DETAILED DESCRIPTION

In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the prior art descriptions are briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary medical personnel in this field, other drawings can be obtained based on these drawings without creative work. The content of the utility model is further described below in conjunction with the drawings:

Example 1

The present embodiment relates to an infusion port butterfly needle fixing assembly, comprising a dressing 1, a covering layer 2 and a cushioning layer 3, wherein the covering layer 2 and the cushioning layer 3 are one of flexible cushioning layers such as a cotton pad, a medical absorbent gauze, a silicone pad, a sponge pad, etc.

1 , the bottom surface of the patch 1 is an adhesive surface 11 , and the covering layer 2 is fixedly arranged at the center of the bottom surface of the patch 1 ; a release paper layer is pasted on the bottom surface of the patch 1 , and the release paper layer covers the adhesive surface 11 and the covering layer 2 .

The covering layer 2 and the cushion layer 3 are square, and the area of the covering layer 2 is larger than that of the cushion layer 3. Since the size of the butterfly wing needle commonly used in the Second Xiangya Hospital of Central South University is about 3.5*2cm, the size of the covering layer 2 can be 5*3.5cm, and the size of the cushion layer 3 can be 4*2.5cm;

When in use, the cushioning layer 3 is placed under the needle tube and needle wing of the butterfly wing needle. At the same time, the covering layer 2 can completely cover the cushioning layer 3, the needle tube and needle wing of the butterfly wing needle, so that the needle tube and needle wing of the butterfly wing needle are clamped between the covering layer 2 and the cushioning layer 3, and are adhered and fixed to the skin near the puncture point by the patch 1, so as to pressurize the covering layer 2, the cushioning layer 3 and the butterfly wing needle, reduce the gap between the covering layer 2, the cushioning layer 3 and the butterfly wing needle, increase the friction between each other, and fix the position of the butterfly wing needle relative to the covering layer 2 and the cushioning layer 3.

The problem mentioned in the background technology can be solved by completely covering the cushion layer 3, the needle tube and the needle wing of the butterfly wing needle with the covering layer 2. However, if the pressure of the covering layer 2, the cushion layer 3 and the butterfly wing needle is only applied by the dressing 1 and the friction between them, the butterfly wing needle may still move during use, resulting in a poor fixation effect on the butterfly wing needle. In order to further fix the position of the butterfly wing needle between the covering layer 2 and the cushion layer 3 to prevent displacement during use;

Referring to FIG. 2 , a fixing groove for fixing the butterfly-wing needle is provided on the top surface of the cushion layer 3, and the fixing groove includes a needle-wing fixing groove 31, a needle-tube giving way groove 32 and an extension tube giving way groove 33 which are connected to each other. The needle-tube giving way groove 32 and the extension tube giving way groove 33 are respectively provided on two symmetrical sides of the needle-wing fixing groove 31, wherein the shape of the needle-wing fixing groove 31 matches the needle-wing of the butterfly-wing needle, the shape of the needle-tube giving way groove 32 matches the needle-tube of the butterfly-wing needle, the shape of the extension tube giving way groove 33 matches the extension tube of the butterfly-wing needle, and the positions of the needle-tube giving way groove 32 and the extension tube giving way groove 33 correspond to the positions of the needle-tube and the extension tube of the butterfly-wing needle;

At the same time, a fixing groove for fixing the butterfly wing needle can be provided on the bottom surface of the covering layer 2, and its purpose is the same as that of providing the fixing groove on the top surface of the cushion layer 3. Naturally, fixing grooves can be provided on both the top surface of the cushion layer 3 and the bottom surface of the covering layer 2. Although no corresponding drawings are given in the drawings of the specification, it can be associated with Figure 2;

When in use, the needle wings of the butterfly wing needle and the needle tube and extension tube parts connected to the needle wings are matched and inserted into the needle wing fixing groove 31, the needle tube giving way groove 32 and the extension tube giving way groove 33, and then covered with the covering layer 2, which can further fix the position of the butterfly wing needle and prevent displacement during use; since the thickness of the needle wing of the butterfly wing needle is about 1 mm, the depth of the needle wing fixing groove 31, the needle tube giving way groove 32 and the extension tube giving way groove 33 can be set to 1 mm, so that the needle wing is completely inserted into the needle wing fixing groove 31, and the needle tube and extension tube parts are inserted into the needle tube giving way groove 32 and the extension tube giving way groove 33.

