[0002] In the field of modern medicine, internal jugular vein puncture is a common and important medical procedure, widely used in various situations that require rapid establishment of intravenous access, such as emergency treatment of patients with severe dehydration or shock, long-term intravenous infusion therapy, and hemodialysis. Internal jugular vein puncture requires the use of a puncture needle.

[0003] Currently, an existing puncture needle (such as patent number: CN219126591U) discloses a puncture needle comprising a needle tip, a needle shaft, and a needle tail connected in sequence. The needle tip and needle shaft are integrated into a single structure. On the needle shaft, a scale marking line is provided starting 1 cm from the tip of the needle tip. The needle tail is a straight structure with openings at both ends. The puncture needle provided by this utility model has a wide range of applications, is easy to operate, has high precision, and high visibility under ultrasound guidance, making it very suitable for widespread use.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: The existing device uses a traditional scale representation, that is, a series of scale lines are engraved on the needle bar, and then numbers are written on them in sequence to remind the operator of the insertion depth of the needle bar. However, because the needle bar is very thin, the scale lines and scale numbers engraved on it can only be set to a small size due to the thinness of the needle bar, making it difficult for the operator to see the scale lines and scale numbers clearly, thus making it difficult for the operator to judge the insertion depth of the needle bar. Summary of the Invention

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a graduated internal cervical puncture needle.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a graduated internal cervical puncture needle, including a sampling head, a needle rod fixedly connected to the sampling head, a needle tip section provided at the end of the needle rod away from the sampling head, the needle tip section being 1 cm long, the needle rod including a first segment, a second segment and a third segment, both the first segment and the second segment being provided with a first identification element and a second identification element, the first segment being close to the needle tip section, the first segment, the second segment and the third segment being alternately arranged, the first segment, the second segment and the third segment being arranged in six cycles, the first segment close to the needle tip section being the starting point of the first cycle, the second segment being set after the first segment, the third segment being set after the second segment, and the first segment of the second cycle being set after the third segment, the first segment, the second segment and the third segment being different colors.

[0026] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0027] Example: A graduated internal jugular puncture needle, such as Figures 1-10 As shown, it includes a sampling head 1, which is fixedly connected to a needle bar 8. The end of the needle bar 8 away from the sampling head 1 is provided with a needle tip 5, which is 1 cm long. The needle bar 8 includes a first segment 2, a second segment 3, and a third segment 4. The first segment 2 and the second segment 3 are both provided with a first identification element 6 and a second identification element 7. The first segment 2 is close to the needle tip 5. The first segment 2, the second segment 3, and the third segment 4 are arranged alternately. The first segment 2, the second segment 3, and the third segment 4 are arranged in six cycles. The first segment 2, which is close to the needle tip 5, is the starting point of the first cycle. The second segment 3 is set after the first segment 2, the third segment 4 is set after the second segment 3, and the first segment 2 of the second cycle is set after the third segment 4. The first segment 2, the second segment 3, and the third segment 4 are different colors.

[0028] The first segment 2 near the tip 5 is provided with a ring of first identification element 6, the first segment 2 in the second cycle is provided with two rings of first identification element 6, the first segment 2 in the third cycle is provided with three rings of first identification element 6, and the first segment 2 in the fourth cycle is provided with four rings of first identification element 6.

[0029] In the first cycle, the second segment 3 has one ring of the first identification element 6; in the second cycle, the second segment 3 has two rings of the first identification element 6; in the third cycle, the second segment 3 has three rings of the first identification element 6; and in the fourth cycle, the second segment 3 has four rings of the first identification element 6.

[0030] In the fifth cycle, the first segment 2 is equipped with one ring of second identification element 7, and in the sixth cycle, the first segment 2 is equipped with two rings of second identification element 7.

[0031] In the fifth cycle, the second segment 3 is equipped with one ring of second identification element 7, and in the sixth cycle, the second segment 3 is equipped with two rings of second identification element 7.

[0032] The lengths of the first segment 2, the second segment 3, and the third segment 4 are all 1 cm.

[0033] This application, by setting a first segment 2, a second segment 3, and a third segment 4, can determine the insertion depth based on the first segment 2, the second segment 3, or the third segment 4 in contact with the patient's skin surface, in conjunction with the first identification element 6 and the second identification element 7. By setting the first segment 2, the second segment 3, and the third segment 4 to different colors, this application makes it easier for operators to identify, solving the problem that existing devices make it difficult for operators to judge the insertion depth of the needle bar 8.

[0034] The principle of this utility model:

[0035] When performing a puncture using this application, the needle tip 5 of the needle shaft 8 is inserted into the patient's wound. After the needle shaft 8 is inserted into the patient's wound, the insertion depth can be determined based on the first segment 2, the second segment 3, or the third segment 4 that is in contact with the patient's skin surface. For example, when the operator observes that the first segment 2 is in contact with the patient's skin surface and that the first segment 2 is provided with three first identification elements 6, it can be concluded that the entire needle shaft 8 has penetrated into the patient's body for two cycles. Since the lengths of the first segment 2, the second segment 3, and the third segment 4 are all 1 cm, two cycles is 6 cm. Adding the length of the needle tip 5 itself, it can be concluded that the entire needle shaft 8 has penetrated into the patient's body for 7 cm. By setting the first segment 2, the second segment 3, and the third segment 4 to different colors, it is easier for the operator to identify them. Providing the first identification elements 6 and the second identification elements 7 on the first segment 2, the second segment 3, and the third segment 4 makes it easier for the operator to determine how many cycles of the first segment 2, the second segment 3, and the third segment 4 have been inserted, preventing the operator from forgetting how many cycles have been inserted due to inattention.

[0036] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
