Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a warm sleeve that facilitates intensive blood collection in Phase I wards. Background Technology

[0002] Phase I clinical trials administer investigational drugs to healthy subjects under strictly controlled conditions. By monitoring drug concentration in the blood, excretion, and adverse reactions, the trials assess the human body's tolerance and pharmacokinetic characteristics of the new drug, thus providing a basis for developing a reasonable dosing regimen. Blood sample collection is a crucial step in this process. To reduce the physical pain and psychological fear caused by repeated punctures, a retractable intravenous catheter is usually implanted. However, with the limb exposed on the puncture side, subjects may feel cold and uncomfortable due to seasonal temperature changes and fasting, and may even experience vasospasm, leading to poor blood collection. In existing blood collection trials, hot water bottles, clothing, and other warming items are often used to alleviate local coldness, but these methods have many shortcomings. For example, hot water bottles may cause burns, the warming effect is short-lived, the temperature is unstable, and they need to be changed frequently, affecting the continuity of the trial and the comfort of the subjects.

[0003] Therefore, in response to the above problems, a warm sleeve that facilitates intensive blood collection in Phase I wards is now being developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing blood collection techniques, such as the potential for burns from hot water bottles, short duration of warmth, unstable temperature, and the need for frequent replacements, which affect the continuity of the test and the comfort of the subjects, this utility model provides a warming sleeve that is convenient for intensive blood collection in Phase I wards.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] A warming sleeve for intensive blood collection in Phase I wards includes an outer layer with an insulating layer attached to it. The insulating layer is made of fleece material, which is skin-friendly and warm, improving the comfort of the subject. Three first hook-and-loop fasteners are attached to the front left side of the insulating layer. The first hook-and-loop fasteners have a hook side. Three second hook-and-loop fasteners are attached to the rear right side of the outer layer. The second hook-and-loop fasteners have a fleece side. The first hook-and-loop fasteners interact with the second hook-and-loop fasteners. An interlayer is attached to the front right side of the insulating layer. Eight indwelling needle observation ports are provided on both the outer layer and the insulating layer. Adjacent indwelling needle observation ports correspond to each other. Grooves are provided on both the left and right sides of each indwelling needle observation port. Two needle auxiliary positioning ports are attached to the rear lower part of the outer layer.

[0007] Furthermore, a placement groove is provided on the inner side of the outer cladding layer, and the insulation layer is connected to the placement groove.

[0008] Furthermore, the outer cladding layer has a rectangular structure.

[0009] Furthermore, the outer layer is made of woven fabric.

[0010] Furthermore, the interlayer is pocket-shaped, which allows for better placement of heat packs.

[0011] Furthermore, it is characterized in that the observation port of the indwelling needle has a rhomboid structure.

[0012] By adopting the above technical solution, compared with the prior art, this utility model has the following advantages:

[0013] This invention improves the comfort of the subject by using a fleece material for the insulation layer, and the use of a heat pack in the interlayer ensures that the subject's arm remains warm during blood collection. In addition, the device has a simple structure, low cost, and can be used in a variety of ways. Attached Figure Description

Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] A type of warming sleeve for intensive blood collection in Phase I wards, such as Figures 1-3As shown, it includes an outer layer 1, which is rectangular in shape and made of fabric to better fit the subject's arm. An insulation layer 2, made of fleece, is attached to the outer layer 1 for skin-friendly warmth and to improve the subject's comfort. Three first hook-and-loop fasteners 3 are attached to the front left side of the insulation layer 2, with the first hook-and-loop fasteners 3 having a hook-and-loop surface. Three second hook-and-loop fasteners 4 are attached to the rear right side of the outer layer 1, with the second hook-and-loop fasteners 4 having a fleece surface. All the first hook-and-loop fasteners 3 are connected to the second hook-and-loop fasteners 4. The four layers interact with each other. The right front side of the insulation layer 2 is connected to the interlayer 5, which is pocket-shaped and can better hold the heat-insulating patch. There are eight observation ports 6 for indwelling needles on both the outer layer 1 and the insulation layer 2. The observation ports 6 are diamond-shaped and the adjacent observation ports 6 correspond to each other. There are slots 7 on the left and right sides of the observation ports 6. There are two needle auxiliary positioning ports 8 connected to the lower rear side of the outer layer 1. There is a placement groove 9 on the inner side of the outer layer 1, and the insulation layer 2 is connected to the placement groove 9.

[0020] It should be noted that during blood collection, subjects may experience coldness and discomfort due to exposure of the puncture side, seasonal temperature changes, and the effects of fasting, and may even experience vasospasm or difficulty in blood collection. To improve subject comfort and ensure smooth blood collection, this device can be used for assistance. First, place the insulation layer 2 of this device under the subject's arm, ensuring it fits snugly against the arm. The insulation layer 2 is made of skin-friendly fleece material with excellent warmth retention. The outer layer 1 is made of fabric, further enhancing the fit and effectively improving the subject's comfort. Next, place the preheated warming patch into the interlayer 5, which has a pocket-like structure for secure placement. A warming patch is placed to ensure the subject's arm remains warm during blood collection, preventing discomfort or vasoconstriction due to low temperature. Then, the warming layer 2 is rolled up, and the first Velcro 3 is attached to the second Velcro 4 to form a cylindrical shape. The combination of the three pairs of Velcro allows the sleeve to be adjusted according to the thickness of the subject's arm, ensuring a secure fit and preventing slippage. Next, the indwelling needle observation port 6 is adjusted according to the position of the indwelling needle to ensure that the status of the indwelling needle can be clearly observed through the indwelling needle observation port 6. At the same time, the indwelling needle tube is passed through the needle collection auxiliary positioning port 8 through the indwelling needle observation port 6 and fixed to the outer layer 1 to prevent the needle tube from swinging during blood collection, ensuring the stability and safety of the blood collection process.

[0021] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