Since the function of the cushioning layer 3 is to be placed under the needle tube and needle wing of the butterfly wing needle, so that the needle tube and needle wing do not directly contact the skin, reducing skin instrument-related pressure damage, and can also support the butterfly wing needle, and the function of the covering layer 2 is only to completely cover the cushioning layer 3, the needle tube and needle wing of the butterfly wing needle, therefore, the thickness of the cushioning layer 3 is set to be greater than the thickness of the covering layer 2. Specifically, the thickness of the cushioning layer 3 is 3mm-5mm, and the thickness of the covering layer 2 is 1mm-2mm.

During the retention process of the butterfly wing needle, it is also necessary to facilitate observation of whether the puncture point has redness, swelling, exudation, etc. If the dressing 1 is opaque, the puncture point can only be observed after the dressing 1 is torn off. Therefore, the dressing 1 uses a transparent dressing. At the same time, when installing the covering layer 2, the side edge of the cushioning layer 3 close to the puncture needle of the butterfly wing needle (that is, the side edge of the cushioning layer 3 with the needle tube yield groove 32) is aligned with a side edge of the covering layer 2, so that the puncture point will not be covered by the covering layer 2 and the cushioning layer 3, and the condition of the puncture needle can be observed through the transparent dressing.

The method of using the butterfly wing needle fixing assembly of the infusion port in this embodiment is as follows: the medical staff wears sterile gloves, takes the midpoint of the injection seat of the infusion port as the center of the circle, and disinfects it three times, with a range of 12*12cm. The medical staff palpates and locates with the left hand, uses the thumb, index finger, and middle finger to form a triangle, arches the injection seat, determines the midpoint of the three fingers, holds the butterfly wing needle with the right hand, and punctures the needle head toward the injection seat and vertically punctures from the midpoint of the injection seat to reach the bottom of the injection seat;

Take out the cushion layer 3, insert it between the butterfly wing needle and the skin, and insert the needle wing of the butterfly wing needle, the needle tube at the front end of the needle wing, and the extension tube at the rear end of the needle wing into the needle wing fixing groove 31, the needle tube clearance groove 32, and the extension tube clearance groove 33 respectively, take out the patch 1, tear off the release paper layer at the bottom, align one side edge of the covering layer 2 with the side edge of the cushion layer 3 where the needle tube clearance groove 32 is provided (refer to Figure 8), and press the covering layer 2, smooth the patch 1 from the center of the covering layer 2 to the outside, and stick the patch 1 on the skin;

When it is necessary to remove the needle (the butterfly wing needle of the infusion port needs to be replaced every 7 days) or replace the gauze, since the covering layer 2 completely covers the cushioning layer 3, the needle tube and the needle wing of the butterfly wing needle, the medical staff slowly tears off the dressing 1 from the extension tube with the right hand, and at the same time, the left hand can fix the butterfly wing needle until the dressing 1 is completely torn off. The right hand can conveniently and quickly remove and discard the dressing 1 and the covering layer 2, and the left hand can lift the butterfly wing needle as a whole to make the butterfly wing needle detach from the fixed groove, but be careful not to let the puncture needle detach from the injection seat, and then pull the cushioning layer 3 out from under the butterfly wing needle with the right hand; repeat the above steps when replacing the gauze to use the infusion port butterfly wing needle fixing assembly to fix the butterfly wing needle again. When removing the needle, the medical staff palpates and locates it with the left hand, uses the thumb, index finger and middle finger to form a triangle to fix the injection seat, holds the needle wing of the butterfly wing needle with the right hand, and pulls out the puncture needle with the back of the injection seat.

