Description

Technical Field

[0001] This utility model relates to the field of medical device technology; more specifically, it relates to an arm-type infusion port injection seat fixator. Background Technology

[0002] An arm-type infusion port is an advanced medical technology device designed for patients who require long-term or frequent intravenous medication. It represents a significant advancement in modern medical intravenous access technology, providing patients with a safe, convenient, and relatively painless intravenous access through a subcutaneously implanted device consisting of an injection port and catheter system.

[0003] Currently, existing arm-type infusion port injection seats are generally implanted in the patient's upper arm. Because patients' arms are frequently used in daily life, and some existing devices lack a fixation mechanism for the injection seat, the injection seat can easily migrate within the body, making long-term use of the device inconvenient and increasing the difficulty for medical staff to perform subsequent punctures. Moreover, the thickness of each patient's arm varies, requiring adjustment of the strap tightness when using the device. Some adjustable straps are not easy to disassemble, replace, or clean, and long-term use can easily breed bacteria, which is detrimental to the patient's health. Therefore, there is an urgent need for an arm-type infusion port injection seat fixation device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an arm-type infusion port injection seat fixator to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an arm-type infusion port fixator, comprising:

[0006] The outer shell has a turntable inserted inside, a groove is formed on the top surface of the turntable, and a slider is slidably inserted inside the groove. A square groove is formed through the top surface of the outer shell, and a groove is formed on one side of the outer shell. A first spring is fixed to the inner wall of the groove, and a pressure plate is fixed to one end of the first spring.

[0007] Two sets of baffles are fixed on one side of the outer shell. One set of baffles has a slot on one side surface. A pull bolt is slidably inserted into the inside of the other set of baffles. A second spring is fixed on one side of the other set of baffles. A constraint band is slidably fitted on the outer surface of one side of the pull bolt. A Velcro barbed surface is fixed on one side surface of the constraint band, and a Velcro hook surface is fixed on the other side surface of the constraint band.

[0008] Preferably, the square grooves are provided in six groups, and the six groups of square grooves are evenly distributed on one side of the outer shell in a circular array, so that the deflection of the multiple groups of sliders does not affect each other.

[0009] Preferably, one end of the slider is a cylinder that fits into a square groove and slides inside the groove. The middle of the slider is a triangular block, and there are six sets of triangular blocks. The six sets of triangular blocks are evenly distributed in a circular array. The surface of the triangular blocks is covered with a silicone pad. The other end of the slider is a protrusion that fits into a sliding groove and slides inside the groove. This protrusion restricts the movement direction of the six sets of sliders, causing them to deflect and thus clamping the injection seat.

[0010] Preferably, a first circular hole is formed through the top surface of the outer shell, and a second circular hole is formed through the middle surface of the turntable. The diameter of the second circular hole is smaller than the inner diameter of the slide groove, which facilitates puncture operations by medical personnel.

[0011] Preferably, one end of the pull bolt is a large cylinder, and one side of the large cylinder is fixedly connected to one end of the second spring. The other end of the pull bolt is a small cylinder, and the second spring is slidably sleeved on the outer surface of the small cylinder. The size of the small cylinder is adapted to the slot, and the small cylinder slides inside the slot, so that the pull bolt will not detach from the inside of the slot without the action of external force.

[0012] Preferably, the restraint straps are configured as two symmetrical sets, one set of restraint straps having its outer side fixedly connected to the hook and loop surface of the Velcro, and the other set of restraint straps having its inner side fixedly connected to the hook and loop surface of the Velcro, so as to facilitate fixing the outer shell to the patient's arm through the structure between the hook and loop surface of the Velcro.

[0013] The technical effects and advantages of this utility model are as follows: Through the coordinated use of the outer shell, turntable, slide, slider, square groove, groove, first spring and pressure plate, this utility model can fix injection seats of different sizes by rotating the turntable, thereby reducing the possibility of the injection seats moving during the patient's daily activities and providing convenience for medical staff to perform injections.

[0014] The device utilizes a combination of baffles, slots, bolts, a second spring, restraint straps, and the combination of hook and loop fasteners to easily bind patients with varying arm sizes. The restraint straps are also designed to be detachable, facilitating daily replacement and cleaning by medical staff, reducing bacterial residue on the strap surface, and providing patients with greater peace of mind, thus improving the device's safety.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] like Figures 1 to 6As shown, this embodiment proposes an arm-type infusion port fixation device, including a housing 1. A turntable 2 is rotatably inserted inside the housing 1. A groove 3 is formed on the top surface of the turntable 2, and a slider 4 is slidably inserted inside the groove 3. A square groove 5 is formed through the top surface of the housing 1. A groove 6 is formed on one side of the housing 1. A first spring 7 is fixed to the inner wall of the groove 6, and a pressure plate 8 is fixed to one end of the first spring 7. Six sets of square grooves 5 are formed and evenly distributed on one side of the housing 1 in a circular array. The slider 4... One end of the slider 4 is set as a cylinder, which is adapted to the square groove 5. The cylinder slides inside the square groove 5. The middle of the slider 4 is set as a triangular block. There are six sets of triangular blocks. The six sets of triangular blocks are evenly distributed in a circular array. The surface of the triangular blocks is covered with silicone pads. The other end of the slider 4 is set as a protrusion, which is adapted to the slide groove 3. The protrusion slides inside the slide groove 3. The top surface of the outer shell 1 is provided with a first circular hole. The middle surface of the turntable 2 is provided with a second circular hole. The diameter of the second circular hole is smaller than the inner diameter of the slide groove 3.

