Description

Technical Field

[0001] The utility model relates to the technical field of auricular vein injection, and particularly relates to a mammalian auricular vein injection needle with a clamping function. Background Art

[0002] At present, in many fields such as medical experiments and veterinary clinics, it is often necessary to perform auricular vein injection operations on mammals. During the process of inserting the injection needle into the auricular vein blood vessel, usually, medical staff need to fix the mammal with one hand and hold the needle with the other hand for puncture. After the puncture is completed, usually, a clip is used to clamp the mammal and the injection needle to fix the injection needle on the mammal, thereby reducing the displacement risk of the injection needle and ensuring the accurate injection of the drug.

[0003] However, since the existing ordinary injection needles lack an auxiliary fixing structure specifically designed for the morphology of mammals, when fixing the injection needle on the mammal, an additional clamping device needs to be used. In this way, the inconvenience of fixing the injection needle is increased, which is not conducive to improving the working efficiency of the auricular vein injection operation on mammals.

[0004] Therefore, how to improve the convenience of fixing the injection needle to improve the working efficiency of the auricular vein injection operation on mammals is a technical problem that needs to be solved urgently at present. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a mammalian auricular vein injection needle with a clamping function to improve the convenience of fixing the injection needle and the working efficiency of the auricular vein injection operation on mammals, aiming at the problems of inconvenience in fixing the injection needle and being not conducive to improving the working efficiency of the auricular vein injection operation on mammals that occur during the auricular vein injection operation on mammals at present.

[0010] When the clamping assembly is in the first state, the pressing member is in an initial state, and the pressing member in the initial state applies pressure to the side wall of the injection needle body, so that the injection needle body is fixed relative to the groove;

[0011] When the clamping assembly is in the second state, the first airbag on the first grip is squeezed, so that the second airbag expands, and the second airbag pushes the pressing member to move, so as to reduce the pressure applied by the pressing member to the side wall of the injection needle body, so that the injection needle body can move relative to the groove along the length direction of the groove;

[0025] As a preferred technical solution of the present application, a plurality of anti-slip strips are provided on the first handle and / or the second handle, and the plurality of anti-slip strips are equally spaced;

[0026] The first airbag and the second airbag are connected through a first air pipe.

[0027] Compared with the prior art, the beneficial effects of the present utility model:

[0028] 1. In the solution of the present application, by providing a clamping assembly, the clamping assembly is matched with the injection needle body. When the clamping assembly is in the first state, the injection needle body is fixed relative to the groove. When the clamping assembly is in the second state, the injection needle body can move relative to the groove along the length direction of the groove. In this way, when the operator performs an auricular marginal vein injection operation on an animal, the operator can hold the clamping assembly by hand and first make the clamping assembly in the first state. In this state, since the injection needle body is fixed relative to the groove on the clamping assembly, when the clamping assembly in the first state is in an open state, the injection needle body can move together with the clamping assembly, so that it is convenient to control the movement of the injection needle body when the operator holds the clamping assembly by hand, so as to more accurately insert the injection needle body into the auricular marginal vein blood vessel of the animal; after the injection needle body is inserted into the preset position, the operator increases the holding force on the basis of continuously holding the clamping assembly by hand, so that the opening of the clamping assembly increases, and the clamping assembly changes from the first state to the second state, so as to reduce the pressure exerted by the pressing member on the side wall of the injection needle body, so that the injection needle body can move relative to the groove along the length direction of the groove. In this state, the clamping assembly can be moved relative to the injection needle body along the length direction of the groove, so as to adjust the position of the clamping assembly, and reduce the pulling on the injection needle body when adjusting the position of the clamping assembly, so as to ensure the stability of the insertion of the injection needle body while facilitating the selection of a suitable area on the animal's ear for the clamping assembly to clamp, and further improve the flexibility of the clamping assembly clamping on the animal's ear; after the clamping assembly moves to the preset position, then by reducing the holding force of holding the clamping assembly by hand, the clamping assembly is switched from the second state to the first state, so that the injection needle body is fixed relative to the clamping assembly, and the clamping assembly clamps on the animal's ear, so that the injection needle body can be firmly fixed on the animal's ear. In the whole process of insertion and fixation, only the state of the clamping assembly needs to be controlled. In this way, the convenience of fixing the injection needle body is improved, and the working efficiency of the operator performing an auricular marginal vein injection operation on a mammal can be improved; at the same time, before performing an auricular marginal vein injection operation, the clamping assembly can be first in the second state, so that the injection needle body moves along the length direction of the groove, so as to adjust the length of the injection needle body extending out of the clamping assembly, and then the clamping assembly is in the first state, so that the injection needle body is fixed relative to the clamping assembly, which is more conducive to the operator controlling the depth of the injection needle body inserted into the animal body during the subsequent injection;