Example 2

After the infusion port butterfly wing needle is fixed by the method in Example 1, when removing the needle (the infusion port butterfly wing needle needs to be replaced every 7 days) or replacing the gauze, the padding layer 3 can only be removed after the dressing 1 and the covering layer 2 are removed, which increases the operation steps. On the one hand, it may increase the exposure time of the puncture point, and on the other hand, it is not convenient to operate. Therefore, in view of the above problems, the inventor proposes an improved solution:

Referring to Figures 3, 4, and 8, based on Example 1, the butterfly wing needle fixing assembly of the infusion port also includes a connecting belt 4 connected between the covering layer 2 and the cushioning layer 3, the two ends of the connecting belt 4 are respectively fixedly connected to the sides of the covering layer 2 and the cushioning layer 3, and a fold line 42 is provided in the middle of the connecting belt 4.

The method of using the butterfly wing needle fixing assembly of the infusion port in this embodiment is as follows: the medical staff wears sterile gloves, takes the midpoint of the injection seat of the infusion port as the center of the circle, and disinfects it three times, with a range of 12*12cm. The medical staff palpates and locates with the left hand, uses the thumb, index finger, and middle finger to form a triangle, arches the injection seat, determines the midpoint of the three fingers, holds the butterfly wing needle with the right hand, and punctures the needle head toward the injection seat and vertically punctures from the midpoint of the injection seat to reach the bottom of the injection seat;

Take out the butterfly wing needle fixing assembly of the infusion port, first place the cushion layer 3 between the butterfly wing needle and the skin, and insert the needle wing of the butterfly wing needle, the needle tube at the front end of the needle wing, and the extension tube at the rear end of the needle wing into the needle wing fixing groove 31, the needle tube clearance groove 32, and the extension tube clearance groove 33 respectively, fold the connecting belt 4 along the folding line 42, tear off the release paper layer at the bottom of the dressing 1, align one side edge of the covering layer 2 with the side edge of the cushion layer 3 where the needle tube clearance groove 32 is provided (refer to Figure 8), and press the covering layer 2, smooth the dressing 1 from the center of the covering layer 2 to the outside, and stick the dressing 1 on the skin;

When it is necessary to remove the needle (the butterfly wing needle of the infusion port needs to be replaced every 7 days) or replace the gauze, since the covering layer 2 completely covers the cushioning layer 3, the needle tube and the needle wing of the butterfly wing needle, the medical staff slowly tears off the dressing 1 from the extension tube with the right hand, and at the same time, the left hand can fix the butterfly wing needle until the dressing 1 is completely torn off, and the right hand can easily and quickly peel off the dressing 1 and the covering layer 2, and the left hand can lift the butterfly wing needle as a whole to make the butterfly wing needle disengage from the fixed groove, but be careful not to make the puncture needle disengage from the injection seat, and the right hand can move the dressing 1 and the covering layer 2 horizontally to one side to pull the cushioning layer 3 out from under the butterfly wing needle through the connecting belt 4; repeat the above steps when replacing the gauze to use the infusion port butterfly wing needle fixing assembly to fix the butterfly wing needle again. When removing the needle, the medical staff palpates and locates it with the left hand, uses the thumb, index finger and middle finger to form a triangle to fix the injection seat, holds the needle wing of the butterfly wing needle with the right hand, and pulls out the puncture needle with the back of the injection seat.

Example 3

Although the method in Example 2 can be used to remove the dressing 1, the covering layer 2 and the cushioning layer 3 in one step when removing the needle (the butterfly wing needle of the infusion port needs to be replaced every 7 days) or replacing the gauze, since the connecting belt 4 is fixedly connected between the covering layer 2 and the cushioning layer 3, when the cushioning layer 3 is padded under the butterfly wing needle, the connecting belt 4, the dressing 1 and the covering layer 2 that are integrated with the cushioning layer 3 will form a hindrance, resulting in inconvenient operation. Therefore, in view of the above problem, the inventor proposes an improved solution:

Referring to Figures 5, 6, 7, and 8, based on Example 1, the butterfly wing needle fixing assembly of the infusion port also includes a connecting belt 4 connected between the covering layer 2 and the cushioning layer 3, and adhesive layers 41 are provided at both ends of the connecting belt 4, and a release paper layer is adhered to the adhesive layer 41. The two ends of the connecting belt 4 are respectively adhered to the bottom surface of the covering layer 2 and the top surface or the bottom surface of the cushioning layer 3 through the adhesive layer 41, and a fold line 42 is provided in the middle of the connecting belt 4.

