[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The present application is further described in detail below in conjunction with the accompanying drawings.

[0044] The embodiments of the present application disclose an injection operation fixture and method.

[0045] like Figure 1 As shown, an injection operation fixture comprises a fixed base member 1, a pressing member 2 and a supporting device 3. The fixed base member 1 is made of a bendable material and is used to be attached to the site to be injected; two pressing members 2 are provided, and the two pressing members 2 are respectively provided on both sides of the fixed base member 1, and a finger penetration hole 211 is provided on the pressing member 2; the supporting device 3 is provided on the fixed base member 1, and the supporting device 3 is inclined on the fixed base member 1, and the supporting device 3 is used to support the syringe.

[0046] When the operator uses the injection operation fixture, he places the fixed base member 1 on the patient's injection site, such as the arm, and then the operator inserts two fingers of one hand into the finger holes 211 on the pressing members 2 on both sides of the fixed base member 1, and applies pressure to the two pressing members 2 with two fingers. The fixed base member 1 can be bent and tightly attached to the patient's injection site. At this time, the other hand places the syringe against the supporting device 3. Since the supporting device 3 is tilted on the fixed base member 1, the needle of the syringe can be aligned with the injection site. After that, the medical staff can stably perform the injection operation with the hand that touches the syringe.

[0047] The patent application realizes two-handed operation through the injection operation fixture. One hand is responsible for the stability of the injection operation fixture, and the other hand is responsible for the injection operation. Compared with the single-handed operation in the prior art that needs to be responsible for both support and injection operations, the stability of the injection operation is greatly improved. At the same time, since the supporting device 3 is tilted on the fixed base 1, a stable tilt angle is provided for the operator. The operator only needs to place the syringe against the supporting device 3 to obtain a stable injection angle, which once again improves the stability of the injection operation and solves the problem of instability when the operator uses one-hand support to perform the injection operation.

[0048] like Figure 1 , Figure 2 and Figure 3As shown, the supporting device 3 includes a supporting fixing member 31 and a supporting assembly 32. The supporting fixing member 31 is arranged on the fixed base member 1, and the supporting assembly 32 is inclinedly arranged on the supporting fixing member 31. The angle between the supporting assembly 32 and the supporting fixing member 31 is greater than or equal to zero degrees, and the angle between the supporting assembly 32 and the supporting fixing member 31 is less than or equal to ninety degrees.

[0049] Specifically, the fixing base member 1 is in the shape of a rectangular strip and is made of a flexible material to facilitate the fixing base member 1 to bend and better fit the patient's injection site.

[0050] The pressing pieces 2 are arranged at the left and right ends of the fixed base member 1, and the two pressing pieces 2 are both arranged on the central axis of the fixed base member 1 along the left and right directions, so that when the operator presses the pressing pieces 2 on the left and right sides of the fixed base member 1, no tangential force perpendicular to the central axis of the pressing pieces 2 in the left and right directions will be generated, thereby improving the stability of the injection operation fixture during use.

[0051] The pressing member 2 includes a pressing portion 21 and a connecting portion 22 . The pressing portion 21 is cylindrical in shape. The finger hole 211 is a through hole. The finger hole 211 passes through the upper and lower ends of the pressing portion 21 .

[0052] One end of the connecting portion 22 is arranged on the side wall of the pressing member 2, and the other end is arranged on one end of the fixing base member 1. The connecting portion 22 is made of a bendable material and can be attached to the injection site together with the fixing base member 1.

[0053] When using the injection operation fixture, taking the use of the syringe by the right hand as an example, two fingers of the operator's left hand respectively pass through the finger holes 211. The two fingers respectively apply an oblique downward force to the pressing part 21, and the pressing parts 2 on both sides of the fixed base member 1 can straighten the fixed base member 1 and stably fit the patient's injection site.

[0054] The supporting fixing member 31 is in a rectangular shape and is disposed on the upper surface of the fixing base member 1 . The line connecting the center of the supporting fixing member 31 and the center of the supporting fixing member 31 is perpendicular to the supporting fixing member 31 .

[0055] It should be noted that the entire lower surface of the supporting fixing member 31 is not fixed on the fixing base member 1 , and the connection between the supporting fixing member 31 and the fixing base member 1 is only concentrated at their respective centers, which does not affect the bending of the fixing group.

