Description

Technical Field

[0001] The present invention belongs to the technical field of nursing equipment, and particularly relates to a portable vasoconstrictor. Background Art

[0002] When the body is struck, local tissues are impacted by external forces, causing capillaries to rupture. Blood seeps from the ruptured blood vessels into the surrounding tissues, forming ecchymosis and swelling. After injury, the body initiates an inflammatory response. Inflammatory cells gather at the injured site and release inflammatory mediators. These substances cause blood vessels to dilate, increase vascular permeability, and lead to more fluid exuding into the tissue space, further exacerbating the swelling. Burns are caused by thermal damage to tissues. Heat causes tissue proteins to denature and cell structures to be damaged, resulting in the exudation of intracellular fluid. At the same time, external heat stimulation causes local blood vessels to dilate, and at this time, a large amount of liquid components in the blood exude into the tissue space, forming edema. Similar to a knock injury, burns also trigger an inflammatory response. The release of inflammatory mediators causes blood vessels to dilate further, increasing exudation and resulting in swelling;

[0003] An effective method for dealing with skin swelling is generally cold compress. However, existing cooling and cold compress devices are generally large in size and cannot be carried around, resulting in the inability of medical staff to perform cold compress treatment on the patient's affected area immediately upon arrival at the scene, making them inconvenient to use.

[0004] Therefore, those skilled in the art have proposed a portable vasoconstrictor to solve the problems raised in the background art.

[0005] The above information disclosed in this background art is only used to enhance the understanding of the background art of the present invention. Therefore, it may include prior art that is not known to ordinary skilled persons in this field. Summary of the Invention

[0006] The purpose of the present invention is to provide a portable vasoconstrictor to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A portable vasoconstrictor, comprising:

[0009] An installation mechanism, the installation mechanism includes an instrument end and an instrument housing. The instrument housing is fixedly arranged on the upper surface of the instrument end, and the instrument housing is of a cylindrical structure;

[0010] Cold compress mechanism, the cold compress mechanism includes a heat conduction chip assembly fixedly installed on the instrument end and a heat dissipation assembly arranged on the heat conduction chip assembly. The heat dissipation assembly includes an installation outer frame and a fan arranged on the installation outer frame. Both the heat conduction chip assembly and the heat dissipation assembly are located inside the instrument housing.

[0011] Preferably, threaded holes are provided on both the installation outer frame and the heat conduction chip assembly, and screws are screwed into the threaded holes. The installation outer frame is fixedly connected to the heat conduction chip assembly through the screws.

[0012] Preferably, a plurality of air outlet slots are provided on the circumferential side surface of the instrument housing, and the air outlet slots penetrate through the instrument housing.

[0013] Preferably, a lithium battery is arranged inside the instrument housing, and both the fan and the heat conduction chip assembly are electrically connected to the lithium battery.

[0014] Preferably, a power interface is provided on the upper surface of the lithium battery, and the power interface is electrically connected to the lithium battery.

[0015] Preferably, an interface slot is provided at one end of the instrument housing away from the instrument end, and the position and shape of the interface slot are adapted to the power interface.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The present invention arranges a small cylindrical instrument housing, and a heat conduction chip assembly and a heat dissipation assembly are carried inside the instrument housing. The heat conduction chip assembly uses materials with high thermal conductivity such as copper, aluminum, and graphene as heat sinks or heat pipes to quickly conduct the heat generated by the chip to the instrument end. The instrument end directly contacts the wound of the patient, so as to be able to perform temporary and rapid cold compress on the affected area of the patient. The low temperature will cause the blood vessels at the injured part to contract, reducing the blood flow, which can reduce the permeability of the blood vessels and reduce the exudation of liquid and cell components in the blood into the tissue space, thereby reducing swelling. And cold compress can reduce the sensitivity of nerve endings, relieve pain. At the same time, the lower temperature will also inhibit the metabolic rate of local tissues and reduce the accumulation of waste generated by metabolism, further reducing the inflammatory reaction. This device is small in size, low in cost and has a good effect of cooling and cold compress, and is more convenient to use, improving the on-site rescue efficiency of bruises and burns.

[0018] (2) The present invention arranges a lithium battery as the power supply source for the heat conduction chip assembly and the fan in this device. When the power is used up, it can be charged through the power interface and can be reused.

[0019] The above summary is for the purpose of the specification only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent by reference to the drawings and the following detailed description.
