Abstract
Description
Technical Field
[0001] The present application relates to the technical field of infusion port locators, and in particular to an infusion port puncture locator. Background Art
[0002] An infusion port is a component used to connect an infusion tube or needle in a medical device, usually used for intravenous infusion or injection of drugs. It can provide a safe and clean channel to ensure that the drug can be accurately delivered into the patient's body while avoiding the risk of contamination and infection. It includes a central venous catheter and a puncture seat connected to the end of the catheter. The central venous catheter is placed in a large blood vessel of the human body, such as the subclavian vein, superior vena cava, etc., through subcutaneous puncture by surgical methods. Part of the catheter is buried in the subcutaneous tissue, and the puncture seat is left in the subcutaneous tissue of the chest wall and sutured and fixed.
[0003] In clinical practice, when medical staff use a non-destructive needle to puncture the infusion port, they first touch the skin at the corresponding position of the infusion port with their hand and observe a bulge. Then, they use their thumb, index finger, and middle finger to form a triangle and arch the injection seat of the infusion port. With the other hand, they hold the non-destructive needle vertically into the puncture septum from the center of the three fingers (do not over-tighten the skin) to reach the bottom of the reservoir base.
[0004] However, in the prior art, when medical staff use a non-destructive needle to puncture the infusion port, they usually use an infusion port locator to assist in the puncture. However, the existing infusion port locator cannot indicate the center of the infusion port (the center of three fingers). Therefore, medical staff can only use the non-destructive needle to puncture the infusion port based on subjective judgment during puncture. However, if the non-destructive needle deviates far from the center of the infusion port during puncture, the puncture diaphragm of the infusion port will be aggravated, resulting in a reduced service life of the infusion port and an increased cost of using the infusion port.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0035] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as they do not conflict with each other.
[0036] The utility model provides Figures 1 to 3 As shown in the figure, an infusion port puncture locator is intended to solve the deficiency that the existing infusion port locator cannot indicate the center of the infusion port.
[0037] The infusion port puncture locator mainly comprises: a locator body 101 , a fixed locating portion 201 , two movable locating portions 301 and a synchronous sliding assembly 400 . The fixed locating portion 201 and the synchronous sliding assembly 400 are both arranged on the locator body 101 .
[0038] The two movable positioning parts 301 are arranged at intervals from the fixed positioning part 201. When in use, the fixed positioning part 201 and the two movable positioning parts 301 are in contact with the infusion port. The triangle formed by the three contact points can determine the position of a circle (infusion port) through three points, so the circumcenter of the triangle is the center of the circle (infusion port) passing through the three contact points. As is known to all, the circumcenter of a triangle is the intersection of the perpendicular bisectors of the three sides, so the circumcenter of the triangle must be on the perpendicular bisector of one side of the triangle. Since the two movable positioning parts 301 are arranged on the synchronous sliding assembly 400, the synchronous sliding assembly 400 is used to control the two movable positioning parts 301 to approach or move away synchronously, so that the position of the perpendicular bisector of the straight line (equivalent to one side of the above-mentioned triangle) formed by the two movable positioning parts 301 remains unchanged. The fixed positioning part 201 is located on the puncture part, and the puncture part is located on the perpendicular bisector of the straight line formed by the two movable positioning parts 301. Therefore, the relative position of the puncture part on the locator body 101 remains unchanged, and the circumcenter of the triangle (the center of the infusion port) is located on the puncture part.
[0039] During actual use, the medical staff moves the infusion port puncture locator, adjusts the infusion port to between the two movable positioning parts 301 and the fixed positioning part, then brings the fixed positioning part 201 close to the infusion port, and then presses one or two of the movable positioning parts 301 with a finger, so that the two movable positioning parts 301 are synchronously close, until the two movable positioning parts 301 and the fixed positioning part 201 clamp the infusion port. At this time, the center of the infusion port is located on the puncture part. When the medical staff punctures the puncture part, the error in subjectively judging the center of the infusion port can be reduced, thereby reducing the wear on the puncture diaphragm of the infusion port.
