Embodiment Construction

[0072] Embodiments of the invention relate to a device for facilitating the introduction of an infusion set, particularly a cannula of an infusion set, into the subcutaneous layer of a patient's skin.

[0073] refer to figure 1 with 2 , which shows an example implementation of the device 100 . Device 100 is used to introduce a cannula of an infusion device, such as a set, positioning patch, or other access device, into the patient's skin. The sleeve, positional patch, or other access device can then be used to infuse medication or other fluids into the patient, such as from an infusion pump.

[0074] Device 100 generally includes a housing 110 , a cylindrical barrel 120 , a needle barrel 130 , a cannula 140 , a spring 150 , an adhesive portion 160 , and a cover 170 . Each component of device 100 is described further below and is configured to facilitate the introduction of a cannula of an infusion set into a patient's skin.

[0075] now refer to Figure 3-5 , which shows ...

Abstract

A device for inserting a cannula of a subcutaneous infusion device into a subcutaneous layer of skin of a patient. For example, some devices automatically retract a needle used to introduce the cannula of a subcutaneous infusion device into the subcutaneous layer of skin of a patient. The device can include a housing with an internal cavity, as well as a needle coupled to the housing. The needle can be coupled to a cannula of a subcutaneous infusion device. A member can move the needle. Upon full introduction of the needle and associated cannula of the subcutaneous infusion device into a subcutaneous layer of skin of a patient, the member is automatically actuated to move the needle into the internal cavity of the housing into the retracted state while leaving the cannula of the subcutaneous infusion device in the subcutaneous layer of skin of the patient.

Description

technical field [0001] The present invention relates to a device for facilitating the introduction of a cannula of an infusion set into the skin of a patient to infuse a substance into the patient. Background technique [0002] Infusion sets are used to infuse substances, such as drugs, into the subcutaneous layer of a patient's skin. Devices for facilitating the insertion of a cannula of an infusion set into the skin of a patient are known. For example, some devices use a spring to automatically drive a needle into the patient's skin, thereby guiding the cannula of the infusion set into the subcutaneous layer. [0003] Since the needle is used to introduce the cannula of the infusion set into the subcutaneous layer of the skin, there is a risk of inadvertent contact with the needle. Furthermore, prior to insertion, upon seeing the needle, the patient's reaction may be negative, eg, reluctance to place the needle in the skin. Prior art devices may not adequately shield th...
