[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1, reference Figure 1 and Figure 2, which is the first embodiment of the present invention, and this embodiment provides an infusion fixing structure for intensive care. The infusion fixing structure for intensive care includes a main body component 100, including a wrist strap 101, a connecting frame 102, a hand strap 103, an upper splint 104, a lower splint 105 and a connecting block 106. The hand strap 103 and the wrist strap 101 are fixed by Velcro straps of their own straps, the connecting frame 102 is a rigid support frame, the connecting block 106 is fixed to the top of the connecting frame 102, and the upper splint 104 and the lower splint 105 are fixed by bandages.

[0036] The connecting frame 102 is fixed by the wrist strap 101 and the hand strap 103. The upper splint 104 and the lower splint 105 clamp the hand and wrist to prevent the patient's hand and wrist from shaking randomly, thereby reducing the patient's hand movement. The upper splint 104 and the lower splint 105 do not affect the patient's finger movement, so that the patient's fingers can move, thereby preventing the fingers from being stiff due to long-term immobility.

[0037] When in use, first fix the wrist strap 101 and the hand strap 103 to the patient's hand and wrist, so as to position the connecting frame 102. At this time, the infusion needle can be inserted into the blood vessel on the back of the patient's hand, and hemostatic cotton is applied to the insertion site. At this time, the upper splint 104 and the lower splint 105 are fixed by bandages, and the connecting block 106 is snapped into the upper splint 104, so as to fix the position of the upper splint 104, so that the relative position of the upper splint 104 and the infusion needle is fixed.

[0038] The protection assembly 200 is arranged on the upper clamping plate 104, and includes a support block 201a fixed to the top of the upper clamping plate 104, a threaded rod 201b is fixed to one side of the support block 201a, a threaded sleeve 201c is connected to the surface of the threaded rod 201b by a threaded rotation, a bracket 201d is slidably connected to the surface of the threaded rod 201b, the bracket 201d and the threaded rod 201b are connected by a torsion spring, a sliding rod 201e slides inside the bracket 201d, a first spring 201f is fixed to the end of the sliding rod 201e, and a sliding column 201e slides inside the sliding rod 201e 1g, a slot 201d-1 is provided in the bracket 201d, the sliding column 201g is inserted into the slot 201d-1, a driving column 201h is fixed to the end of the sliding column 201g, a moving plate 201i is slidable in the bracket 201d, a slot 201i-1 is provided on one side of the moving plate 201i, the driving column 201h can be inserted into the slot 201i-1, a reset rod 201j is slidable in the moving plate 201i, a second spring 201k is fixed to one side of the driving column 201h, and the other end of the second spring 201k is fixed to the inner wall of the sliding rod 201e.

[0039] The bracket 201d and the threaded rod 201b are connected by a torsion spring, so that the bracket 201d can be pressed toward the upper clamping plate 104 under the action of the restoring elastic force of the torsion spring. By rotating the threaded sleeve 201c, the position of the threaded sleeve 201c on the threaded rod 201b can be adjusted, thereby adjusting the position of the bracket 201d, so as to facilitate the movable plate 201i to support the infusion needle. The infusion needle is fixed in the movable plate 201i. When the infusion needle is pulled by the infusion tube, the movable plate 201i can be driven to move synchronously. The first spring 201f is in a stretched state, which is used to pull the sliding rod 201e, and the second spring 201k is in a compressed state, which is used to push the driving column 201h into the slot 201i-1.

[0040] Specifically, the protection component 200 also includes a protection member 202, which is arranged in the movable plate 201i, including a third spring 202a fixed to the inner wall of the movable plate 201i, the other end of the third spring 202a is fixed to the inner wall of the bracket 201d, an insertion rod 202b is sliding in the movable plate 201i, a limiting groove 201d-2 is provided in the bracket 201d, the end of the insertion rod 202b is inserted into the limiting groove 201d-2, an inclined surface 202b-1 is provided at the end of the insertion rod 202b, and a fourth spring 202c is fixed between the two insertion rods 202b.

[0041] The third spring 202a is in a stretched state, and is used to pull the movable plate 201i, so that the movable plate 201i will not slide easily in the bracket 201d. The fourth spring 202c is in a compressed state, and is used to push the insertion rod 202b. By inserting the insertion rod 202b into the limiting groove 201d-2, the movable plate 201i will not move in the opposite direction after sliding.

[0042] When the infusion needle fixed in the movable plate 201i is pulled by the infusion tube, the movable plate 201i can be driven to move synchronously, so that the movable plate 201i slides in the bracket 201d. At this time, the inclined surface 202b-1 of the insertion rod 202b slides from one side of the limiting groove 201d-2. When the infusion needle stops moving, the insertion rod 202b is inserted into the limiting groove 201d-2, so that the movable plate 201i will not move in the opposite direction after sliding, thereby preventing the infusion needle from moving back and injuring the blood vessel, thereby further protecting the safety of the patient.