[0040] However, in the prior art, when medical staff use a non-destructive needle to puncture the infusion port, they usually use an infusion port locator to assist in the puncture. However, the existing infusion port locator cannot indicate the center of the infusion port (the center of three fingers). Therefore, medical staff can only use the non-destructive needle to puncture the infusion port based on subjective judgment during puncture. However, if the non-destructive needle deviates far from the center of the infusion port during puncture, the puncture diaphragm of the infusion port will be aggravated, resulting in a reduced service life of the infusion port and an increased cost of using the infusion port.
[0041] The utility model can fix the infusion port between the three by setting a fixed positioning part 201 and two movable positioning parts 301. The contact points of the three and the infusion port form a triangle, and the center of the infusion port is the circumcenter of the triangle; the synchronous sliding component 400 makes the two movable positioning parts 301 approach or move away from each other at the same rate, so that the position of the perpendicular bisector of the straight line formed by the two movable positioning parts 301 remains unchanged. According to the principle that the circumcenter of the triangle is the intersection point of the perpendicular bisectors of the three sides, it can be known that the center of the infusion port is always located on the puncture part. When medical staff perform puncture on the puncture part, the error in subjectively judging the center of the infusion port can be reduced, thereby reducing the wear on the puncture diaphragm of the infusion port.
[0042] In some embodiments, Figure 1 to Figure 2 As shown in the figure, the fixed positioning part 201 and the two movable positioning parts 301 are both arc-shaped, and the centers of the fixed positioning part 201 and the two movable positioning parts 301 are both located on the puncture part. The surface in contact with the infusion port is an arc surface, which can reduce the irritation of the fixed positioning part 201 and the two movable positioning parts 301 to the patient's skin when fixing the infusion port, and can also increase the contact area between the fixed positioning part 201 and the two movable positioning parts 301 and the infusion port, so that the infusion port puncture locator is more stable when fixing the infusion port.
[0043] In some embodiments, Figure 1 to Figure 2 As shown in the figure, the two movable positioning parts 301 are rotatably arranged on the synchronous sliding assembly 400. When fixing infusion ports of different diameters, the arc surfaces of the two movable positioning parts 301 can be rotated, which can increase the contact area between the fixed positioning part 201 and the two movable positioning parts 301 and the infusion port, so that the infusion port puncture locator is more stable when fixing the infusion port.
[0044] In some embodiments, Figures 1 to 3 As shown in , the synchronous sliding assembly 400 includes: a slide rail 401, two movable positioning parts 301 are slidably arranged on the slide rail 401, the slide rail 401 is perpendicular to the puncture part, and the puncture part is located in the middle of the slide rail 401;
[0045] Two rotating shafts 402, which are arranged at two ends of the slide rail 401;
[0046] Belt 403, two rotating shafts 402 are arranged inside the belt 403, the two rotating shafts 402 are connected by the belt 403 transmission, and the two movable positioning parts 301 are respectively fixedly arranged at opposite ends of the belt 403, and the belt 403 is used to control the two movable positioning parts 301 to approach or move away synchronously. The above structure can refer to the slide rail 401 of the electric curtain. When the two movable positioning parts 301 approach each other synchronously, it is like the electric curtain closing the curtain; when the two movable positioning parts 301 move away from each other at the same rate, it is like the electric curtain opening the curtain. In actual use, the medical staff pushes one of the movable positioning parts 301, and the movable positioning part 301 drives the belt 403 to rotate, and then pushes the other movable positioning part 301 to move synchronously, so that the two movable positioning parts 301 can move synchronously.
[0047] In some embodiments (not shown), the synchronous sliding assembly 400 includes: a gear, which is disposed between the two movable positioning parts 301;
[0048] Two racks, both of which are perpendicular to the puncture part, are slidably arranged on the positioner body 101 along their length direction, a gear is arranged between the two racks, and the gear and the two racks are meshed with each other, and the ends of the two racks that are away from each other are fixedly connected to the two movable positioning parts 301. When the medical staff pushes one of the movable positioning parts 301, the movable positioning part 301 moves with one of the racks, and the rack drives the gear to rotate, thereby driving the other rack to move synchronously, so that the two movable positioning parts 301 move synchronously.
