Description

Technical Field

[0001] This utility model relates to the field of injection auxiliary equipment technology, and in particular to a positioning fixture for fixing a syringe in the vertical direction. Background Technology

[0002] In existing laboratory preparation of blood culture bottles or other types of containers, gel-based culture material is injected into the container. This is usually done manually. The experimenter needs to hold and lift the syringe containing the culture material and insert it into the blood sample bottle for injection. The injection must ensure that the inner wall of the bottle is clean, so it is required to keep the sample outlet as vertical as possible.

[0003] The above process has the following problems in practical application: 1. The entire process requires a person to hold and lift the syringe containing the culture medium. When the preparation demand is large, even a 500ml syringe may be used. In addition to the nutrients, the overall weight is quite heavy. Whether holding and extracting or injecting, it is extremely time-consuming and laborious. 2. If the syringe itself is uneven near the needle tip, or if the needle tip has uneven inner wall thickness or an incorrect opening angle, even if the syringe is perpendicular to the bottle opening during injection, it doesn't guarantee perfectly vertical sample dispensing; the sample may be dispensed at an angle. In this case, the syringe needs to be tilted at a certain angle for adjustment. The experimenter needs to inject at a specific angle to maintain vertical dispensing as much as possible and avoid sample sticking to the bottle wall. However, in demanding experimental work, cumbersome procedures can easily lead to operational errors, affecting the tilt angle and causing sample sticking to the bottle wall, resulting in preparation failure. Utility Model Content

[0004] This utility model provides a positioning fixture for fixing a syringe vertically, aiming to solve the problems mentioned above, such as the need to hold and pull the syringe continuously during injection, which is time-consuming and laborious, and the need to maintain a certain angle for injection when there are errors in the syringe preparation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A positioning fixture for vertically fixing a syringe includes a receiving bracket placed on a workbench. The top of the receiving bracket is provided with a limiting groove. The syringe is embedded in the limiting groove and received on the receiving bracket, with the needle penetrating through the receiving bracket. The syringe is suspended above the workbench through the receiving bracket. The limiting groove surrounds the syringe, and several adjusting and fixing components are provided on the limiting groove around the shaft to form a limiting engagement with the syringe, which is used to adjust the tilt angle of the syringe; A limiting component is provided at the point where the needle protrudes from the receiving bracket. The limiting component is arranged around the needle and forms a limiting engagement with the needle. The needle passes through the limiting component and exits.

[0006] Preferably, the receiving bracket includes a horizontally arranged receiving plate, and several legs are welded and fixed around the outer side of the receiving plate, so that the receiving plate is suspended above the workbench surface by the legs.

[0007] Preferably, the support legs are at least three and are arranged at equal intervals around the central axis of the receiving plate.

[0008] Preferably, the bottom of each of the legs is provided with an anti-slip pad.

[0009] Preferably, the limiting groove includes an annular groove arranged concentrically and coaxially with the receiving bracket. The annular groove is welded and fixed to the top of the receiving bracket. Adjustment and fixing components are arranged at equal intervals around the axis on the annular groove. The annular groove between the adjustment and fixing components is provided with a hollowed-out viewing hole for observing the progress of the syringe in the annular groove.

[0010] Preferably, each of the adjusting and fixing components includes a nut welded to the inner wall of the limiting groove and a screw corresponding to the nut. One end of the screw is provided with a rotating cap, and the other end of the screw first passes through the limiting groove radially from the outside of the limiting groove, then forms a threaded engagement with the corresponding nut, and finally enters the limiting groove to form a limiting engagement with the syringe.

[0011] Preferably, the adjusting and fixing components are at least three and are arranged at equal intervals around the central axis of the limiting groove.

[0012] Preferably, the limiting component includes an outlet groove arranged concentrically and coaxially with the receiving bracket. Several elastic telescopic rods are arranged around the axis on the inner wall of the outlet groove. All elastic telescopic rods are arranged radially, and one end of the elastic telescopic rod is fixedly engaged with the inner wall of the outlet groove. The other end of the elastic telescopic rod is provided with a fixing block to form a limiting engagement with the needle.

[0013] Preferably, the elastic telescopic rods are at least three in number and are arranged at equal intervals around the central axis of the outlet groove.

[0014] Preferably, the fixing block is provided with an elastic pad on the side near the needle tip, and the fixing block forms a limiting fit with the needle tip through the elastic pad.

[0015] The beneficial effects of this utility model are: 1. With this device, the syringe can be suspended and fixed above the operating platform. The experimenter only needs to place the container under the needle and push the syringe plunger, avoiding continuous holding, improving injection efficiency and reducing manual operation. 2. By adjusting the fixing component, the syringe can be fixed and held at a certain tilt angle, so that subsequent injections can be performed at this angle. Initially, adjust the angle according to the syringe to ensure vertical discharge. After fixing at this angle, you only need to place a container under the syringe. 3. The syringe barrel is not completely straight at the end near the needle tip. This device can still ensure stability and can be adjusted for syringe barrels of different sizes, greatly improving the applicability of the device. 4. Simple operation, easy installation, and low cost; 5. The limiting component provides a reaction force to limit the needle, thereby improving the overall stability of the syringe's limiting and fixing. Attached Figure Description

[0017] The embodiments will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-7 As shown in the preferred embodiment 1, the positioning fixture for fixing the syringe vertically includes a receiving bracket 1 placed on the workbench. The top of the receiving bracket 1 is provided with a limiting groove 2. The syringe 5 is embedded in the limiting groove 2 and received on the receiving bracket 1, and the needle tip passes through the receiving bracket 1. The syringe 5 is suspended above the workbench through the receiving bracket 1. The limiting groove 2 surrounds the syringe 5, and the limiting groove 2 is provided with several adjusting and fixing components 3 around the shaft to form a limiting fit with the syringe 5, which is used to adjust the tilt angle of the syringe 5. A limiting component 4 is provided at the point where the needle protrudes from the receiving bracket 1. The limiting component 4 is arranged around the needle and forms a limiting engagement with the needle. The needle passes through the limiting component 4 and exits.

