3; wherein, the inner wall of the slot a71 forms a sliding groove for guiding the unlocking block 73 to slide toward / away from the buckle 72 along the extension direction of the slot a71; specifically, the extension distance of the moving groove is always smaller than the extension distance of the slot a71; the end surface of the unlocking block 73 located in the slot a71 is at least flush with the inner wall of the limiting slot a7; when unlocking is required, just press the unlocking block 73 so that the unlocking block 73 contacts the buckle 72 and pushes the buckle 72 away from the slot a71; then, under the action of the torsion spring 9, the flip cover 4 is opened.