[0029] 2. Further, by providing an elastic contact section, when the squeezing member applies pressure to the injection needle body, the contact section can have different deformation degrees, so as to facilitate adjusting the magnitude of the pressure applied by the squeezing member to the side wall of the injection needle body. When controlling the opening angle of the clamping assembly, the first airbag can have different squeezing degrees, thereby facilitating adjusting the magnitude of the pressure applied by the squeezing member to the side wall of the injection needle body. In this way, during the process of the injection needle body piercing into the marginal ear vein, the magnitude of the pressure applied by the squeezing member to the side wall of the injection needle body can be reduced. Thus, when there is a large resistance during the piercing process, the injection needle body can move relative to the groove, so as to slow down the piercing speed of the injection needle body when the piercing resistance is large. At the same time, during the piercing process, the operator can observe the relative position of the clamping assembly and the injection needle body, so as to judge the magnitude of the resistance received by the injection needle body during the piercing process based on the displacement amount of the injection needle body relative to the clamping assembly, so as to more clearly know the piercing condition of the injection needle body;

[0030] 3. Further, by providing a second handle, a second clamping plate and a torsion spring, when the operator holds the clamping assembly, by controlling the magnitude of the force when holding the clamping assembly, the deformation amount of the torsion spring can be changed, so as to change the angle between the first clamping plate and the second clamping plate, thereby facilitating the clamping assembly to be in the first state or the second state. Moreover, when the first handle rotates relative to the second handle, the squeezing degree when the first airbag is squeezed by the first handle and the second handle can be adjusted, so as to adjust the magnitude of the pressure applied by the squeezing member to the side wall of the injection needle body, thereby facilitating adjusting the relative position relationship between the injection needle body and the groove;

[0031] 4. Further, by providing a first base and a second base, when the first base rotates relative to the first handle body, the adjusting seat can move relative to the first handle body along its own height direction, thereby adjusting the distance between the first airbag and the first handle body, and further adjusting the opening angle of the clamping assembly when the first handle and the second handle cooperate to squeeze the first airbag. In this way, by adjusting the distance between the first airbag and the first handle body, the angle range between the first clamping plate and the second clamping plate on the clamping assembly in the first state can be controlled, and the angle range between the first clamping plate and the second clamping plate on the clamping assembly in the second state can be controlled, thereby improving the applicable range of the mammalian marginal ear vein injection needle of the present application and improving the convenience of performing marginal ear vein injection operations on animal ears of various different thicknesses.

[0045] Embodiment 1: A mammalian auricular vein injection needle with a clamping function provided in this embodiment is shown in Figures 1-7 the figure, including a clamping assembly 1 and an injection needle body 2. The clamping assembly 1 is used to clamp the animal's ear. The clamping assembly 1 includes a first pinch handle 3 and a first clamping plate 4;

[0046] A groove 5 and an extrusion member 6 are provided on the first clamping plate 4. The injection needle body 2 is stuck in the groove 5. The extrusion member 6 is movable relative to the first clamping plate 4. A first airbag 7 is provided on the first pinch handle 3. The extrusion member 6 is adapted to a second airbag 8. The first airbag 7 is communicated with the second airbag 8;

[0047] The clamping assembly 1 has a first state and a second state;

[0048] When the clamping assembly 1 is in the first state, the extrusion member 6 is in an initial state. The extrusion member 6 in the initial state applies pressure to the side wall of the injection needle body 2 to fix the injection needle body 2 relative to the groove 5;

[0049] When the clamping assembly 1 is in the second state, the first airbag 7 on the first grip 3 is squeezed, causing the second airbag 8 to expand. The second airbag 8 pushes against the extrusion member 6 to move, so as to reduce the pressure exerted by the extrusion member 6 on the side wall of the injection needle body 2, enabling the injection needle body 2 to move relative to the groove 5 along the length direction of the groove 5;

[0050] And when the clamping assembly 1 is in the first state, the clamping assembly 1 is in a clamping state or an open state.