The method of using the butterfly wing needle fixing assembly of the infusion port in this embodiment is as follows: the medical staff wears sterile gloves, takes the midpoint of the injection seat of the infusion port as the center of the circle, and disinfects it three times, with a range of 12*12cm. The medical staff palpates and locates with the left hand, uses the thumb, index finger, and middle finger to form a triangle, arches the injection seat, determines the midpoint of the three fingers, holds the butterfly wing needle with the right hand, and punctures the needle head toward the injection seat and vertically punctures from the midpoint of the injection seat to reach the bottom of the injection seat;

Take out the cushion layer 3, and place the cushion layer 3 between the butterfly wing needle and the skin, and make the needle wing of the butterfly wing needle, the needle tube at the front end of the needle wing, and the extension tube at the rear end of the needle wing respectively snap into the needle wing fixing groove 31, the needle tube yielding groove 32, and the extension tube yielding groove 33, take out the connecting belt 4, tear off the release paper layer at one end to expose the adhesive layer 41, and adhere the adhesive layer 41 to the top surface or bottom surface of the cushion layer 3, fold the connecting belt 4 along the folding line 42, tear off the release paper layer at the bottom of the patch 1, tear off the release paper layer at the other end of the connecting belt 4 to expose the adhesive layer 41, and adhere the adhesive layer 41 to the bottom surface of the covering layer 2, align one side edge of the covering layer 2 with the side edge of the cushion layer 3 where the needle tube yielding groove 32 is provided (refer to Figure 8), and press the covering layer 2, smooth the patch 1 from the center of the covering layer 2 to the outside, and adhere the patch 1 to the skin;

When it is necessary to remove the needle (the butterfly wing needle of the infusion port needs to be replaced every 7 days) or replace the gauze, since the covering layer 2 completely covers the cushioning layer 3, the needle tube and the needle wing of the butterfly wing needle, the medical staff slowly tears off the dressing 1 from the extension tube with the right hand, and at the same time, the left hand can fix the butterfly wing needle until the dressing 1 is completely torn off, and the right hand can easily and quickly peel off the dressing 1 and the covering layer 2, and the left hand can lift the butterfly wing needle as a whole to make the butterfly wing needle disengage from the fixed groove, but be careful not to make the puncture needle disengage from the injection seat, and the right hand can move the dressing 1 and the covering layer 2 horizontally to one side to pull the cushioning layer 3 out from under the butterfly wing needle through the connecting belt 4; repeat the above steps when replacing the gauze to use the infusion port butterfly wing needle fixing assembly to fix the butterfly wing needle again. When removing the needle, the medical staff palpates and locates it with the left hand, uses the thumb, index finger and middle finger to form a triangle to fix the injection seat, holds the needle wing of the butterfly wing needle with the right hand, and pulls out the puncture needle with the back of the injection seat.

At the same time, the area on the covering layer 2 and the cushioning layer 3 where the adhesive layer 41 is adhered can also be marked, and the area of this area is consistent with the area of the adhesive layer 41; for example, this area can be marked with a color different from the covering layer 2 and the cushioning layer 3 themselves, and when pasting the connecting tape 4, there is no need to adjust the position on site, and only the adhesive layer 41 of the connecting tape 4 needs to be pasted on the color-marked area of the covering layer 2 and the cushioning layer 3, which can improve efficiency.

Obviously, it is possible to modify and/or add components to the above-mentioned infusion port butterfly needle fixation assembly and the corresponding method without departing from the field and scope of protection of the present utility model.

It is also clear that although the utility model has described the infusion port butterfly wing needle fixing assembly in detail, technicians in this field will certainly be able to obtain many other equivalent forms of infusion port butterfly wing needle fixing assemblies and corresponding methods. The infusion port butterfly wing needle fixing assembly and the corresponding method have the characteristics described in the claims and are therefore within the scope of the protection field defined thereby.
