Abstract

Disclosed is an electrothermal needle which belongs to an improvement for the prior art. A piece of purpose-made heating cord is arranged on the needle tip of a needle body front part, clinging to the needle body, a temperature measuring element is fixedly arranged near the heating cord, both the heating cord and the temperature measuring element are provided with conducting wire which is connected from the tail of the needle body, and the needle tip position is sealed with metal. The utility model has the advantages of capability of heating, temperature measuring, and temperature controlling, long service life, favorable reliability, etc.

Description

Heating needle

The utility model relates to a kind of improvement of moxibustion with electric warming needles, particularly a kind of moxibustion with electric warming needles that utilizes the energising heating to apply acupuncture.

Moxibustion with electric warming needles is exactly pin to be treated with thermotherapy combine the acupuncture treatment device for the treatment of, the early stage moxibustion with electric warming needles that uses is only at the back end burning Folium Artemisiae Argyi of acupuncture needle, by needle body the heat of rear end is reached anterior acupuncture position to obtain thermotherapy effect, but because the heat-transfer effect of needle body is poor, the intensification at the anterior acupuncture of needle body position is limited, therefore the thermotherapy effect of in fact this easy thermotherapy pin is very undesirable, and uses operation also pretty troublesome.Be the existence that addresses the above problem, now existing a kind of heater directly is arranged at the intravital moxibustion with electric warming needles of pin, its formation is inner wire and the needle tip face seal welding that coats with a tape insulation that inserts in this needle tubing, when electric current flows through the formed big resistance of needle point weld, this place just is in resistance heating, because heat generating spot is directly at the needle point place, do not exist the conduction decay to wait restriction, make the temperature at position that needle point stings to rise very highly, but the mode of heating of this moxibustion with electric warming needles mainly is to utilize the formed resistance of welding of inner wire and needle point end face to generate heat, this pad resistance comes off because of situations such as temperature rises repeatedly easily, influence service life and effect, and this moxibustion with electric warming needles can only heat and not have thermometric and temperature control, thereby also have influence on the effect of use widely, increased the unreliability of using, same to using and operating and bring certain trouble.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and provide a kind of can thermometric and long service life, functional reliability is good, uses easy to operate moxibustion with electric warming needles.

The purpose of this utility model is come real finishing by following technical solution, outside adherent being mounted with in the needle point place of needle body, be coated with the heating wire of heat-resistant insulation material, adjacent at heating wire is mounted with a temperature element, both all pick out from the needle body afterbody with lead, seal with metal in the front portion of needle body.

This utility model is directly welded in the needle point place with an end of heating wire, and lead is drawn from the other end and the needle body afterbody of heating wire respectively.

This utility model also is provided with joint sleeve at the afterbody of needle body, and two strands of external cables pass and respectively be connected to two connection-pegs from joint sleeve respectively.

This utility model adopts the PN junction critesistor as above-mentioned temperature element.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a needle body internal structure sketch map of the present utility model.

Below will the utility model is further introduced by accompanying drawing, it is needle body 1 that this utility model adopts the hollow stainless pin of external diameter φ 1.2mm, adherent being mounted with by metal material in the forward tip position of needle body 1 draws the heating wire 2 that forms, is coated with heat-resistant insulation material outward, by directly generating heat after heating wire 2 energisings and transferring heat on the needle body 1.One end of above-mentioned heating wire 2 can directly weld with needle body 1 forward needle point wall mutually, and the afterbody of the other end and needle body is drawn with lead 3 respectively, connects outside low-tension supply.Because this utility model is to utilize heating wire 2 directly to generate heat, therefore also can directly draw from the afterbody of needle body 1 at heating wire 2 its two ends of adherent arrangement back with lead 3.Also be mounted with the temperature element 4 of a miniature PN junction critesistor at heating wire 2 adjacents, it is fixed near the needle point position, also can adherently fix, and draws from the afterbody of needle body 1 with lead 5.Seal with metal 6 at the needle point position at last, can further heating wire 2 and temperature element 4 be fixed in the needle body 1 like this.The afterbody of needle body 1 is fixed with joint sleeve 7, and the power lead 3 of heating wire 2 and the lead 5 of temperature element 4 are connected to respectively on the binding post of joint sleeve 7, and pass and respectively be connected to two connection-pegs 9 with two strands of external cables 8 from joint sleeve 7 respectively.Be connected to the purpose that just can realize heating measuring and controlling temp on the heating temperature control instrument with above-mentioned two connection-pegs 9, to reach the optimum efficiency of thermotherapy.

The utility model compared with prior art not only can heat but also thermometric and reach the temperature control purpose but have, long service life, and good reliability is used the characteristics such as easy and simple to handle, safety.