[0056] The supporting assembly 32 is tiltedly arranged on the supporting fixture 31 . When the syringe abuts against the supporting assembly 32 , the angle between the syringe needle and the skin is approximately the angle between the supporting assembly 32 and the supporting fixture 31 .

[0057] The angle between the supporting assembly 32 and the supporting fixture 31 ensures that the syringe is at the optimal injection angle each time the supporting device 3 is used for an injection operation, which facilitates the operator's injection operation and reduces the risk of damaging major nerves and blood vessels due to inaccurate injection angles of the syringe.

[0058] The supporting component 32 also has a guiding function. The operator can press the pressing part 2 downward with one hand to make the fixed base 1 only stick to the injection site, and use the other hand to operate the syringe to press against the supporting component 32, and push it downward along the supporting component 32 to penetrate the skin of the patient's injection site to perform the injection operation, thereby completing the injection operation stably and conveniently.

[0059] like Figure 1 and Figure 3 As shown, one end of the supporting component 32 is rotatably set on the supporting fixing member 31; the supporting device 3 includes an angle adjustment component 33, one end of the angle adjustment component 33 is set on the supporting fixing member 31, and the other end abuts on the supporting component 32. The height of the angle adjustment component 33 is adjustable, and is used to adjust the angle between the supporting fixing member 31 and the supporting component 32.

[0060] Specifically, the supporting component 32 is rotatably disposed on the supporting fixture 31 , and the operator can adjust the angle between the supporting component 32 and the supporting fixture 31 according to the patient's skin and fat thickness.

[0061] For example, in clinical practice, the best angle for subcutaneous injection by nurses is generally 30 to 40 degrees, but in certain cases, such as when using a short needle or a specific drug, a vertical needle insertion method of 90 degrees or close to 90 degrees can be used. At this time, the operator can choose the appropriate needle insertion angle according to the patient's specific situation and the characteristics of the drug.

[0062] The angle adjustment member is arranged on the upper surface of the supporting fixing member, and the angle adjustment member is located below the lower surface of the supporting assembly 32. The angle adjustment member is in the shape of a rod, one end of which is arranged on the supporting fixing member 31, and the supporting assembly 32 will abut against the other end of the angle adjustment member under the action of gravity, so the angle between the supporting assembly 32 and the supporting fixing member 31 can be adjusted by adjusting the height of the angle adjustment member.

[0063] like Figure 3 , Figure 7 , Figure 8 and Fig. 9As shown, the angle adjustment assembly 33 includes an angle adjustment fixing member 331, a height adjustment member 332 and a clamping member 333. One end of the angle adjustment fixing member 331 is arranged on the supporting fixing member 31, and the other end is provided with a receiving hole 3311. The side wall of the angle adjustment fixing member 331 is provided with an adjustment hole 3312 and a clamping hole 3313. The adjustment hole 3312 is arranged along the axial direction of the angle adjustment fixing member 331, and a plurality of clamping holes 3313 are provided. A plurality of snap-fit ​​holes 3313 are arranged at intervals on the adjustment hole 3312, each snap-fit ​​hole 3313 is connected to the adjustment hole 3312, and the adjustment hole 3312 and each snap-fit ​​hole 3313 are connected to the accommodating hole 3311; the snap-fit ​​member 333 is arranged on the height adjustment member 332, the height adjustment member 332 is slidably arranged in the accommodating hole 3311, the snap-fit ​​member 333 extends from the adjustment hole 3312, and the snap-fit ​​member 333 is used to snap-fit ​​with the snap-fit ​​hole 3313.

[0064] Specifically, the angle adjustment fixing member 331 and the height adjustment member 332 are both rod-shaped, one end of the angle adjustment fixing member 331 is arranged on the upper surface of the supporting fixing member 31, and the angle adjustment fixing member 331 is vertically arranged on the supporting fixing member 31. The accommodating hole 3311 is arranged on the other end of the angle adjustment fixing member 331, one end of the height adjustment member 332 is inserted into the accommodating hole 3311, the height adjustment member 332 can slide up and down on the angle adjustment fixing member 331 along the accommodating hole 3311, and the other end of the height adjustment member 332 can abut against the lower surface of the supporting assembly 32.