[0051] In this application, by providing the clamping assembly 1, the clamping assembly 1 is matched with the injection needle body 2. When the clamping assembly 1 is in the first state, the injection needle body 2 is fixed relative to the groove 5. When the clamping assembly 1 is in the second state, the injection needle body 2 can move relative to the groove 5 along the length direction of the groove 5. Thus, when the operator performs an auricular marginal vein injection operation on an animal, the clamping assembly 1 can be held by hand, and the clamping assembly 1 is first set to the first state. In this state, since the injection needle body 2 is fixed relative to the groove 5 on the clamping assembly 1, when the clamping assembly 1 in the first state is in an open shape, the injection needle body 2 can move together with the clamping assembly 1, so that it is convenient to control the movement of the injection needle body 2 when the operator holds the clamping assembly 1 by hand, so as to more accurately insert the injection needle body 2 into the auricular marginal vein blood vessel of the animal. After the injection needle body 2 is inserted into the preset position, the operator increases the holding force on the basis of continuously holding the clamping assembly 1 by hand, increases the opening of the clamping assembly 1, and changes the clamping assembly 1 from the first state to the second state, so as to reduce the pressure exerted by the pressing member 6 on the side wall of the injection needle body 2, so that the injection needle body 2 can move relative to the groove 5 along the length direction of the groove 5. In this state, the clamping assembly 1 can be moved relative to the injection needle body 2 along the length direction of the groove 5 to adjust the position of the clamping assembly 1, and the pulling on the injection needle body 2 is reduced when adjusting the position of the clamping assembly 1, so as to ensure the stability of the insertion of the injection needle body 2 while facilitating the selection of a suitable area on the animal's ear for the clamping assembly 1 to clamp, and further improving the flexibility of the clamping assembly 1 when clamping on the animal's ear. After the clamping assembly 1 is moved to the preset position, then by reducing the holding force on the clamping assembly 1 held by hand, the clamping assembly 1 is switched from the second state to the first state, so that the injection needle body 2 is fixed relative to the clamping assembly 1, and the clamping assembly 1 clamps on the animal's ear, so that the injection needle body 2 can be firmly fixed on the animal's ear. During the whole process of insertion and fixation, only the state of the clamping assembly 1 needs to be controlled. Thus, the convenience of fixing the injection needle body 2 is improved, and the working efficiency of the operator for performing auricular marginal vein injection operations on mammals can be improved. At the same time, before performing the auricular marginal vein injection operation, the clamping assembly 1 can be first set to the second state to enable the injection needle body 2 to move along the length direction of the groove 5, so as to adjust the length of the injection needle body 2 extending out of the clamping assembly 1, and then the clamping assembly 1 is set to the first state to fix the injection needle body 2 relative to the clamping assembly 1, which is more conducive to the operator controlling the depth of insertion of the injection needle body 2 into the animal body during subsequent injections;

[0052] In this application, the opening of the clamping assembly 1 refers to the opening formed by the part of the clamping assembly for clamping the ear. On the basis that the clamping assembly is in the first state, after the operator holds the clamping assembly 1 by hand, the opening size of the clamping assembly 1 can be changed by controlling the clamping force, so that the clamping assembly 1 clamps or releases the clamping effect on the animal's ear.

[0053] As a preferred embodiment, on the basis of the above method, further, a first sliding groove 9 is provided on the first clamping plate 4, the pressing member 6 is located in the first sliding groove 9, a first spring 10 is provided in the first sliding groove 9, the first spring 10 has elasticity, one end of the first spring 10 abuts against the inner wall of the first sliding groove 9, and the other end abuts against the pressing member 6. When the clamping assembly 1 is in the first state, the first spring 10 provides an elastic force to keep the pressing member 6 in the initial state.

[0054] Further, by providing the first sliding groove 9, the movement of the pressing member 6 is restricted, so that the pressing member 6 can move along the length direction of the first sliding groove 9. At the same time, by providing the first spring 10, when the clamping assembly 1 is in the first state, the first spring 10 can provide an elastic force to keep the pressing member 6 in the initial state. In this way, the stability of the injection needle body 2 being fixed can be further improved.

[0055] As a preferred embodiment, on the basis of the above method, further, a first baffle 11 is further provided in the first sliding groove 9, a first accommodating area is formed between the first baffle 11 and the pressing member 6, and the second airbag 8 is located in the first accommodating area.

[0056] Further, by providing the first baffle 11, the second airbag 8 is located in the first accommodating area. When the clamping assembly 1 is in the first state, the first airbag 7 on the first grip 3 is in an uncompressed state. At this time, under the elastic force of the first spring 10, the second airbag 8 is in a deflated state, and the pressing member 6 applies pressure to the side wall of the injection needle body 2, so that the injection needle body 2 is fixed relative to the groove 5. During the process of the clamping assembly 1 changing from the first state to the second state, the first airbag 7 is squeezed, so that the gas in the first airbag 7 is transferred to the second airbag 8, and the gradually expanding second airbag 8 pushes the pressing member 6 to move, so that the pressure of the pressing member 6 on the side wall of the injection needle body 2 is reduced, and further the injection needle body 2 can move relative to the groove 5 along the length direction of the groove 5. In this way, the convenience of pushing the pressing member 6 is improved.

[0057] As a preferred embodiment, on the basis of the above method, further, a section of the pressing member 6 for contacting the injection needle body 2 is a contact section 12, and the contact section 12 has elasticity;

[0058] The contact section 12 is made of rubber material.

