Problems solved by technology

[0002] After long-term observation and experiments in the clinic, we found that there are many defects in the infusion devices connected with indwelling devices such as indwelling needles and central venous catheters in the current clinical infusion. However, the existing disclosed technical solutions are difficult to be practically applied and promoted due to structural or process problems, product production difficulties and operational performance defects. Their defects are:
[0003] 1. After the existing infusion needle is docked with the puncture connector of the indwelling device, there is no protection or fixing device, and it cannot be connected in the air, and can only be fixed on the human limb
[0004] 2. After the existing infusion needle is docked with the puncture-type connector of the indwelling device, the support points of the two on the human body are in different planes, and the use of adhesive tape cannot firmly fix the infusion needle seat and the puncture-type connector, making the root of the infusion needle easy to Under the breaking force, there is a phenomenon of broken needles
[0005] 3. Tape fixation, one is that patients need to accept more tapes, and it may also increase the chance of allergies, and the other is that the operation is more troublesome
[0006] 4. The existing unsafe and safe inf

Example Embodiment

[0042] Example 1: see attached figure 1 shown:

[0043] A special infusion needle for anti-needle puncture-type connectors, including a needle tube 2, a needle base 3, and an infusion catheter 4 connected to the rear end of the needle base 3, the needle tube 2 and the sheath 1 capable of accommodating the puncture-type connector are fixed on the needle base 3 on.

[0044] During production, a sheath 1 with a suitable length is prepared, and the needle hub 3 is bonded to the needle tube 2. After the needle tube 2 is silicified, the sheath 1 is directly sleeved or bonded to the front end of the needle hub 3, so that the entire needle tube 2 is placed in the sheath 1, play the role of anti-acupuncture. In use, the piercing end face of the puncture-type connector enters the bottom of the sheath 1 through the front opening 6 of the sheath 1 , and the puncture-type connector is fixed by using adhesive tape or utilizing the elasticity and friction of the sheath 1 itself. Since the...

[0045] Example 2: see attached figure 1 shown:

[0046] A special infusion needle for anti-needle puncture-type connectors, including a needle tube 2, a needle base 3, and an infusion catheter 4 connected to the rear end of the needle base 3, the needle tube 2 and the sheath 1 capable of accommodating the puncture-type connector are fixed on the needle base 3 on. After the puncture-type connector is inserted longitudinally into the sheath 1 , there is a maximum lateral movement distance of 0.5-2.5 mm between the puncture-type connector and the sheath 1 when there is no restriction of the needle tube 2 .

[0047] It is convenient for medical staff to operate, and at the same time, since the puncture-type connector is located in the tubular sheath 1, there is a maximum lateral movement distance of 0.5-2.5 mm between the puncture-type connector and the sheath 1 to prevent the needle tube 2 from repeatedly puncturing the puncture-type connector The center point of the infusion e...

Example Embodiment

[0048] Embodiment three: see attached figure 2 , 3 shown:

[0049] It includes a needle tube 2 , a needle base 3 , and an infusion catheter 4 connected to the rear end of the needle base 3 . The needle tube 2 and the sheath 1 capable of accommodating a piercing connector are fixed on the needle base 3 . In this example, the sheath 1 is made of soft material, but it has a certain deformation ability and elasticity, and it will not bend during normal use, so it can protect the steel needle and prevent acupuncture. Utilize its deformability plus at least one longitudinal opening 5 to ensure that it can accommodate piercing connectors within a certain range of deviation from the axis of the needle tube 2 or various specifications and piercing connectors on the Y-shaped indwelling needle.

[0050] During production, the sheath 1 can be prepared using an extruder, and the opening 5 can be punched out using a knife.

Abstract

The invention discloses a pricking preventing infusion needle special for a puncture type connecting piece. The pricking preventing infusion needle comprises a needle tube, a needle seat and an infusion catheter connected with the rear end of the needle seat and is characterized in that the needle tube and a sheath capable of containing the puncture type connecting piece are fixed to the needle seat. According to the pricking preventing infusion needle special for the puncture type connecting piece, the structure is simple and reasonable, the process is simple, manufacturing is easy, and a columnar handheld handle, a fixed part and a supporting part are arranged; the sheath which is provided with a side opening short needle, prevents pricking in the whole operation process and has expanding performance is adopted, the infusion needle can be connected with different positions of the puncture end face of the puncture type connecting piece and connected with the puncture type connecting piece on a Y-shaped remaining needle, and nosocomial infection and other matter entering the blood vessels of the human body can be reduced. The problem that no safe special infusion needle exists in existing clinical treatment can be solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a needle-puncture-proof puncture-type connector special infusion needle, which is specially used for infusion and blood transfusion of products equipped with puncture-type connectors. Background technique [0002] After long-term observation and experiments in the clinic, we found that there are many defects in the infusion devices connected with indwelling indwelling devices such as indwelling needles and central venous catheters in the current clinical infusion. However, the existing disclosed technical solutions are difficult to be practically applied and promoted due to structural or process problems, product production difficulties and operational performance defects. Their defects are: [0003] 1. After the existing infusion needle is docked with the puncture connector of the indwelling device, there is no protection or fixing device, and it cannot be connected in the air, an...