[0049] In some embodiments, Figure 1 to Figure 2 As shown in the figure, the infusion port puncture locator also includes: a puncture slot 102, which is arranged on the locator body 101, and the puncture slot 102 is arranged on the puncture part. The puncture slot 102 is used to expose part of the patient's skin. In actual use, after the medical staff clamps the infusion port through the infusion port puncture locator, they can puncture the exposed skin on the puncture slot 102. Since the puncture slot 102 is a straight line, when the medical staff confirms the midpoint of the infusion port, it can be changed from the original whole surface to a line, which greatly reduces the error;
[0050] The notch portion 103, the puncture slot 102 penetrates the locator body 101 at one end close to the fixed positioning portion 201 to form the notch portion 103, and the notch portion 103 is used to pass the non-destructive needle. After the puncture is completed, the medical staff needs to remove the infusion port puncture locator. At this time, the non-destructive needle can leave through the notch portion 103, thereby removing the infusion port puncture locator.
[0051] In some embodiments, the infusion port puncture locator further includes: a transparent window, which is disposed on the locator body 101 and is located between the fixed positioning portion 201 and the two movable positioning portions 301, and is used to observe the patient's skin, so that medical staff can observe the location when looking for the infusion port.
[0052] In some embodiments, Figure 1 to Figure 2 As shown in , the infusion port puncture locator also includes: a circle center indicator 500, which is used to indicate the circle center of the infusion port. The infusion port is located between the fixed positioning part 201 and the two movable positioning parts 301, and the fixed positioning part 201 and the two movable positioning parts 301 are both in contact with the infusion port through the patient's skin. Through the circle center indicator 500, medical staff can avoid subjective judgment and guessing the circle center of the infusion port, and reduce the wear of the puncture diaphragm of the infusion port during puncture.
[0053] In some embodiments, Figure 1 to Figure 2 As shown in , the circle center indicator 500 includes: a position detection component 501, the position detection component 501 is used to detect the positions of the two movable positioning parts 301;
[0054] The indicator area is arranged on the locator body 101 and is parallel to the puncture portion. The indicator area is used to display the position of the center of the infusion port.
[0055] In some embodiments, Figure 1 to Figure 2 As shown in , the position detection assembly 501 includes: a split displacement sensor, the split displacement sensor includes: a sensor body and a measuring part, the sensor body and the measuring part are respectively arranged on one of the movable positioning parts 301 and the positioner body 101;
[0056] Display 502, display 502 is used to display the position of the center of the infusion port. It can be understood that since the position of the fixed positioning part 201 does not change, the position of the infusion port can be determined by the position of the movable positioning part 301, and then the position of the center of the infusion port can be determined, that is, the position of the movable positioning part 301 corresponds to the position of the center of the infusion port. The position of the movable positioning part 301 and the position of the center of the infusion port are recorded, and the position of the center of the infusion port can be obtained by the position of the movable positioning part 301, and then displayed on the display 502. When puncturing, medical staff can directly align with the center of the infusion port displayed on the display 502 to perform puncture, thereby reducing the wear on the puncture diaphragm of the infusion port. It should be noted that how to realize the display of the center of the infusion port on the display 502 in hardware according to the above principle is a prior art, and the above work can be achieved through an ordinary single-chip microcomputer.
[0057] In summary, an infusion port puncture locator is provided, including a locator body, a fixed positioning part, two movable positioning parts and a synchronous sliding assembly, wherein the two movable positioning parts are arranged on the synchronous sliding assembly, the fixed positioning part is located on the puncture part, and the synchronous sliding assembly is used to control the two movable positioning parts to approach or move away synchronously, and the puncture part is located on the perpendicular bisector of the straight line formed by the two movable positioning parts. The utility model fixes the infusion port by arranging the fixed positioning part and the movable positioning part, and the circumcenter of the triangle formed by the three is the center of the infusion port; the synchronous sliding assembly can keep the position of the puncture part unchanged, and according to the principle that the circumcenter of the triangle is the intersection of the perpendicular bisectors of the three sides, it can be known that the center of the infusion port is always located on the puncture part, and medical staff can reduce the error in subjectively judging the center of the infusion port by puncturing the puncture part, thereby reducing the wear on the puncture diaphragm of the infusion port.
[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