[0065] The adjustment hole 3312 is a longitudinal hole, and the adjustment hole 3312 is arranged along the axial direction of the angle adjustment fixing member 331 . The opening shape of the adjustment hole 3312 is a longitudinal strip opening perpendicular to the supporting fixing member 31 .

[0066] The snap-in hole 3313 is a transverse hole, and the snap-in hole 3313 is arranged along the radial direction of the angle adjustment fixing piece 331. The opening shape of the snap-in hole 3313 is a transverse strip opening parallel to the supporting fixing piece 31. Each snap-in hole 3313 can be connected to the adjustment hole 3312 at only one end (that is, the snap-in hole 3313 is arranged on one side of the adjustment hole 3312), or the snap-in hole 3313 can be passed through the adjustment hole 3312 (that is, the snap-in hole 3313 is arranged on both sides of the adjustment hole 3312, for example, the midpoint of the snap-in hole 3313 is located on the adjustment hole 3312, and there are snap-in holes 3313 on both sides of the adjustment hole 3312).

[0067] The multiple snap-in holes 3313 are all connected to the adjustment hole 3312. The multiple snap-in holes 3313 can be set on the same side of the adjustment hole 3312, or on different sides, or on both sides of the adjustment hole 3312. There is no limitation to this herein.

[0068] One end of the clamping member 333 is located in the accommodating hole 3311 and is vertically arranged with respect to the height adjusting member 332 in the accommodating hole 3311 , and the other end thereof protrudes from the adjusting hole 3312 .

[0069] The clamping member 333 is rotated so that the clamping member 333 is located in the adjustment hole 3312, and then the height adjustment member 332 is moved up and down by the clamping member 333. Since one end of the height adjustment member 332 abuts against the supporting component 32, during the process of the height adjustment member 332 moving up and down, the angle between the supporting component 32 and the supporting fixing member 31 also changes accordingly. When the angle between the supporting component 32 and the supporting fixing member 31 is adjusted to a suitable angle range, the up and down movement of the height adjustment member 332 is stopped, and then the clamping member 333 is rotated so that it rotates to the clamping hole 3313 corresponding to the current suitable angle range, so as to fix the height of the angle adjustment member 33. Since the supporting component 32 abuts against the height adjustment member 332 due to gravity, the angle between the supporting component 32 and the supporting fixing member 31 will be fixed, which is convenient for the operator to place the syringe on the supporting component 32 for injection.

[0070] like Figure 3 As shown, the supporting device 3 includes an angle observation member 334 , which is disposed on the supporting fixing member 31 , and is used to display the size of the angle between the current supporting fixing member 31 and the supporting assembly 32 .

[0071] Specifically, the angle observation piece 334 is fan-shaped, and continuous angle values ​​are marked on the angle observation piece 334. The rotation axes of the supporting fixing piece 31 and the supporting component 32 are coaxially arranged with the central angle of the angle observation piece 334. The 0-degree line on the angle observation piece 334 is arranged to coincide with the supporting fixing piece 31, and the angle value corresponding to the supporting component 32 is the angle between the current supporting component 32 and the supporting fixing piece 31.

[0072] Before the operation, the operator will evaluate the thickness of the patient's subcutaneous fat at the injection site to determine the depth and angle of the needle. The needle insertion angle of the syringe (i.e. the angle between the supporting component and the supporting fixture) must be adjusted in advance. At this time, the angle observation piece from the side of the supporting fixture can be directly observed.

[0073] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the supporting assembly 32 includes a supporting base 321 and a length adjusting member 322 . The supporting base 321 is tiltedly arranged on the supporting fixing member 31 , and the length adjusting member 322 is slidably arranged at one end of the supporting base 321 . The length adjusting member 322 is used to adjust the length of the supporting assembly 32 .

[0074] Specifically, one end of the supporting base 321 is rotatably disposed on the supporting fixing member 31 , and the lower surface of the supporting base 321 abuts against the end of the height adjusting member 332 .

[0075] The length adjusting member 322 is slidably disposed on the upper surface of the supporting base 321 , and the position of the length adjusting member 322 on the supporting base 321 can be adjusted to change the length of the supporting assembly 32 to adapt to the length of the syringe.

