Description

Technical Field

[0001] The utility model belongs to the technical field of micro-pump medication, and in particular relates to a syringe with a fluorescent scale. Background Art

[0002] 50ml light-proof syringes are widely used for drugs that require light-proof micropump infusion, such as nitroglycerin injection, a common clinical drug for dilating coronary arteries, and nimodipine, a drug for brain surgery. The use of light-proof syringes can prevent light from decomposing drugs, thereby ensuring drug efficacy and patient safety. In clinical nursing work, it is necessary to record the speed and remaining amount of micropump drugs every hour. However, since the syringe of the light-proof syringe is dark in color, the color contrast with the black scale line and numbers is small, and it is not easy to observe the remaining amount. In addition, the piston head is black, which causes the scale to overlap with the remaining amount, making it more difficult to check. Therefore, some nurses in the clinic will use a flashlight to illuminate in order to check the remaining amount. However, this undoubtedly increases the risk of drug decomposition by light, because the light-proof syringe is not 100% light-proof, and its light-proof is only relative. Short-distance strong light irradiation can still allow light to penetrate the light-proof syringe directly to the drug, causing drug decomposition. Utility Model Content

[0003] The utility model aims to provide a syringe with a fluorescent scale, which is provided with a fluorescent scale, so that the staff can read the reading conveniently. At the same time, the remaining amount of the liquid medicine can be obtained by reading the indicating scale on the push rod, so that the overall reading is simpler.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A syringe with a fluorescent scale comprises an outer syringe barrel, a piston and a push rod and an inner sleeve, wherein the inner sleeve is sleeved in the outer syringe barrel and is provided with a fluorescent scale; the push rod and the piston are fixed, and the push rod is provided with an indicating scale, when the end of the piston corresponds to the top scale of the outer syringe barrel, the maximum value of the indicating scale corresponds horizontally to the top of the outer syringe barrel.

[0006] Advantages of setting between outer syringe and inner sleeve:

[0007] The outer syringe and the inner sleeve are connected in a sleeve-like manner, wherein a fluorescent scale is provided on the outer wall of the inner sleeve, which can emit light in a light-proof environment. Since the outer syringe is made of a transparent material, when the inner sleeve is sleeved in the outer syringe, the staff can read the fluorescent scale and avoid getting fluorescent reagents on their hands to ensure safety.

[0008] Coordinate reading between indicator scale and fluorescence scale:

[0009] When the maximum value of the indicating scale corresponds to the top level of the outer syringe, the piston is aligned with the fluorescent scale set on the outer wall of the inner sleeve. This allows the staff to read the distance the push rod moves forward from the fluorescent scale when pushing the liquid with the micro pump, and can also be read from the indicating scale on the push rod. For example, the push rod moves forward a distance of 10ml (the total capacity is 50ml). The staff can read it from the fluorescent scale set on the inner sleeve (the overlap and intersection of the bottom end of the piston and the fluorescent scale indicates 40ml), or read it from the push rod (at this time, the overlap and intersection of the push rod and the upper end of the outer syringe is 40ml. This greatly facilitates the staff to observe the remaining amount of the micro pump.

[0010] Preferably, the syringe further comprises a sealing ring, the top end of the inner sleeve is provided with an embedding groove, the sealing ring is embedded in the embedding groove, one side of the sealing ring is tightly pressed against the embedding groove, and the other side is tightly pressed against the inner wall of the outer syringe.

[0011] The role of the sealing ring:

[0012] The sealing ring is embedded in the embedded groove to prevent liquid from flowing into the gap between the outer syringe and the inner sleeve, thereby causing the scale of the fluorescent reagent to be deformed and blurred. At the same time, since the sealing ring is clamped to the inner wall of the outer syringe, it also plays a fixing role to prevent a small movement between the outer syringe and the inner sleeve.

[0013] Preferably, a needle connector is provided at the bottom end of the inner sleeve, and a through hole adapted for the needle connector to pass through is provided at the bottom end of the outer syringe.

[0014] Preferably, a positioning groove is provided at the inner bottom end of the outer injection cylinder, and correspondingly, an annular positioning protrusion adapted to the positioning groove is provided at the bottom end of the inner sleeve.

[0015] The annular positioning protrusion is matched with the positioning groove, thereby realizing the positioning of the outer injection cylinder and the inner sleeve.

[0016] Preferably, a needle is connected to the lower end of the needle connector.

[0017] Preferably, a force-applying push handle is provided at one end of the push rod facing away from the piston.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. By setting a fluorescent scale on the outer wall of the inner sleeve and sleeved in an outer syringe made of a transparent material, the staff can read the liquid level scale more easily in a light-proof environment without the need for lighting operations.

[0020] 2. By moving the push rod a specific distance, the indicating scale and the fluorescent scale on the inner sleeve move the same distance at the same time, thereby assisting the staff to read the micro pump residual from the scale on the push rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example

[0028] Based on the above description, this embodiment further supplements the syringe:

[0029] A syringe with fluorescent scale, the main body of which comprises:

[0030] External syringe 5;

[0031] Piston 4;

[0032] Putt 2;

[0033] Inner sleeve 6;

[0034] Sealing ring 3.

[0035] like Figure 3 and Figure 4 As shown, the scale on the inner sleeve 6 is 50ml-0ml from top to bottom. The scale on the push rod is 0ml-50ml from top to bottom. In the initial position, the plane where the lowest end of the piston 4 is located is flush with the plane where the 50ml scale line at the upper end of the inner sleeve 6 is located. At the same time, the scale 50ml on the push rod is flush with the plane where the top end of the outer syringe is located.

[0036] In this embodiment, for example, if the total dosage is 10 ml, the staff can read the dosage in the following two ways in a light-proof environment:

[0037] 1. Read the fluorescence scale on the outer wall of the inner sleeve 6, move the piston to 40ml, and in a light-proof environment, obtain the dosage of 10ml through the fluorescence scale. The outer syringe 5 and the inner sleeve 6 are made of gray light-shielding material.

[0038] 2. The push rod 2 moves downward a distance of 10 ml, and the plane where the 40 ml scale line of the push rod is located is flush with the plane where the top of the outer syringe 5 is located. Therefore, the staff can also infer that the dosage is 10 ml by reading the scale value 40 ml on the push rod.