[0043] Specifically, the protective component 200 also includes a clamping member 203, which is arranged in the movable plate 201i, including a support plate 203a sliding in the movable plate 201i, a clamping block 203b sliding on the surface of the support plate 203a, a limiting block 203c fixed in the clamping block 203b, a fifth spring 203d is arranged between the two clamping blocks 203b, and a positioning block 203e is fixed on the top of the support plate 203a.

[0044] The support plate 203a is used to support the clamping block 203b, and the positioning block 203e is used to support the two clamping blocks 203b. Two limit blocks 203c are fixed in each clamping block 203b. The fifth spring 203d is in a stretched state and is used to pull the two clamping blocks 203b closer to each other. Through the cooperation of the clamping block 203b and the limit block 203c, the base of the infusion needle can be clamped and fixed, and through the cooperation of the movable plate 201i, the bracket 201d, the upper splint 104 and the lower splint 105, the infusion needle is fixed to the patient's hand, effectively preventing the needle from falling off due to hand movements such as unconscious grasping, swinging, etc., thereby avoiding bleeding, pain and the trouble of re-puncture that may be caused by the needle falling off.

[0045] Specifically, the clamping member 203 also includes a driving handle 203f fixed to one side of the clamping block 203b, a positioning rod 203g is fixed to one side of the clamping block 203b, the positioning rod 203g slides in the support plate 203a, a clamping block 203h is fixed at the end of the positioning rod 203g, a fixed groove 201i-2 is opened in the movable plate 201i, and the clamping block 203h can be inserted into the fixed groove 201i-2.

[0046] By moving the driving handle 203f, the two clamping blocks 203b can be moved away from each other. When the clamping block 203b moves away from the positioning block 203e, the positioning rod 203g can be driven to move, so that the positioning rod 203g drives the clamping block 203h to move out of the fixed groove 201i-2, thereby releasing the limit on the support plate 203a, so that the position of the support plate 203a in the movable plate 201i can be adjusted, and the clamping block 203b is moved to one side of the infusion needle base, thereby facilitating the clamping and positioning of the infusion needle base.

[0047] Specifically, the protective component 200 also includes a support member 204, which is arranged on one side of the bracket 201d, including a support seat 204a fixed to the end of the bracket 201d, a first support rod 204b is rotatably connected inside the bracket 201d, a second support rod 204c is hinged at the other end of the first support rod 204b, one side of the second support rod 204c is rotatably connected to a support wheel 204d, the other end of the second support rod 204c is rotatably connected to a drive rod 204e, and the drive rod 204e is fixed to one side of the movable plate 201i.

[0048] The support base 204a is used to support the bracket 201d, so that the bracket 201d can provide stable support for the moving plate 201i.

[0049] When the infusion needle is pulled by the infusion tube, the movable plate 201i can be driven to move synchronously, so that the movable plate 201i can drive the driving rod 204e to move, so that the driving rod 204e drives the end of the second support rod 204c to slide in the bracket 201d. At this time, the second support rod 204c and the first support rod 204b are close to each other, so that the bracket 201d is swung upward through the support of the second support rod 204c and the first support rod 204b, thereby adjusting the angle of the movable plate 201i in the bracket 201d, so that the infusion needle in the movable plate 201i changes its angle as it moves away from the hand, allowing the infusion needle needle to move away from the hand at a suitable angle, thereby avoiding blood vessel damage caused by sudden pulling out, such as blood vessel rupture, thrombosis, etc.

[0050] Example 2, reference Figure 2~Figure 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0051] Specifically, the protection component 200 further includes a positioning member 205 disposed on one side of the wrist strap 101 , including a connecting seat 205 a fixed to one side of the wrist strap 101 , and a connecting platform 205 b is fixed to the connecting seat 205 a .

[0052] The connecting seat 205a is used to fix and support the connecting platform 205b. The setting of the connecting seat 205a is used to connect the connecting platform 205b and the wrist strap 101. According to needs, the connection method between the connecting seat 205a and the connecting platform 205b can be changed to a quick-release structure of the prior art, which is more convenient to use.

[0053] Specifically, the first connecting ball 205c is spherically connected to the connecting platform 205b, and a connecting sleeve 205d is fixed to one side of the first connecting ball 205c.

[0054] Through the spherical connection between the first connecting ball 205c and the connecting platform 205b, the connecting sleeve 205d can be transformed in any direction relative to the connecting platform 205b.

[0055] Specifically, an adjusting rod 205e is slidably connected in the connecting sleeve 205d, a fixing bolt 205f is rotatably connected in the connecting sleeve 205d through a thread, a lever 205g is fixed to the end of the fixing bolt 205f, and an extrusion groove 205e-1 is opened in the adjusting rod 205e.

[0056] By cooperating with the adjusting rod 205e and the connecting sleeve 205d, the distance between the patient's hand and the bed railing can be adjusted. By rotating the lever 205g, the fixing bolt 205f can be driven to rotate, so that the fixing bolt 205f squeezes the extrusion groove 205e-1, thereby fixing the adjusting rod 205e and the connecting sleeve 205d.