[0026] In this embodiment, when it is necessary to fix the injection seat, firstly, align the bottom of the outer shell 1 with the injection seat and press down forcefully so that the injection seat enters the second circular hole of the turntable 2. Since the size of different models of injection seats will vary, the turntable 2 needs to be rotated. Also, because the first spring 7 inside the groove 6 has elasticity, the first spring 7 keeps pressing the pressure plate 8 downward. At the same time, the pressure plate 8 presses one end of the turntable 2 in the same direction, so that the turntable 2 can remain stable without a large external force. Therefore, force is required when rotating the turntable 2. While the turntable 2 rotates, it drives the slide groove 3 to rotate in the same direction. The rotation of the slide groove 3 causes the protrusion of the slider 4 inside to move. However, the column of the slider 4 is located inside the square groove 5, so that the column of the slider 4 slides inside the square groove 5 during the movement of the protrusion of the slider 4. The square groove 5 is fixed, so that the triangular block of the slider 4 deflects during the movement of the slider 4, thereby pressing the injection seat in the second circular hole. When the appropriate force is reached, the rotation of the turntable 2 can be stopped.

[0027] Example 2

[0028] like Figure 1 and Figure 7As shown, based on the same concept as the above embodiment, this embodiment also proposes: two sets of baffles 9 are fixed on one side of the outer shell 1. One set of baffles 9 has a slot 10 on one side surface. A pull bolt 11 is slidably inserted inside the other set of baffles 9. A second spring 12 is fixed on one side of the other set of baffles 9. A constraint band 13 is slidably sleeved on one side outer surface of the pull bolt 11. A Velcro barbed surface 14 is fixed on one side surface of the constraint band 13. A Velcro hook surface 15 is fixed on the other side surface of the constraint band 13. One end of the pull bolt 11 is set as a large cylinder, and one side of the large cylinder is fixedly connected to one end of the second spring 12. The other end of the pull bolt 11 is set as a small cylinder. The second spring 12 is slidably sleeved on the outer surface of the small cylinder. The size of the small cylinder is adapted to the slot 10. The small cylinder slides inside the slot 10. The constraint band 13 is set as two symmetrical sets. The outer side of one set of constraint band 13 is fixedly connected to the Velcro barbed surface 14. The inner side of the other set of constraint band 13 is fixedly connected to the Velcro hook surface 15.

[0029] In this embodiment, when the fixation device needs to be worn on the patient's arm, first align the bottom of the outer shell 1 with the injection port, so that the injection port is located inside the outer shell 1. Then, first pull the restraint strap 13 with the hook and loop fastener 14 on one side to wrap around and tightly fit the skin of the patient's arm. Next, pull the restraint strap 13 with the hook and loop fastener 15 on one side to wrap around and tightly fit the patient's arm, and cover the surface of the hook and loop fastener 14 with the hook and loop fastener 15. The hook and loop fastener 14 and hook and loop fastener 15 are existing structures. At this time, the device is fixed. When the restraint strap 13 needs to be replaced or cleaned... At this time, the pull bolt 11 can be pulled, so that one end of the small cylinder of the pull bolt 11 slides out from the inside of the slot 10 and slides outward along the inside of the baffle 9. At the same time, the pull bolt 11 drives the second spring 12 to stretch in the same direction. When the pull bolt 11 is pulled to the appropriate position, the restraint band 13 can be slid out from the outer surface of the small cylinder of the pull bolt 11. At this time, the restraint band 13 can be replaced and cleaned. After the operation is completed, the restraint band 13 is slid back onto the outer surface of the small cylinder, and then the pull bolt 11 is released. The pull bolt 11 will slide back into the inside of the slot 10 under the elastic force of the second spring 12.

[0030] Working principle: When using the device, first place the outer shell 1 above the injection seat. Because there will be obvious protrusions on the skin when the injection seat is placed in the patient's upper arm, press the outer shell 1 downwards to make the injection seat slide into the second round hole of the turntable 2. Then pull the restraint straps 13 so that the two sets of restraint straps 13 wrap around and fit tightly against the patient's arm. It is important to pay attention to the staggered order of the two sets of restraint straps 13. The hook and loop side 15 of the hook and loop side 14 should be covered over the hook and loop side 14. After the hook and loop side 14 and the hook and loop side 15 are tightly fitted, the turntable 2 can be rotated to make the six sets of sliders 4 fit tightly against the injection seat, thereby preventing the injection seat from moving inside the patient's body when the patient is using the arm. When puncture is required, the medical staff only needs to insert the puncture needle into the injection seat through the first round hole at the top of the outer shell 1. The above is the complete working principle of this device.

[0031] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