[0059] Furthermore, by providing an elastic contact section 12, when the extruding member 6 applies pressure to the sidewall of the injection needle body 2, the contact section 12 can have different degrees of deformation, thereby facilitating the adjustment of the pressure applied by the extruding member 6 to the sidewall of the injection needle body 2. When controlling the opening angle of the clamping assembly 1, the first airbag 7 can have different degrees of extrusion, further facilitating the adjustment of the pressure applied by the extruding member 6 to the sidewall of the injection needle body 2. In this way, during the process of the injection needle body 2 piercing into the marginal ear blood vessel, the magnitude of the pressure applied by the extruding member 6 to the sidewall of the injection needle body 2 can be reduced. When there is a situation where the resistance to the injection needle body 2 during piercing is relatively large, the injection needle body 2 can move relative to the groove 5, thereby slowing down the piercing speed of the injection needle body 2 when the piercing resistance is large. At the same time, during the piercing process, the operator can observe the relative position of the clamping assembly 1 and the injection needle body 2, so as to judge the magnitude of the resistance received by the injection needle body 2 during piercing based on the displacement amount of the injection needle body 2 relative to the clamping assembly 1, so as to more clearly know the piercing condition of the injection needle body 2.

[0060] As a preferred embodiment, on the basis of the above method, further, the injection needle body 2 includes a needle seat 13, a needle tip 14, and an infusion tube 15. One end of the needle seat 13 is connected to the needle tip 14, and the other end is connected to the infusion tube 15. The needle seat 13 on the injection needle body 2 is stuck in the groove 5.

[0061] Furthermore, by providing the needle seat 13, the needle seat 13 on the injection needle body 2 is stuck in the groove 5, so that the needle seat 13 is limited in the direction perpendicular to its length direction, thereby improving the firmness of the needle seat 13 stuck in the groove 5, and thus facilitating the formation of an integrated structure between the injection needle body 2 and the clamping assembly 1.

[0062] Embodiment 2: On the basis of the technical solution of Embodiment 1, further, referring to Figure 1 、 Figures 3-7 As shown, the clamping assembly 1 further includes a second grip 16 and a second clamping plate 17. The second grip 16 is connected to the second clamping plate 17, and the first grip 3 is rotatably connected to the second grip 16;

[0063] A torsion spring 18 is also fitted between the first grip 3 and the second grip 16. The torsion spring 18 provides an elastic force to keep the clamping assembly 1 in an initial state when there is no external force.

[0064] Further, by providing the second grip 16, the second clamping plate 17 and the torsion spring 18, when the operator holds the clamping assembly 1, by controlling the magnitude of the force when holding the clamping assembly 1, the deformation amount of the torsion spring 18 is changed, so as to change the angle between the first clamping plate 4 and the second clamping plate 17, thereby facilitating the clamping assembly 1 to be in the first state or the second state. Moreover, when the first grip 3 rotates relative to the second grip 16, the extrusion degree when the first airbag 7 is extruded by the first grip 3 and the second grip 16 can be adjusted, so as to adjust the magnitude of the pressure exerted by the extrusion member 6 on the side wall of the injection needle body 2, thereby facilitating the adjustment of the relative positional relationship between the injection needle body 2 and the groove 5.

[0065] As a preferred embodiment, on the basis of the above manner, further, the first grip 3 includes a first grip body 301 and an adjustment seat 302. The adjustment seat 302 includes a first base 303 and a second base 304. The first base 303 and the second base 304 are rotatably connected. The first base 303 is threadedly connected to the first grip body 301. The first airbag 7 is provided on the second base 304.

[0066] By rotating the first base 303 relative to the first grip body 301, the adjustment seat 302 moves relative to the first grip body 301 along its own height direction to adjust the distance between the first airbag 7 and the first grip body 301.

[0067] When the clamping assembly 1 changes from the first state to the second state, the first grip 3 and the second grip 16 cooperate to squeeze the first airbag 7, so that the gas in the first airbag 7 transfers to the second airbag 8.

[0068] Further, by providing the first base 303 and the second base 304, when the first base 303 rotates relative to the first grip body 301, the adjustment seat 302 can move relative to the first grip body 301 along its own height direction, thereby adjusting the distance between the first airbag 7 and the first grip body 301, and further adjusting the opening angle of the clamping assembly 1 when the first grip 3 and the second grip 16 cooperate to squeeze the first airbag 7. In this way, by adjusting the distance between the first airbag 7 and the first grip body 301, the angle range between the first clamping plate 4 and the second clamping plate 17 on the clamping assembly 1 in the first state can be controlled, and the angle range between the first clamping plate 4 and the second clamping plate 17 on the clamping assembly 1 in the second state can be controlled, thereby increasing the applicable range of the mammalian ear marginal vein injection needle of the present application and improving the convenience of performing ear marginal vein injection operations on the ears of various different thicknesses of animals.