[0057] Example 3, reference Figure 1 to Figure 14 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0058] Specifically, a second connecting ball 205h is fixed to the end of the adjusting rod 205e, a fixing platform 205i is spherically connected to the surface of the second connecting ball 205h, and a mounting frame 205j is fixed to one side of the fixing platform 205i.

[0059] Through the spherical connection between the second connecting ball 205h and the fixing platform 205i, the angles of the mounting frame 205j and the adjusting rod 205e can be adjusted in any direction. The mounting frame 205j is used to be installed on the railing of the hospital bed.

[0060] Specifically, an extrusion plate 205k is slidably disposed in the mounting frame 205j, a fastening bolt 2051 is rotatably connected in the extrusion plate 205k, the fastening bolt 2051 is rotatably connected to the mounting frame 205j via a thread, and a knob 205m is fixed to the end of the fastening bolt 2051.

[0061] By turning the knob 205m, the fastening bolt 205l can be rotated relative to the mounting frame 205j, so that the fastening bolt 205l pushes the extrusion plate 205k, so that the extrusion plate 205k clamps the bed railing stuck by the mounting frame 205j, thereby completing the fixed installation of the mounting frame 205j.

[0062] In summary, the present invention has the following beneficial effects: 1. By clamping the patient's hand, it effectively prevents the needle from falling off due to hand movements such as unconscious grasping and swinging, thereby avoiding bleeding, pain and the trouble of re-puncture caused by the needle falling off; 2. When the infusion tube is pulled by external force, the device can allow the needle to be away from the hand at a suitable angle, avoiding blood vessel damage caused by sudden pulling out, such as blood vessel rupture and thrombosis. At the same time, it can also prevent the needle from retreating and injuring the blood vessel, further protecting the safety of the patient; 3. It can automatically decide whether to separate from the hand according to the movement of the needle. When the movement of the needle does not exceed 1 / 3 of the needle tube, it maintains a stable connection with the hand to ensure the continuity of the infusion; 4. When the needle moves more than 1 / 3 of the needle tube, it will automatically drive the needle to separate from the hand to prevent the needle and the blood vessels on the back of the hand from being in an unstable connection state, thereby avoiding infusion interruption or blood vessel damage caused by unstable connection.

[0063] When in use, first fix the wrist strap 101 and the hand strap 103 to the patient's hand and wrist, so as to position the connecting frame 102. At this time, the infusion needle can be inserted into the blood vessel on the back of the patient's hand, and hemostatic cotton is applied to the insertion site. At this time, the upper splint 104 and the lower splint 105 are fixed by bandages, and the connecting block 106 is snapped into the upper splint 104, so as to fix the position of the upper splint 104, so that the relative position of the upper splint 104 and the infusion needle is fixed.

[0064] When fixing the upper splint 104, by adjusting the positions of the bracket 201d and the support plate 203a, the clamping block 203b can clamp and fix the base of the infusion needle, and then the mounting frame 205j is fixed to the bed railing, thereby limiting the patient's hand and effectively preventing the needle from falling off due to hand movements such as unconscious grasping and swinging, thereby avoiding bleeding, pain and the trouble of re-puncture caused by the needle falling off.

[0065] When an external force pulls the infusion tube, the infusion needle is driven, so that the infusion needle drives the movable plate 201i to move synchronously, so that the movable plate 201i slides in the bracket 201d. At this time, the inclined surface 202b-1 of the insertion rod 202b slides from one side of the limit groove 201d-2. When the infusion needle stops moving, the insertion rod 202b is inserted into the limit groove 201d-2, so that the movable plate 201i will not move in the opposite direction after sliding, thereby preventing the infusion needle from moving back and injuring the blood vessel, thereby further protecting the patient's safety.

[0066] At the same time, the movable plate 201i can drive the driving rod 204e to move, so that the driving rod 204e drives the end of the second support rod 204c to slide in the bracket 201d. At this time, the second support rod 204c and the first support rod 204b are close to each other, so that the bracket 201d is swung upward through the support of the second support rod 204c and the first support rod 204b, thereby adjusting the angle of the movable plate 201i in the bracket 201d, so that the infusion needle in the movable plate 201i changes its angle as it moves away from the hand, allowing the infusion needle needle to move away from the hand at a suitable angle, thereby avoiding blood vessel damage caused by sudden pulling out, such as blood vessel rupture, thrombosis, etc.

[0067] If the moving stroke of the infusion needle exceeds 1 / 3 of the needle tube, the slot 201i-1 on the movable plate 201i moves to the side of the driving column 201h, and the driving column 201h can be inserted into the slot 201i-1 through the reset elastic force of the second spring 201k. At this time, the reset pulling force of the first spring 201f can drive the movable plate 201i to continue moving, so that the movable plate 201i drives the infusion needle to separate from the back of the hand, thereby removing the infusion needle and preventing the needle and the blood vessel on the back of the hand from being in an unstable connection state, thereby avoiding infusion interruption or blood vessel damage caused by unstable connection.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