[0019] In use, first test the syringe 5 containing culture material on the device. By adjusting the length of the adjusting fixing component 3, change the tilt angle of the syringe 5 in the limiting groove 2 until the material output of the syringe 5 is kept vertically downward. Fix the length of each part of the adjusting fixing component 3 to clamp the syringe 5 and fix it at the tilt angle. The needle passes through the limiting component 4 and elastically limits the limiting component 4 to maintain the overall stability of the syringe 5. Fill syringe 5 with culture medium, insert each container under the needle, and push the plunger to inject the culture.

[0020] As a preferred embodiment 2, the receiving bracket 1 includes a horizontally arranged receiving plate 101. Several support legs 102 are welded and fixed around the outer side of the receiving plate 101. The receiving plate 101 is suspended above the workbench surface by the support legs 102 to ensure suspended installation for suspended injection.

[0021] Preferably, the suspended space can even accommodate an electronic balance, thereby controlling the quality of the injected culture material.

[0022] The outriggers 102 are at least three in number and are arranged at equal intervals around the central axis of the receiving plate 101 to ensure stability under stress.

[0023] The limiting groove 2 includes an annular groove 201 arranged concentrically and coaxially with the receiving bracket 1. The annular groove 201 is welded and fixed to the top of the receiving bracket 1. The adjusting and fixing components 3 are arranged at equal intervals around the axis on the annular groove 201. The annular groove 201 between the adjusting and fixing components 3 is provided with a hollowed-out viewing hole 202 for observing the progress of the syringe 5 in the annular groove 201.

[0024] In order to facilitate the fitting of the annular groove 201 with the syringe 5, its inner diameter is larger than the outer diameter of the syringe 5, which makes it easier to insert the syringe 5. By changing the length of each adjusting and fixing component 3 in the annular groove 201, the syringe 5 can be tilted toward the side with the shorter adjusting and fixing component 3.

[0025] Each of the adjustment and fixing components 3 includes a nut 301 welded to the inner wall of the limiting groove 2 and a screw 302 corresponding to the nut 301. One end of the screw 302 is provided with a rotating cap 303. The other end of the screw 302 first passes through the limiting groove 2 radially from the outside of the limiting groove 2, then forms a threaded engagement with the corresponding nut 301, and finally enters the limiting groove 2 to form a limiting engagement with the syringe 5.

[0026] The length of the screw 302 in the annular groove 201 can be adjusted by rotating the cap 303. This ensures that the syringes 5 of various sizes can be fixed, and the tilt angle of the syringes 5 can be adjusted by the different lengths of each screw 302. The screw 302 is threaded with the nut 301 to ensure that the length can be adjusted while also ensuring that the length is locked.

[0027] The adjusting and fixing components 3 are at least three in number and arranged at equal intervals around the central axis of the limiting groove 2. This facilitates adjustment of the tilt angle and at least ensures stability under force when tilted.

[0028] The limiting component 4 includes an outlet groove 404 arranged concentrically and coaxially with the receiving bracket 1. Several elastic telescopic rods 401 are arranged around the axis on the inner wall of the outlet groove 404. All elastic telescopic rods 401 are arranged radially, with one end of each rod fixedly engaged with the inner wall of the outlet groove 404, and the other end of each rod having a fixing block 402 that forms a limiting engagement with the needle. The elastic telescopic rods 401 provide a radial reaction force to press the needle, thereby cooperating with the adjusting and fixing component 3. The adjusting and fixing component 3 fixes the syringe body, and the limiting component 4 fixes the needle, improving the overall stability of the syringe 5.

[0029] The elastic telescopic rods 401 are at least three in number and are arranged at equal intervals around the central axis of the outlet groove 404 to ensure stability.

[0030] The fixing block 402 has an elastic pad 403 on the side near the needle tip. The fixing block 402 and the needle tip form a limiting engagement through the elastic pad 403, thus creating a buffer and preventing damage to the needle tip.

[0031] In a preferred embodiment 3, the bottom of each of the support legs 102 is provided with an anti-slip pad 6 to ensure the overall stability of the device.

[0032] As a preferred embodiment 4, the device can be used for culture medium injection into blood sample bottles.

[0033] As a preferred embodiment 5, the device can be used for hospital procedures such as feeding liquid food or gastric lavage, and it is convenient to fix the syringe 5.

[0034] The working principle of this utility model: In use, first test the syringe 5 containing culture material on the device. By adjusting the length of the adjusting fixing component 3, change the tilt angle of the syringe 5 in the limiting groove 2 until the material output of the syringe 5 is kept vertically downward. Fix the length of each part of the adjusting fixing component 3 to clamp the syringe 5 and fix it at the tilt angle. The needle passes through the limiting component 4 and elastically limits the limiting component 4 to maintain the overall stability of the syringe 5. Fill syringe 5 with culture medium, insert each container under the needle, and push the plunger to inject the culture.