[0076] Furthermore, a first sliding groove 3211 is provided on the upper surface of the supporting base 321 , and a first sliding block 3221 is provided on the lower surface of the length adjusting member 322 . The first sliding block 3221 is disposed in the first sliding groove 3211 , and the first sliding block 3221 can slide along the first sliding groove 3211 .

[0077] It should be noted that the first sliding groove 3211 and the first sliding block 3221 are in sliding friction fit, and there is friction between the first sliding groove 3211 and the first sliding block 3221. External force needs to be applied to overcome the friction between the first sliding groove 3211 and the first sliding block 3221 to enable the first sliding block 3221 to slide in the first sliding groove 3211.

[0078] Furthermore, the first sliding groove 3211 is a dovetail groove, and the first sliding block 3221 is a dovetail slider. The inclination angle design of the dovetail groove and the dovetail slider enables a self-locking function under certain conditions. When the first sliding block 3221 is subjected to an external force along the sliding direction, as long as the external force does not exceed a certain limit, the first sliding block 3221 will not slide on its own; at the same time, the inclination angle design of the dovetail groove and the dovetail slider can effectively prevent the slider from shifting in a direction perpendicular to the sliding direction, thereby increasing the stability of the sliding friction fit between the first sliding groove 3211 and the first sliding block 3221.

[0079] The length direction mentioned above is the direction parallel to the axial direction of the syringe after the syringe is placed on the supporting assembly 32 .

[0080] like Figure 3 , Figure 4 and Figure 5 As shown, the supporting assembly 32 includes a width adjusting member 323 , which is slidably disposed on one side of the supporting base 321 , and is used to adjust the width of the supporting assembly 32 .

[0081] Specifically, the width adjusting member 323 is slidably disposed on the lower surface of the supporting base 321 , and the position of the width adjusting member 323 on the supporting base 321 can be adjusted to change the width of the supporting assembly 32 to adapt to the diameter of the syringe.

[0082] Furthermore, a second sliding groove 3212 is provided on the lower surface of the supporting base 321 , and a second sliding block 3231 is provided on the upper surface of the width adjusting member 323 . The second sliding block 3231 is disposed in the second sliding groove 3212 , and the second sliding block 3231 can slide along the second sliding groove 3212 .

[0083] The second sliding groove 3212 is a dovetail groove, and the second sliding block 3231 is a dovetail slider. The inclination angle design of the dovetail groove and the dovetail slider can effectively prevent the slider from shifting in a direction perpendicular to the sliding direction, thereby preventing the width adjustment member 323 from falling off the supporting base 321, thereby increasing the stability of the cooperation between the supporting base 321 and the width adjustment member 323. At the same time, the dovetail groove and the dovetail slider are in sliding friction cooperation, and the inclination angle design between the dovetail groove and the dovetail slider has a self-locking function under certain conditions. When the second sliding block 3231 is subjected to external force along the sliding direction, as long as the external force does not exceed a certain limit, the second sliding block 3231 will not slide by itself, thereby increasing the stability of the sliding friction cooperation between the second sliding groove 3212 and the second sliding block 3231.

[0084] The width direction mentioned above is the direction perpendicular to the axial direction of the syringe after the syringe is placed on the supporting assembly 32 .

[0085] It should be noted that the width adjustment member 323 and the angle observation member 334 are located on both sides of the supporting base 321 to facilitate the operator to observe the angle.

[0086] like Figure 3 and Figure 4 As shown, the supporting component 32 is an arc-shaped plate.

[0087] Specifically, the arc-shaped plate design of the supporting component 32 can better adapt to and fit the tube wall of the syringe, thereby increasing the stability of the syringe abutting against the supporting component 32 .

[0088] To facilitate the support assembly 32 to better adapt to the tube wall of the syringe after the length and width are adjusted, the support base 321, the length adjustment member 322 and the width adjustment member 323 are all arc-shaped plates, and the support base 321, the length adjustment member 322 and the width adjustment member 323 are coaxially arranged.

[0089] When the supporting component 32 is an arc-shaped plate, the function of the width adjusting member 323 is no longer to adjust the width of the supporting component 32 but to enable the supporting component 32 to adapt to the size of a syringe with a larger diameter.

[0090] like Fig.10 As shown, an injection operation method is applied to any of the above injection operation fixtures, the method comprising:

[0091] S100, applying pressure to the pressing members 2 on both sides of the fixed base member 1 simultaneously, so that the fixed base member 1 is closely attached to the area to be injected.

