Description

Puncture needle fixing device

Technical Field

The utility model relates to the technical field of medical auxiliary instruments, in particular to a puncture needle fixing device.

Background

Puncturing blood vessels and tissues with a puncture needle is an important method for clinically treating and diagnosing diseases and obtaining samples of blood, tissues and the like of patients. When medical personnel use the pjncture needle to carry out the needle entering puncture, after the puncture gets into the ideal position, medical personnel need carry out operation next step, if connect operation such as sampling pipe. At this time, 2 problems may occur: first, when a patient with a low fitting degree is operated, the puncture needle is likely to be displaced if not fixed. Secondly, when the medical staff operates by a single person, the operations such as collecting samples need to be completed by two hands, and the puncture needle may be displaced and fall off at the moment. The shift of pjncture needle not only increases the risk of vascular injury, increases the probability of carrying out the secondary puncture to the patient simultaneously, increases medical staff's work load, influences the efficiency of medical treatment work. Meanwhile, the risk of needle head sliding is increased due to the displacement of the puncture needle, so that blood/tissue of a patient is in contact with the outside, and the risks of specimen pollution and infection and environmental pollution of outside personnel are increased. The fixing seat of the abdominal cavity puncture needle disclosed in the chinese patent CN206822646U limits the distance and angle of the abdominal cavity puncture needle by means of clamping the tail part of the puncture needle, and avoids the puncture from damaging the abdominal organs of the patient, but the fixing seat can only be applied to fixing of a certain puncture needle.

Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments and not all embodiments of the present application; and the structures shown in the drawings are merely schematic and do not represent actual objects. It should be noted that all other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the protection scope of the present application.

As shown in figures 1-2, the utility model provides a puncture needle fixing device which sequentially comprises a skin patch 1, a base 2 and a fixing layer 3 from bottom to top, wherein the base can be deformed. The skin patch 1, the base 2 and the fixing layer 3 are not connected together before use, and the base 2 is combined one by one after being plastic according to the shape of the puncture needle.

The patch 1 of the present invention is used to secure the device of the present invention to a patient. The skin patch disclosed by the utility model is preferably made of a skin-friendly material. The connection between the skin patch 1 and the base 2 according to the utility model can be realized in any way, as long as a firm connection is ensured. Preferably, the two surfaces of the skin patch 1 are both sticky, one surface is used for sticking the skin of a patient, and the other surface is used for sticking the deformed base 2.

The base 2 of the utility model can be deformed and can mould different shapes according to the shape of the puncture needle to be fixed, thereby realizing the fixation of various puncture needles and limiting the movement of the puncture needle. The base 2 and the fixing layer 3 according to the utility model can be connected in any way as long as a secure connection is ensured, for example a detachable connection or an adhesive connection. The base 2 of the present invention can be shaped into different three-dimensional shapes, such as rectangle, prism, pyramid, comb, wave, zigzag, etc., which are determined according to the shape of the fixed puncture needle, for example, the base 2 is shaped into a short comb to fix the venous blood collection needle, the base 2 is shaped into a high zigzag to fix the arterial puncture needle, and the base 2 is shaped into a rectangle to fix the chest puncture needle. The base 2 is preferably made of deformable rubber or deformable silica gel, and has certain hardness in addition to deformation, so that the base plays a supporting role.
