A new type of scalp acupuncture device

technical field

The utility model belongs to the field of medical surgical instruments, in particular to a novel scalp needle device.

Background technique

Scalp needles, also called venous needles, are mainly used clinically as needles for intravenous infusion, blood transfusion or blood collection. Taking blood collection as an example, during operation, medical staff generally complete the puncture with both hands first, then press the needle wing with one hand, and at the same time operate the blood collection test tube with the other hand and connect it to the end of the scalp needle to complete the blood collection. For some patients who can cooperate with medical staff voluntarily, the blood collection process can be relatively smooth; but for some patients who cannot cooperate with medical staff independently (such as children or some people without civil capacity, etc.), due to The needle of the scalp needle is exposed, and a person is often unable to complete the blood collection smoothly, and during the blood collection process, there may be a missed needle due to the patient's uncooperation, which may lead to blood collection failure.

Utility model content

In order to solve the above-mentioned shortcomings in the prior art, the present utility model provides a novel scalp acupuncture device that avoids the exposure of scalp needles, is simple to operate, and reduces the occurrence of missed needles. The specific scheme is as follows:

A novel scalp needle device comprises a scalp needle with a blood vessel and a connecting plate for temporarily fixing the scalp needle on the scalp, the top surface of the connecting plate is formed into an inclined surface, and the lower end of the connecting plate is provided with A puncture hole; the bottom surface of the connecting plate is provided with a first adhesive layer, and the top surface of the connecting plate is provided with a second adhesive layer.

Further, the length of the connecting plate is greater than the length of the scalp needle handle.

Further, a number of pipe grooves are provided on the top surface of the connecting plate near the higher end, and the depth of the pipe grooves is greater than the diameter of the blood vessel.

Further, the center of the top surface of the connecting plate is formed as a concave surface, and the top surface and the two side surfaces of the connecting plate are both chamfered.

Further, the connecting plate is made of flexible medical material.

The novel scalp needle device proposed by the utility model can realize the stability of the scalp needle after the scalp needle is taken off the hand, so that the medical staff can temporarily ignore the needle of the scalp needle after the successful puncture, and only operate the end of the blood vessel to complete the intravenous infusion, blood transfusion or blood collection That is, the structure is simple and the operation is convenient, which is especially suitable for patients who cannot cooperate with medical staff independently, and can also reduce the occurrence of missed needles.

Detailed ways

In order to describe the technical content, structural features, achieved objects and effects of the present invention in detail, the following examples are given and described in detail with the accompanying drawings.

As shown in FIG. 1 and FIG. 2 , a new type of scalp needle device, a new type of scalp needle device, and a new type of scalp needle device disclosed in the present invention include a scalp needle 20 with a blood vessel 10 and a scalp needle 20 The connecting plate 30 temporarily fixed on the scalp, the top surface of the connecting plate 30 is formed into a slope, the lower end of the connecting plate 30 is provided with a puncture hole 31; the bottom surface of the connecting plate 30 is provided with a first adhesive layer 32, the connecting plate A second adhesive layer 33 is provided on the top surface of 30 .

The use of a connecting plate with a beveled top surface and an adhesive layer on both sides can ensure that the puncture needle can be temporarily fixed on the patient's scalp at a certain angle after the needle tip is punctured, so that the medical staff can temporarily not need to puncture the patient behind it. Take the vessel end connector for operation.

The puncture hole is convenient to locate the puncture position of the patient. The first adhesive layer is used to fix the connecting plate on the patient's scalp, and the second adhesive layer is used to fix the scalp needle on the connecting plate, which is convenient for medical staff to operate and remove. end of blood vessels.

The length of the connecting plate 30 is greater than the length of the needle handle of the scalp needle 20 to ensure that the scalp needle can be stably fixed on the connecting plate.

As shown in Figure 3, the top surface of the connecting plate 30 is provided with a number of pipe grooves 34 at the position close to the higher end. The depth of the pipe grooves 34 is greater than the pipe diameter of the blood vessel 10. During use, the blood vessel is taken and placed in the pipe groove to ensure that the blood vessel is taken. position stability. The center of the top surface of the connecting plate 30 is formed into a concave surface. After the scalp needle is placed on the concave surface of the top surface of the connecting plate, it can be further fixed by applying medical tape outside. Stability between the medical tape and the connecting board.

The connecting plate 30 is made of flexible medical materials, such as medical silicone, on the one hand, the components of the scalp needle can be well attached to the connecting plate, and on the other hand, it can prevent the hard connecting plate from being connected to the patient's scalp. resulting discomfort.

The working process of the present utility model is as follows:

First, select the puncture site according to the actual situation of the patient, and use the first adhesive layer to temporarily fix the connecting plate on the patient's scalp (align the puncture hole with the puncture site); then operate the scalp needle for puncture, and remove the needle after successful puncture core and directly press the scalp needle handle to the top surface of the connecting plate (medical tape can be used to further fix the scalp needle); at this time, the scalp needle can be temporarily ignored, and the interface that takes the end of the blood vessel can be operated according to the actual treatment needs (operable with both hands). , and if necessary, one of the hands can be used to limit the movements of some special patients to further ensure the smooth progress of the blood collection process), and operations such as intravenous infusion, blood transfusion or blood collection can be performed.

In addition, after the puncture is successful, in order to avoid the exposure of the puncture site, a piece of medical tape may be pasted outside the puncture hole to cover it.

As shown in Fig. 4, in another specific embodiment, the connecting plate can adopt a two-section split design, that is, a breakable connection is used between the part with the puncture hole and the part with the second adhesive layer (for example, this The two pieces are connected by connecting piece 4).

When pulling out the scalp needle, first use scissors to cut the connecting piece, then tear off the connection between the connecting plate and the first adhesive layer of the patient's scalp, and then hold the latter part of the connecting plate to connect the scalp needle and pull out the needle together. Only part of the connecting plate surrounding the puncture site is left on the patient's scalp. Just put an alcohol cotton in the puncture hole of the connecting plate, and then stick a piece of medical tape on the outside. It is not necessary to press the needle hole all the time to stop bleeding; After a period of time when the bleeding stops, just tear off the remaining connecting plates and throw away the alcohol cotton directly, which is convenient and practical.

To sum up, it is only a preferred embodiment of the present utility model, and does not limit the protection scope of the present utility model. All equivalent changes and modifications made according to the scope of the utility model patent and the contents of the description are all covered by the utility model patent. within the range.