[0092] Specifically, taking the injection site as the middle and lower section of the outer side of the patient's forearm as an example, the lower surface of the fixed base 1 is placed within the range of the injection site, and the operator uses two fingers of the left hand to pass through the finger holes 211 of the pressing pieces 2 on both sides of the fixed base 1 and apply downward pressure. After being pressed, the pressing pieces 2 on both sides of the fixed base 1 will move downward and cooperate with the fixed base 1 to wrap and attach the patient's forearm. The lower surface of the fixed base 1 will also be tightly attached to the color number site under the action of pressure, providing a fixed basis for subsequent injection operations.

[0093] Before implementing step S100, the method further includes step S10:

[0094] Prepare for the injection procedure.

[0095] Specifically, the injection operation preparation includes determining the range of the injection site, selecting the syringe model, and adjusting the length adjustment member 322 and the width adjustment member 323 according to the selected syringe model so that the support assembly 32 can better adapt to the size of the syringe.

[0096] S200, adjusting the height of the angle adjustment component 33 so that the included angle between the supporting fixture 31 and the supporting component 32 is within the injection angle range.

[0097] Specifically, the clamping member 333 is rotated so that the clamping member 333 is located in the adjustment hole 3312, and then the height adjustment member 332 is moved up and down by the clamping member 333. Since one end of the height adjustment member 332 is in contact with the supporting component 32, the angle between the supporting component 32 and the supporting fixing member 31 changes during the up and down movement of the height adjustment member 332. During this process, the operator can always observe the angle observation member 334 to determine the current change in the angle between the supporting component 32 and the supporting fixing member 31. After the angle between the component 32 and the supporting fixing member 31 is adjusted to an appropriate angle range, stop moving the height adjustment member 332 up and down, then rotate the clamping member 333 to rotate it into the clamping hole 3313 corresponding to the current appropriate angle range, so as to fix the height of the angle adjustment component 33. Since the supporting component 32 abuts against the height adjustment member 332 due to gravity, the angle between the supporting component 32 and the supporting fixing member 31 will be fixed, which is convenient for the operator to place the syringe on the supporting component 32 for injection.

[0098] S300, placing the syringe on the supporting assembly 32, and performing the injection operation.

[0099] Specifically, after placing the syringe on the support assembly 32, the angle of the syringe relative to the middle and lower section of the outer side of the patient's forearm is the angle between the support assembly 32 and the support fixture 31. As a result, the operator can use the syringe to perform a stable injection operation at an adjusted angle under the stable support of the injection operation fixture.

[0100] In summary, an injection operation fixture comprises a fixed base member 1, a pressing member 2 and a supporting device 3. The fixed base member 1 is made of a bendable material and is used to be attached to the site to be injected; two pressing members 2 are provided, and the two pressing members 2 are respectively provided on both sides of the fixed base member 1, and a finger penetration hole 211 is provided on the pressing member 2; the supporting device 3 is provided on the fixed base member 1, and the supporting device 3 is inclined on the fixed base member 1, and the supporting device 3 is used to support the syringe.

[0101] When the operator uses the injection operation fixture, he places the fixed base member 1 on the patient's injection site, such as the arm, and then the operator inserts two fingers of one hand into the finger holes 211 on the pressing members 2 on both sides of the fixed base member 1, and applies pressure to the two pressing members 2 with two fingers. The fixed base member 1 can be bent and tightly attached to the patient's injection site. At this time, the other hand places the syringe against the supporting device 3. Since the supporting device 3 is tilted on the fixed base member 1, the needle of the syringe can be aligned with the injection site. After that, the medical staff can stably perform the injection operation with the hand that touches the syringe.

[0102] The patent application realizes two-handed operation through the injection operation fixture. One hand is responsible for the stability of the injection operation fixture, and the other hand is responsible for the injection operation. Compared with the single-handed operation in the prior art that needs to be responsible for both support and injection operations, the stability of the injection operation is greatly improved. At the same time, since the supporting device 3 is tilted on the fixed base 1, a stable tilt angle is provided for the operator. The operator only needs to place the syringe against the supporting device 3 to obtain a stable injection angle, which once again improves the stability of the injection operation and solves the problem of instability when the operator uses one-hand support to perform the injection operation.
